Sentences containing predicates of personal taste (for example, ‘tasty’, ‘funny’) and aesthetic predicates (for example, ‘beautiful’) give rise to an acquaintance inference: They convey the information that speakers have first-hand experience with the object of predication and they can only be uttered appropriately if that is the case. This is surprisingly hard to explain. I will concentrate on aesthetic predicates, and firstly criticize previous attempts to explain the acquaintance phenomena. Second, I will suggest an explanation that rests (...) on a speech act theoretical version of hybrid expressivism, according to which, in uttering ‘X is beautiful’ speakers perform two illocutionary acts simultaneously: an expressive and an assertive one. I will spell out this suggestion in detail and defend it against objections. Considering puzzles related to the acquaintance inference will lead to a new argument for a promising version of hybrid expressivism in meta-aesthetics. (shrink)

Some assertions give rise to the acquaintance inference: the inference that the speaker is acquainted with some individual. Discussion of the acquaintance inference has previously focused on assertions about aesthetic matters and personal tastes (e.g. 'The cake is tasty'), but it also arises with reports about how things seem (e.g. 'Tom seems like he's cooking'). 'Seem'-reports give rise to puzzling acquaintance behavior, with no analogue in the previously-discussed domains. In particular, these reports call for (...) a distinction between the specific acquaintance inference (that the speaker is acquainted with a specific individual) and the general acquaintance inference (that the speaker is acquainted with something or other of relevance). We frame a novel empirical generalization -- the specific with stage-level generalization -- that systematizes the observed behavior, in terms of the semantics of the embedded 'like'-clause. We present supporting experimental work, and explain why the generalization makes sense given the evidential role of 'seem'-reports. Finally, we discuss the relevance of this result for extant proposals about the semantics of 'seem'-reports. More modestly, it fills a gap in previous theories by identifying which reports get which of two possible interpretations; more radically, it suggests a revision of the kind of explanation that should be given for the acquaintance behavior in question.

Simple sentences containing predicates like "tasty" and "beautiful" typically suggest that the speaker has first-hand knowledge of the item being evaluated. I consider two explanations of this acquaintance inference: a presuppositional approach and a pragmatic-epistemic approach. The presuppositional approach has a number of virtues, but runs into trouble because the acquaintance inference has a very different projection pattern from that of standard presuppositions. The pragmatic-epistemic approach accounts for the main data discussed in the paper, but faces (...) challenges of its own. (shrink)

Assertions about appearances license inferences about the speaker's perceptual experience. For instance, if I assert, 'Tom looks like he's cooking', you will infer both that I am visually acquainted with Tom (what I call the "individual acquaintance inference"), and that I am visually acquainted with evidence that Tom is cooking (what I call the "evidential acquaintance inference"). By contrast, if I assert, 'It looks like Tom is cooking', only the latter inference is licensed. I develop (...) an account of the acquaintance inferences of appearance assertions building on two main previous lines of research: first, the copy raising literature, which has aimed to account for individual acquaintance inferences through the "perceptual source" semantic role; second, the subjectivity literature, which has focused on the status of acquaintance inferences with predicates of personal taste, but hasn't given much attention to the added complexities introduced by appearance language. I begin by developing what I take to be the most empirically-sound version of a perceptual source analysis. I then show how its insights can be maintained, while however taking anything about perception out of the truth conditions of appearance sentences. This, together with the assumption that appearance assertions express experiential attitudes, allows us to capture the acquaintance inferences of bare appearance assertions without making incorrect predictions about the behavior of appearance verbs in embedded environments.

Aesthetic non-inferentialism is the widely-held thesis that aesthetic judgements either are identical to, or are made on the basis of, sensory states like perceptual experience and emotion. It is sometimes objected to on the basis that testimony is a legitimate source of such judgements. Less often is the view challenged on the grounds that one’s inferences can be a source of aesthetic judgements. This paper aims to do precisely that. According to the theory defended here, aesthetic judgements may be unreasoned, (...) insofar as they are immediate judgements made on the basis of, and acquiring their justification from, causally prior sensory states. Yet they may also be reasoned, insofar as they may be the outputs of certain inferences. Crucially, a token aesthetic judgement may be unreasoned and reasoned, simultaneously. A key reason for allowing inference a serious role in aesthetic judgements emerges from reflection upon the nature of aesthetic expertise. (shrink)

All cognitive consciousness, Professor Earle's realism asserts, is acquaintance with reality. Cognition is intrinsically "outside itself," for to be conscious is to have a part of reality as an object. Cognizing consciousness is any mode of intentionality which presents its subject with an object. Hence mind does not infer its way outside itself: it is always outside itself looking at an object. And all such objects without qualification have their own distinctive mode of being, and are independent of the (...) subject and its act of awareness. (shrink)

In this paper I argue that when one has an epiphany of the form ‘God is F’ upon having a sublime experience one can be accurately described as being acquainted with the fact that God is F as opposed to inferring that God is F from the experience at hand. To argue for this, I will, first, outline what a sublime experience is, in general, before outlining what a theistic sublime experience is in particular. Second, I will outline two ways (...) of understanding theistic sublime experiences. First, I will outline a model that I will call the ‘inference model’ which, put simply, says that when one has an epiphany of the form ‘God is F’, upon having a theistic sublime experience, one is drawing this conclusion via a process of ‘inference-to-the-best-explanation’ The sublime: From antiquity to the present, Cambridge University Press, Cambridge, 2012, p. 426). Second, I will outline an alternative model that I call the ‘acquaintance model’ which, put simply, says that no inferential process occurs when one has an epiphany of the form ‘God is F’ upon having a theistic sublime experience, but one is made directly aware of the fact that God is F. Third, and finally, I will respond to some objections to the acquaintance model. (shrink)

Chastain and Sawyer, among others, claim that direct cognitive relations can be initiated in evidence cases. Direct cognitive relations will here include Chastain’s knowledge-of and Sawyer’s trace-based acquaintance, as well as related notions such as having-in-mind and singular thought. Against this controversial claim, it is often objected that such cases are better understood as cases of inference rather than cases of direct thought. When one detects something by its footprint, the objection goes, one merely infers that it exists (...) rather than thinking of it directly. The goal of this paper is to analyze what is meant by the inference objection and consider several possible responses to it. Ultimately, I will not offer a knock-down argument against the inference explanation; in fact, I’ll try to explain why I suspect one isn’t possible. Instead, I’ll appeal to the possibility of misdescription and analogous cases involving non-human animals to show that the inference explanation is less plausible than the account to which it provides an alternative.

The deviation of mathematical proof—proof in mathematical practice—from the ideal of formal proof—proof in formal logic—has led many philosophers of mathematics to reconsider the commonly accepted view according to which the notion of formal proof provides an accurate descriptive account of mathematical proof. This, in turn, has motivated a search for alternative accounts of mathematical proof purporting to be more faithful to the reality of mathematical practice. Yet, in order to develop and evaluate such alternative accounts, it appears as a (...) necessary prerequisite to first possess a clear picture of what the deviation of mathematical proof from formal proof consists in. The present work aims to contribute building such a picture by investigating the relation between the elementary steps of deduction constituting the two types of proofs—mathematical inference and logical inference. Many claims have been made in the literature regarding the relation between mathematical inference and logical inference, most of them stating that the former is lacking properties that are constitutive of the latter. Such differentiating claims are, however, usually put forward without a clear conception of the properties occurring in them, and are generally considered to be immediately justified by our direct acquaintance, or phenomenological experience, with the two types of inferences. The present study purports to advance our understanding of the relation between mathematical inference and logical inference by developing a detailed philosophical analysis of the differentiating claims, that is, an analysis of the meaning of the differentiating claims—through the properties that occur in them—as well as the reasons that support them. To this end, we provide at the outset a representative list of the different properties of logical inference that have occurred in the differentiating claims, and we notice that they all boil down to the three properties of formality, generality, and mechanicality. For each one of these properties, our analysis proceeds in two steps: we first provide precise conceptual characterizations of the different ways logical inference has been said to be formal, general, and mechanical, in the philosophical and logical literature on formal proof; we then examine why mathematical inference does not appear to be formal, general, and mechanical, for the different variations of these notions identified. Our study results in a precise conceptual apparatus for expressing and discussing the properties differentiating mathematical inference from logical inference, and provides a first inventory of the various reasons supporting the observations of those differences. The differentiating claims constitute thus a set of data that any philosophical account of mathematical inference and proof purporting to be more faithful to mathematical practice ought to be able to accommodate and explain.

Can a belief source confer justification when we lack antecedent justification for believing that it’s reliable? A negative answer quickly leads to skepticism. A positive answer, however, seems to commit one to allowing pernicious reasoning known as “epistemic bootstrapping.” Puzzles surrounding bootstrapping arise because we illicitly assume either that justification requires doxastic awareness of a source’s epistemic credentials or that there is no requirement that a subject be aware of these credentials. We can resolve the puzzle by splitting the horns (...) and requiring a non-conceptual awareness of, or direct acquaintance with, a source’s legitimacy. Requiring non-conceptual as opposed to doxastic awareness halts the regress and avoids the skeptical results. On the other hand, requiring non-conceptual awareness also guarantees that we are aware of evidence for a source’s reliability prior to using that source to form justified beliefs; we thereby avoid the problem of allowing epistemic bootstrapping to generate the illicit gains in justification.

Conceptual change and its connection to the development of new seien tific theories has reeently beeome an intensively discussed topic in philo sophieal literature. Even if the inductive aspects related to conceptual change have already been discussed to some extent, there has so far existed no systematic treatment of inductive change due to conceptual enrichment. This is what we attempt to accomplish in this work, al though most of our technical results are restricted to the framework of monadic languages. We (...) extend Hintikka's system of inductive logic to apply to situations in which new concepts are introduced to the original language. By interpreting them as theoretica1 concepts, it is possible to discuss a number of currently debated philosophical and methodological problems which have previously escaped systematic and exact treatment. For instance, the role which seientific theories employing theoretical con cepts may play within inductive inference can be studied within this framework. From the viewpoint of seientific realism, sueh a study gives outlines for a theory of what we call hypothetico-induetive inference. Some parts of this work which are based on Hintikka's system of in ductive logic are fairly technical. However, no previous knowledge of this system is required, but, in general, acquaintance with the basic ideas of elementary logic and probability theory is suffieient. This work is part of a project, originated by Professors Jaakko Hintikka and Raimo Tuomela, concerning the role of theoretical concepts in science. (shrink)

A basic problem of daily life is determining who owns what. One way that people may solve this problem is by relying on a ‘first possession’ heuristic, according to which the first person who possesses an object is its owner, even if others subsequently possess the object. We investigated preschoolers’ use of this heuristic in five experiments. In Experiments 1 and 2, 3- and 4-year-olds inferred that an object was owned by the character who possessed it first, even though another (...) character subsequently possessed it. Two-year-olds also showed this bias, but only when the object was placed between the characters when children were asked about ownership. Experiment 3 ruled out the possibility that children’s bias to select the first possessor results from a tendency to select the character first associated with the object. Experiment 4 showed that 3- and 4-year-olds have difficulty disregarding the first possession heuristic, even when provided with evidence that the character who first possessed an object is not its owner. But Experiment 5 found that children can disregard the heuristic in at least some situations. These five experiments suggest that the first possession heuristic guides children’s ownership inferences. The findings provide the first evidence that preschoolers can infer who owns what, when not explicitly told, and when not reasoning about objects with which they are personally acquainted. (shrink)

Simple claims with the verb ‘seem’, as well as the specific sensory verbs, ‘look’, ‘sound’, etc., require the speaker to have some relevant kind of perceptual acquaintance (Pearson, 2013; Ninan, 2014). But different forms of these reports differ in their perceptual requirements. For example, the copy raising (CR) report, ‘Tom seems like he’s cooking’ requires the speaker to have seen Tom, while its expletive subject (ES) variant, ‘It seems like Tom is cooking’, does not (Rogers, 1972; Asudeh and Toivonen, (...) 2012). This contrast has led some theorists to hold that the matrix subject in CR constructions is uniformly interpreted as the perceptual source (p-source) (Asudeh and Toivonen, 2012; Rett and Hyams, 2014). Others, based on examples of CR reports that seem not to require perception of the referent of the matrix subject, have taken the p-source interpretation instead to be non-uniform across CR reports (Landau, 2011; Doran, 2015). We reconsider these theoretical approaches to copy raising in light of new experimental work probing the sensitivity of these requirements to the matrix verb, the embedded ‘like’-clause, and the context. While we find some motivation for a non-uniform p-source analysis, it comes from importantly different cases than those others have relied on. Furthermore, our findings cast doubt on the prevalent assumption that the perceptual requirements of CR reports are to be captured solely by the presence or absence of the p-source interpretation. We suggest that the data motivating a non-uniform p-source view are better captured by an alternative approach, which makes use of a more minimal evidential source role, in place of the perceptual source role. We close by considering the relationship between English copy raising and evidential constructions cross-linguistically. (shrink)

Simple taste predications come with an `acquaintance requirement': they require the speaker to have had a certain kind of first-hand experience with the object of predication. For example, if I tell you that the crème caramel is delicious, you would ordinarily assume that I have actually tasted the crème caramel and am not simply relying on the testimony of others. The present essay argues in favor of a lightweight expressivist account of the acquaintance requirement. This account consists of (...) a recursive semantics and an account of assertion; it is compatible with a number of different accounts of truth and content, including contextualism, relativism, and purer forms of expressivism. The principal argument in favor of this account is that it correctly predicts a wide range of data concerning how the acquaintance requirement interacts with Boolean connectives, generalized quantifiers, epistemic modals, and attitude verbs.

ABSTRACTEvaluative aesthetic discourse communicates that the speaker has had first-hand experience of what is talked about. If you call a book bewitching, it will be assumed that you have read the book. If you say that a building is beautiful, it will be assumed that you have had some visual experience with it. According to an influential view, this is because knowledge is a norm for assertion, and aesthetic knowledge requires first-hand experience. This paper criticizes this view and argues for (...) an alternative view, according to which aesthetic discourse expresses affective states of mind, analogously to how assertions express beliefs. It is because these affective states require first-hand experience that aesthetic discourse communicates that such acquaintance is at hand. The paper furthermore argues that the lack of an experience requirement for aesthetic belief ascriptions constitutes a problem for the kind of expressivist who claims that evaluative belief states are covert non-cognitive states.

This paper develops and motivates an Expressivist theory of "experiential" talk and thought, focusing on speech acts and thoughts that contain taste predicates. According to this theory, one way for S to think that o tastes a way w is simply for o to taste w to S. When o tastes w to S (and, therefore, S thinks that o tastes w), S can express this thought, by saying that o tastes w. The speech act wherein S expresses the thought (...) that o tastes w, so understood, must be distinguished from the speech act wherein S says or asserts that S tastes w to them. This paper develops a formal model of these informal claims, and it argues that the resulting theory fits well with the linguistic data -- no worse than the best propositional theories when it comes to representing quantificational readings of attitude ascriptions, and strictly better than the best propositional theories when it comes to representing non-quantificational ("experiential") readings.

ABSTRACT It has been frequently observed in the literature that assertions of plain sentences containing predicates like fun and frightening give rise to an acquaintance inference: they imply that the speaker has first-hand knowledge of the item under consideration. The goal of this paper is to develop and defend a broadly expressivist explanation of this phenomenon: acquaintance inferences arise because plain sentences containing subjective predicates are designed to express distinguished kinds of attitudes that differ from beliefs in (...) that they can only be acquired by undergoing certain experiences. Its guiding hypothesis is that natural language predicate expressions lexically specify what it takes for their use to be properly ‘grounded’ in a speaker's state of mind: what state of mind a speaker must be in for a predication to be in accordance with the norms governing assertion. The resulting framework accounts for a range of data surrounding the acquaintance inference as well as for striking parallels between the evidential requirements on subjective predicate uses and the kind of considerations that fuel motivational internalism about the language of morals. A discussion of how the story can be implemented compositionally and of how it compares with other proposals currently on the market is provided. (shrink)

To justify inductive inference and vanquish classical skepticisms about human memory, external world realism, etc., Richard Fumerton proposes his “inferential internalism,” an epistemology whereby humans ‘see’ by Russellian acquaintance Keynesian probable relations (PRs) between propositions. PRs are a priori necessary relations of logical probability, akin to but not reducible to logical entailments, such that perceiving a PR between one’s evidence E and proposition P of unknown truth value justifies rational belief in P to an objective degree. A recent (...) critic of inferential internalism is Alan Rhoda, who questions its psychological plausibility. Rhoda argues that in order to see necessary relations between propositions E and P, one would need acquaintance with too many propositions at once, since our evidence E is often complex. In this paper, I criticize Rhoda’s implausibility objection as too quick. Referencing the causal status effect (CSE) from psychology, I argue that some of the complex features of evidence E contribute to our type-categorizing it as E-type, and thus we do not need to ‘see’ all of the complex features when we see the PR between E and P. My argument leaves unchanged Fumerton’s justificatory role for the PR, but enhances its psychological plausibility. (shrink)

Utterances of simple sentences containing taste predicates (e.g. "delicious", "fun", "frightening") typically imply that the speaker has had a particular sort of first-hand experience with the object of predication. For example, an utterance of "The carrot cake is delicious" would typically imply that the speaker had actually tasted the cake in question, and is not, for example, merely basing her judgment on the testimony of others. According to one approach, this acquaintance inference is essentially an implicature, one generated (...) by the Maxim of Quality together with a certain principle concerning the epistemology of taste (Ninan 2014). We first discuss some problems for this approach that arise in connection with disjunction and generalized quantifiers. Then, after stating a conjecture concerning which operators ‘obviate’ the acquaintance inference and which do not, we build on Anand & Korotkova (2018) and Willer & Kennedy (Forthcoming) by developing a theory that treats the acquaintance requirement as a presupposition, albeit one that can be obviated by certain operators.

Dogmatism holds that an experience or seeming that p can provide prima facie immediate justification for believing p in virtue of its phenomenology. Dogmatism about perceptual justification has appealed primarily to proponents of representational theories of perceptual experience. Call dogmatism that takes perceptual experience to be representational "representational phenomenal dogmatism." As we show, phenomenal seemings play a crucial role in dogmatism of this kind. Despite its conventional appeal to representational theorists, dogmatism is not by definition committed to any particular view (...) of perceptual experience. Naive realists and disjunctivists who hold that perceptual experience is a perceptual relation of direct acquaintance can also endorse dogmatism. Indeed, we argue that they ought to do so. Otherwise, they cannot maintain that relationalism about perceptual experience has an epistemic advantage compared to the representational view. We then show that even if we grant that relationalism has this advantage, only dogmatism that takes perceptual experience to be representational can be extended to account for non-deductive inferential justification. As an account of the latter is required to avoid succumbing to skepticism, relationalism, we argue, does not have the epistemic advantage its defenders claim it has. (shrink)

Chalmers (The character of consciousness, 2010) argues for an acquaintance theory of the justification of direct phenomenal beliefs. A central part of this defense is the claim that direct phenomenal beliefs are cognitively significant. I argue against this. Direct phenomenal beliefs are justified within the specious present, and yet the resources available with the present ‘now’ are so impoverished that it barely constrains the content of a direct phenomenal belief. I argue that Chalmers’s account does not have the resources (...) for explaining how direct phenomenal beliefs support the inference from ‘this E is R’ to ‘that was R.’. (shrink)

Many currently working on a Russellian notion of perceptual acquaintance and its role in perceptual experience (including Campbell 2002a, 2002b, and 2009 and Tye 2009) treat naïve realism and indirect realism as an exhaustive disjunction of possible views. In this paper, I propose a form of direct realism according to which one is directly aware of external objects and their features without perceiving a mind-dependent intermediary and without making any inference. Nevertheless, it also maintains that the qualitative character (...) of perceptual experience is a feature of our internal states of sentient awareness and so is to be distinguished from the features of objects in the perceptual scene. On this proposal, we are pre-reflectively aware of the qualitative character of our sensations simply in virtue of having them, and we are non-inferentially aware of external objects and their features by being attuned to what the occurrence of our sensations tells us about the rest of the world. Consequently, we are presented with, and thus acquainted with, both the external objects and the qualitative character of our sensory experiences, albeit in very different ways. Drawing on resources from Perry (2001) and Searle (in draft), I explain how perceptual experience has this “two-faced presentational character”. (shrink)

METAPHYSICS, NATURE OF (Addendum) What is metaphysics? An answer to this question requires a specification both of the scope of metaphysics – that is, of the nature of the questions that metaphysicians raise and attempt to answer – and of the methods that they employ in this enterprise. The discussion falls into the following two parts: 1. The Scope of Metaphysics 2. The Methods of Metaphysics 1. The Scope of Metaphysics As regards the scope, a natural answer is that metaphysics (...) is concerned with the investigation of the ultimate nature of reality, where this involves the attempt, first, to arrive at the most fundamental truths about what exists, and second, to provide an account of the concepts that are involved in such fundamental truths. This leads immediately to the question of how metaphysics is related to science. For does not science also aim at discovering fundamental truths about reality? In response, it is suggested, first, that a central part of metaphysics involves offering accounts of concepts that are essential to scientific theories in general, but of which no account is offered within any of the sciences themselves. Then, secondly, philosophers attempt to establish necessary truths involving some of those concepts, at least some of which have no relevance to scientific theories, whereas science is typically silent on questions that have no bearing on the experimental content and predictions of scientific theories. Thirdly, physics and the other sciences involve presuppositions for which they offer no justification, such as that there is an external, physical world, whereas philosophers attempt to answer such questions. Fourthly, the sciences rely upon induction, in the form of the method of hypothesis, or inference to the best explanation, but, in contrast to philosophers do attempt to show that induction is justified – a question whose answer may very well turn upon metaphysical questions, such as that of the nature of laws of nature. 2. The Methods of Metaphysics In this second section, a number of methods that philosophers employ in metaphysics are described and discussed, including. The following: (1) The idea of direct acquaintance with mental entities. (2) The idea of direct perception of non-mental entities. (3) Various proposed inductive methods. (4) The derivation of analytical truths (5) The search for truthmakers. (6) The appeal to intuitions -/- . (shrink)

This chapter examines Bertrand Russell's developing views--roughly from 1911 to 1918--on the nature of introspective knowledge and subjects' most basic knowledge of themselves as themselves. It argues that Russell's theory of introspection distinguishes between direct awareness of individual psychological objects and features, the presentation of psychological complexes involving those objects and features, and introspective judgments which aim to correspond with them. It also explores his transition from believing that subjects enjoy introspective self-acquaintance, to believing that they only know themselves (...) by self-description, and eventually to believing that self-knowledge is a logical construction. It concludes by sketching how Russell's views about introspection and self-knowledge change as a result of his adoption of neutral monism. Along the way, it sheds additional light on his acquaintance-based theory of knowledge, preference for logical constructions over inferred entities, and gradual progression towards neutral monism.

A phenomenal concept is a concept that one possesses only if one has the relevant experience. In this essay, I argue that phenomenal concept theorists, namely, those who believe that we acquire phenomenal concepts through being acquainted with the relevant experience, can never succeed in determining which species of non-human animals are phenomenally conscious because they prohibit any a priori correlation between phenomenal and non-phenomenal concepts. I make my argument by first discussing several ways in which a phenomenal concept theorist (...) may explain which animal species are conscious, namely, with neuro-identity theory, behaviorism, and functionalism, and the problem that these approaches entail. I then illustrate how the alternative approaches of scientific inference to the best explanation, analogical inference, similarity inference, and inference by prototype face the same problem.

This book focuses on Russell's work from 1905 to 1919, during which period Russell attempted a reductionist analysis of empirical knowledge.

Gossip has been the object of a number of different studies in the past 50 years, rehabilitating it not only as something worth being studied, but also as a pivotal informational and social structure of human cognition: Dunbar (Rev Gen Psychol 8(2):100–110, 2004) interestingly linked the emergence of language to nothing less than its ability to afford gossip. Different facets of gossip were analyzed by anthropologists, linguists, psychologists and philosophers, but few attempts were made to frame gossip within an epistemological (...) framework (for instance Ayim in (Good gossip, pp. 85–99, 1994)). Our intention in this paper is to provide a consistent epistemological (applied and social) account of gossip, understood as broadly evaluative talk between two or more people, comfortably acquainted between each other, about an absent third party they are both at least acquainted with. Hence, relying on the most recent multidisciplinary literature about the topic, the first part of this paper will concern the epistemic dynamics of gossip: whereas the sociobiological tradition individuates in gossip the clue for the (theoretically cumbersome) group mind and group-level adaptations Wilson et al. (The evolution of cognition, pp. 347–365, 2002), we will suggest the more parsimonious modeling of gossip as a soft-assembled epistemic synergy, understood as a function-dominant interaction able to project a higher organizational level—in our case, the group as group-of-gossips. We will argue that the aim of this synergy is indeed to update a Knowledge Base of social information between the group (as a projected whole) and its members. The second and third part will instead focus on the epistemological labeling of the inferences characterizing gossip: our contention is that the ever-present moral/evaluative dimension in gossip—be it tacit or explicit, concerning the objects or the partners of gossip—is best analyzed through the epistemological framework of abduction. Consequently, we will suggest that a significant role of gossip is to function as a group-based abductive appraisal of social matter, enacted at various levels. (shrink)

Dr Edwards' stimulating and provocative book advances the thesis that the appropriate axiomatic basis for inductive inference is not that of probability, with its addition axiom, but rather likelihood - the concept introduced by Fisher as a measure of relative support amongst different hypotheses. Starting from the simplest considerations and assuming no more than a modest acquaintance with probability theory, the author sets out to reconstruct nothing less than a consistent theory of statistical inference in science.

Colour Relationalism asserts that colours are non-intrinsic or inherently relational properties of objects, properties that depend not only on a target object but in addition on some relation that object bears to other objects. The most powerful argument for Relationalism infers the inherently relational character of colour from cases in which one’s experience of a colour contextually depends on one’s experience of other colours. Experienced colour layering—say looking at grass through a tinted window and experiencing opaque green through transparent grey—demands (...) a contextual interdependency of one’s experience of one of these colours on one’s experience of the other. However, most if not all colour ontologies, and core perceptual experiential mechanisms like acquaintance and representation, can accommodate colour layering. It follows that experienced colour layering is consistent with colours being non-relational—this contextual interdependency of colours does not entail the constitutive dependency of one colour on the other. I utilize colour layering to examine the inference from the contextual to the constitutive interdependency of colours as it is employed in a well-known argument for Relationalism. I conclude that our justification for Relationalism is far weaker than Relationalists suggest. I first introduce readers to colour layering, then to Relationalism, and following this focus on the intersection of these topics. (shrink)

The central recommendation of this article is that philosophers trained in the analytic tradition ought to add the sensibilities and skills of the historian to their methodological toolkit. The value of an historical approach to strictly philosophical matters is illustrated by a case study focussing on the medieval origin of conceivability arguments and contemporary views of modality. It is shown that common metaphilosophical views about the nature of the philosophical enterprise as well as certain inference patterns found in thinkers (...) from Descartes to Chalmers have their origin in the theological concerns of the Scholastics. Since these assumptions and inference patterns are difficult to motivate when shorn of their original theological context, the upshot is that much post-Cartesian philosophy is cast in an altogether unfamiliar, and probably unwelcome, light. The methodological point, however, is that this philosophical gain is born of acquaintance with the history of ideas. (shrink)

The goal of this paper is to sketch an account of Kant’s signature metaphysical doctrine (transcendental idealism) that (a) has no supporters – as far as I am aware – in the contemporary literature, and (b) draws its primary motivation (as interpretation) from considerations regarding our practical situation and needs as agents. -/- The consideration I focus on here is that people not only have mental and moral features, but they also appear to us – in our daily experience – (...) to have such features: “[w]e can perceive virtue in our experience (Wir können in der Erfahrung wohl Tugend wahrnehmen)” (24: 906). The same presumably goes for vice: When I see you casually torturing a cat, you appear to me to be brown-haired, wearing jeans, moving your arms, laughing, and so on, but you also appear to me to be vicious and cruel. Your character shines through in your actions. I can then make a defeasible inference from those appearances to the moral reality. -/- Such appearances and inferences play a central role in our practices of praise, blame, forgiveness, and punishment. An interpretation of transcendental idealism that gives primacy to the practical will thus seek to analyze the concepts of experience, acquaintance, and appearance/phenomenon in a capacious-enough way that they can apply to mental and moral features too. If successful, such an interpretation would have a clear practical advantage over those that leave us merely conjecturing from experiences of bodies, gestures, and secondary qualities to moral features that do not appear, or even to the non-appearing features of a distinct set of things.

The dissertation addresses the mind-body problem, and in particular, the problem of how to fit phenomenal consciousness into the rest of reality. Phenomenal consciousness - the what it’s like feature of experience - can appear to the scientifically inclined philosopher to be deeply mysterious. It is difficult to understand how the swirl of atoms in the void, the oscillation of field values, the firing of synapses, or anything physical can add up to the smells, tastes, feelings, moods, and so forth (...) that comprise our phenomenal experience. There is a series of arguments - the so-called “Conceivability Arguments” - that spells out this puzzlement. If this arguments are successful then there is no place for phenomenal consciousness in a completely physical reality. The main conclusion of this dissertation is that the Conceivability Arguments are all dependent on a flawed premiss, and that therefore these arguments - perhaps the most powerful among anti-physicalist arguments - all fail. Conceivability Arguments begin with the premiss that we can conceive of any physical or functional facts obtaining without there being any phenomenal experience at all. This is sometimes expressed by saying that zombies (i.e., beings that are our physical and functional duplicates, but possess no phenomenal experiences) are conceivable. The claim that zombies are conceivable does not have to do with our powers of imagination, or our psychological abilities, but rather with the nature of physical and phenomenal concepts. The reason that zombies are claimed to be conceivable is that each person’s thinking about phenomenal properties is completely dependent on her first person acquaintance with her own experience. From this assertion of conceivability it is inferred that zombies are genuinely possible. And this conclusion is incompatible with physicalism as that doctrine is usually understood. I argue that these arguments all fail; they are refuted by a master argument that I call “the Zombie Refutation.” The reason they fail has to do with the very nature of phenomenal concepts that gives rise to the conceivability of zombies. Because of the special nature of these concepts, the principle underlying the Conceivability Arguments - that principle that links conceivability and possibility - turns out to be self-refuting. Thus, the zombies that the Conceivability Arguments supposedly demonstrate to be possible, return to undermine those very arguments; a fitting revenge. (shrink)

Girolamo Saccheri (1667--1733) was an Italian Jesuit priest, scholastic philosopher, and mathematician. He earned a permanent place in the history of mathematics by discovering and rigorously deducing an elaborate chain of consequences of an axiom-set for what is now known as hyperbolic (or Lobachevskian) plane geometry. Reviewer's remarks: (1) On two pages of this book Saccheri refers to his previous and equally original book Logica demonstrativa (Turin, 1697) to which 14 of the 16 pages of the editor's "Introduction" are devoted. (...) At the time of the first edition, 1920, the editor was apparently not acquainted with the secondary literature on Logica demonstrativa which continued to grow in the period preceding the second edition \ref[see D. J. Struik, in Dictionary of scientific biography, Vol. 12, 55--57, Scribner's, New York, 1975]. Of special interest in this connection is a series of three articles by A. F. Emch [Scripta Math. 3 (1935), 51--60; Zbl 10, 386; ibid. 3 (1935), 143--152; Zbl 11, 193; ibid. 3 (1935), 221--333; Zbl 12, 98]. (2) It seems curious that modern writers believe that demonstration of the "nondeducibility" of the parallel postulate vindicates Euclid whereas at first Saccheri seems to have thought that demonstration of its "deducibility" is what would vindicate Euclid. Saccheri is perfectly clear in his commitment to the ancient (and now discredited) view that it is wrong to take as an "axiom" a proposition which is not a "primal verity", which is not "known through itself". So it would seem that Saccheri should think that he was convicting Euclid of error by deducing the parallel postulate. The resolution of this confusion is that Saccheri thought that he had proved, not merely that the parallel postulate was true, but that it was a "primal verity" and, thus, that Euclid was correct in taking it as an "axiom". As implausible as this claim about Saccheri may seem, the passage on p. 237, lines 3--15, seems to admit of no other interpretation. Indeed, Emch takes it this way. (3) As has been noted by many others, Saccheri was fascinated, if not obsessed, by what may be called "reflexive indirect deductions", indirect deductions which show that a conclusion follows from given premises by a chain of reasoning beginning with the given premises augmented by the denial of the desired conclusion and ending with the conclusion itself. It is obvious, of course, that this is simply a species of ordinary indirect deduction; a conclusion follows from given premises if a contradiction is deducible from those given premises augmented by the denial of the conclusion---and it is immaterial whether the contradiction involves one of the premises, the denial of the conclusion, or even, as often happens, intermediate propositions distinct from the given premises and the denial of the conclusion. Saccheri seemed to think that a proposition proved in this way was deduced from its own denial and, thus, that its denial was self-contradictory (p. 207). Inference from this mistake to the idea that propositions proved in this way are "primal verities" would involve yet another confusion. The reviewer gratefully acknowledges extensive communication with his former doctoral students J. Gasser and M. Scanlan. ADDED 14 March 14, 2015: (1) Wikipedia reports that many of Saccheri's ideas have a precedent in the 11th Century Persian polymath Omar Khayyám's Discussion of Difficulties in Euclid, a fact ignored in most Western sources until recently. It is unclear whether Saccheri had access to this work in translation, or developed his ideas independently. (2) This book is another exemplification of the huge difference between indirect deduction and indirect reduction. Indirect deduction requires making an assumption that is inconsistent with the premises previously adopted. This means that the reasoner must perform a certain mental act of assuming a certain proposition. It case the premises are all known truths, indirect deduction—which would then be indirect proof—requires the reasoner to assume a falsehood. This fact has been noted by several prominent mathematicians including Hardy, Hilbert, and Tarski. Indirect reduction requires no new assumption. Indirect reduction is simply a transformation of an argument in one form into another argument in a different form. In an indirect reduction one proposition in the old premise set is replaced by the contradictory opposite of the old conclusion and the new conclusion becomes the contradictory opposite of the replaced premise. Roughly and schematically, P,Q/R becomes P,~R/~Q or ~R, Q/~P. Saccheri’s work involved indirect deduction not indirect reduction. (3) The distinction between indirect deduction and indirect reduction has largely slipped through the cracks, the cracks between medieval-oriented logic and modern-oriented logic. The medievalists have a heavy investment in reduction and, though they have heard of deduction, they think that deduction is a form of reduction, or vice versa, or in some cases they think that the word ‘deduction’ is the modern way of referring to reduction. The modernists have no interest in reduction, i.e. in the process of transforming one argument into another having exactly the same number of premises. Modern logicians, like Aristotle, are concerned with deducing a single proposition from a set of propositions. Some focus on deducing a single proposition from the null set—something difficult to relate to reduction. (shrink)

Epistemic Indirect Realism is the position that justification for contingent propositions about the extra-mental world requires an inference based on a subjective, experiential mental state. One objection against EIR is that it runs contrary to common sense and practice; in essence, ordinary people do not form beliefs about things in the external world on the basis of experiential mental states. This objection implies EIR is contrary to ordinary experience, impractical, and leads to scepticism. In this paper, I will defend (...) EIR against this objection by distinguishing EIR based on conceptual awareness and non-conceptual awareness. In particular, I will argue that direct acquaintance provides sufficient awareness that can explain how ordinary folks are capable of forming justified beliefs about the external world in a way consistent with EIR. Overall, I present a framework for showing that EIR can satisfy ordinary epistemic practices without betraying human nature or over-intellectualizing the required epistemic standards for possessing a justified belief.

Among the key factors that play a crucial role in the acquisition of knowledge, Buddhist philosophers list (i) the testimony of sense experience, (ii) introspective awareness (iii) inferences drawn from these directs modes of acquaintance, and (iv) some version of coherentism, so as guarantee that truth claims remains consistent across a diverse philosophical corpus. This paper argues that when Buddhists employ reason, they do so primarily in order to advance a range of empirical and introspective claims. As a result, (...) reasoning, in particular inductive reasoning on the testimony of perception, is based on a theory of causation. (shrink)

Defining "directly perceive" is made hard enough by the confused and vague ways in which philosophers have used the term, but it is made even more difficult by the fact that it is used quite differently by different philosophers. Two philosophers whose philosophy depends upon a clear understanding of direct perception are Berkeley and Russell. Consider what they say that is relevant to an understanding of their uses of the term. Berkeley, through Philonous, asks Hylas, "Are those things only perceived (...) by the senses which are perceived immediately? Or may those things properly be said to be ’sensible’ which are perceived mediately, or not without the intervention of others?" Russell, in speaking of knowledge by acquaintance, says that "we have acquaintance with anything of which we are directly aware, without the intermediary of any process of inference or any knowledge of truths. Thus in the presence of my table I am acquainted with the sense-data that make up the appearance of my table." Another quite common interpretation is given by Norman Malcolm, who states the definition "A directly perceives x if and only if A’s assertion that he perceives x could not be mistaken.". (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 1, April 2003, pp. 43-61 Conceivability and Modality in Hume: A Lemma in an Argument in Defense of Skeptical Realism PETER KAIL Introduction: A Realist View of Necessity and the Key Objection Those who seek to defend a skeptical realist reading of Hume on causal necessity have a number of textual and philosophical hurdles to clear. This paper attempts to clear one and only (...) one hurdle. So one should not look here for a complete case in favor of a skeptical realist reading: I merely attempt to dispose of what looks like a decisive objection to a conception of objective necessary connection which, I believe, Hume endorses. The skeptical realist Hume, as I and others read him, is a Hume who wishes to deny that human beings have the cognitive wherewithal to perceive or grasp the necessary connection which relates the objects of genuine causal relations. His "skeptical conclusion" is that we cannot grasp in re necessity, nor that there is no necessity. That bald statement, of course, leaves us with a whole host of questions: why should we think that Hume believes that there really is causal necessity? Is this position compatible with his positive account of our idea of necessary connection, or his theory of belief (and of ideas in general)? What of Hume's talk of "necessity in the objects" lacking a meaning? And how does Peter Kail is Lecturer in the Department of Philosophy, The University of Edinburgh, David Hume Tower, George Square, Edinburgh ΕΗ8 9JX, United Kingdom, e-mail: [email protected] 44 Peter Kail such a skeptical realist reading mesh with Hume's general philosophical project (or, indeed, what does it tell us about that)? None of these questions can be addressed here.1 Instead, as I said, I want to defend a conception of necessary connection that seems vulnerable to a decisive objection. First, then, I need to spell out what that conception is. Hume takes acquaintance with necessary connection (the "power, force or efficacy") to entail certain conceptual-cum-epistemological consequences. Roughly, acquaintance with necessary connection would entail (a) the possibility of a priori knowledge of the relevant cause's effect and (b) the impossibility of conceiving the cause without its effect. He tells us that: From the first appearance of an object, we can never conjecture what effect will result from it. But were the power or energy of any cause discoverable by the mind, we could foresee the effect, even without experience; and might, at first, pronounce with certainty concerning it, by the mere dint of thought and reasoning. (EHU 7.1.7; SBN 63) A similar claim is made in the Treatise: We must distinctly and particularly conceive the connection betwixt cause and effect, and be able to pronounce, from a simple view of the one, that it must be follow'd or preceded by the other. This is the true manner of conceiving a particular power in a particular body. (T 1.3.14.13; SBN 161) These aspects of Hume's treatment of necessity constitute what Galen Strawson has called the "AP Property."2 Notice that the AP Property furnishes a thin, but nevertheless contentful, specification of that of which we are ignorant when Hume says we are ignorant of necessary connection. Necessary connection is that feature, acquaintance with which, would yield what is specified in the AP Property. One can go further by suggesting that what the AP Property picks out are unknown (and, for reasons of deep contingency, unknowable) essences.3 This thought is intimated by a number of things Hume says: 'Tis easy to observe, that in tracing this relation, the inference we draw from cause to effect, is not deriv'd merely from a survey of these particular objects, and from such a penetration into their essences as may discover the dependence of the one upon the other. (T 1.3.6.1; SBN 86 (my emphasis)) Hume Studies Conceivability and Modality 45 And: It has been observ'd already, that in no single instance the ultimate connexion of any objects is discoverable, either by our senses or reason, and that we can never penetrate...

According to illusionism, phenomenal consciousness is an introspective illusion. The illusion problem is to explain the cause of the illusion, or why we are powerfully disposed to judge—erroneously—that we are phenomenally conscious. I propose a theory to solve the illusion problem. I argue that on the basis of three hypotheses about the mind—which I call introspective opacity, the infallibility intuition, and the justification constraint—we can explain our disposition, on introspection, to draw erroneous unconscious inferences about our sensory states. Being subject (...) to the illusion of phenomenal consciousness consists in having this disposition. I explain our ‘problem intuitions’ about consciousness —that our sensory states bear phenomenal properties that are qualitatively like something with which we are directly acquainted that is ineffable, atomic, intrinsic, private, and non-physical. I also address the illusion meta-problem, which is to explain why illusionism seems especially counterintuitive. (shrink)

Memory, of course, is not a trivial or isolated act, and therefore truth or falsity in descriptions of memory will have consequences for large reaches of our philosophical theory. Memory at least purports to give us our only direct knowledge of the past. And our only indirect knowledge of the past, through inference, must credit some memories somewhere. If then our knowledge of the past is vitiated, what remains of our knowledge of the present, or our expectations for the (...) future? But if memory lives up to its pretentions of acquainting us with the past, then what sort of world is it where an existent mind now can become directly acquainted with what is no more existent, but passed away? What in other words, are the ontological presuppositions of the act of memory? (shrink)

English summary: It was not until the publication of Schelling''s Munich and Berlin lectures that we learned the decisive source for his theory of an identity of identity or identity doubled in itself. Schelling referred to what he called an older logic that was still acquainted with the figure of reduplication, for instance in Leibniz and Wolff. Philosophers in this tradition employed this term to refer to the specification of an aspect under which the subject-term is being considered. An often (...) quoted example: As consul, Fabius Maximus has authority over his father, but as son he stands under his fathers authority. Schelling gave the following turn to reduplication: Nature as nature does not coincide with the mind; and the mind as mind does not coincide with nature. Both have different truth conditions, so as to integrate an essential moment of difference into the identity formula. There is an X, however, which is strictly (seamlessly) identical with itself (the absolute subject = X) while transitively being both of them in turn; and it is only via X that the relata (nature and mind) are indirectly identified with each other: X is B and X is A (and X is strictly identical to itself). In addition to this, Schelling held a view of predication as kind of identification. He became acquainted with this view at the Tubingen Seminary through his teacher Gottfried Ploucquet. This insight helps us understand why Schelling reasonably thought that the identity-formula A=A is the genuine matrix of all veridical judgments. Taken together with his conviction that judging (Kant''s relative position) is a minor (or inferior) form of existential being (Kant''s absolute position) sheds light on why in 1806 Schelling made the radical contention in his Aphorisms: The strict sense of being (absolutely posited seamless self-sameness) is taken over by the looser sense of the copulative is which identifies subject and predicate; yes, this copula alone is existence itself and nothing else. Why should Schelling''s conception of nature-mind identity interest recent philosophers of mind? Because Schelling presents an ontologically neutral solution: Identity is a symmetrical relation that does not favor mind or matter, and prevents the idealistic reduction of nature to the mind. Nor can we conceive of the nature-mind identity as a fact inwardly disclosed to the mind (McGinn, Levine). Consciousness remains an enigma for itself; so does its identity with nature. Schelling teaches us that identity theories are not justified by self-evidence, but by an inference to the best explanation. German description: Nie ist genau erklart worden, was Schelling unter Identitat von Natur und Geist verstand. Dabei hat er sein reifes Denken Identitatssystem genannt und sich zeitlebens um kein zweites Problem begrifflich ahnliche Muhe gegeben. Da er aber seine Uberlegungen in Schriften verpackte, deren grosser systematischer Ausgriff sie schier erdruckte, ist, was er bis hinein in die Weltalter-Periode daruber herausfand, kaum eigens gewurdigt oder auch nur klar benannt worden. Die Schellingliteratur arbeitete entweder historisch oder liess sich vom Systemgedanken oder einzelnen in die Augen springenden Problemen blenden (z. B. Natur, Organismus, Freiheit, Existenz). Dabei ist Schellings Starke in einzelnen entscheidenden Argumenten versteckt, die, waren sie bekannt, die gegenwartige, auch analytische Diskussion durchaus zu inspirieren vermochten. Wir konnen heute urteilen, dass schon der junge Schelling in seiner Schrift Form der Philosophie eine differenzsensitive Form der Identitat im Sinn hatte, die er in den kommenden Jahrzehnten immer genauer auszubuchstabieren unternahm. Seine eigentlichen Quellen hat er kunstvoll verborgen. Es sind erstens die Identitatstheorie der Pradikation seines Universitatslehrers Ploucquet, die den Stiftlern in Tubingen eingeblaut wurde und die ihre merkwurdige Fixierung auf die ganz unkantische Auffassung vom Urteil als Subjekt-Pradikat-Identifikation (mit quantifiziertem Pradikator) erklart. Und zweitens Schellings Entdeckung einer alteren Logik, die mit der Figur der reduplicatio arbeitete. - So auch das Absolute: Als Geist ist es nicht Natur (und umgekehrt; Aussagen uber beide haben unterschiedliche Wahrheitsbedingungen), aber Geist und Natur werden beide vom Absoluten gewesen (transitiv ins Sein gehoben), und dies Absolute ist im striktest denkbaren Sinne mit sich identisch. So lasst sich die Schelling''sche Formel von der Identitat der Identitat und Differenz dem gesunden Menschenverstand vermitteln und Schellings aufrichtiger Jugendgedanke (Marx) aktualisieren. Er schneidet respektabel ab im Wettbewerb mit allerlei heutigen Leib-Seele-Identitatstheorien. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:David Hume and the Probability of Miracles Barry Gower 1. Introduction Oflate there have been published several discussions ofDavid Hume's famous essay "Of Miracles" which attempt to make precise the reasoning it contains. This, it turns out, requires the use of certain mathematical rules and theorems of the probability calculus which were unknown to Hume or, indeed, to anyone else when the essay was first published. It is suggested, (...) in particular, that the claims he made can best be understood in the light of a theorem of the probability calculus which we now name after a celebrated eighteenth century probabilist, Thomas Bayes. However, the so-called "Bayesian" interpretation of the argument against miracles misrepresents Hume's reasoning in that the manner in which he expressed his thinking does not fit such an interpretation. Moreover, this error needs to be rectified, not just because it involves a mistaken view about the past but, more importantly, because it obscures the legacy of a different mode of thinking evident in Hume's writing about probabilistic inference which deserves to be recovered. Our thinkingisimpoverishedifcertain presumptions aboutprobability become so entrenched that we have great difficulty in seeing them as anything other than obvious. By imputing them to Hume we overlook their contestability and so lose an opportunity to recapture an alternative way of understanding probabilistic reasoning. As is well known, the argument against miracles, though not published until 1748, had been worked out some twelve or thirteen years earlier during Hume's stay at the Jesuit college of La Fleche, where he wrote most of A Treatise of Human Nature. A chapter entitled "Reasonings concerning Miracles" had been written but, at the last moment, it was suppressed for fear that such an explicit attack on religion would give offence and thus deflect attention from the book's main philosophical aim which was to put an end to controversy. On the other hand, Thomas Bayes's famous memoir on probability was not published until 1764, andit is unlikely that Hume knew ofits existence until Richard Price mentionedit, though without identifyingits author, in an elaborate mathematical footnote to a dissertation containing remarks on the probability of miracles, published in 1767. Had Hume taken the trouble to follow up this reference, he would almost certainly Volume XVI Number 1 17 BARRY GOWER have been either baffled by its mathematics or discouraged by its lack of practical advice. That, at least, seems to have been the reaction of Hume's contemporaries, for apart from Price none of them seems to have paid any attention to the memoir. Even today, when anyone with the slightest acquaintance with probability can recite a version of Bayes's theorem, it is hard to follow the reasoning of the memoir and to appreciate the significance of the ideas it contains. As an historian of statistics has recently said, "Bayes's contemporaries were stymied by the work, and modern readers unwilling to devote many hours to it are likely to gain only a superficial understanding ofit." One paradoxical feature of attributing Bayesianism to Hume concerns the role of Richard Price. His dissertation, which had, it seems, been written some years before it was published — perhaps in the early 1750's — is sharply critical of Hume's argument against miracles. Yet it was Price himself who was responsible for the posthumous publication of Bayes's memoir, and his introduction and commentary clearly express approval of its methods and conclusions. We are, then, faced with the suggestion that Hume, not having heard of Bayes, was applying Bayesian ideas about "inverse" inference to miraculous events, whereas Price, who was not only familiar with but also endorsed Bayes's ideas, preferred a quite different approach to reasoning about miracles and about the credibility of testimony generally. Can Hume really be described as a "better intuitive Bayesian" than Price? Before embracing such aparadoxical conclusion we should consider whether it is really justified by what Hume said about the probability ofmiracles. First, though, some attention needs to be paid to a way ofthinking about probable arguments which does not conform to convention, and which implies a non-Bayesian interpretation of the question about miracles. 2.

Three kinds of knowledge usually recognised by epistemologists are identified and their relevance for curriculum design is discussed. These are: propositional knowledge, know-how and knowledge by acquaintance. The inferential nature of propositional knowledge is argued for and it is suggested that propositional knowledge in fact presupposes the ability to know how to make appropriate inferences within a body of knowledge, whether systematic or unsystematic. This thesis is developed along lines suggested in the earlier work of Paul Hirst. The different (...) kinds of know-how and their relationships are discussed and it is suggested that they occupy different places and different relationships in any curricular hierarchy. The changing role that knowledge by acquaintance plays within this hierarchy is also discussed. Implications of this account for the current National Curriculum and for curriculum design more generally are discussed, looking at History, Science and Design Technology as examples. (shrink)

Traditionally the modern theory of ideas has been discussed primarily in reference to its alleged introduction of a veil of mental items between the mind and the world, which leads, through the empiricists, to radical skepticism about the existence of an external world. Here I propose to emphasize an entirely different aspect of the Cartesian theory of ideas which, in my view, is more fundamental in opening the empiricist path that leads to Hume’s radical skepticism. I argue that what I (...) call the “phenomenological presentation” model of ultimate justification is rooted in a fundamental ambiguity between sensible and intellectual apprehension insinuated by Descartes’s view of “clear and distinct” ideas together with his emphasis on the priority of intuition over logical inference. Sensible apprehension relies on immediate acquaintance with items phenomenologically and ostensively present before the mind as given particulars. The phenomenological presentation model takes its clues from sensible apprehension, although the items present before the mind might themselves be either ideas of the understanding, images of the imagination, sensory impressions, or material external objects. Intellectual apprehension, by contrast, as I illustrate with Leibniz’s model of our knowledge of concepts and truths of reason, consists in the discursive, non-ostensive grasping of the generality of abstract concepts and of formal structures . For Leibniz, all intellectual apprehension is unambiguously “logical discursive apprehension” as opposed to “direct ostensive apprehension.” Thus, Leibniz unmistakably disambiguates Descartes’s model in favor of a precise intellectual model. The empiricists, by contrast, correspondingly disambiguate Descartes’s conception in favor of an entirely sensible model. (shrink)

Aqui eu proponho enfatizar um aspecto completamente diferente da teoria Cartesiana das idéias que, na minha visão, é mais fundamental no que diz respeito a abrir o caminho empirista que conduz ao ceticismo radical de Hume. Eu argumento que o que eu chamo de o modelo de “apresentação fenomenológica” de justificação última está baseado em uma ambigüidade fundamental entre apreensão sensível e intelectual insinuada pela visão de Descartes de idéias “claras e distintas” junto com a sua ênfase na prioridade da intuição sobre inferência lógica. A apreensão sensível confia no contato imediato com itens presentes fenomenologicamente e ostensivamente perante a mente como particulares dados. O modelo de apresentação fenomenológica está inspirado na apreensão sensível, embora os itens que se apresentam perante a mente poderiam ser eles mesmos idéias do entendimento, figuras da imaginação, impressões sensórias, ou objetos externos materiais. A apreensão intelectual, por contraste, como eu ilustro com o modelo de Leibniz de nosso conhecimento de conceitos e verdades da razão, consiste na compreensão discursiva e não-ostensiva da generalidade de conceitos abstratos e de estruturas formais . Para Leibniz, toda a apreensão intelectual é claramente “apreensão discursiva lógica” por oposição a “apreensão ostensiva direta”. Assim, Leibniz claramente desfaz a ambigüidade do modelo de Descartes em favor de um modelo intelectual preciso. Os empiristas, por contraste, desfazem a ambigüidade da concepção de Descartes em favor de um modelo completamente sensível. (shrink)

"Introspection" in its broad sense (Shoemaker, Armstrong) is each non-inferential access a person has to his/her own current mental states and events. It includes both introspection as a conscious act and introspection as pre-introspective awareness. "Introspection" in its narrow sense (Ryle, Dretske, Dennett) excludes pre-intro-spective awareness as not self-sufficient kind of access and part of some other conscious act. Introspection as a self-sufficient conscious act can be explained as second-order thought or reduced to third person knowledge but pre-introspective awareness can (...) not (it is left as a mystery). Author claims that either pre-introspective awareness deserves the name "experience" and in source of special first-person knowledge (even if it is part of other sources of knowing and can be brought to consciousness only by proper introspection), either introspection as an act is a kind of experience and source of knowledge (sense experience is also some very fast interpretation of stimuli). Both pre-introspective awareness and proper introspection are kinds of experience if experience equals direct acquaintance, without any inference and stages. "Perception" can be left for sense perception of external objects. The result of introspection are not incorrigible but persons have "privileged access" to their own thoughts. (shrink)

I would like to propose a demonstrative transparency model of our immediate, introspective self-knowledge of experiences. It is a model entirely in line with transparency. It rests on three elements: mental demonstration, the capacity to apply concepts to what is given in experience, and ordinary inference. The model avoids inner sense, acquaintance, and any special kind of normativity or rationality. The crucial and new ingredient is mental demonstration. By mental demonstration we can refer indexically to the contents of (...) our own experiences in a unique way. This allows for the application of ordinary, non-mental concepts in order to arrive at a judgment about what it is that one is experiencing. In a transparent way one can then move inferentially to the self-ascription of an experience with such a content. I compare the demonstrative model with other accounts of introspective self-knowledge. (shrink)
