I will explore the paradoxical nature of epistemic access. By critiquing the traditional conception of mental states that are labelled as ’knowledge’, I demonstrate the susceptibility of these states to an infinite regress, thus, challenging their existence and validity. I scrutinise the assumption that an epistemic agent can have complete epistemic access to all facts about a given object while simultaneously being ignorant of certain truths that impact the very knowledge claims about the object. I further (...) analyse the implications of this paradox when attempting to fine-grain the parameters of epistemic access, which happens to reveal the vacuity of such definitions and the inevitability of the regress.

How should we understand validity? A standard way to characterize validity is in terms of the preservation of truth (or truth in a model). But there are several problems facing such characterizations. An alternative approach is to characterize validity epistemically, for instance in terms of the preservation of an epistemic status. In this paper, I raise a problem for such views. First, I argue that if the relevant epistemic status is factive, such as being in (...) a position to know or having conclusive evidence for, then the account runs into trouble if we endorse certain familiar logical principles. Second, I argue that if the relevant epistemic status is non-factive, such as is rationally committed to or has justification for believing, then a similar problem arises if we endorse the logical principles as well as a sufficiently strong epistemic “level-bridging” principle. Finally, I argue that an analogous problem arises for the most natural characterization of validity in terms of rational credence. (shrink)

Naturalism is the philosophical thesis that holds the following assumptions: the rejection of the supernatural and the transcendent; the acceptance of science as knowledge of high epistemic value, for some philosophers it is the only valid knowledge, and the rejection of all first or a priori philosophy. The problem addressed is that prima facie it seems problematic to explain the theses of naturalism without violating some of its assumptions. This paper will show that, starting from liberal naturalism and the (...) notions of niche construction, as well as some theses of the articulation of thought through language, it is possible to define naturalism without defending premises that violate its methodology.

In this work, quantum theories are considered which consist in essence of a map from state preparation proceduresw to states and a map from decision proceduresQ to probability operator measures. Two definitions of validity, similar to that given elsewhere, are given and compared for these theories. One definition is given in terms of one carrying out of somew followed by someQ, denoted by(Q, w). The other is given in terms of infinite repetitions(Q, w) ofw followed byQ. Both (...) class='Hi'>definitions are discussed in terms of the comparison of limit empirical means with theoretical expectation values. Particular attention is given to the use of outcome sequences of(Q, w) and of(Q, w) to determine properties of the probability measures the physical theory assigns to each(Q, w) in its domain.

The traditional picture of logic takes it for granted that "valid arguments have a fundamental epistemic significance", but neither model theory nor traditional proof theory dealing with formal system has been able to give an account of this significance. Since valid arguments as usually understood do not in general have any epistemic significance, the problem is to explain how and why we can nevertheless use them sometimes to acquire knowledge. It is suggested that we should distinguish between arguments (...) and acts of inferences and that we have to reconsider the latter notion to arrive at the desired explanation. More precisely, the notions should be developed so that the following relationship holds: one gets in possession of a ground for a conclusion by inferring it from premisses for which one already has grounds, provided that the inference in question is valid. The paper proposes explications of the concepts of ground and deductively valid inference so that this relationship holds as a conceptual truth. Logical validity of inference is seen as a special case of deductive validity, but does not add anything as far as epistemic significance is concerned—it resides already in the deductively valid inferences. (shrink)

The problem analysed in this paper is whether we can gain knowledge by using valid inferences, and how we can explain this process from a model-theoretic perspective. According to the paradox of inference (Cohen & Nagel 1936/1998, 173), it is logically impossible for an inference to be both valid and its conclusion to possess novelty with respect to the premises. I argue in this paper that valid inference has an epistemic significance, i.e., it can be used by an agent (...) to enlarge his knowledge, and this significance can be accounted in model-theoretic terms. I will argue first that the paradox is based on an equivocation, namely, it arises because logical containment, i.e., logical implication, is identified with epistemological containment, i.e., the knowledge of the premises entails the knowledge of the conclusion. Second, I will argue that a truth-conditional theory of meaning has the necessary resources to explain the epistemic significance of valid inferences. I will explain this epistemic significance starting from Carnap’s semantic theory of meaning and Tarski’s notion of satisfaction. In this way I will counter (Prawitz 2012b)’s claim that a truth-conditional theory of meaning is not able to account the legitimacy of valid inferences, i.e., their epistemic significance. (shrink)

There is no satisfactory account for the general phenomenon of confabulation, for the following reasons: (1) confabulation occurs in a number of pathological and non-pathological conditions; (2) impairments giving rise to confabulation are likely to have different neural bases; and (3) there is no unique theory explaining the aetiology of confabulations. An epistemic approach to defining confabulation could solve all of these issues, by focusing on the surface features of the phenomenon. However, existing epistemic accounts are unable to (...) offer sufficient conditions for confabulation and tend to emphasise only its epistemic disadvantages. In this paper, we argue that a satisfactory epistemic account of confabulation should also acknowledge those features which are (potentially) epistemically advantageous. For example, confabulation may allow subjects to exercise some control over their own cognitive life which is instrumental to the construction or preservation of their sense of self. (shrink)

During the last decades the question of defining life has gained increased interest but, at the same time, the difficulty in reaching consensus on a possible answer has led many to skeptical positions. This, in turn, has raised a wider debate about why defining life is so hard and controversial. Such a debate introduces additional aspects to be considered, like the role and nature of a definition of life itself. In this paper, we will focus on those aspects, arguing that (...) progress can be made if we conceive definitions of life as open heuristic tools that contribute to develop specific research strategies in the biological sciences and, more generally, to increase our understanding of life’s complexity. In contrast with pragmatic or operationalist approaches, we will defend that definitions of life comprise a set of ontological assumptions, together with an inherent unifying vocation, so they should be subject to comparison and critical assessment, closely related to the success or failure of the corresponding research programs, but also to the success or failure in establishing well-grounded interconnections among the latter. We consider that the search for a more coherent, integrated and generalized theory of biology cannot be pursued without keeping an empirical standpoint, and the exercise of defining life should not be taken as an obstacle but as a valuable instrument to achieve that goal.

The history of scientific illustrations is a story that correspond the cultural, economic, political and scientific history of the world. A look into the history of sciences displays that pictures and illustrations had a decisive role for the sciences progressive success and rising societal status from the sixteenth century. The illustrations visualized the unknown to graspable facts. Without the pictures the new discovered continents, the blood circulatory system and the body’s muscles had remained theoretical proclamations. The scientific discoveries became visible (...) and communicated, to a wider audience by its illustrations. The scientific illustrations and maps were intertwined with an epistemic ambition to unveil the true natural order. During the seventeenth century the concept of objectivity was interpreted as a quest for revealing nature’s ideal order, a task only feasible for the brilliant artist to accomplish. The epistemic ambition concurred with the belief that only one true ontological order existed that the scientific knowledge had to uncover. This concept of objectivity was succeeded by the modern concept of objectivity which equated objectivity with impartiality and elimination of the scientist’s subjective bias. The view from “nowhere” is still a valid, ruling definition of objectivity. However, the presence and huge expansion of computational pictures in the sciences as well in everyday life raises the question if a new sense of objectivity is framed. In physics and chemistry the produced pictures intend to be contributions to an ongoing theoretical discussion, about a nature in constant flux, let it be molecules or artificially processed materials in the nanoscale. The traveller designs her own map in advance, mixing the Google earth features with the personal arrangements. For both the scientists and the laymen the modernist objective virtues of detachment, impartiality and disinterestedness have been supplemented by a return of subjective involvements. (shrink)

This paper offers an epistemological discussion of self-validating belief systems and the recurrence of ?epistemic defense mechanisms? and ?immunizing strategies? across widely different domains of knowledge. We challenge the idea that typical ?weird? belief systems are inherently fragile, and we argue that, instead, they exhibit a surprising degree of resilience in the face of adverse evidence and criticism. Borrowing from the psychological research on belief perseverance, rationalization and motivated reasoning, we argue that the human mind is particularly susceptible to (...) belief systems that are structurally self-validating. On this cognitive-psychological basis, we construct an epidemiology of beliefs, arguing that the apparent convenience of escape clauses and other defensive ?tactics? used by believers may well derive not from conscious deliberation on their part, but from more subtle mechanisms of cultural selection.

The present work is motivated by two questions. (1) What should an intuitionistic epistemic logic look like? (2) How should one interpret the knowledge operator in a Kripke-model for it? In what follows we outline an answer to (2) and give a model-theoretic definition of the operator K. This will shed some light also on (1), since it turns out that K, defined as we do, fulfills the properties of a necessity operator for a normal modal logic. The interest (...) of our construction also lies in a better insight into the intuitionistic solution to Fitch's paradox, which is discussed in the third section. In particular we examine, in the light of our definition, De Vidi and Solomon's proposal of formulating the verification thesis as Φ → ¬¬KΦ. We show, as our main result, that this definition excapes the paradox, though it is validated only under restrictive conditions on the models. (shrink)

Philosophers and psychologists sometimes categorize emotions like surprise and curiosity as specifically epistemic. Is there some reasonably unified and interesting class of emotions here? If so, what unifies it? This paper proposes and defends an evaluative account of epistemic emotions: what it is to be an epistemic emotion is to have fittingness conditions that distinctively involve some epistemic evaluation. We argue that this view has significant advantages over alternative proposals and is a promising way to identify (...) a limited and interesting class of emotions. (shrink)

Psychologists say a measure has construct validity when it, in fact, measures the construct it is intended to measure. Construct validity is both an important notion in psychological research methods and the source of much confusion and debate among psychologists. I argue that this confusion arises, in part, because of a failure to distinguish between construct validity, a feature of measures relative to a construct, and construct legitimacy, a feature of the construct itself. I propose a prescriptive (...) account of construct validity on the basis of this distinction, then provide evidence for my account through two examples from research psychology. (shrink)

The meaning of the term ‘tarka’ is not clear in the modern literature on Classical Indian Philosophy. This paper will review different modern readings of this term and try to show that what the Nyāyasūtra and its classical commentaries called a ‘tarka’ should be understood as the following: a tarka is a cognitive act that validates a content (of a doubt or a cognition or a speech-act) by demonstrating its logical fitness or invalidates a content by demonstrating its logical unfitness. (...) A tarka can act as a metatheory too. Generating certainty is, according to the Classical Nyāya, a job assigned to an epistemic instrument ( pramāṇa ). It fails to do so when there arises a doubt regarding it. The moment a tarka dispels the doubt, the epistemic instrument generates certainty. Tarkas of different types will be exemplified by critically analyzing Gaṅgeśa’s applications of tarka in his magnum opus Tattvacintāmaṇi . These examples will clarify the definition of tarka formulated in this paper. (shrink)

One of the hallmark themes of Karl Popper’s approach to the social sciences was the insistence that when social scientists are members of the society they study, then they are liable to affect that society. In particular, they are liable to affect it in such a way that the claims they make lose their validity. “The interaction between the scientist’s pronouncements and social life almost invariably creates situations in which we have not only to consider the truth of such (...) pronouncements, but also their actual influence on future developments. The social scientist may be striving to find the truth; but, at the same time, he must always be exerting a definite influence upon society. The very fact that his pronouncements do exert an influence destroys their objectivity.” (Popper 1963. (shrink)

There is a prevailing opinion that conjectural knowledge (zann) cannot be taken as a basis in determining the fundamental theological principles among the theologians. However, from which sources and how to obtain certainty (yaqīn) and which types of knowledge are definitive (qat‘ī) have been discussed extensively. Certain and conjectural knowledge meet at a common point in terms of relying on evidence. Conjectural knowledge obtained via reasoning and/or religious scripture that do not express certainty. While conjectural knowledge has been essentially related (...) to the concepts of estimation, doubt, belief and knowledge, by its in term of value, it is stands closer to the concepts of knowledge and belief. Conjectural knowledge contains different degrees of certainty. When it is chosen to be more certain, it is considered as a valid conjecture, when it is disregarded, it is considered as erroneous conjecture. If there is no choice for its certainty, then it is called doubt (shakk). If the information/judgment obtained through reasoning becomes fixed, unchangeable and in a coherence that does not allow it to be otherwise, then it is called definitive (qat‘ī) knowledge. To achieve that, theologians generally used methods of argumentations like syllogism, induction, exhaustive investigation and disjunction (al-sabr wa’l-taqsīm) to provide such knowledge about divinity and prophethood. Theologians have used conjectural knowledge, which are based on endoxic (mashhūrāt), already granted (musallamāt) and acceptance of authority (maqbūlāt), in their dialectics to persuade their discussants, rather than to justify the fundamental theological issues of religion. While theologians mostly use rational proofs in theological issues, they also gave significant place to the scriptural narrative that determines the creed. In this context, theologians accepted the narrated evidence as binding and decisive, as long as it is certain in terms of both authenticity and implication. Ultimately, the fundamental theological principles of religion are based on these narrative evidences. Although the theologians do not accept single reports (khabar al-wahid) for their questionable authenticity, they also made inferences regarding subjects of traditions (sam‘iyyāt). Acting from this perspective, theologians tried to justify with narrative evidence rather than rational arguments on these issues such as torment in grave, intercession (shafā‘ah) and sirât, which are mostly matters of eschatology and the unseen (ghayb). Finally, it has been concluded that the conjectural knowledge is still valid in some secondary theological issues and the assumption that the conjectural knowledge has no deduction value in theology is not absolute.

Besides pure declarative arguments, whose premises and conclusions are declaratives, and pure imperative arguments, whose premises and conclusions are imperatives, there are mixed-premise arguments, whose premises include both imperatives and declaratives, and cross-species arguments, whose premises are declaratives and whose conclusions are imperatives or vice versa. I propose a general definition of argument validity: an argument is valid exactly if, necessarily, every fact that sustains its premises also sustains its conclusion, where a fact sustains an imperative exactly if it (...) favors the satisfaction over the violation proposition of the imperative, and a fact sustains a declarative exactly if, necessarily, the declarative is true if the fact exists. I argue that this definition yields as special cases the standard definition of validity for pure declarative arguments and my previously defended definition of validity for pure imperative arguments, and that it yields intuitively acceptable results for mixed-premise and cross-species arguments.

Side effects are a concern in medical decision making and a robust area of biomedical research. However, there is relatively little philosophical investigation into side effects as such, especially given that side effects are appealed to for various applications in philosophy of medicine. In addition, health authorities like the FDA, CDC, and WHO have contrary definitions of ‘side effect.’ Moreover, these definitions have clear counterexamples. This dissertation aims to provide a complete account of what side effects are. I (...) posit that an account of side effects ought to draw clean conceptual lines between side effects and related treatment outcomes. I contend that an account of side effects must address two components: the reasons behind an intervention that produced the side effect, and the causal powers of the intervention that brought about that effect. With this account in mind, I address contemporary philosophical models that distinguish placebo effects from side effects. These arguments, respectively in chapters 2 and 3, yield a more complete, less problematic account of side effects than previous accounts. The dissertation then turns to the process of discovering side effects, specifically in the post-market context. Given the paucity of external validity in pre-market drug trials, chapter 4 argues that post-market ‘phase IV’ trials blur the received distinction of ‘confirmatory’ versus ‘exploratory’ experimentation in philosophy of science. The other component of post-market drug research is spontaneous reporting, or the voluntary reporting of a suspected side effect to a regulatory body. Chapter 5 uses the framework of risks and values in science to examine why clinicians underreport, which hinders our ability to prevent drug-related harms. Chapter 6 looks at how patients could mitigate underreporting and develops a social-epistemic, pragmatic, and ethical framework which can evaluate proposals to engage patients to spontaneously report their suspected side effects. In short, this dissertation aims to firstly address the conceptual problems in how we define ‘side effect’ and relate it to other treatment outcomes, and secondly it addresses issues that hinder the scientific investigation of side effects.

Besides pure declarative arguments, whose premises and conclusions are declaratives (“you sinned shamelessly; so you sinned”), and pure imperative arguments, whose premises and conclusions are imperatives (“repent quickly; so repent”), there are mixed-premise arguments, whose premises include both imperatives and declaratives (“if you sinned, repent; you sinned; so repent”), and cross-species arguments, whose premises are declaratives and whose conclusions are imperatives (“you must repent; so repent”) or vice versa (“repent; so you can repent”). I propose a general definition of argument (...) validity: an argument is valid exactly if, necessarily, every fact that sustains its premises also sustains its conclusion, where a fact sustains an imperative exactly if it favors the satisfaction over the violation of the imperative, and a fact sustains a declarative exactly if, necessarily, the declarative is true if the fact exists. I argue that this definition yields as special cases the standard definition of validity for pure declarative arguments and my previously defended definition of validity for pure imperative arguments, and that it yields intuitively acceptable results for mixed-premise and cross-species arguments.

It is well-established that topos theory is inherently connected with intuitionistic logic. In recent times several works appeared concerning so-called complement-toposes, which are allegedly connected to the dual to intuitionistic logic. In this paper I present this new notion, some of the motivations for it, and some of its consequences. Then, I argue that, assuming equivalence of certain two definitions of a topos, the concept of a complement-classifier is, at least in general and within the conceptual framework of category (...) theory, not appropriately defined. For this purpose, I first analyze the standard notion of a subobject classifier, show its connection with the representability of the functor Sub via the Yoneda lemma, recall some other properties of the internal structure of a topos and, based on these, I critically comment on the notion of a complement-classifier.

Definitions I presented in a previous article as part of a semantic approach in epistemology assumed that the concept of derivability from standard logic held across all mathematical and scientific disciplines. The present article argues that this assumption is not true for quantum mechanics (QM) by showing that concepts of validity applicable to proofs in mathematics and in classical mechanics are inapplicable to proofs in QM. Because semantic epistemology must include this important theory, revision is necessary. The one (...) I propose also extends semantic epistemology beyond the ‘hard’ sciences. The article ends by presenting and then refuting some responses QM theorists might make to my arguments. (shrink)

Michael Devitt claims that the predicative material that constitutes complex referential expressions makes a semantic contribution to the proposition expressed. He thus deviates from direct referentialism, according to which every referential expression -either simple or complex- contributes just with an object to the proposition expressed, leaving the predicative material out of the semantic content. However, when dealing with misdescriptions, Devitt has suggested a pragmatic way out: the audience can understand what the speaker is referring to even if the object does (...) not fall under the corresponding description. From my perspective, this proposal questions the semantic validity of the predicative material, together with Devitt's original claim. In this paper, I propose a way to solve the problem posed by misdescriptions that appeals to the idea of epistemically relativized properties, according to which the properties ascribed to the object -by means of the predicative material- correspond to the way the speaker thinks of it and not to the way the object really is. Michael Devitt sostiene que el material predicativo que constituye las expresiones referenciales complejas hace un aporte semántico a la proposición expresada, alejándose así del referencialismo directo, para el cual toda expresión referencial -sea ésta simple o compleja- contribuye sólo con un objeto singular a la proposición expresada. Sin embargo, al enfrentarse al problema de las descripciones fallidas, Devitt ofrece una salida pragmática: el oyente comprende a qué se refiere el hablante aun cuando el objeto referido no caiga bajo la descripción utilizada. Esto pone en cuestión la validez semántica del material predicativo, desestimando la postura original de Devitt. En el trabajo propongo una solución a este problema, apelando a la idea de propiedades epistémicamente relativizadas, de acuerdo con la cual lo que se predica del objeto por medio del material predicativo corresponde a las creencias del hablante, y no a lo que el objeto realmente es.

This paper proposes an extended version of the interventionist account for causal inference in the practical context of biological mechanism research. This paper studies the details of biological mechanism researchers’ practices of assessing the evidential legitimacy of experimental data, arguing why quantity and variety are two important criteria for this assessment. Because of the nature of biological mechanism research, the epistemic values of these two criteria result from the independence both between the causation of data generation and the causation (...) in question and between different interventions, not techniques. The former independence ensures that the interventions in the causation in question are not affected by the causation that is responsible for data generation. The latter independence ensures the reliability of the final mechanisms not only in the empirical but also the formal aspects. This paper first explores how the researchers use quantity to check the effectiveness of interventions, where they at the same time determine the validity of the difference-making revealed by the results of interventions. Then, this paper draws a distinction between experimental interventions and experimental techniques, so that the reliability of mechanisms, as supported by the variety of evidence, can be safely ensured in the probabilistic sense. The latter process is where the researchers establish evidence of the mechanisms connecting the events of interest. By using case studies, this paper proposes to use ‘intervention’ as the fruitful connecting point of literature between evidence and mechanisms. (shrink)

In the philosophy of science, abstraction has usually been analyzed in terms of the interface between our experience and the design of our concepts. The often implicit assumption here is that such interface has a definite identifiable and universalizable structure, determining the epistemic correctness of any abstraction. Our claim is that, on the contrary, the epistemic grounding of abstraction should not be reduced to the structural norms of such interface but is also related to the constraints on the (...) cognitive processes of specific abstractions. This suggests that we should understand abstraction as embodied in different kinds of abstraction practices. (shrink)

This paper argues that Śrī Swāminārāyaṇ espoused a position on the pramāṇa-s (means of knowing), and his theory was that among these it is śabdapramāṇa that is the important and authoritative pramāṇa. However, in delineating the precise sources and textual authority that fall within the ambit of śabdapramāṇa, he privileged mostly the Smṛti texts, along with Vedānta and Bhagavadgītā commentaries, to which was added later his own Gujarati text Vachanāmrut, as canonical texts of the particular Sampradāya. In so doing, he (...) would be seen to be departing somewhat from classical positions on authoritative scriptures, in particular of Śaṅkara and, to an extent, Rāmānuja, for whom Śruti (‘revealed’) and Smṛti (‘recollected’) scriptures respectively denote quite different genre of texts, and with graded degree (rather kind) of authority; the former could even be apauruṣeya, authorless scriptures. The paper analyses the precise reasons for Swāminārāyaṇ arriving at this qualified position and the arguments he garnishes towards this doctrinal hermeneutic, concluding with comments on his slight departure from the classically accepted understanding of śabdapramāṇa where scriptural sources are the preeminent concern with a somewhat different epistemological trajectory.

A consequence relation is strongly classical if it has all the theorems and entailments of classical logic as well as the usual meta-rules (such as Conditional Proof). A consequence relation is weakly classical if it has all the theorems and entailments of classical logic but lacks the usual meta-rules. The most familiar example of a weakly classical consequence relation comes from a simple supervaluational approach to modelling vague language. This approach is formally equivalent to an account of logical consequence according (...) to which α1, ..., αn entails β just in case □α1, ..., □αn entails □β in the modal logic S5. This raises a natural question: If we start with a different underlying modal logic, can we generate a strongly classical logic? This paper explores this question. In particular, it discusses four related technical issues: (1) Which base modal logics generate strongly classical logics and which generate weakly classical logics? (2) Which base logics generate themselves? (3) How can we directly characterize the logic generated from a given base logic? (4) Given a logic that can be generated, which base logics generate it? The answers to these questions have philosophical interest. They can help us to determine whether there is a plausible supervaluational approach to modelling vague language that yields the usual meta-rules. They can also help us to determine the feasibility of other philosophical projects that rely on an analogous formalism, such as the project of defining logical consequence in terms of the preservation of an epistemic status.

Most modern definitions of art fail to successfully address the issue of the ever-changing nature of art, and rarely even attempt to provide an account that would be valid in more than just the modern Western context. This article develops a new theory that preserves the advantages of its predecessors, solves or avoids their problems, and has a scope wide enough to account for art of different times and cultures. It argues that an object is art in a given (...) context iff some person culturally competent in this context have afforded it the status of a candidate for appreciation for reasons considered good in this context. This weakly institutional view is supplemented by auxiliary definitions explaining the notions of cultural contexts, competence, and good reasons for affording the status. The relativisation to contexts brings increased explanatory power and scope, and the ability to account for the diversity of art. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Do You Mean, Rhetoric Is Epistemic?William D. HarpineIn 1967, Robert L. Scott (1967) advocated that "rhetoric is epistemic." This concept has enriched the work of rhetorical theorists and critics. Scott's essay is founded in a concept of argumentative justification in rhetoric, viewed as an alternative to analytic logic. Other writers, including Brummett (1976), Railsback (1983), and Cherwitz and Hikins (1986), have offered variations on Scott's theme. (...) The thesis that rhetoric is epistemic has been controversial, however, and from the tone of the debate one may draw two conclusions: many rhetorical theorists feel that Scott was on to something important, and the thesis as it has been developed is flawed. Much of the dispute centers on what the thesis means. These discussions have not yet adequately clarified that issue.The philosopher's most fundamental obligation is to define terms with care. It is in precisely this respect that the rhetoric-is-epistemic theorists have fallen short. Some of the key terms in this literature include rhetoric, knowledge, certainty, and truth. In too many cases, the writers on rhetorical epistemology have not defined their key terms at all. In other cases, their definitions are inadequate or inconsistent. This essay undertakes to sort out the most important definitional problems, which center on the rhetoric-is-epistemic theorists' habit of equivocating about the meanings of "rhetoric" and "certainty." The result makes it possible to endorse the validity of Scott's essentially ethical conclusions, while dismissing a number of unnecessary complexities in the arguments made by rhetoric-as-epistemic theorists. Finally, a few alternatives that might lead to more robust foundations for the rhetoric-as-epistemic thesis are suggested.In 1978, after reviewing four distinct interpretations of the claim that rhetoric is epistemic, Leff concluded that clarification of what that claim means "deserves more disciplined treatment than it has received in the recent literature" (1978, 77). The same could still be said. After some [End Page 335] thirty years of active research and speculation on the topic, one now sees fewer publications specifically advocating that rhetoric is epistemic. The distinguished rhetorical theorist Barry Brummett (1990) has declared the thesis deceased (69-72).All the same, textbook authors treat the thesis as a given, despite their tendency to interpret it in wildly different ways. Foss, for example, puts forward a view that "in the field of communication, the idea that rhetoric creates reality is known as the notion that rhetoric is epistemic, which simply means that rhetoric creates knowledge; epistemology is the study of the origin and nature of knowledge" (1989, 122; emphasis in the original). This version of the thesis, claiming that rhetoric actually "creates reality," might be more ontological than it is epistemic.1 Herrick takes a dialectical view that "through rhetorical interaction, people come to accept some ideas as true and to reject others as false. Thus, rhetoric's epistemic function in society can be seen in some ways to be a result of its benefit of testing ideas." Herrick continues that "once an idea has been tested thoroughly by a group, community, and society, it becomes part of what these groups take to be knowledge." Herrick contrasts this with the rejected view that "knowledge is all objective in nature and comes to us by way of direct experience or education" (1997, 22). Both Herrick and Foss offer interesting theses, and both attribute their views to Scott, but their views are obviously very different. There can be no surer evidence of the failure to use terms precisely.Brummett (1990) attributes the demise of rhetoric-is-epistemic research to the failure of critics to employ the idea in rhetorical criticism. Brummett might be right to the extent that much of the rhetoric-is-epistemic literature is indeed exceptionally abstract. Specific discussions might clarify some issues. Nonetheless, some notable rhetorical critics have indeed employed a concept that rhetoric is epistemic (e.g., Scott and Klumpp 1984; Sullivan 1992). The issues remain unclear. Furthermore, rhetorical criticism per se cannot clarify the meanings of theoretical terms. More likely, one sees less and less published research about the thesis that rhetoric is epistemic precisely because the thesis has not been laid out clearly... (shrink)

The aim of this paper is to investigate the consequences of the bibliometrics-based evaluation system of scientific production on the contents and methods of sciences. The research has been conducted by means of in-depth interviews to a multi-disciplinary panel of Italian researchers. We discuss the implications of bibliometrics-based evaluation on the choice of the research topic, on the experimental practices, on the dissemination habits. We observe that the validation of the bibliometrics-based evaluation practices relies on the acceptance and diffusion within (...) the scientific community, and that these practices are self-sustained through their wide application. We discuss possible evolving scenarios, also considering the recent development of digital archives. (shrink)

The age-old question “What is truth?” is not an unambiguous one. There are at least two different meanings. In one sense, it is a semantic question about the meaning of the word “truth” and/or a metaphysical question about the nature of the property of truth, that is, how truth can be defined in terms of other notions, if it is definable at all. In another sense, it is an epistemological question about the criterion or test of truth, that is, how (...) we can recognize or accept (empirical) propositions as true. Ayer, in Language, Truth and Logic (LTL) and some other articles, tried to convince us that when we attempt to elucidate a theory of truth, we are only engaging in the epistemological project of finding the criterion of truth. This anti-semantical and anti-metaphysical view is based on Ayer’s (radical) deflationism about truth. In this chapter, I will argue that since Ayer did not accept that the criterion of truth is intimately related to the concept of truth, he can be seen as a deflationist about the nature of truth and as an advocate of a certain (Schlickian) kind of correspondence conception about the criterion of truth. His position would not be tenable if he had maintained what some of his contemporaries accepted, namely that there is a close connection between the two truth-theoretical tasks: the definitional and the criterial one.

In this article, we argue that John Henry Newman was right to think that our passional nature can play a legitimate epistemic role. First, we unpack the standard objection to Newman’s understanding of the relationship between our passional nature and the evidential basis of faith. Second, we argue that the standard objection to Newman operates with a narrow definition of evidence. After challenging this notion, we then offer a broader and more humane understanding of evidence. Third, we survey recent (...) scholarship arguing that emotions, a key aspect of our passional nature, are cognitive. In this light, they plausibly have a proper epistemic role. Fourth, we defend Newman’s reliance on the passional nature in epistemic matters by showing how reasonable it is in light of this recent work on evidence and the nature of emotions. Newman’s insistence that the formation of a right state of heart and mind is crucial for epistemic success is far from untenable. (shrink)

The attempt to define life has gained new momentum in the wake of novel fields such as synthetic biology, astrobiology, and artificial life. In a series of articles, Cleland, Chyba, and Machery claim that definitions of life seek to provide necessary and sufficient conditions for applying the concept of life—something that such definitions cannot, and should not do. We argue that this criticism is largely unwarranted. Cleland, Chyba, and Machery approach definitions of life as classifying devices, thereby (...) neglecting their other epistemic roles. We identify within the discussions of the nature and origin of life three other types of definitions: theoretical, transdisciplinary, and diagnostic definitions. The primary aim of these definitions is not to distinguish life from nonlife, although they can also be used for classificatory purposes. We focus on the definitions of life within the budding field of astrobiology, paying particular attention to transdisciplinary definitions, and diagnostic definitions in the search for biosignatures from other planets.

The latest edition of the Diagnostic and Statistical Manual of Mental Disorders included the Social Communication Disorder as a new mental disorder characterized by deficits in pragmatic abilities. Although the introduction of SPCD in the psychiatry nosography depended on a variety of reasons—including bridging a nosological gap in the macro-category of Communication Disorders—in the last few years researchers have identified major issues in such revision. For instance, the symptomatology of SPCD is notably close to that of Autism Spectrum Disorder. This (...) opens up the possibility that individuals with very similar symptoms can be diagnosed differently and receive different clinical treatments and social support. The aim of this paper is to review recent debates on SPCD, particularly as regards its independence from ASD. In the first part, we outline the major aspects of the DSM-5 nosological revision involving ASD and SPCD. In the second part, we focus on the validity and reliability of SPCD. First, we analyze literature on three potential validators of SPCD, i.e., etiology, response to treatment, and measurability. Then, we turn to reliability issues connected with the introduction of the grandfather clause and the use of the concepts of spectrum and threshold in the definition of ASD. In the conclusion, we evaluate whether SPCD could play any role in contemporary psychiatry other than that of an independent mental disorder and discuss the role that non-epistemic factors could play in the delineation of the future psychiatry nosography.

Over the last three decades, joint action has received various definitions, which for all their differences share many features. However, they cannot fit some perplexing cases of weak joint action, such as demonstrations, where agents rely on distinct epistemic sources, and as a result, have no first-hand knowledge about each other. I argue that one major reason why the definition of such collective actions is akin to the classical ones is that it crucially relies on the concept of (...) common knowledge. To this end, I first argue for the necessity of common knowledge for joint action in general due to the increased reliability of success it entails. I then defend the relevance of common knowledge against several criticisms, point at an adequate weakening, and discuss alternative approaches. Although structurally weaker, the common knowledge has a richer content in weak joint actions. As a result, even if the links between individuals are seriously stretched, much is still shared among them. Weak joint actions still require considerable cognitive abilities indeed. (shrink)

The central argument in the Euthyphro is the one Socrates advances against the definition of piety as "what all the gods love." The argument turns on establishing that a loved thing (philoumenon) is 1) a loved thing because it is loved (phileitai), not 2) loved because it is a loved thing. I suggest that this claim can be understood and found acceptable if we take "because" to be used equivocally in it. Despite the equivocation, Socrates' argument is valid, showing that (...) Euthyphro cannot offer this definition consistently with his view that the gods have as a reason for loving pious things that they are pious things. (shrink)

We propose that, for the purpose of studying theoretical properties of the knowledge of an agent with Artificial General Intelligence (that is, the knowledge of an AGI), a pragmatic way to define such an agent’s knowledge (restricted to the language of Epistemic Arithmetic, or EA) is as follows. We declare an AGI to know an EA-statement φ if and only if that AGI would include φ in the resulting enumeration if that AGI were commanded: “Enumerate all the EA-sentences which (...) you know.” This definition is non-circular because an AGI, being capable of practical English communication, is capable of understanding the everyday English word “know” independently of how any philosopher formally defines knowledge; we elaborate further on the non-circularity of this circular-looking definition. This elegantly solves the problem that different AGIs may have different internal knowledge definitions and yet we want to study knowledge of AGIs in general, without having to study different AGIs separately just because they have separate internal knowledge definitions. Finally, we suggest how this definition of AGI knowledge can be used as a bridge which could allow the AGI research community to import certain abstract results about mechanical knowing agents from mathematical logic.

The study proposes a new approach towards a social phenomenon called convention and submits a minimalistic definition of convention, which provides a promising basis for future analysis unburdened by contra-Lewisian objections. The definition itself, based on the insights of Ruth Millikan in the study Language Conventions Made Simple, represents a simple and efficient means of delimiting essential components of conventional behaviour (stripped of most of the controversial issues from previous debates on Lewis’s notion) solely by means of the role of (...) precedent and its ability to reproduce. Yet, it is argued that a few additional conditions are required for a valid and distinct notion of conventionality: namely, the inclusion of a coordination aspect and an extension of the concept of precedent. The final version of the definition, thereafter, meets intuitive requirements of conventionality (e.g., arbitrariness) and has the generality to embrace different types of conventions. (shrink)

This paper evaluates whether and to what extent modal constraints on knowledge or the semantics of ‘knows’, which make essential reference to what goes on in other possible worlds, can be considered non-epistemic factors with epistemic significance. This is best understood as the question whether modal factors are non-truth-relevant factors that make the difference between true belief and knowledge, or to whether a true belief falls under the extension of ‘knowledge’ in a context, where a factor is truth-relevant (...) with respect to S’s belief that P iff it bears on the probability that P is true. To the extent that these factors are non-epistemic, epistemologies that endorse them—modal epistemologies—stand in conflict with intellectualism. I focus on three modal epistemologies: safety, sensitivity, and David Lewis’s epistemic contextualism. I argue that prima facie, safety and sensitivity allow that non-epistemic changes in a context can shift the closeness ordering on worlds, and in so doing make a difference to whether S knows P, while Lewis’s contextualism allows that non-epistemic changes in a context can shift the relevant domain of not-P possibilities that must be eliminated for ‘S knows P’ to be true in that context. Then to make her theory compatible with intellectualism, the modal epistemologist must say much more about the notion of probability at play in the definition of ‘truth-relevant’. I suggest that either accepting or rejecting that modal epistemologies are intellectualist has significance consequences for debates between pragmatists and purists, which radiate into wider contemporary epistemology.

Despite the undeniable epistemic progress of developmental biology from the second half of the twentieth century to the present day, there still is widespread disagreement on defining the biological term of ‘development’. This scientific field epistemologically is neither unsuccessful nor immature, thus the persistent lack of agreement on its most central concept raises some important questions: is there any need for an explicit definition of biological development, and if so, what content should the definition have? My central thesis is (...) twofold. First, that current definitions of biological development are conceptually or empirically inadequate. Second, that an explicit definition of biological development is very much needed (a) for the practical purposes of science textbooks, but more importantly is needed (b) epistemically for exposing or overcoming problematic assumptions and for partially guiding scientific research by coding the appropriate assumptions. To support this thesis, initially I will show the deficiencies of the dominant definitions of biological development; and subsequently I will provide two arguments: an Argument from Practical Purposes and an Argument from Epistemic Purposes. Finally, for accommodating practical and epistemic purposes and as a response to the inadequacy of the available definitions of development, I will propose and defend an operational definition of biological development which is aimed to be broader than the received ones, while being more precise and fruitful to conduct empirical research.

I argue that, in order for us to be justified in believing that two theories are metaphysically equivalent, we must be able to conceive of them as unified into a single theory, which says nothing over and above either of them. I propose one natural way of precisifying this condition, and show that the quantifier variantist cannot meet it. I suggest that the quantifier variantist cannot meet the more general condition either, and argue that this gives the metaphysical realist a (...) way to rule out theses like quantifier variance without appealing to fundamentality, grounding, or "levels" of reality.

The aim of this paper is twofold. First, I want to re-examine the epistemic status of elaborated delusions. Bortolotti (2016, 2020) claims that they can be epistemically innocent. However, I will show that this type of delusions is more unique than suggested by the existing analyses of their epistemic status. They typically cause more profound harms than other kinds of delusions, and in most cases, it would be counterproductive to classify them as epistemically beneficial or innocent. I will (...) employ predictive and phenomenological models of delusions and the enactivist notion of sensus communis to explain the harms and possible benefits of elaborated delusions and why I think the existing definition does not fully grasp them. Based on this analysis, I will propose changes to the conditions for epistemic innocence. (shrink)

This paper takes stock of all the various factors that cause the design-time opacity of autonomous systems behaviour. The factors include embodiment effects, design-time knowledge gap, human factors, emergent behaviour and tacit knowledge. This situation is contrasted with the usual representation of moral dilemmas that assume perfect information. Since perfect information is not achievable, the traditional moral dilemma representations are not valid and the whole problem of ethical autonomous systems design proves to be way more empirical than previously understood.

A critical commentary on the article “The Epistemic Harms of Empathy in Phenomenological Psychopathology” by Lucienne Spencer and Matthew Broome (2023) is presented. The authors committed the “fallacy of ambiguous or vague definition” by incorrectly interpreting Karl Jaspers’ conceptualizations, resulting in difficulties following logical arguments and arriving at reasonable conclusions. To overcome this fallacy, the commentary provides conceptual clarifications regarding Jaspers’ empathic understanding (einfühlendes Verstehen), conceived as the foundational concept of his project to develop a phenomenologically oriented psychopathology. Jaspers (...) initially introduced this concept in the article “Die phänomenologische Forschungsrichtung in der Psychopathologie” [The Phenomenological Research Direction in Psychopathology], published in 1912, and extended in his magnum opus “Allgemeine Psychopathologie” [General Psychopathology], published in 1913.

Both clinical research and basic science rely on the epistemic practice of extrapolation from surrogate models, to the point that explanatory accounts presented in review papers and biology textbooks are in fact composite pictures reconstituted from data gathered in a variety of distinct experimental setups. This raises two new challenges to previously proposed mechanistic-similarity solutions to the problem of extrapolation: one pertaining to the absence of mechanistic knowledge in the early stages of research and the second to the large (...) number of extrapolations underpinning explanatory accounts. An analysis of the strategies deployed in experimental research supports the conclusion that while results from validated surrogate models are treated as a legitimate line of evidence supporting claims about target systems, the overall structure of research projects also demonstrates that extrapolative inferences are not considered definitive or sufficient evidence, but only partially justified hypotheses subjected to further testing. 1 Introduction2 Surrogate Models2.1 What exactly is a surrogate model?2.2 Why use surrogate models?3 Prior Validation of Surrogate Models3.1 The validation and ranking of surrogate models in the early stages of basic research3.2 The validation of surrogate models in later stages of basic research and in clinical research4 ‘Big Picture’ Accounts and the Extrapolations Underpinning Them4.1 The mosaic nature of mechanistic descriptions in basic science4.2 Challenges for mechanistic-similarity-based validation protocols5 Retrospective Testing of Extrapolated Knowledge5.1 Holistic confirmation5.2 Fallback strategies6 Conclusions.
