In this dissertation, I explore the distinction between reason (ratio) and intuitive knowledge (scientia intuitiva) in Spinoza’s Ethics in order to explain the superior affective power of the latter over the former. In addressing this fundamental but relatively unexplored issue in Spinoza scholarship, I suggest that these two kinds of adequate knowledge differ not only in terms of their method, but also with respect to their content. I hold that unlike reason, which is a universal knowledge, (...) intuitive knowledge descends to a level of particularity, including the adequate knowledge of one’s own essence as it follows directly from God, which is a superior form of self-knowledge. Since, for Spinoza, there is an intrinsic relationship between the pursuit of knowledge and how we live our lives, my interpretation of these two ways of knowing is that they are at the same time two ways of living.

L'analisi dell'aristotelismo «platonizzante» nell'ambito della filosofia araba prima della sistemazione della Shifa di Avicenna, secondo cui Dio non avrebbe conoscenza dei particolari, consente all'A. di dimostrare come ci siano stati anche approcci platonici ad Aristotele , che non sono passati attraverso il filtro dei neoplatonici greci. L'altra cosa significativa è il fatto che all'interno della scuola di Baghdad vi sono modi diversi di intendere lo stato ontologico degli universali. L'A. tenta anche di ridimensionare la figura di al-Farabi all'interno della scuola (...) di Baghdad. I filosofi considerati sono al-Farabi, Yahya b. Adi e Ibn al-Tayyib. (shrink)

As one commentator notes, Spinoza’s conception of “the third kind of knowledge”—intuition, has been “regarded as exceptionally obscure. Some writers regard it as a kind of mystic vision; others regard it as simply unintelligible.” For Spinoza, the first kind of knowledge, which he calls “imagination,” is a kind of sense-experience of particulars; the second kind, which he calls “understanding,” involves the rational grasp of universals, and the third, in his words, “proceeds from an adequate idea of the (...) formal essence of some of the attributes of God to an adequate knowledge of the essence of things.” In this essay I will attempt to show, through an explication of Spinoza’s concept of intuition, how a prime example of intuition can be found in the art of poetry. More specifically, I will examine resonances between the work of the poet Gerard Manley Hopkins (1844–1889) and Baruch de Spinoza (1632–1677) by exploring the ways in which Hopkins’ poetry can work as both (1) an exemplar of poetry qua Spinozistic intuition, and (2) an intuition-based access to Spinoza’s thought. The upshot of this essay, then, is that there is a kind of knowledge, and by implication a kind of education (through which to acquire that knowledge) which—even for a philosopher as mathematically rigorous as Spinoza—may require recourse to the art of poetry.

Could a computer be programmed to make moral judgments about cases of intentional harm and unreasonable risk that match those judgments people already make intuitively? If the human moral sense is an unconscious computational mechanism of some sort, as many cognitive scientists have suggested, then the answer should be yes. So too if the search for reflective equilibrium is a sound enterprise, since achieving this state of affairs requires demarcating a set of considered judgments, stating them as explanandum sentences, and (...) formulating a set of algorithms from which they can be derived. The same is true for theories that emphasize the role of emotions or heuristics in moral cognition, since they ultimately depend on intuitive appraisals of the stimulus that accomplish essentially the same tasks. Drawing on deontic logic, action theory, moral philosophy, and the common law of tort, particularly Terry's five-variable calculus of risk, I outline a formal model of moral grammar and intuitive jurisprudence along the foregoing lines, which defines the abstract properties of the relevant mapping and demonstrates their descriptive adequacy with respect to a range of common moral intuitions, which experimental studies have suggested may be universal or nearly so. Framing effects, protected values, and implications for the neuroscience of moral intuition are also discussed. (shrink)

The discussion of universals in Peter Abelard’s Logica ‘Ingredientibus’ has been interpreted in many ways. Of particular controversy has been the proper way to interpret his use of the term status. In this paper I offer an interpretation of status by comparing Abelard’s account of knowledge of universals to Edmund Husserl’s presentations of categorial and eidetic intuition. I argue that status is meant to be understood as something like an ideal object, in Husserl’s sense of the term. (...) First, I present Abelard’s discussion of status and distinguish this term from universals, things, acts of understanding, and forms. Next, I consider Husserl’s account of categorial and eidetic intuition. Finally, I draw parallels between the two while showing how an interpretation of status as ideal object overcomesthe interpretive problems encountered by other commentators on Abelard. (shrink)

A reanalysis of Atran's data is presented in which the comparison between Itzaj and Michigan animal names is represented in spatial rather than taxonomic form. Similarity among all subjects is also represented in spatial terms. Finally, culturally shared knowledge between the two cultures is shown to be about ten times larger than the culture-specific component unique to each culture.

Basing itself on the cognitive theory of the modern Canadian philosopher and theologian Bernard Lonergan, the article conducts a critical appraisal of the notion of intuitive knowledge (ḥads in Arabic) as espoused by the famous medieval Islamic philosopher Ibn Sīnā (Avicenna). The article shows the ways in which Lonergan’s crucial distinction between the objectivity as the knower’s intelligent grasp of the real and the objectivity as the knower’s critical affirmation of the real, revises the epistemological primacy of intuitivism (...) that is endemic not only to Avicennian thought in particular but also to Aristotelian tradition generally. At the same time, it shows various elements of continuity between Lonergan’s and Avicenna’s analyses of intentional consciousness. It argues that, while Lonergan’s thought revises Avicenna’s lack of attention to the role of one’s further rational affirmation of anything that one has gasped only intuitively, Lonergan’s cognitive theory might conceptually benefit from a number of original Avicennian insights when it comes to one’s experiential and intelligent grasp of the objects of one’s consciousness.

After decades of being met with suspicion or even disdain the epistemic role of intuitions – and specifically the school of ethical intuitionism – has seen a revival. This revival has been undertaken by both leading moral philosophers such as Jonathan Dancy and Robert Audi and moral psychologists like Jonathan Haidt and Joshua Greene.See Jonathan Dancy, Ethics Without Principles (Oxford: Oxford University Press, 2004), Robert Audi, The Good in the Right. A Theory of Intuition and Intrinsic Value (Princeton: Princeton University (...) Press, 2003) and Joshua D. Greene and Jonathan Haidt, “How (and Where) Does Moral Judgment Work?,” Trends in Cognitive Sciences 6 (2002): 517–523.Dancy, for example, has argued that moral principles play no substantive role in moral thought and judgement. Since it has traditionally been assumed that our particular moral judgements are justified on the basis of the more general moral principles from which they are derived, Dancy’s moral epistemology takes a diffe.

John Locke is the greatest English philosopher. _An Essay Concerning Human Understanding_, one of the most influential books in the history of thought, is his greatest work. In this study the historical meaning and philosophical significance of Locke's _Essay_ are investigated more comprehensively than ever before. _Locke_ was originally published in two volumes, _Epistemology_ and _Ontology_. This paperback edition has within its covers the full text of both volumes.

The article proposes a new solution to the long-standing problem of the universality of essences in Spinoza's ontology.

This account provides the best fit both with the textual evidence and with Spinoza's other metaphysical and epistemological commitments.

The compass we use to navigate life needs to be cultivated from an early age. My sense is that the arts, including Plato’s dialogues cultivate our navigational sense. It does not tell us rationally what is good or what is bad. It is not that simple. Remember, the stars we sail by, are not fixed, either. So we need to develop a sense for what may be right or not in any particular situation. We may have a general sense, but (...) need to learn how to apply this general sense to specific situations, which are unique. In every new situation we have to figure out what is the right thing to do. And this may be different for different people as well. Too often we look for a one-fits-all solution, including our moral sense of right and wrong. And this is where we so often end up resorting to a violent “solution,” just to end it all. While we may have acquired so many technological advancements in our modern world, on the level of understanding how to navigate the world we may have regressed even, now that we can increasingly rely of highly technically advanced weapons. Again, violence seems to bear the only “solution.” -/- Yet, with our compass intact, we might be better able to recognize the red flags when we see them in real life and not find ways to rationalize, justify or ignore the reality right before our eyes. When we recognize them early, they can be handled so much easier and better. Molehills are less difficult than mountains. And to get rid of a mountain, you may just have to blow it up, using violence... (shrink)

In this thesis, I examine the perceptibility of the Platonic Ideas in the thought of Arthur Schopenhauer. The work is divided into four chapters, each focusing and building upon a specific aspect related to this question. The first chapter (“"Plato and the Primacy of Intellect"”) deals with Schopenhauer’s interpretation specific to Platonic thought. I there address the question of why it is that Schopenhauer should consider Plato to have interpreted the Ideas as 'perceptible', particularly in view of evidence which seems (...) to testify to the contrary. Does Schopenhauer misinterpret Plato, or are there sufficient grounds for considering his interpretation consistent? This is important in light of Schopenhauer’s reinterpretation of the Platonic Idea on the basis of the primacy of the will in contradistinction to Plato’'s own emphasis upon the intelligible. In effect, for Schopenhauer, Plato confuses the nature of imperceptible concepts with the more perceptually grounded Ideas. In the second chapter (“"On the Direct Path to Knowledge"”), I explore Schopenhauer’'s methodological approach on the basis of the will. I there discuss the difference between Schopenhauer and Kant with respect to Transcendental Idealism, particularly in terms of their separate analysis and derivation of the thing-in-itself. From there, I turn to a consideration of Schopenhauer'’s discussion of the nature of formal and empirical intuitions, of abstraction and the nature of universal concepts, and finally of the intuitively grounded nature of mathematical demonstration which serves as an analogy for the manner in which Schopenhauer deals with knowledge of the Ideas. In the third chapter ("“The Perceptibility of the Ideas”"), I discuss the manner in which the Ideas become accessible as the manifestation of the Will, arising through the representation of perception. There a number of distinctions are made between Ideas and concepts, as well as the nature of contemplation through Genius. The Ideas are found to be perceptible as aesthetic intuitions which relate not only to the in-itself nature inherent to phenomena, but serve also as the essential basis and foundation for all genuine forms of art. In the fourth and final chapter (“"Critical Discussion of Schopenhauer’s Ideas"”), I consider and outline a number of potential problems with respect to Schopenhauer’s analysis. In particular, Schopenhauer encounters difficulties on the basis of the simultaneous immanence and transcendence of the Ideas; of the knowledge of the Ideas characterized as intuitive while yet having a strangely abstract basis; of the unity of the will in face of the plurality of Ideas and phenomena; and finally of the annihilation of the will which creates essential problems in terms of the desideratum of knowledge itself. I here also attempt to offer various solutions to these problems where relevant. The conclusion which I arrive at in this work is that any radical reorientation of ontology must bear an essential effect upon the character and methodology of knowledge itself. In other words, Schopenhauer’s interpretation of the perceptibility of the Ideas is a direct consequence of hi s analysis of the will as the metaphysical thing-in-itself. In fact, this essential change colors his entire epistemological approach, from science and mathematics, to logic and the Ideas—from the ground the up. (shrink)

The problem of universals versus particulars is central to the paradox of historical knowledge. History interpreted in terms of a closed set of universals denies qualitative change; history interpreted in terms of unique events allows no support for generalizations. Three approaches to this problem are: rationalist, intuitive, and philosophic history. Rationalist and intuitive history are unsatisfactory. Rationalist history is deterministic, reducing experiences to strictly defined universals. Intuitive history, stressing the particular, is subjective. To (...) overcome this dilemma, philosophic history would have to develop a notion of universals stable enough to sustain order and flexible enough to allow for real change. Such a notion can be found in the manner in which entities are created through metaphoric conflation. (shrink)

We found a direct relationship between variation in informants' grammaticality intuitions about pronoun coreference and variation in the same informants' use of a clause segmentation strategy during sentence perception. It has been proproposed that ‘c‐command’, a structural principle defined in terms of constituent dominance relations, constrains within‐sentence coreference between pronouns and noun antecedents. The relative height of the pronoun and the noun in the phrase structure hierarchy determines whether the c‐command constraint blocks coreference: Coreference is allowed only when the complement (...) structure containing the noun is attached higher than the pronoun. We collected informants' judgments on pronoun‐noun coreference in which the noun antecedent was contained in a complement structure dominated by either the Sentence‐node (S‐node) (higher than the pronoun) or the Verb‐phrase‐node (VP‐node) (not higher than the pronoun). We also assessed each informant's perceptual clause‐closure tendency using an auditory word‐monitor paradigm. Informants who strongly segmented clauses in the perceptual task did not differentiate between an S‐ and VP‐attachment of sentence complements, as revealed in their coreference judgments, but rather appeared to attach all sentence complements to the S‐node. Informants with relatively weak perceptual segmentation differentiated their coreference judgments according to the node attachment of the complement structure. These results indicate that the linguistic universal controlling within‐sentence coreference applies to the perceptually available structure for a sequence, not to its pure linguistic structure. Hence, linguistic intuitions result from the interaction of three independent faculties: language‐specific knowledge, perceptual processes, and linguistic universals. (shrink)

: While thought experiments play an important role in contemporary analytic philosophy, much remains unclear about thought experiments. In particular, it is still unclear whether the judgments elicited by thought experiments can provide evidence for the premises of philosophical arguments. This article argues that, if an influential and promising view about the nature of the judgments elicited by thought experiments is correct, then many thought experiments in philosophy fail to provide any evidence for the premises of philosophical arguments.

The article argues that universals of law, i.e. the laws of nature, are the general axioms of a deductive system of all knowledge, and their deductive consequences. Universals of fact are generalisations deducible from these together with particular facts.

Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is demonstrated through (...) analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine’s epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi’s theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine. (shrink)

This thesis attempts to argue against an influential interpretation of Kant's philosophy of mathematics according to which the role of pure intuition is primarily logical. Kant's appeal to pure intuition, and consequently his belief in the synthetic character of mathematics, is, on this view, a result of the limitations of the logical resources available in his time. In contrast to this, a reading is presented of the development of Kant's philosophy of mathematics which emphasises a much richer philosophical role for (...) intuition, beyond that of filling in deductive gaps in mathematical arguments. This role is largely determined by two factors: on the one hand, the epistemological gap in a traditional account of mathematical certainty, and on the other hand, the metaphysical worry raised by the followers of Leibniz and Wolff regarding the status of mathematics as a science consisting of truths. ;By appreciating how Kant's philosophy of mathematics developed against the background of what he saw as a conflict between the 'metaphysicians' and the 'mathematicians', we can see how the doctrine of pure intuition was required to fill the gaps in the account of the method and certainty of mathematics which Kant presents in the Prize Essay of 1764. This conflict takes its sharpest form between the monadists who uphold the metaphysical necessity of simple elements, and the geometers who uphold the infinite divisibility of space. In the Prize Essay Kant indirectly addresses this conflict by comparing the two disciplines. He asserts that the method of attaining certainty in mathematics is different from the method of metaphysics, and that as a result of this difference--primarily the different roles of definitions in each--mathematics is capable of a higher degree of certainty than metaphysics. He does not, however, explain this difference. Such an explanation seems particularly important in light of Kant's wish to secure geometry against the challenge of metaphysics. This thesis attempts to show that it is to provide such an explanation, to provide a philosophical grounding for the Prize Essay account, that Kant invokes the doctrine of pure intuition in his later account of mathematical knowledge.

Russell’s distinction between knowledge by acquaintance and knowledge by description has been recently re-examined in frequently controversial epistemo-logical contributions. The present essay reflects upon the pertinent papers by D. F. Pears, J. Hintikka, R. Chisholm, W. Sellars, A. J. Ayer, and others, but is pri-marily founded on Russell’s significant formulations from his writings published between 1910 and 1918. By employing an auxiliary device of a late-Wittgen-steinian language game, I explore at first the situation in which human subject is (...) “experiencing” and naming particular objects and later the subject’s acquaintance with universals. The reconstruction of such situations shows that, contrary to Russell’s assumptions, even the “purest” acquaintance cannot function without knowledge by description, i.e. without sta-ting propositions about the object of acquaintance . Then the only “descriptionless” alternative would be a kind of intuitive knowledge of such objects which is difficult to reconcile with the position held by Russell in the 1910s. Whatever the consequences, this topic retains its fundamental epistemological significance. (shrink)

Modal intuitions are not only the primary source of modal knowledge but also the primary source of modal error. An explanation of how modal error arises — and, in particular, how erroneous modal intuitions arise — is an essential part of a comprehensive theory of knowledge and evidence. This chapter begins with a summary of certain preliminaries: the phenomenology of intuitions, their fallibility, the nature of concept-understanding and its relationship to the reliability of intuitions, and so forth. It (...) then identifies two sources of modal error: the first has to do with the failure to distinguish between metaphysical possibility and various kinds of epistemic possibility; the second, with the local misunderstanding of one's concepts. The first source of error is widely misunderstood; the second source has not been discussed in philosophical literature. This source of modal error, and the potential to overcome it, has wide-ranging implications for philosophical method. The failure to understand these sources of modal error has recently led to sceptical accounts of intuition and modal error, which are, ultimately self-defeating. (shrink)

Most of the recent work in chaos theory has been the development of data analysis tools for analyzing chaotic data. It is based upon the results of the application of these tools that many researchers have made claims that such phenomena as heartbeats, planetary orbits, and chemical reactions are chaotic. ;The first part of my dissertation is concerned with investigating the standard methods that are used to determine whether a system is chaotic, and the requirements of these methods. I begin (...) by explaining chaos theory, and providing a generally accepted definition of chaos. I then explain the current methods that have been developed for experimentally studying chaotic systems. With this in mind, I turn to a more theoretical investigation of the reliability of these methods. Within the framework of formal learning theory, I discuss the conditions under which a scientist can reliably determine whether a system is chaotic. ;Generalizing this problem leads to the philosophical center of my dissertation: an investigation that relates how the conceptions of reliability of the scientists who work with chaos theory fit into a larger philosophical picture of reliable knowledge, and whether and in what sense or senses scientists are justified in their beliefs that particular systems are chaotic. ;I argue that Alvin Goldman is correct in a general sense; cashing out "justified" as "produced by a process that reliably produces true beliefs" captures a very strong intuition about knowledge and justification. I also argue that defining reliability, as Goldman does, in terms of "truth-ratios" does not capture our intuitions about reliability, and is often ill-defined. Instead, we need to define a reliable process as one which does one of two things: either the process always produces true beliefs, or the process gives specific conditions under which it will fail to produce true beliefs. ;Finally, I return to the discussion of a particular instance of scientific knowledge, the knowledge that a system is chaotic. I argue that, under my conception of reliabilism, and under certain conditions, scientists are in fact justified in their beliefs that particular dynamical systems in nature are chaotic. (shrink)

Should citizens have equal say regarding the running of society? Following the principles of democracy, and most of political philosophy: yes (at least at a fundamental level, thus allowing for representatives and the like). Indeed, comparing the main alternative seemingly supports this intuition. Epistocracy would instead give power just to the most epistemically competent. Yet testing citizens’ political and economic knowledge looks apt to disproportionately disempower marginalised groups, making the position seem like a nonstarter and democracy the clear winner. (...) Nevertheless, this paper argues against giving citizens equal say, or at least, it offers the strongest possible motivation for this position. In particular, I introduce the progressive case for epistocracy, and what I term standpoint epistocracy. This account refigures the relevant notion of political competence such that it is not the most privileged classes who would most likely constitute our epistocracy, but rather, the least. The resulting picture considerably improves on traditional versions of epistocracy and also democracy. (shrink)

The idea of dignity seems indissociable from that of humanity, whether in its universal dimension of ‘human dignity’, or in the individual ‘dignity of the person’. This paper provides an outlook on the ethics governing the sciences and technology, in particular the biological sciences and biotechnology, and recalls the notion of ‘glory’, both human and divine, as it infuses a great part of the Middle Ages and the Renaissance cultures, just before the scientific revolution in Europe.

The world contains objective causal relations and universals, both of which are intimately connected. If these claims are true, they must have far-reaching consequences, breathing new life into the theory of empirical knowledge and reinforcing epistemological realism. Without causes and universals, Professor Fales argues, realism is defeated, and idealism or scepticism wins. Fales begins with a detailed analysis of David Hume's argument that we have no direct experience of necessary connections between events, concluding that Hume was mistaken (...) on this fundamental point. Then, adopting the view of Armstrong and others that causation is grounded in a second-order relation between universals, he explores a range of topics for which the resulting analysis of causation has systematic implications. In particular, causal identity conditions for physical universals are proposed, which generate a new argument for Platonism. The nature of space and time is discussed, with arguments against backward causation and for the view that space and time can exist independently of matter or causal process. Many of Professor Fales's conclusions seem to run counter to received opinion among contemporary empiricists. Yet his method is classically empiricist in spirit, and a chief motive for these metaphysical explorations is epistemological. The final chapters investigate the perennial question of whether an empiricist, internalist and foundational epistemology can support scientific realism. (shrink)

The reintroduction of Aristotle's Analytics to the Latin West—in particular, the reintroduction of the Posterior Analytics—forever altered the course of medieval epistemological discussions. Although the Analytics fell decidedly from grace in later centuries, the sophisticated account of human cognition developed in the Posterior Analytics appealed so strongly to thirteenth-century European scholars that it became one of the two central theories of knowledge advocated in the later Middle Ages. Robert Grosseteste's 'Commentarius in Posteriorum Analyticorum Libro', written in the 1220s, is (...) most likely the first complete Latin commentary on the Posterior Analytics. As the thirteenth century wore on, Aristotle’s account of human cognition was generally set in opposition to the Augustinian-influenced theory of divine illumination that was de rigueur in the early thirteenth century. Although common consensus holds that this pattern of opposition was set already in Grosseteste’s CPA, I argue that the story of the Posterior Analytics’s early reception is, in fact, quite different. In particular, I maintain that, rather than seeing himself as forced to choose between his earlier theory of divine illumination and the “new” Aristotelian epistemology, Grosseteste is perfectly content to blend and bring together the diverse elements of these systems and to present a consciously synthetic rather than adversarial picture of these differing accounts of human cognition.

Phenomenology is the study of appearance as such. It is a branch of both Ontology and Epistemology, since appearing is being known. By an ‘appearance’ is meant any existent which impinges on consciousness, anything cognized, irrespective of any judgment as to whether it be ‘real’ or ‘illusory.’ The evaluation of a particular appearance as a reality or an illusion is a complex process, involving inductive and deductive logical principles and activities. Opinion has to earn the status of strict knowledge. (...) Knowledge develops from appearances, which may be: (a) objects of perception, i.e. concrete phenomena in the physical or mental domains; (b) objects of intuition, i.e. one’s subjective self, cognitions, volitions and valuations (non-phenomenal concretes); and/or (c) objects of conception, i.e. simple or complex abstracts of preceding appearances. Abstraction relies on apprehensions of sameness and difference between appearances (including received or projected appearances, and projected negations of appearances). Coherence in knowledge (perceptual, intuitive and conceptual) is maintained by apprehensions of compatibility or incompatibility. Words facilitate our construction of conceptual knowledge, thanks to their intentionality. The abstract concepts most words intend are common characters or behaviors of particulars (concrete material, mental or subjective experiences). Granting everything in the world is reducible to waves, ‘universals’ would be equalities or proportionalities in the measures of the features, motions and interrelations of particular waves. Such a theory of universals would elucidate sensation and memory. In attempting to retrace the development of conceptual knowledge from experience, we may refer to certain major organizing principles. It is also important to keep track of the order of things in such development, interrelating specific concepts and specific experiences. By proposing a precise sequence of events, we avoid certain logical fallacies and are challenged to try and answer certain crucial questions in more detail. Many more topics are discussed in the present collection of essays, including selfhood, adduction and other logical issues, the status of mathematical concepts and theology. (shrink)

If the truth of a given sentence, ‘P’ depends upon a certain non-linguistic fact, P then, how is the P without inverted commas involved in the statement, “ ‘P’ is true when P“? How is ‘P’ related to P? My answer suggests that any discussion of these questions leads inevitably to the ancient problem of particulars and universals.

It is also argued that there are substantive grounds for rejecting his classification that clarify the concept of a universal. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Louis Agassiz and the Platonist Story of Creation at Harvard, 1795-1846David K. NartonisIn 1846, naturalist Louis Agassiz took Harvard College by storm with his idealist approach to nature. In his initial lectures, repeated in New York the following year, Agassiz announced, "We have that within ourselves which assures us of participation in the Divine Nature and it is a particular characteristic of man to be able to rise in (...) that way above material Nature, and to understand intellectual existences." He then made it clear that by intellectual existences he meant a divine plan of creation. "What naturalists intend when they speak of what they call 'types'... may be easily understood by comparison. We all know that architects construct our dwellings according to plans conceived by them before the erection of the edifice."1 There is no doubt that Agassiz valued the careful collection of observational data. "It has only been step by step that man has acquired an insight into this plan."2 But his empiricism, if that is the right term, was entirely subordinate to apprehension of divine ideas, which alone deserved to be called science. In one recent account, The Metaphysical Club, which contains an excellent discussion of Agassiz's American career, author Louis Menand accurately describes this dual emphasis on observation and intuition. But Menand leaves unstated the problem of [End Page 437] Agassiz's welcome at Harvard, attributing his instant popularity to force of character.3A fuller explanation of Agassiz's welcome is to be found in the Scottish textbooks that dominated the Harvard philosophy curriculum prior to his arrival.4 Like Agassiz, textbook authors Thomas Reid, Dugald Stewart, and Thomas Brown recognized observation and intuition as twin sources of human knowledge. According to them, we observe our own moral tendencies and interpret them in the light of intuited ethical principles that even God must obey. Similarly, we observe nature and interpret its workings with the aid of intuited principles of common sense.5 There is no doubt that this dual emphasis on observation and intuition was entirely consistent with Agassiz's idealist biology. But his definition of species and genera as intellectual existences in the divine mind was not to be found in the official Scottish texts. In fact, Dugald Stewart, who governed the philosophy curriculum after 1820, insisted that there are "no existences in nature corresponding to general terms, and the objects of our attention in all our general speculations are not ideas but words."6 This was "long misunderstood by philosophers, who imagined that a generic word expresses an actual existence distinct from the individuals of which the genus is composed."7 Similarly, Thomas Brown lamented, "One fundamental error... as long as it retained its hold of the understanding, must have rendered all its energies ineffectual, by wasting them in search of objects, which had no real existence... I allude to... the various orders of universals."8 In this one respect, Stewart and Brown were in agreement with Alexander Pope when he counseled his many American readers "presume not God to scan" and ridiculed those who would "soar with Plato to th' empyreal sphere."9But Harvard students and faculty were also reading books that promoted the intellectual existences that Agassiz saw behind nature and the Scots did [End Page 438] not. Chief among these books were Plato's Works (ca. 360 BCE), Philo's De Opificio Mundi (20 BCE to 50 CE), Ralph Cudworth's The True Intellectual System of the World (1678), and John Norris's An Essay towards the Theory of the Ideal or Intellectual World (1701–04). These combined with such widely popular literature as John Milton's Paradise Lost (1668) and the prose works of Samuel Coleridge to form a kind of unofficial curriculum that ultimately made Agassiz's idealist view of nature especially welcome at Harvard.10 Modest at first, Harvard interest in intellectual existences bloomed with the appearance of books by Romantic writers on campus. In order to illustrate this long development, I will bolster my explanation with data from Harvard College library borrowing records—handwritten lists of the books borrowed by each library user during a one- or two-year period...

This paper investigates the role of pictures in mathematics in the particular case of Cayley graphs—the graphic representations of groups. I shall argue that their principal function in that theory—to provide insight into the abstract structure of groups—is performed employing their visual aspect. I suggest that the application of a visual graph theory in the purely non-visual theory of groups resulted in a new effective approach in which pictures have an essential role. Cayley graphs were initially developed as exact mathematical (...) constructions. Therefore, they are legitimate components of the theory and the pictures of Cayley graphs are a part of practical mathematical procedures. (shrink)

J. Ayer, M. Black, D. M. Armstrong, M. Loux, and others. These criticisms of Russell’s ontological assay of “particularity” have been based on misconstruals of his analysis. The present paper interprets Russell’s analysis, rebuts arguments of his critics, and sets out a (...) different criticism of “bundle” analyses of particulars of the Russellian kind. (shrink)

This paper aims to describe the Cartesian conception on the universals, as well as the way in which this conception could be related to the position developed by Locke in the Essay. Firstly, some considerations about the role of sensorial knowledge in Cartesian philosophy are analyzed. Secondly, some considerations about Locke’s conception of idea are reviewed. Then, the Cartesian concept of universal is reviewed considering his position in the Principia. Finally, Descartes’ and Locke’s view about universals are (...) compared highlighting the role that both thinkers assign to the sensory experience in their theory of knowledge. (shrink)

Many epistemologists use intuitive responses to particular cases as evidence for their theories. Recently, experimental philosophers have challenged the evidential value of intuitions, suggesting that our responses to particular cases are unstable, inconsistent with the responses of the untrained, and swayed by factors such as ethnicity and gender. This paper presents evidence that neither gender nor ethnicity influence epistemic intuitions, and that the standard responses to Gettier cases and the like are widely shared. It argues that epistemic intuitions are (...) produced by the natural ‘mindreading’ capacity that underpins ordinary attributions of belief and knowledge in everyday social interaction. Although this capacity is fallible, its weaknesses are similar to the weaknesses of natural capacities such as sensory perception. Experimentalists who do not wish to be skeptical about ordinary empirical methods have no good reason to be skeptical about epistemic intuitions. (shrink)

While both intuitive knowledge and reason are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge, which Spinoza describes as the ‘greatest virtue of mind’, is superior to reason. The nature of this superiority has been the subject of some controversy due to Spinoza's notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics. In this paper, I argue that intuitive knowledge differs from reason not (...) only in terms of its method of cognition—but also in terms of its content. More specifically, I maintain that there is something that is known by intuition, namely the unique essences of things, that is not known by reason. My argument is supported by an examination of Spinoza's account of essences in the Ethics, which reveals that he is committed to both unique and shared essences. Based on this dual commitment, I argue that whereas for Spinoza both reason and intuition can be said to reach adequate knowledge of the shared essence of a thing, the unique essence of a singular thing, which is nothing but its actual essence, can only be known through intuitive knowledge.

The best known and most widely discussed aspect of Kurt Gödel's philosophy of mathematics is undoubtedly his robust realism or platonism about mathematical objects and mathematical knowledge. This has scandalized many philosophers but probably has done so less in recent years than earlier. Bertrand Russell's report in his autobiography of one or more encounters with Gödel is well known:Gödel turned out to be an unadulterated Platonist, and apparently believed that an eternal “not” was laid up in heaven, where virtuous (...) logicians might hope to meet it hereafter.On this Gödel commented:Concerning my “unadulterated” Platonism, it is no more unadulterated than Russell's own in 1921 when in the Introduction to Mathematical Philosophy … he said, “Logic is concerned with the real world just as truly as zoology, though with its more abstract and general features.” At that time evidently Russell had met the “not” even in this world, but later on under the infuence of Wittgenstein he chose to overlook it.One of the tasks I shall undertake here is to say something about what Gödel's platonism is and why he held it.A feature of Gödel's view is the manner in which he connects it with a strong conception of mathematical intuition, strong in the sense that it appears to be a basic epistemological factor in knowledge of highly abstract mathematics, in particular higher set theory. Other defenders of intuition in the foundations of mathematics, such as Brouwer and the traditional intuitionists, have a much more modest conception of what mathematical intuition will accomplish.

In this paper I address the question 'How is knowledge of logical truths possible'. The sought-after explanation should be independent of what the true story about logical truth is. In particular, I try to account for the epistemic warrant that is conferred upon logical beliefs when they are neither inferred from other beliefs nor grounded on empirical evidence or testimony. The need for such an account is motivated by the apparent failure of the notions ofanalyticity on the one hand (...) and intuition on the other in addressing the relevant question. I end up defending an account according to which warranted logical beliefs can be grounded on pure reasoning: they can be inferentially formed on the basis of pieces of suppositional reasoning.

The tradition descending from Frege and Russell has typically treated theories of meaning either as theories of meanings, or as theories of truth conditions. However, propositions of the classical sort don't exist, and truth conditions can't provide all the information required by a theory of meaning. In this book, one of the world's leading philosophers of language offers a way out of this dilemma. Traditionally conceived, propositions are denizens of a "third realm" beyond mind and matter, "grasped" by mysterious Platonic (...) intuition. As conceived here, they are cognitive-event types in which agents predicate properties and relations of things--in using language, in perception, and in nonlinguistic thought. Because of this, one's acquaintance with, and knowledge of, propositions is acquaintance with, and knowledge of, events of one's cognitive life. This view also solves the problem of "the unity of the proposition" by explaining how propositions can be genuinely representational, and therefore bearers of truth. The problem, in the traditional conception, is that sentences, utterances, and mental states are representational because of the relations they bear to inherently representational Platonic complexes of universals and particulars. Since we have no way of understanding how such structures can be representational, independent of interpretations placed on them by agents, the problem is unsolvable when so conceived. However, when propositions are taken to be cognitive-event types, the order of explanation is reversed and a natural solution emerges. Propositions are representational because they are constitutively related to inherently representational cognitive acts. Strikingly original, What Is Meaning? is a major advance. (shrink)

Public announcement logic is an extension of epistemic logic with dynamic operators that model the effects of all agents simultaneously and publicly acquiring the same piece of information. One of the extensions of PAL, group announcement logic, allows quantification over announcements made by agents. In GAL, it is possible to reason about what groups can achieve by making such announcements. It seems intuitive that this notion of coalitional ability should be closely related to the notion of distributed knowledge, (...) the implicit knowledge of a group. Thus, we study the extension of GAL with distributed knowledge, and in particular possible interaction properties between GAL operators and distributed knowledge. The perhaps surprising result is that, in fact, there are no interaction properties, contrary to intuition. We make this claim precise by providing a sound and complete axiomatisation of GAL with distributed knowledge. We also consider several natural variants of GAL with distributed knowledge, as well as some other related logic, and compare their expressive power. (shrink)

Experimental philosophers have recently conducted surveys of folk judgements about a range of phenomena of interest to philosophy including knowledge, reference, and free will. Some experimental philosophers take these results to undermine the philosophical practice of appealing to intuitions as evidence. I consider several different replies to the suggestion that these results undermine philosophical appeal to intuition, both piecemeal replies which raise concerns about particular surveys, and more general replies. The general replies include the suggestions that the surveys consider (...) the wrong sort of judgement, or the wrong kind of judge, or that the results of the surveys do not generate scepticism about philosophical appeal to intuition in particular, but rather a more problematic and general scepticism. I argue that the last of these general replies is the most promising. To assess its merits, I consider the most developed account of how the survey results are supposed to raise sceptical problems specifically for philosophical appeal to intuition, that presented in Weinberg (Midwest Stud Philos XXXI:318–343, 2007). I argue that there are significant objections to Weinberg’s account. I conclude that, so far, experimental philosophers have failed to show how their survey results raise a sceptical challenge that applies to philosophical appeal to intuition in particular, rather than having a problematic, more general scope.

1. What are called ‘intuitions’ in philosophy are just applications of our ordinary capacities for judgement. We think of them as intuitions when a special kind of scepticism about those capacities is salient. 2. Like scepticism about perception, scepticism about judgement pressures us into conceiving our evidence as facts about our internal psychological states: here, facts about our conscious inclinations to make judgements about some topic rather than facts about the topic itself. But the pressure should be resisted, for it (...) rests on bad epistemology: specifically, on an impossible ideal of unproblematically identifiable evidence. 3. Our resistance to scepticism about judgement is not simply epistemic conservativism, for we resist it on behalf of others as well as ourselves. A reason is needed for thinking that beliefs tend to be true. 4. Evolutionary explanations of the tendency assume what they should explain. Explanations that appeal to constraints on the determination of reference are more promising. Davidson’s truth-maximizing principle of charity is examined but rejected. 5. An alternative principle is defended on which the nature of reference is to maximize knowledge rather than truth. It is related to an externalist conception of mind on which knowing is the central mental state. 6. The knowledge-maximizing principle of charity explains why scenarios for scepticism about judgement do not warrant such scepticism, although it does not explain how we know in any particular case. We should face the fact that evidence is always liable to be contested in philosophy, and stop using talk of intuition to disguise this unpleasant truth from ourselves. (shrink)

Things are particulars and their qualities are universals, but do universals have an existence distinct from the particular things describable by those terms? And what must be their nature if they do? This book provides a careful and assured survey of the central issues of debate surrounding universals, in particular those issues that have been a crucial part of the emergence of contemporary analytic ontology. The book begins with a taxonomy of extreme nominalist, moderate nominalist, and realist (...) positions on properties, and outlines the way each handles the phenomena of predication, resemblance, and abstract reference. The debate about properties and philosophical naturalism is also examined. Different forms of extreme nominalism, moderate nominalism, and minimalist realism are critiqued. Later chapters defend a traditional realist view of universals and examine the objections to realism from various infinite regresses, the difficulties in stating identity conditions for properties, and problems with realist accounts of knowledge of abstract objects. In addition, the debate between Platonists and Aristotelians is examined alongside a discussion of the relationship between properties and an adequate theory of existence. The book's final chapter explores the problem of individuating particulars. The book makes accessible a difficult topic without blunting the sophistication of argument required by a more advanced readership. (shrink)

Rational intuitions involve a particular form of understanding that gives them a special epistemic status. This form of understanding and its epistemic efficacy are not explained by several current theories of rational intuition, including Phenomenal Conservatism (Huemer, Skepticism and the veil of perception, 2001 ; Ethical intuitionism, 2005 ; Philos Phenomenol Res 74:30–55, 2007 ), Proper Functionalism (Plantinga, Warrant and proper function, 1993 ), the Competency Theory (Bealer Pac Philos Q 81:1–30, 2000 ; Sosa, A virtue epistemology, 2007 ) and (...) the Direct Awareness View (Conee, Philos Phenomenol Res 4:847–857, 1998 ; Bonjour, In defense of pure reason, 1998 ). Some overlook it; others try to account for it but fail. We can account for the role of understanding in rational intuition by returning to the view of some of the early Rationalists, e.g. Descartes and Leibniz. While that view carries a prohibitive cost, it does contain an insight that may help us solve the problem of giving understanding its due. (shrink)

Certainty The following article provides an overview of the philosophical debate surrounding certainty. It does so in light of distinctions that can be drawn between objective, psychological, and epistemic certainty. Certainty consists of a valuable cognitive standing, which is often seen as an ideal. It is indeed natural to evaluate lesser cognitive standings, in particular … Continue reading Certainty →.
