This is an impressive and important book about perception in Plato’s Timaeus, but most of its readers will probably be researchers who are interested in much broader questions about the dialogue. There is nothing deficient or lacking about this treatment of perception, but this book should be put alongside Thomas Johansen’s Plato’s Natural Philosophy and Sarah Broadie’s Nature and Divinity in the sense that this is, for all intents and purposes, a monograph about the whole Timaeus, even (...) though it is pitched as being focused on perception. There are only a few topics missing, such as the nature of the cosmic receptacle and psychic diseases. Virtually everything else, including the status of Timaeus’ so-called likely story, the generation of the lower gods, and the nature of bone, is discussed at length. (shrink)

Perception is the ultimate source of our knowledge about contingent facts. It is an extremely important philosophical development that starting in the last quarter of the twentieth century, philosophers have begun to change how they think of perception. The traditional view of perception focussed on sensory receptors; it has become clear, however, that perceptual systems radically transform the output of these receptors, yielding content concerning objects and events in the external world. Adequate understanding of this process requires (...) that we think of perception in new ways—how it operates, the differences among the modalities, and integration of content provided by the individual senses. Philosophers have developed new analytic tools, and opened themselves up to new ways of thinking about the relationship of perception to knowledge. The Oxford Handbook of the Philosophy of Perception is a collection of entries by leading researchers that reviews these new directions in philosophical thought. The Introduction to the Handbook reviews the history of the subject from its beginnings in ancient Greece to the nineteenth century, and the way that science and philosophy have together produced new conceptions during the last hundred years. It shows how the new thinking about perception has led to a complex web of theories. (shrink)

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, (...) the question can be confused with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. (shrink)

Historically embryogenesis has been among the most philosophically intriguing phenomena. In this paper I focus on one aspect of biological development that was particularly perplexing to the ancients: self-organisation. For many ancients, the fact that an organism determines the important features of its own development required a special model for understanding how this was possible. This was especially true for Aristotle, Alexander, and Simplicius, who all looked to contemporary technology to supply that model. However, they did not all agree on (...) what kind of device should be used. In this paper I explore the way these ancients made use of technology as a model for the developing embryo. I argue that their different choices of device reveal fundamental differences in the way each thinker understood the nature of biological development itself. In the final section of the paper I challenge the traditional view (dating back to Alexander's interpretation of Aristotle) that the use of automata in GA can simply be read off from their use in the de motu.

This dissertation examines the theory of perceptual cognition laid out by the 7th century Buddhist scholar, Dharmakīrti, in his magnum opus, the Pramāṇavārttika. Like most theories of perception, both ancient and modern, the sensory cognition of ordinary objects is a topic of primary concern. Unlike other theorists, however, Dharmakīrti advances a technical definition of “perception” as a cognition which is both nonconceptual and non-erroneous. Dharmakīrti’s definition of perception is thereby deliberately inclusive of three additional types of (...) “perceptual” cognition, in addition to veridical sensory awareness: the nonconceptual mental apprehension of an immediately-preceding cognition (“mental perception”), the vivid appearance of soteriologically efficacious objects of contemplative practice (“yogic perception”), and the sheer unmediated presence of the contents of cognition—whatever these might be—to the cognizing mind (“reflexive awareness”). Through the logical examination of what it means to be aware of an object, Dharmakīrti demonstrates that the awareness of an object is just the awareness of a phenomenal form or cognitive image produced by that object. Pursuing this analysis further, however, Dharmakīrti argues that the very notion of an object of cognition that exists “externally” or outside the mind is incoherent. Additionally, Dharmakīrti maintains that the phenomenological structure of subject and object—that is, the “first-personal” sense of one’s own cognitions as pertaining to oneself (“for-me-ness”), together with the inseparably concomitant sense that the objects of cognition exist “out there” in an extramental world—is strictly a form of cognitive error. Therefore, because ordinary sensory cognition is inherently structured by this subject-object duality, ordinary sensory cognition must in the final analysis be understood as erroneous. According to Dharmakīrti, in other words, ultimately only the nondual “luminosity” of reflexive awareness is genuinely perceptual, because only reflexive awareness is undistorted by nature. In this way, Dharmakīrti’s epistemology provides a theoretical foundation for the advanced nondual contemplative practices of Indian and Tibetan Buddhism, particularly Mahāmudrā and rDzogs chen.

This volume focuses on philosophical problems concerning sense perception in the history of philosophy. It consists of thirteen essays that analyse the philosophical tradition originating in Aristotle’s writings. Each essay tackles a particular problem that tests the limits of Aristotle’s theory of perception and develops it in new directions. The problems discussed range from simultaneous perception to causality in perception, from the representational nature of sense-objects to the role of conscious attention, and from the physical/mental (...) divide to perception as quasi-rational judgement. -/- The volume gives an equal footing to Greek, Arabic, and Latin philosophical traditions. It makes a substantial contribution not just to the study of the Aristotelian analysis of sense perception, but to its reception in the commentary tradition and beyond. Thus, the papers address developments in Alexander of Aphrodisias, Themistius, Avicenna, John of Jandun, Nicole Oresme, and Sayf al-Din al-Amidi, among others. The result of this is a coherent collection that attacks a well-defined topic from a wide range of perspectives and across philosophical traditions. (shrink)

Ancient Chinese history holds a quality which has syncretized traditional thought with its cultural wealth unified of mystical and mythological figures in the background. Such that classical documents, which had begun to be written before Common Era, has directly influenced the political regime, education system and status of society in China. One of the most prominent features of these works is to propound collective knowledge about perception of cosmology, attitudes to earthiness, community standards, policy and morality. Among Five (...) Classics works of these masterpieces of Chinese philosophy, Book of Changes which stands closest to metaphysical narrative, mainly consists of the texts about prophecy. While this piece of work had been referred as a divination guide in Western Zhou Dynasty (1046-771 BC), it turned into a cosmological text that included a range of philosophical commentary during Warring States Period (475-221 BC). The mainstay of this remarkable change is the direct correlation of all the concepts and terms that characterize the worldly beyond along with the relevant text, especially yin-yang dualism, which symbolizes an extraordinary harmony in early Chinese thought. Traditional idea suggests reciprocity in which heaven, earth and man are interconnected to maintain natural order. However, the superiority attributed to human beings also brings compulsive responsibilities to idealize a compatible society. This paper aims to discuss influences of cosmological and anthropological items on human behaviors explained in prescriptive perspective. (shrink)

The article focuses on an unexamined so far aspect of byzantine philosophy, namely the influence of Arabic philosophy upon byzantine thinkers. Despite the vicinity of Byzantium and Arabic territories, the philosophical interactions were minimal. Scholarios claimed, in a dedicatory epistle to Constantine Paleologus (1405-1453), that he had studied the treatises of Avicenna, Averroes, and other Arab and Persian philosophers. He admitted that Averroes was beyond doubt the best commentator of Aristotle. Scholarios acknowledged that the study of the Arabs (...) contributed immensely to his philosophical education and particularly to the proper understanding of the Aristotelian philosophy (Scholarios, vii.1-6). Scholarios aimed at the enrichment and renewal of Byzantine philosophy. Besides his high esteem for Arabic philosophy, he devoted a large part of his life translating and paraphrasing the Scholastics, especially Aquinas. Despite Scolarios’ claim about his erudition on the Arab and Persian philosophers, a detailed examination of his works proves that in most cases he simply reproduced and incorporated sections from Aquinas’ works, without resorting to the original sources. Scholarios’ references to the Arabs are multiplied in his translations and compendia of Aquinas’ works, but are reduced significantly in his original texts. Frequently Scholarios refrained from mentioning the Arab philosophers, despite the fact that he commented on Aquinas’ passages, which are dedicated to Avicenna or Averroes. On the contrary, Scholarios did not avoid mentioning in detail Aquinas’ Christian or ancient Greek sources. It is obvious that Scholarios did not have a consistent approach towards Arabic philosophy. Most of the times he reproduced loosely Aquinas’ passages, where the latter commented on the Arabs. (shrink)

The second half of the 20th century may fairly be considered a golden age for the study of ancient philosophy. This period witnessed the creation of four English-language journals for specialists and two professional societies. Throughout this period there were numerous regional and national conferences, reading groups, NEH-sponsored summer seminars and institutes on various aspects of ancient thought, successful graduate programs in ancient philosophy at a sizable number of American universities, and a steady supply of (...) jobs for specialists in the field. Seminal studies by Gregory Vlastos and G.E.L. Owen stimulated broad interest in ancient Greek philosophy by showing how the methods and issues explored by ancient thinkers were relevant to contemporary philosophical debates. On a less happy note, in recent years some influential analytic philosophers have discounted the value of work in the history of philosophy, and public funding for philosophy, along with other humanities fields, has declined sharply. -/- .

This chapter aims to illuminate ways in which hope was significant in the philosophy of classical Greece. Although ancient Greek philosophies contain few dedicated and systematic expositions on the nature of hope, they nevertheless include important remarks relating hope to the good life, to reason and deliberation, and to psychological phenomena such as memory, imagination, fear, motivation, and pleasure. After an introductory discussion of Hesiod and Heraclitus, the chapter focuses on Plato and Aristotle. Consideration is given both to (...) Plato’s direct comments on hope and to the narrative contexts of his dialogues, with analysis of Plato’s positive and negative representations of hope, hope’s relationship to reason, and Plato’s more psychological approach in the Philebus, where hope finds a place among memory, recollection, pleasure, and pain. The chapter then reviews Aristotle’s discussions of confidence, hope, and courage, observing that although Aristotle does not mention hope as a virtue, he does note its importance to human agency and deliberation and as a foundation for the further development of virtue. The chapter concludes that discussions surrounding hope in ancient Greek philosophy are rich and challenging and can serve as a lively stimulus to further exploration of the concept of hope.

This paper is about the history of a question in ancient Greek philosophy and medicine: what holds the parts of a whole together? The idea that there is a single cause responsible for cohesion is usually associated with the Stoics. They refer to it as the synectic cause (αἴτιον συνεκτικόν), a term variously translated as ‘cohesive cause,’ ‘containing cause’ or ‘sustaining cause.’ The Stoics, however, are neither the first nor the only thinkers to raise this question or to (...) propose a single answer. Many earlier thinkers offer their own candidates for what actively binds parts together, with differing implications not only for why we are wholes rather than heaps, but also why our bodies inevitably become diseased and fall apart. This paper assembles, up to the time of the Stoics, one part of the history of such a cause: what is called ‘the synechon’ (τὸ συνέχον) – that which holds things together. Starting with our earliest evidence from Anaximenes (sixth century BCE), the paper looks at different candidates and especially the models and metaphors for thinking about causes of cohesion which were proposed by different philosophers and doctors including Empedocles, early Greek doctors, Diogenes of Apollonia, Plato and Aristotle. My goal is to explore why these candidates and models were proposed and how later philosophical objections to them led to changes in how causes of cohesion were understood. (shrink)

This is the editors' Introduction to a special issue of the journal, Multisensory Research. European philosophers of the modern period found multisensory perception to be impossible because they thought that perceptual ideas are defined by how they are experienced. Under this conception, the individual modalities are determinables of ideas—just as colour is a determinable that embraces red and blue, so also the visual is a determinable that embraces colour and (visually experienced) shape. Since no idea is experienced as, for (...) example, both visual and auditory, there can be no such thing as audiovisual perception. This conception of modality is not directly contested, but a variety of perceptual phenomena are listed that could raise interesting questions if treated as multimodal in origin. (shrink)

We consider semantic and syntactic transformations of the concept of "the logical" in the ancient philosophy in the form of crypto-logos, para-logismos, dia-logos, and syl-logismos. We interpret Heraclitus' concept of Logos as a cryptologos through which intuitive insight (epístasthai gnóomen) reveals hidden or implicit harmony (harmoníe aphanés) in nature (phýsis) as a conceptual unity of ontic opposites (tà enantía). In Pramenides' paraconsistent concept of the identity of Being and thought, we point to para-logical hypotheses about the One that (...) are carried out through antithetical deductions of thought and which maintain the dynamics of the ontic determinations of being (ón) in the statics of the conceptual determinations of Being (tò eînai). As the beginning of the explicative granulation of ''the logical'' we consider Plato's concept of the dialectical skill (dialektikè tékhne) of dividing concepts of genus into species and sub-species that logically represent ontic opposites in problem-formulated questions. Finally Aristotle's concept of lógos as a statement-making sentence / proposition (lógos apophantikós) made explicit the Being (tò eînai), or the Being as Being (tò ón hê ón), in semantic and syntactic figures and modes of syllogistic inferences in which ontological (eînai), ontic (ón), conceptual (logikôos) and linguistic (légomenon) correspondence is shown. We conclude that with these changes in the concept of lógos, the path has been taken from the hidden or implicit Truth of the phenomena of nature and the world (pân) to explicit truthfulness of propositions as the unhiddeness (alétheia) of Being trough the semantical and syntactical visibility of the logical structures of being, thought and language in scientific knowledge based on demonstration (apoódeiksis).

Husserl famously argues that it is essential to perception to present the perceived object in perspectives. Hence, there is no – and there cannot be – perception without perspectival givenness. Yet, it seems that there are counterexamples to this essentialist claim, for we seem to be able to imagine beings that do not perceive in perspectives. Recently, there have been some accounts in the literature that critically discuss those counterexamples and assess to what extent they succeed in challenging (...) Husserl’s essentialist claim. In this paper I discuss three different answers to these counterexamples, all of them are found wanting. I offer a novel solution, taking into account some crucial findings of the contemporary debate about imagination and modality. I argue that this new solution is capable of fully vindicating Husserl’s essentialist claim. Finally, I reconstruct Husserl’s own way to treat such counterexamples, in order to showcase the notion of modality Husserlian phenomenology relies on. I argue for the hitherto widely underappreciated point that Husserl’s transcendental phenomenology cannot appeal to strictly absolute modality but that the kind of modality in Husserlian phenomenology is conditional on the facticity that we have the transcendental structure we do in fact have.

Ancient philosophy has, for the most part, focused particularly around the history and philosophies of the Pre-Socratics, Socrates, Plato and Aristotle, with broader representations of some other non-Greek philosophical traditions such as the Chinese, Indian and Iranian philosophies. However, a distinctive Eurocentric bias towards ancient Egypt, to which many ancient Greek philosophers looked to as the cradle of wisdom and philosophy, has blatantly disregarded the poignant place of African philosophy in the pedagogy of (...) class='Hi'>ancient philosophy. Thus, this paper argues for re-centering ancient Egyptian philosophy, and by extension, African philosophy in the study of ancient philosophy. The paper, firstly, traces the historical originality and rich elements of philosophy that ancient Egypt possesses, and then, identifies how these served as the theoretical springboard for the emergence of Greek philosophy. Any comprehensive study of ancient philosophy should not deliberately exclude this important aspect of development in philosophical thought. The paper, therefore, concludes with recommendations on repositioning African philosophy within the pedagogical context of ancient philosophy. (shrink)

In this paper, I explore Augustine’s account of sense cognition in book 11 of De Trinitate. His discussion in this context focuses on two types of sensory state—what he calls “outer vision” and “inner vision,” respectively. His analysis of both types of state is designed to show that cognitive acts involving external and internal sense faculties are susceptible of a kind of trinitarian analysis. A common way to read De Trin. 11, is to interpret Augustine’s account of “outer” vision as (...) an analysis of sense perception and his account “inner” vision as an analysis of occurrent sensory memory and imagination. I argue against such a reading of De Trin. 11, however. Insofar as we take perception to be a phenomenally conscious mode of sensory awareness, outer vision cannot, I claim, be the equivalent of ordinary sense perception. For, on Augustine’s view, the deliverances of outer vision only reach the threshold of consciousness, when outer vision occurs in conjunction with inner vision. Hence, on my analysis, sense perception turns out to be a complex, hybrid state—one that involves both outer and inner vision. If I am right, acts of sense perception turn out not to be directly susceptible to trinitarian analysis. Even so, the account is interesting and nuanced for all that. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

In De Anima III.3 Aristotle presents his official discussion of phantasia (“imagination” in most translations). At the very outset of the discussion Aristotle offers as an endoxon that “phantasia is that in virtue of which we say that a phantasma occurs to us” (428a1-2). Now a natural reading of this claim, taken up by many commentators, can pose a problem for Aristotle’s overall account of perception. Here I argue that, although it would be silly to deny that Aristotle considers (...) phantasia to be that in virtue of which a phantasma occurs to someone, it is not silly to deny that phantasmata are present in every case in which phantasia is operative. This suggestion bolsters the idea that, according to Aristotle’s account of veridical perception, we can understand the world as making itself perceptually manifest to the perceiver. (shrink)

(Shoshana Smith now goes by her married name, Shoshana Brassfield: http://philpapers.org/profile/37640) Descartes famously claims that everything we perceive clearly and distinctly is true. Although this rule is fundamental to Descartes’s theory of knowledge, readers from Gassendi and Leibniz onward have complained that unless Descartes can say explicitly what clear and distinct perception is, how we know when we have it, and why it cannot be wrong, then the rule is empty. I offer a detailed analysis of clear and distinct (...) perception, showing how Descartes answers these questions. Many doubts about the usefulness of the clarity and distinctness rule arise from the mistaken assumption that in clear and distinct perception, like sense perception, we must be able to establish a correspondence between perception and reality before we can have knowledge. I show that Descartes has a different metaphysical picture of clear and distinct perception. Clear and distinct perception is direct perception, typically of essences. On this view, by relying on the intellect instead of the senses, we can have direct perception not only of our own ideas, but also of a mind-independent reality. Because clear and distinct perception is direct perception, problems of correspondence do not arise. My account of clear and distinct perception also yields unique insight into other issues in Descartes, such as the Cartesian Circle and the doctrine of the free creation of the eternal truths.

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and (...) which ‘subjective’? What properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

How is it possible that emotions in the community can be influenced by media? According to the paper’s concept, this is only understandable if we accept with Marshall McLuhan that media and the human body are not separable. There is no divide. The medium is the message expressed through the body/human being. This has preconditions, because the connection must be based on an analog principle that serves as the transmitter. This lies in non-discursive affectively relevant forms and an equally affectively (...) evaluative mode of perception, as empirical research now confirms. On this basis, as Daniel N. Stern shows, people operate “with vigorous goal-directedness to assure social interactions.” This points to the second premise, that every body/human being – infallibly – perceives a promise in communion with others, namely that of happiness, security, and community. This concept has far-reaching implications for how communities understand themselves, as the research of poststructuralists and frame theorists demonstrates, and as the trial and death of Socrates in ancient Athens attests.

Both perception and imagination seem to play a crucial role in our engagement with fiction films but whether they really do so, and which role they possibly play, is controversial. On the one hand, a fiction film, as film, is a depiction that invites us to perceive the events portrayed. On the other hand, as fiction, it invites us to imagine the story told. Thus, after watching the film Alien, one might say that one saw Ripley fighting the monster (...) but one might also say that one imagined Ripley fighting the monster. Are these two reports compatible? If they are, how can we combine them so to make sense of them? If, instead, they are not, which of them should we give up? (shrink)

This book offers inter alia a systematic investigation of the actual argumentative strategy of Socratic conversation and explorations of Socratic and Platonic morality including an examination ofeudaimonia and the mental conception of health in the Republic as self-control, with a view to the relation of individual health/happiness to social order. The essays cover a period from 1968 to 2012. Some of them are now published for the first time. Self-motion in the later dialogues involves tripartition and tripartition in turn involves (...) embodiment. The Philebus psychology too anticipates Aristotle. The Forms of the Timaeus are patterns, but the two-world picture is abandoned: there is one world constituted by Forms and Place. The Epinomis is arguably genuine. More generally, denying that Plato develops, e.g. exegetically and psychologically, is absurd. There are too many contradictions in the Corpus. The dialogues are artistic wholes and the author's message must be interpreted accordingly: hence in a sense every character is Plato's mouthpiece. Aristotle's idea of the human good or quality of life as optimal mental activity according to the special human capabilities is the root of the modern selfactualization projects. Panaetius (free reason) and Posidonius (science) mark the end of the older Stoa's hard-core materialism and the beginning of a new more 'modern' era. -/- . (shrink)

This paper examines an ancient debate over the rationality of perception. What leads the Stoics to affirm, and the Epicureans to deny, that to form a sense-impression is an activity of reason? The answer, we argue, lies in a disagreement over what is required for epistemic success. For the Stoics, epistemic success consists in believing the right propositions, and only rational states, in virtue of their predicational structure, put us in touch with propositions. Since they identify some sense-impressions (...) as criteria of truth and thus as the basis for epistemic success, the Stoics maintain that sense-impressions must be rational. The Epicureans agree with the Stoics that sense-impressions function as criteria of truth, and also agree broadly on what it means for a state to be rational, but deny that sense-impressions are rational because (1) they think that epistemic success must be supported by a state that is necessarily error-free and (2) accept that rational states can be false. In reconstructing this debate, we refine the standard interpretation of the fundamental difference between Epicurean and Stoic epistemology and also develop parallels with epistemological debates today. One upshot is a more nuanced appreciation of the merits of Epicurean epistemology vis-à-vis the Stoics. (shrink)

A recurring theme dominates recent philosophical debates about the nature of conscious perception: naïve realism’s opponents claim that the view is directly contradicted by empirical science. I argue that, despite their current popularity, empirical arguments against naïve realism are fundamentally flawed. The non-empirical premises needed to get from empirical scientific findings to substantive philosophical conclusions are ones the naïve realist is known to reject. Even granting the contentious premises, the empirical findings do not undermine the theory, given its overall (...) philosophical commitments. Thus, contemporary empirical research fails to supply any new argumentative force against naïve realism. I conclude that, as philosophers of mind, we would be better served spending a bit less time trying to wield empirical science as a cudgel against our opponents, and a bit more time working through the implications of each other’s views – something we can accomplish perfectly well from the comfort of our armchairs.

In his adventurous monograph in comparative philosophy, The Origins of Philosophy in Ancient Greece and Ancient India, Richard Seaford offers to explain why philosophy, which on his account originated in the sixth century BCE separately in both Greece and India, took such a similar form in both cultures.

In book 10 of the Republic we find a new argument for the division of the soul. The argument’s structure is similar to the arguments in book 4 but, unlike those arguments, it centres on a purely cognitive conflict: believing and disbelieving the same thing, at the same time. The argument presents two interpretive difficulties. First, it assumes that a conflict between a belief and an appearance—e.g. disbelieving that a stick partially immersed in water is, as it appears, bent—entails a (...) conflict between beliefs. Prima facie, there is only one belief, the belief that contradicts the appearance. Second, it is unclear what parts of the soul Plato intends to divide between: some argue that it is, as in book 4, a partition between a rational and a non-rational part; others argue that it is a new partition between a higher and a lower subdivision of the rational part. This paper offers solutions to both difficulties through an analysis of what Plato means by φαινόμενα, ‘appearances’, and δόξαι, ‘beliefs’. It is argued, first, that the relevant appearances are entirely sensory but nonetheless sufficiently belief-like to (a) warrant being called δόξαι and (b) oppose, by themselves, our beliefs; there is no need for a third mental state, a belief that assents to the appearance. A second claim concerns a central line in the argument, 602e4–6, that has served as the primary evidence that the partition is within the rational part of the soul. Those who wish to avoid this conclusion generally resort to alternative, and less natural, translations of 602e4–6. It is argued that this is unnecessary: once we have correctly understood sensory appearances, we see that the standard translation of 602e4–6 in fact entails a division between a rational and a non-rational part of the soul.

We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify figure-ground segmentation, (...) while seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)

This awareness will further be used to prepare a flow-chart / block-diagram involving gross energy -transformations in human cognitive process. -/- This awareness will be corresponded to the awareness of Sri Aurobindo and Sri Ramana Maharshi on human consciousness. Implications of this model to natural language comprehension field of artificial intelligence will be presented combining with the ideas of connectionism. -/- . (shrink)

Two of the most basic commitments of virtue ethics, both ancient and contemporary, are that virtue is knowledge and that this knowledge is a kind of moral sensitivity that is best understood on the model of perception. On this account, the virtuous agent perceives moral goodness and badness in something like the way we perceive that a smiling person is happy or that a raging bull is dangerous. This is opposed to the more widely held view of moral (...) experience, according to which perception informs us only of nonmoral states of affairs; the specifically moral content of the experience, on this view, comes either from distinct pro or con attitudes toward those states of affairs or from general principles that we apply...

The practical aspect of ancient philosophy has been recently made a focus of renewed metaphilosophical investigation. After a brief presentation of three accounts of this kind developed by Martha Nussbaum, Pierre Hadot, and Michel Foucault, the model of the therapeutic argument developed by Nussbaum is called into question from the perspectives offered by her French colleagues, who emphasize spiritual exercise (Hadot) or the care of the self (Foucault). The ways in which the account of Nussbaum can be defended (...) are then discussed, including both a ‘negative’ defense, i.e. the indication of the weaknesses of Hadot and Foucault’s proposals, and a ‘positive’ one focused on the points in which Nussbaum can convincingly address doubts about her metaphilosophical account. In response to these analyses, some further remarks made by Hadot and Foucault are discussed in order to demonstrate that their accounts are not as distant from Nussbaum after all. Finally, a recent metaphilosophical study by John Sellars together with a therapeutic (medical) model developed by the author of the present article are suggested as providing a framework for potential reconciliation between all three accounts discussed and a resource for further metaphilosophical studies.

It has been widely acknowledged that indexical thought poses a problem for traditional theories of mental content. However, recent work in philosophy has defied this received view and challenged its defenders not to rely on intuitions but rather to clearly articulate what the problem is supposed to be. For example, in “The Inessential Indexical”, Cappelen and Dever claim that there are no philosophically interesting or important roles played by essential indexical representations. This paper assesses the role of essential indexicality (...) in understanding the content of perception and argues that, if the perceptual experiences of different subjects can have the same phenomenology, and thus share a representational content (phenomenal content)—assumptions shared by a well-established research project, including a wide variety of theories—, then phenomenal content exhibit a particular kind of essential indexicality (perspectival). I also discuss how the argument is immune to Cappelen and Dever’s objections to the idea that the content of perceptual experiences is essentially indexical. (shrink)

This textbook has been written to discuss the fundamental problems of Greek Philosophy. There has been many philosophical Problems which Greek philosophers has discussed and examined with rational approach. The philosophical problems which we have mentioned in this book are: Greek Rationalism, Greek Naturalism, Greek Idealism, Greeks on human mind, Number theory and Greek Metaphysics. We have defined some significant issues like Greek atomism, Nihilism, Solipsism, Dogmatism, Sophism and Pluralism. Philosophy is the subject which studies the fundamental Problems (...) of the world. The problems which Philosophy studies are reality, existence, mind, thought, language, essence, experience, perception, knowledge, God, and so on. This book ‘Problems of Greek Philosophy’ is divided into six chapters while first Chapter ‘Introduction to western Philosophy’ deals with overall discussion and argumentation of western philosophy and also some valuable introductory information on Greek Philosophy. Second Chapter ‘Greeks on Nature’ attempts to discuss the lonian classification and examination of natural elements like water, air, Aperion, fire and reality. This chapter deals with the ultimate constituents of the natural stuff. Third chapter ‘Greek Rationalism’ deals with the role of reason in explanation of the world. Greek rationalists have used reason as the fundamental constituent of the universe. Fourth chapter ‘Number theory and Greek Metaphysics’ deals with the contribution of great mathematicians like Pythagoras and Zeno to the world. This chapter has highlighted the philosophy of number and metaphysics. Fifth Chapter ‘Greek Idealism’ highlights the philosophy of Greek idealists; Protagoras, Socrates and Plato. Sixth Chapter ‘Mind in Greek Philosophy’ deals with the concept of mind and thought in Greek philosophy. This section examines the contribution of Anaxagoras and Empedocles. (shrink)

This chapter investigates the precise ways in which Antonio Gramsci engaged with ancient philosophy. A brief examination of the longest discussion in the Prison Notebooks of any ancient philosopher or text, Plato’s Republic (Q8, §22), raises many questions about Gramsci’s approach to ancient philosophy. These questions motivate an investigation into Gramsci’s surprisingly minimal discussion of ancient philosophy and philosophers, which is best explained in the light of his theoretical commitments to his distinctive species (...) of historical materialism. Rather than responding to specific critical insights advanced about politics or human nature by ancient philosophers, such as Plato and Aristotle, Gramsci is shown to appropriate ancient philosophy into a broad-spectrum project of the history of philosophy, which interrogates the specific conditions under which historical epochs and the philosophical ideas that characterise them emerge. Tracking the conditions and characteristic ideas is revealed to be the project of the ‘specialist philosopher’, who must grasp both general methodological principles and particular historical examples. Gramsci’s treatment of ancient philosophy reveals more about his universal theories of history, and his engagement with the ideas of his contemporaries (including Benedetto Croce), than a special concern with ancient philosophy itself.

Discussions of Aristotle’s Metaphysics Z tend to treat it either as an independent treatise on substance and essence or as preliminary to the main conclusions of the Metaphysics. I argue instead that Z is central to Aristotle’s project of first philosophy in the Metaphysics: the first philosopher seeks the first causes of being qua being, especially substances, and in Z, Aristotle establishes that essences or forms are the first causes of being of perceptible substances. I also argue that the (...) centrality of Z to first philosophy is compatible with its status as theology. (shrink)

The Stoics thought that knowledge depends on a special kind of appearances which they called ‘apprehensive’, which are by definition true. Interestingly, Sextus Empiricus reports in M 7.247 that they held that there are appearances that are true but that are not apprehensive because they are true merely by chance and thus cannot constitute knowledge. I believe that this suggests that the Stoics were aware of what is in modern literature known as the problem of epistemic luck. Unfortunately, Sextus’ report (...) leaves out a lot of important details, which makes it difficult to understand exactly which appearances the Stoics thought are true by chance, and why. I argue that the true non-apprehensive appearances in question here are imaginations, representational states which are not immediately caused by external objects through perception, but produced solely by the mind. I propose an explanation why the Stoics, who defined chance in terms of hidden causes, would have thought that imaginations can only be true by chance. The explanation stems from their view that the essential characteristic of imagination is that it leaves the actual cause of its representational content hidden from the subject. (shrink)

ABSTRACT The philosophical tradition approaches to morals have their grounds predominantly on metaphysical and theological concepts and theories. Among the traditional ethics concepts, the most prominent is the Divine Command Theory (DCT). As per the DCT, God gives moral foundations to the humankind by its creation and through Revelation. Morality and Divinity are inseparable since the most remote civilization. These concepts submerge in a theological framework and are largely accepted by most followers of the three Abrahamic traditions: Judaism, Christianity, and (...) Islam: the greatest part of the human population. Holding faith and Revelation for its grounds, the Divine Command Theories are not strictly subject to the demonstration. The opponents to the Divine Command conception of morals, grounded in the impossibility of demonstration of its metaphysical and religious assumptions, have tried for many centuries (albeit unsuccessfully) to devalue its importance. They held the argument that it does not show material evidence and logical coherence and, for this reason, cannot be taken into account for scientific nor philosophical purposes. It is just a belief and, as so, should be understood. Besides these extreme oppositions, many other concepts contravene the Divine Command theories, in one or another way, in part or in full. Many philosophers and social scientists, from the classic Greek philosophy up to the present date, for instance, sustain that morality is only a construct, and thus culturally relative and culturally determined. However, this brings many other discussions and imposes the challenge to determine what is the meaning of culture, which elements of culture are morally determinant, and finally, what are the boundaries of such relativity. Moral determinists claim that everything related to human behavior, including morality, is determined, once free will does not exist. More recently, modern thinkers argued that there is a strict science of morality. However, the scientific method alone, despite explaining several facts and evidence, cannot enlighten the entire content and full meaning of ethics. Morals’ understanding requires a broader perception, and an agreement among philosophers, which they have never achieved. All of these questions have many different configurations depending on each philosophical strand, and start complex analysis and endless debates, as long as many of them are reciprocally conflictive. The universe and the atmosphere involving this thesis are the dominions of all these conceptual conflicts, observed from an objective and evolutionary standpoint. Irrespective of this circumstance and its intrinsic importance, however, these questions are far distant from the methodological approach of an analytical discussion on objective morals, what is, indeed, the aim and scope of this work. We should briefly revisit these prominent traditional theories because this thesis shelters a comparative study, and its assumptions at least differ profoundly from all traditional theories. Therefore, it becomes necessary offering direct and specific elements of comparison to the reader, for the right criticism, dispensing interruptive researches. However, even revisiting the traditional theories, for this comparative and critical exposure purpose, they will be kept by the side of our main concerns, as “aliena materia.” Irrespective of the validity of any or all of the elements of this discussion, and their meaning as the philosophical universe of this thesis, the purpose of this work is demonstrating and justifying the existence and meaning of prehistoric moral archetypes arisen directly from the very first social needs and efforts for survival. These archetypes are the definition of the essential foundation of ethics, its aggregation to the collective unconscious and corresponding logic organization and transmission to evolutionary stages of the human genome and different relations space-time, irrespective of any contemporary experience of the individuals. The system defined by these archetypes composes an evolutionary human social model. Is this a metaethical position? Yes, it is. Moreover, as in any metaethical reasoning, we should look carefully for the best and coherent routes, as the Analytical Philosophy offers them. Thus, this work should reasonably demonstrate that morals are not a cultural product of the civilized men or modern societies and that despite being subject to several cultural relative aggregations and subtractions, its essential foundations are archetypal and have never structurally changed. This reasoning induces that morality is an original attribute of the “homo sapiens”; it is not a property and nor an accident: it integrates the human essence and belongs to the realm of the ontological human identity. The human phenomena is a continuing process, playing its role between random determination and free will, and we need to question how morality began and how did it come to us in the present.

Phenomenology and ancient Greek philosophy. The title of this book, indicating these topics as its two main subjects, could give the impression that the subjects are held together by a circumstantial “and.” The title would then indicate a connection between phenomenology and a topic, ancient Greek philosophy, the way titles such as Art and Phenomenology, Phenomenology and Psychological Research, Phenomenology and Virtue Ethics do. This impression would be wrong. First, ancient Greek philosophers take pride of (...) place in the dialogues initiated by many phenomenologists with various figures from the history of philosophy. Second, this is not just because phenomenological philosophers have tended to regard ancient Greek philosophy as the revered beginning of Western thought, reflection upon which may help illuminate any topic modern human beings wish to inquire into or give it a kind of historical dignity. It is first and foremost because ancient Greek philosophy, understood as the scientific attempt to understand the world, ourselves, and our place in the world, in the phenomenological tradition is regarded as one important origin of contemporary Western philosophy and science, even if contemporary philosophy and science is also determined by a new ideal of philosophy that emerges in early modernity. Indeed, for most phenomenologists, Greek philosophy can be regarded as the roots supporting this new ideal—even if these roots are sometimes hidden from sight or forgotten. The main rationale for confronting ancient Greek philosophy phenomenologically is accordingly the attempt to bring to light in its full radicality the phenomenon “philosophy.” Unearthing philosophy as it was originally understood by Greek thinkers may, according to many phenomenologists at least, help us understand what philosophy in the full sense of the word was, has been, and may be again, but also what it has become or even degenerated into in modern times, for instance positivism. It is this way of approaching ancient Greek philosophy that we wish to concentrate on in this book, in the hope that the volume will prove instructive both to people who have an interest in ancient Greek philosophy and wish to know more about the phenomenological approach to it and to people who work within phenomenology and wish to know more about the various approaches to ancient Greek philosophy characterizing the phenomenological movement. We have therefore sought to make the introduction and the individual chapters accessible to non-experts, for instance by transliterating all Greek text, and confining quotes in other languages than English to footnotes and glosses.

George Berkeley's linguistic account of sense perception is one of the most central tenets of his philosophy. It is intended as a solution to a wide range of critical issues in both metaphysics and theology. However, it is not clear from Berkeley's writings just how this ‘universal language of the Author of Nature’ is to be interpreted. This paper discusses the nature of the theory of sense perception as language, together with its metaphysical and theological motivations, then (...) proceeds to develop an account of the semantics of the perceptual language, using Berkeley's theory of reference for human language as a guide.

This paper looks at the history of the problem of individuation from Plato to Whitehead. Part I takes as its point of departure Reiner Wiehl’s interpretation of the different meanings of “abstract” in the metaphysics of Alfred North Whitehead and arrives at a corresponding taxonomy of different ways things can be called concrete. Part II compares the way philosophers in different periods understand the relation between thought and intuition. The view mostly associated with ancient philosophy is that thought (...) and sense-perception target different kinds of objects. The view mostly associated with modern philosophy (although it was introduced by the Stoics) is that thought and sense-perception are different ways of targeting the same objects. These differences have specific consequences for theories of individuation, which are assessed historically in Part III and then applied to Whitehead’s difficult texts in part IV. (shrink)

At a time when bioethical issues are at the top of public and political agendas, there is a renewed interest in representations of the embryo in various religious traditions. One of the major traditions that have contributed to Western representations of the embryo is the Jewish tradition. This tradition poses some difficulties that may deter scholars, but also presents some invaluable advantages. These derive from two components, the search for limits and narrativity, both of which are directly connected with the (...) manner in which Jewish tradition was constructed in Antiquity. The article accomplishes three goals: • To introduce some central elements in ancient Rabbinic literature on the subject of the embryo and its representation; • To present this body of literature as clearly as possible, noting some of the difficulties encountered by scholars who engage in its study; • To explain how the literature’s textuality came about, examining the particular sociopolitical circumstances of Judaism at that time, including the reasons for the delay in the production of scientific texts, transmitted as such, as compared to other philosophical or religious traditions. The claim is that these circumstances engendered a tradition peculiarly relevant for the study and teaching of medical ethics today. (shrink)

Religious faith may manifest itself, among other things, as a mode of seeing the ordinary world, which invests that world imaginatively (or inspiredly) with an unseen depth of divine intention and spiritual significance. While such seeing may well be truthful, it is also unavoidably constructive, involving the imagination in its philosophical sense of the capacity to organize underdetermined or ambiguous sense date into a whole or gestalt. One of the characteristic ways in which biblical narratives inspire and teach is by (...) renewing their characters’ and readers’ imagination. The texts do so not inexorably but in a similar way as (other) works of art. This paper therefore investigates the ways in which works of art engage and develop the imagination, and thereby enable renewed perceptual and cognitive engagement with the world. The paper introduces predictive processing as a helpful psychological theory for analyzing this dynamic, and outlines questions for further research. (shrink)

This is an essay on perception and its objects in the Timaeus. Two features of this work are noteworthy. First, the emphasis throughout is on Timaeus' views and not Plato's. Second, I show how broader aspects of Timaeus' cosmology are directly relevant to his philosophy of perception.
