In this thesis, I present an account of the development of early Greek epistemology, according to which Protagoras' measure doctrine, and his argument from conflicting appearances, was the starting point for work on perception and knowledge by Plato in the Theaetetus, Aristotle in Metaphysics IV and Democritus. In Chapter One, I argue against the assumption that Protagoras' Aletheia contained a philosophical theory. It was probably not a treatise, but a virtuoso show-piece, with the aim of "knocking down" views according (...) to which truth is only known by gods, and, with difficulty, by privileged humans--namely, philosophers. For this, it need not have contained more than some well-chosen examples of perceptual and value beliefs, and arguments that one cannot decide which are true. In Chapter Two, I argue that Democritus should be seen as Protagoras' heir. Democritus argued Protagoras' general claim is self-refuting, but thought he was right about perceptual appearances. In Confirmations, he defended the senses, attributing to them knowledge and "power of proof." However, his theory led to an ancestor of the primary/secondary quality distinction, and this threatened to undermine the theory itself because of implications--that one can only know how things appear and not how things are by nature--which were later taken up in Pyrrhonist skepticism. In Chapter Three, I present a reading of the Secret Doctrine in Plato's Theaetetus as a defense and diagnosis of Protagoras' claim, in particular, an explanation of the global relativization which Protagoras' claim seems to recommend. This reading is meant to avoid the well-known difficulties concerning the prevailing interpretation of Protagoras' "Secret Doctrine" as a flux doctrine. I also argue that Plato developed the Secret Doctrine with Democritus in mind. In Chapter Four, I argue that Plato's "self-refutation argument" is aimed at relativism, but not relativism about truth. The latter, which Aristotle dismisses as eristical, is a position Protagoras can take, but Plato's argument works against it as well. In Chapter Five, I examine why Aristotle seems to treat Protagoras in Metaphysics IV as being committed to a denial of the principle of non-contradiction. (shrink)

Can the intellect or the intellectual faculty be its own object of thought, or can it not think or apprehend itself? This book explores the ancient treatments of the question of self-intellection - an important theme in ancient epistemology and of considerable interest to later philosophical thought. The manner in which the ancients dealt with the intellect apprehending itself, took them into both the metaphysical and epistemological domains with reflections on questions of thinking, identity and causality. Ian (...) Crystal traces the origins from which the concept of self-intellection springs, by examining Plato's account of the epistemic subject and the emergence of self-intellection through the Aristotelian account, before the final part of the book explores the problem of how the intellect apprehends itself, and its resolution including Plotinus' reformulation and the dilemma raised by Sextus Empiricus. Crystal concludes that Plotinus recasts the metaphysical structures of Plato and Aristotle in such a way that he casts the concept of self-intellection in an entirely new light and offers a solution to the problem.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.4 (2004) 489-490 [Access article in PDF] Ian M. Crystal. Self-Intellection and its Epistemological Origins in Ancient Greek Thought. Aldershot, England: Ashgate Publishing, 2002. Pp. x + 220. Cloth, $79.95. In this excellent re-working of his King's College Ph.D. thesis, Ian Crystal presents an account of the problem of self-intellection in Greek philosophy from Parmenides through Plotinus. The problem, (...) at least as it appears in ancient Greek philosophy, is connected to the way in which a faculty of soul relates to its proper object. For example, the proper object of the visual faculty is light, that of the auditory faculty sound, and it is the difference in kind between these proper objects that requires different faculties of soul in any account of how it is that we come to grasp the two different kinds of sensory data. Reason is itself a faculty of soul that is supposed to correspond to objects of cognition, but since it is possible to grasp, cognitively, the structure of this faculty the question arises: May this faculty function as its own object? The question is famously answered in the affirmative in Aristotle's treatise De anima at 430a2-5 on the grounds that any immaterial object of cognition is identical to thought itself (epi men gar tôn aneu hulês to auto esti to nooun kai to nooumenon).While this may seem like a peculiarly Aristotelian analysis of cognition (relying, as it does, on Aristotle's distinction between matter and form and his rather cryptic claim that the faculties of soul are actually what their proper objects are potentially), Crystal traces the idea both backwards and forwards in time, rooting the problem in Parmenides' general account of faculties of soul and tracing it through Plotinus's sophisticated account of noetic intellect, with visits along the way not only with Aristotle but Plato and the Stoics as well.The book is divided into three parts. In the first ("The Epistemological Origins") Crystal examines the evolution of the philosophical analysis of cognition from Parmenides through Plato. Parmenides, on this account, was the first to offer anything like a philosophical treatment of intellect (Greek nous). In particular, Parmenides distinguishes between a faculty of intellection and an object of that faculty. Plato, consciously working in the Parmenidean tradition, further analyses mind into its faculties and their proper objects but also gives a more detailed analysis of the epistemological subject. Specifically, Plato's treatment of the faculty in the Theaetetus provides an account of the structure of our cognitive faculty and how that structure relates to the metaphysics of the external world. It is here that Crystal recognizes the emergence of a linguistic component in the epistemic subject's cognitive activity (101; cf. Theaetetus189e6-190a6).Part II ("The Emergence of Self-Intellection") consists of a single chapter in which Crystal reads Aristotle's treatment of self-intellection in the De anima as "Aristotle's epistemological response to Plato." Since self-intellection per se really only emerges for the first time in the De anima, this chapter is in some sense the meatiest part of the book. We are given first a careful treatment of Aristotle's account of perception in DA3.2, affection in DA2.5 and De generatione et corruptione1.7, and the central problem of self-consciousness in DA3.2. The argument moves quickly here but Crystal's analysis is precise and clear. Next comes the analysis of the cognitive structure of intellect itself in DA3.4 and Crystal's account of how Aristotle's two aporiai (How can intellect be both a passive affection and something simple and impassive; and Is intellect itself an intelligible object) are responses to Plato's account of cognition at Theaetetus197c1-200d4 (the Aviary passage) on the one hand and to the general lack of an account of intelligible objects in the Theaetetus on the [End Page 489] other. On Crystal's account, Aristotle improves on Plato in the sense... (shrink)

This study provides a unified framework within which to view the development of pre-Socratic thought. It points out three aspects of Xenophanes' scepticism, and shows how Heraclitus responded to each. Key issues concerning psyche and logos are summarized and an attempt is made to settle certain long-standing debates concerning them.

It will be shown in this article that an ontological approach for some problems related to the interpretation of Quantum Mechanics could emerge from a re-evaluation of the main paradox of early Greek thought: the paradox of Being and non-Being, and the solutions presented to it by Plato and Aristotle. More well known are the derivative paradoxes of Zeno: the paradox of motion and the paradox of the One and the Many. They stem from what was perceived by (...) classical philosophy to be the fundamental enigma for thinking about the world: the seemingly contradictory results that followed from the co-incidence of being and non-being in the world of change and motion as we experience it, and the experience of absolute existence here and now. The most clear expression of both stances can be found, again following classical thought, in the thinking of Heraclitus of Ephesus and Parmenides of Elea. The problem put forward by these paradoxes reduces for both Plato and Aristotle to the possibility of the existence of stable objects as a necessary condition for knowledge. Hence the primarily ontological nature of the solutions they proposed: Plato's Theory of Forms and Aristotle's metaphysics and logic. Plato's and Aristotle's systems are argued here to do on the ontological level essentially the same: to introduce stability in the world by introducing the notion of a separable, stable object, for which a principle of contradiction is valid: an object cannot be and not-be at the same place at the same time. So it becomes possible to forbid contradiction on an epistemological level, and thus to guarantee the certainty of knowledge that seemed to be threatened before. After leaving Aristotelian metaphysics, early modern science had to cope with these problems: it did so by introducing "space" as the seat of stability, and "time" as the theater of motion. But the ontological structure present in this solution remained the same. Therefore the fundamental notion `separable system', related to the notions observation and measurement, themselves related to the modern concepts of space and time, appears to be intrinsically problematic, because it is inextricably connected to classical logic on the ontological level. We see therefore the problems dealt with by quantum logic not as merely formal, and the problem of `non-locality' as related to it, indicating the need to re-think the notions `system', `entity', as well as the implications of the operation `measurement', which is seen here as an application of classical logic on the material world.

The idea that Western philosophy is a footnote to Plato is simplistic and inaccurate. Much of modern and contemporary epistemology owes a debt not so much to Platonism or Aristotelianism as to their antithesis: scepticism. Recent discussions in the history of philosophy have sparked a great deal of interest in the ancient sceptics, but until now they have been misunderstood and the significance of their philosophy not fully appreciated.

This volume deals with Epistemology. The period from the sixth century BC to the second and third centuries AD was one of the most fertile for the theory of knowledge, and the range of 'epistemic states' explored in the ancient texts is much wider than those to be found in contemporary discussions of epistemology or cognition. Greek philosophers approached these problems in a great variety of ways, from the extreme relativism of Protagoras to the scepticism of the Pyrrhonists, and (...) the contributors demonstrate both the familiarity and novelty of this range of views in their critical essays.

This book proposes a reexamination of ancient skepticism with the purpose of both throwing new light on ancient skepticism and contributing to modern epistemological debate. The author hopes to achieve these goals by approaching the ancient texts with a more developed philosophical viewpoint than is found in much historical scholarship, and by showing how the account of ancient skepticism thus achieved is philosophically superior in various ways to modern versions of skepticism. He interprets ancient skepticism as being essentially directed (...) against "realist truth," that is, against the theory that "a claim is true if it corresponds to an objective world that exists independently of the mind". Ancient skepticism is therefore antirealist: it is a mitigated form of skepticism which admits an antirealist conception of truth, "arguing that our beliefs are necessarily relative to human nature and perception, the culture we live in, philosophical commitments, and so on". Ancient skeptics are thus much nearer to modern antirealists than would be the case if their skepticism were unmitigated, as is frequently claimed in modern work on ancient skepticism. Interpreted as antirealism, ancient skepticism turns out to present certain philosophical advantages as compared to modern forms of antirealism. (shrink)

This paper investigates the concept of aletheia in ancient philosophy from the pre-Socratics until Aristotle. The meaning of aletheia in archaic Greek is taken as the starting point. It is followed by remarks about the concept of truth in the Seven Sages. The author discusses this concept as it appears in views and works of philosophers and historians. A special section is devoted to the epistemological and ontological understanding of truth. On this occasion, influential views of Heidegger are (...) examined. The paper is concluded by a review of various meanings of truth in Aristotle. (shrink)

The focus of this essay is on Xenophanes’ criticism of anthropomorphic representation of the gods, famously sounding like a declaration of war against a constituent part of the Greek religion, and adopting terms and a tone that are unequalled amongst “pre-Socratic” authors for their directness and explicitness. While the main features of Xenophanes’ polemic are well known thanks to some of the most studied fragments of the pre-Socratic tradition, a different line of enquiry from the usual one is attempted (...) by considering the multi-layered background of the religious beliefs revolving around the idea that the gods have human form as outlined in the tradition of epic poetry or represented in cult statues: in the light of this consideration Xenophanes’ text can take on some new characteristics. In the second part of the article, emphasis is put on the importance of the correlation Xenophanes established between the issue of the appearance of the gods and that of the certainty of knowledge, in terms that have exerted tremendous influence on later thought, most notably on Plato in the Timaeus.

The ancient world witnessed a meaningful transition in the conception of human thought and belief. What some have called the “discovery” of the mind can also be understood as a release from dependence on oracular wisdom and mythological explanation, made possible by the invention of more reliable and democratic methods for discovering and explaining truths. During roughly the same epoch, Hellenic sport distinguished itself by developing objective mechanisms for selecting single winners from varied pools of contestants. Is there a (...) connection? Following the general thesis that sport is an expression of thehuman desire to know, this paper will explore the epistemological nature of the earliest forms Hellenic athletics. I begin by interpreting the funeral games depicted in Homer’s Iliad as an unbiased, publicly monitored means for settling questions of social honor. I then consider the ancient Olympic games, arguing that their religious foundations motivated a new focus on objective and reliable methods for selecting single winners who could be symbolically sacrificed to the god. In both manifestations, athletic games are used to objectively answer important questions about merit. Eventually, competitive methods of truth‐seeking would become commonplace in Western thought. By examining early the origins of Greek sport in this light, however, Olympia may be identified as a key source of epistemological testing methods, and sport itself may be characterized fundamentally as a search for knowledge.

This essay explores the interconnections among the humanistic epistemological theories of Ficino, Pomponazzi and Cusanus apparent in the context of their reception of ancient Greek and medieval philosophy, especially Plato's Theaetetus and Aristotle's De anima. It shows that preceding the opposition between the Platonic scheme of knowledge favored by Ficino and the Aristotelian account of the intellect championed by Pomponazzi, Cusanus attempted to articulate the nature of the mind as such which all modes of knowledge presuppose. Central to (...) this project is his work De coniecturis with its theory of the unity of the divine, reason, the understanding and the body, by means of which Cusanus undertook to show how all modes of knowledge are immanent in the mind even as knowledge itself is a process. Concluding critical remarks expound upon the principal significance for knowledge of the thought of nothing, which fundamentally defines the relation to self and other and therewith the horizon of the possible truth of knowledge.

Traces the development of the idea of experience (Greek peira, empeiria) in Greek thought, from its origins in the Presocratics, through Aristotle and subsequent Peripatetics (Theophrastus, Alexander of Aphrodisias), to Galen. Particular emphasis is placed on the ideas of the medical school of the Empirics, who based their theory and practice on experience and memory. This experience-based epistemology can be traced back to the “epistemic modesty” characteristic of Archaic Greek thought. Some passages in Avicenna, redolent (...) of Sufism, which react to perceived shortcomings in the Aristotelian theory of cognition and demonstration (especially the ineffability of individuals) may have been influenced by the medical Empirist tradition. This emphasis on experience, shared by Archaic Greek thought, medical Empirism, and by certain aspects of Buddhism, may have influenced Islamic Sufism, and hence the thought of Avicenna and his successors.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to Early Greek PhilosophyPatricia CurdA. A. Long, editor. The Cambridge Companion to Early Greek Philosophy. Cambridge: Cambridge University Press, 1999. Pp. xxxii + 427. Cloth, $54.95. Paper, $19.95.The Cambridge Companions are designed both to introduce and to survey, aims that anyone who teaches introductory courses knows are not fully compatible. The Cambridge Companion to Early Greek Philosophy is successful because its contributors (...) have kept to a uniform tone of mostly introduction, with some reference to recent developments and controversies in the field. There are sixteen essays, with a judicious mix of chapters on particular figures and on general topics.A. A. Long provides a helpful introduction, discussing the problems of dealing with the fragmentary evidence for these philosophers, and giving an account of the nature and scope of early Greek thought. (He also argues—not entirely persuasively—that we should give up the nineteenth century name "Presocratics" for these thinkers.) Jaap Mansfeld explains the problems of sources and doxography (the chapter is quite compressed and could be rather overwhelming for the newcomer to the area), while Keimpe Algra surveys Ionian cosmology. Carl Huffman provides a masterful discussion of early Pythagoreanism, attempting to sort out what we can and cannot be justified in claiming about Pre-Platonic Pythagoreanism. The chapters on individual thinkers mostly provide systematic overviews. Edward Hussey contributes an exemplary chapter on Heraclitus, and David Sedley one on Parmenides and Melissus (it is good to see Melissus treated seriously), with Richard McKirahan weighing in on Zeno (mostly on the paradoxes of motion but with some attention to the arguments against plurality). The discussions of individual Presocratics are rounded out with Daniel Graham's treatment of Empedocles' and Anaxagoras' responses to Parmenides, and C. C. W. Taylor on the Atomists. Sarah Broadie considers rational theology and James Lesher early Greek epistemology, while André Laks surveys ancient theories of soul, sensation, and thought. Paul Woodruff and Fernanda Decleva Caizzi provide chapters on the Sophists, the former discussing Protagoras and Gorgias, the latter, Protagoras and Antiphon. Mario Vegetti undertakes an examination of the notion of causation in early Greek thought, and Diskin Clay explores the poetics of the Presocratic philosophers. The book opens with short discussions—three paragraphs devoted to life, sources, and works for each of the thinkers who figure in the period (in alphabetical rather than even roughly chronological order), a chronological chart, and a map. There is a large and useful—though necessarily selective— bibliography (supplemented in the notes to some chapters by references to articles that are not included in the main bibliography), an index locorum, and an index of names and subjects that [End Page 429] includes modern scholars "only if their views are cited in the main text or discussed in footnotes" (which makes it difficult to use in tracking down references). Unfortunately, as in all the Cambridge Companions, notes are at the end of articles rather than at the foot of the page, making necessary a fair bit of flipping while reading.How well do the contributors succeed in meeting the needs of the intended readers of the series? For the most part, very well; the novice reader will find this an accessible guide to Early Greek philosophy. The various discussions are solid and well-informed, and the authors have indicated issues and interpretations that are controversial (for example, Taylor takes time to consider objections to his earlier criticism of Vlastos on the connection between atomistic metaphysics and ethics, and Hussey is careful to note the traditional flashpoints of disagreement in Heraclitus interpretation). It is also good that some of the Sophists are included (it is worth considering how viable the traditional distinction between the Sophists and the Philosophers really is), and inclusion of both the medical tradition and the issue of poetics is very welcome. Further chapters considering in more detail the cosmologies of post-Milesians (including Parmenides) and on the philosophical uses made of the early Greek thinkers by Plato and Aristotle would have rounded things out, but these would have made an already big book bigger. As perhaps befits an introductory survey, most of the interpretations lean to the traditional - someone looking for... (shrink)

This collection of essays, by Reding, in the emergent field of Sino-Hellenic studies, explores the neglected inchoative strains of rational thought in ancient China and compares them to similar themes in ancient Greek thought, right at the beginnings of philosophy in both cultures. Reding develops and defends the bold hypothesis that Greek and Chinese rational thinking are one and the same phenomenon. Rather than stressing the extreme differences between these two cultures - as most other writings (...) on these subjects - Reding looks for the parameters that have to be restored to see the similarities. Reding maintains that philosophy is like an unknown continent discovered simultaneously in both China and Greece, but from different starting-points. The book comprises seven essays moving thematically from conceptual analysis, logic and categories to epistemology and ontology, with an incursion in the field of comparative metaphorology. One of the book's main concerns is a systematic examination of the problem of linguistic relativism through many detailed examples. (shrink)

It proceeds (...) to examine to what extent they are really in contrast to Greek philosophy, and it ends up with a reconsideration of the relation of these two features. (shrink)

Scientific thought and its burdens is a book to search for the ways in which science has been understood in history and the way we conceive it today. It argues that every human phenomenon has certain mental frameworks through which it is manifested. Then it raises the question: through which mental frameworks is science manifested? First of all, science is a cognitive activity and as such it is an attempt to acquire knowledge of certain objects or phenomena around us. (...) In that case, it must have an epistemological framework, which is developed in this book as the epistemology of science; then, it is an activity carried out by a community of scholars and their students in an uninterrupted chain of tradition. This gives us the sociological framework. Based on these fundamental frameworks, i.e. the cognitive and sociological approach, the concept of science is defined. Due to the lack of a satisfactory epistemological and sociological framework, taken together, many crucial concepts, such as scientific process, scientific consciousness and worldview, concerning the rise and development of science within a civilization has not adequately been explained. This book thus brings a fresh understanding of sociological concepts concerning science, such as scientific community and tradition. Sufficient material is brought in from the history of science unfolding itself within three civilizations; Greek, Islamic and Western, in order to vindicate the framework in which scientific thought in these communities emerged.

The Greek philosopher Aristotle continued the tradition of his predecessors, Socrates, the Sophists, and Plato, who for the first time had made man the centre of philosophical reflection. However, Aristotle did not limit his thought to man alone; man, situated at the top of the Great Chain of Being, is an integral part of the encompassing nature. In his Treatise on the Soul (De Anima) Aristotle’s argument concerning the soul’s knowledge-generating faculties, in particular the dialogue with his predecessors, (...) resembles in many respects the philosophical debate on the pramāṇas, ‘the valid ways of cognition’, which informed the classical Indian schools of thought. In Aristotle’s De Anima we possess a unique, coherent treatise that deals exhaustively with ‘valid ways of cognition’, a treatise that kept its prominent position until the Scientific Revolution of the 16/17th century. This book focuses on the concept of the hylomorphic soul and the process by which it actuates cognition, that means it is concerned with Aristotle’s epistemology. From his conception of the soul or psychẽ as the entelexeia of the body arises the ‘noetic problem’. The idea of a human mind, nous, that takes part in a supra-individual, semi-divine world of knowledge (epistẽmẽ) is apparently at odds with the basic principles of Aristotle’s philosophy. When the Philosopher avows that the mind is ‘separable’ in its true realization, the question is how it can still be part of the human soul. It is argued that the so-called ‘susceptible mind’ (νοῦς παθητικός) and its actual operation are two aspects of one and the same nous: the potency of the human mind to accommodate forms or ideas distinguishes it fundamentally from the divine ‘thinking of thinking’, the eternal, immutable state of the celestial mind.

The doctrines of the Hellenistic Schools - Epicureans, Stoics, and Sceptics - are known to have had a formative influence on later thought, but because the primary sources are lost, they have to be reconstructed from later reports.

We suffer from genealogical anxiety when we worry that the contingent origins of our representations, once revealed, will somehow undermine or cast doubt on those representations. Is such anxiety ever rational? Many have apparently thought so, from pre-Socratic critics of Greek theology to contemporary evolutionary debunkers of morality. One strategy for vindicating critical genealogies is to see them as undermining the epistemic standing of our representations—the justification of our beliefs, the aptness of our concepts, and so on. I (...) argue that this strategy is not as promising as it might first seem. Instead, I suggest that critical genealogies can wield a sort of meta-epistemic power; in so far as we wish to resist the genealogical critic, we are under pressure to see ourselves as the beneficiaries of a certain kind of good luck: what I call genealogical luck. But there is also a resolutely non-epistemic way of understanding the power of critical genealogies, one that is essential, I argue, for understanding the genealogical projects of various theorists, including Nietzsche and Catharine MacKinnon. For critical genealogies can reveal what it is that our representations do—and what we, in turn, might do with them. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 87 Rationalism in Greek Philosophy. By George Boas. (Baltimore: The Johns Hopkins Press, 1961. Pp. xii + 488. $7.50.) This is an interesting and provocative work. It is not, as Boas warns his readers, a history of Greek philosophy in general. It is concerned, rather, with several large topics which the author uses to explicate the general theme of Greek rationalism. The topics chosen (...) are: the distinction between appearance and reality, the methods used to draw this distinction, the conception of human life, and ethics. The treatment of these topics, so central and important in the history of Greek thought, results in a work of very considerable scope. In temporal span also the work is substantial, for it studies and interprets these selected topics from the Pre-Socratics through the Neo-Platonists. The work is complex. Each chapter undertakes to resolve controversial questions both of textual and philosophical criticism. Boas's judgment in these matters is often insightful, always fresh and stimulating. In a difficult and compressed Preface, Boas explains what he understands by rationalism. Rationalism is described as a "systematic study" of accepted premises, which means, in part, the testing of the implications of accepted premises for logical consistency. A premise is, ideally, a generalization from experience, for "... general laws... are wanted in science and philosophy" (p. vii). But premises may sometimes be derivative from such sources as common sense or intuition. Whatever their source, premises and their implications must run the test of consistency and, in addition provide a "... verifiable account of an important set of facts" (p. x). Quite apart from the troubling remark about "general laws," two elements are mentioned in the Preface which constitute what Boas intends by "rationalism." One wonders at the beginning bow these methodological criteria will serve in the interpretation of Greek rationalism. Boas, in practice, uses a much more generous conception of rationalism as a method than that proposed in the Pre[ace.Sometimes rationalism stands for the appeal to reason or experience or both in contrast to the appeal to authority and revelation. It is toward the end of the book that one finds perhaps the best statement of rationalism as a method which has guided this study. Professor Boas writes, reflecting back on the course ol Greek thought: We know too little about the Milesians and the Pythagoreans to say more than that they translated the ancient myths of cosmic birth and decay into rational language. But when we come to the figures of lteraclitus, Parmenides, and Democritus, we meet with that independence of mind which seems to us characteristic of the great scientific investigators. The double role of reason, that of criticism and that of construction, was played wholeheartedly by them, and apparently the mere fact that a belief was traditional did not give it special plausibility. The same may be said of both Plato and Aristotle (p. ~54). It dearly requires some conception such as this, in contrast to that of the Preface, to understand, on the methodological side, Boas's strong claims that Plato and Aristotle are "... the greatest rationalists in the history of philosophy..." and that Plato is the "major defender of rationalism" (p. 128). One needs, however, much more than just the commitment of the "double role of reason" to understand these claims about Plato and Aristotle. Rationalism is also used to denote a number of philosophical doctrines, some of which Plato and Aristotle shared in common. It is carefully argued, for instance, that both Plato and Aristotle are committed to the epistemological view that reason alone is the source of knowledge in the strict sense, a doctrine, which in the case of Aristotle, is sometimes obscured. To this 88 HISTORY OF PHILOSOPHY basic feature of rationalism Boas adds the following: "The inability, or perhap the unwillingness, to conceive of anything transient as real is at the heart of the rationalist tradition..." (p. 184). It is this notion of rationalism as certain substantive philosophical doctrines which often dominates Boas's account of this central theme in the history of Greek thought. It becomes especially clear in an interesting chapter on Aristotle that it is adherence to certain philosophical doctrines rather than adherence... (shrink)

An overview is provided of how the concept of the thought experiment has developed and changed for the natural sciences in the course of the 20th century. First, we discuss the existing definitions of the term 'thought experiment' and the origin of the thought experimentation method, identifying it in Greek Presocratics epoch. Second, only in the end of the 19th century showed up the first systematic enquiry on thought experiments by Ernst Mach's work. After the (...) Mach's work, a negative attitude towards thought experiments came in the beginning of the 20th century, which went on until the Thomas Kuhn's and Karl Popper's work on thought experiments. Only from the mid-1980s did thought experiments begin to be considered relevant to scientific enterprise. Finally, we show the existing empirical and 'functional' theories which have developed about the nature and purpose of thought experiments. (shrink)

The essays in this volume treat a wide variety of fundamental topics and problems in ancient Greek philosophy. The scope of the section on pre-Socratic thought ranges over the views which these thinkers have on such areas of concern as religion, natural philosophy and science, cosmic periods, the nature of elements, theory of names, the concept of plurality, and the philosophy of mind. The essays dealing with the Platonic dialogues examine with unusual care a great number of central (...) themes and discuss them in considerable depth: problems in language and logic, myth, reason, hypothesis, eros, friendship, reason, morality, society, art, the nature of soul, and immortality. In addition, they offer fresh discussions on a number of basic morphological, methodological, and philological issues related to philosophical arguments and introduce new aspects for a critical reexamination of controversies surrounding the doctrines and the authenticity of certain Platonic works. The essays on the philosophy of Aristotle are closely reasoned analyses of such basic themes as the universality of the sensible, the nature of kinesis, the problem of future contingencies, the meaning of qualitative change, the doctrine of phantasia, the essence of intelligence, and the metaphysical foundations for the ethical life. The essays on post-Aristotelian developments in ancient philosophy offer challenging and well-documented discussions on topics in the history of ancient logic, categorical thought, the ethical doctrines of ancient Scepticism, epistemological issues in the physical theory of the Epicureans, and basic concepts in the metaphysics of the neo-platonists.

The article is devoted to the analysis of ontological and epistemological models of the transcendent and transcendental in ancient philosophy, which allows us to understand the genesis and foundations of the main variants of metaphysics in classical thought. In general, constructions of ancient Greek thought are characterized by the understanding of the transcendent as "other" being, the higher sphere of the "cosmos of nature", which has specific spatio-temporal properties, which is outside the immanent world of man. (...) Ontological terms, the Cosmos was subdivided into earthly being, in which a man lives, and being "beyond", inaccessible to a man because of his bodily and vital limitations. In epistemological terms the transcendent was considered incomprehensible for sensory cognition, but accessible for cognition of the speculative, although not in full. The metaphysical model of the transcendental created by antiquity did not provide for the existence of an independent "human cosmos" isolated from the external world. The main task of the transcendental method was to determine the conditions by which it is possible to think of the data of empirical observations. (shrink)

Prior Analytics by the Greek philosopher Aristotle and Laws of Thought by the English mathematician George Boole are the two most important surviving original logical works from before the advent of modern logic. This article has a single goal: to compare Aristotle's system with the system that Boole constructed over twenty-two centuries later intending to extend and perfect what Aristotle had started. This comparison merits an article itself. Accordingly, this article does not discuss many other historically and philosophically (...) important aspects of Boole's book, e.g. his confused attempt to apply differential calculus to logic, his misguided effort to make his system of ‘class logic’ serve as a kind of ‘truth-functional logic’, his now almost forgotten foray into probability theory, or his blindness to the fact that a truth-functional combination of equations that follows from a given truth-functional combination of equations need not follow truth-functionally. One of the main conclusions is that Boole's contribution widened logic and changed its nature to such an extent that he fully deserves to share with Aristotle the status of being a founding figure in logic. By setting forth in clear and systematic fashion the basic methods for establishing validity and for establishing invalidity, Aristotle became the founder of logic as formal epistemology. By making the first unmistakable steps toward opening logic to the study of ‘laws of thought’—tautologies and laws such as excluded middle and non-contradiction—Boole became the founder of logic as formal ontology.… using mathematical methods … has led to more knowledge about logic in one century than had been obtained from the death of Aristotle up to … when Boole's masterpiece was published.Paul Rosenbloom 1950.

The ancient world witnessed a meaningful transition in the conception of human thought and belief. What some have called the “discovery” of the mind can also be understood as a release from dependence on oracular wisdom and mythological explanation, made possible by the invention of more reliable and democratic methods for discovering and explaining truths. During roughly the same epoch, Hellenic sport distinguished itself by developing objective mechanisms for selecting single winners from varied pools of contestants. Is there a (...) connection? Following the general thesis that sport is an expression of thehuman desire to know, this paper will explore the epistemological nature of the earliest forms Hellenic athletics. I begin by interpreting the funeral games depicted in Homer’s Iliad as an unbiased, publicly monitored means for settling questions of social honor. I then consider the ancient Olympic games, arguing that their religious foundations motivated a new focus on objective and reliable methods for selecting single winners who could be symbolically sacrificed to the god. In both manifestations, athletic games are used to objectively answer important questions about merit. Eventually, competitive methods of truth‐seeking would become commonplace in Western thought. By examining early the origins of Greek sport in this light, however, Olympia may be identified as a key source of epistemological testing methods, and sport itself may be characterized fundamentally as a search for knowledge.

The first segment starts with a definition of two dimensions of the concept of rule of law; related to the notion of sovereignty and as a concept to control arbitrariness on the part of the ruler. The segment proceeds to give a historical account of the notion and the different stages of its epistemological configuration, from the ancient Greek notion of Eunomia and its incompatibility with the popular rule to the current notion, where the rule of law has (...) become fused with democracy and human rights. The first segment also focuses on the relation between the concept of the rule of law and other principles, such as proportionality, neutrality, and effectiveness. The second segment of the paper analyses the phenomenon of juridification of the rule of law in international treaties and domestic constitutions. It pays particular attention to the role that constitutional accommodation plays in the process of rationalization of the rule of law as a prerequisite to its idealization and mystification. It analyses the reason why this principle is an essential feature of the constitutionalism despite the inner plurality of legal systems. The next aspect, analysed in the third segment of this paper, is the messianic use of the concept of the rule of law. The paper performs a critical definition of messianic, covering a theological perspective and the different theories and concepts that go hand in hand with the idea of the Messiah, such as the “coming”, prophetical and apocalyptical messianism, the phenomena of eschatology, expiation and redemption pictured in Judaism. The segment also covers the secular transplantation of the messianic thought. The last segment is a conclusion returning to the themes identified in the paper and summarises how the messianic thought is applied in the realm of the rule of law. (shrink)

Explores the development of Chinese thought, highlighting its concern with questions of coherence. Providing a bracing expansion of horizons, this book displays the unsuspected range of human thinking on the most basic categories of experience. The way in which early Chinese thinkers approached concepts such as one and many, sameness and difference, self and other, and internal and external stand in stark contrast to the way parallel concepts entrenched in much of modern thinking developed in Greek and European (...) thought. Brook Ziporyn traces the distinctive and surprising philosophical journeys found in the works of the formative Confucian and Daoist thinkers back to a prevailing set of assumptions that tends to see questions of identity, value, and knowledge—the subject matter of ontology, ethics, and epistemology in other traditions—as all ultimately relating to questions about coherence in one form or another. Mere awareness of how many different ways human beings can think and have thought about these categories is itself a game changer for our own attitudes toward what is thinkable for us. The actual inhabitation and mastery of these alternative modes of thinking is an even greater adventure in intellectual and experiential expansion. Brook Ziporyn is Professor of Chinese Philosophy, Religion, and Comparative Thought at the University of Chicago Divinity School and Visiting Professor of Philosophy at the National University of Singapore. His books include The Penumbra Unbound: The Neo-Taoist Philosophy of Guo Xiang, also published by SUNY Press. (shrink)

Since the early 20th century, two new disciplines emerged in the tradition of analytic philosophy: meta-ethics and political epistemology. Nevertheless, debates on such questions go back to the ancient Greeks and, in particular, to the debates between Plato and Protagoras. This article elucidates the controversy between Plato and the influential sophist Protagoras from the perspective of contemporary meta-ethics and political epistemology. It argues that the main motivation of Plato’s philosophical endeavors is to overcome Protagoras’s skeptical claims that no moral facts (...) and no moral knowledge applicable to political issues exist. The paper defends the thesis that there exists a deep disagreement between Protagoras and Plato on the existence of moral facts and moral knowledge. A deep disagreement is a disagreement that cannot be resolved through the use of reasons and arguments. Applying the foundationalist approach Robert J. Fogelin proposes in his seminal paper “The Logic of Deep Disagreements”, this article argues that the deep disagreement between Protagoras and Plato exists because their political thought is based on “underlying principles” that clash. While Plato’s political philosophy rests on his religious and theological convictions, the political thought of Protagoras is based on his skepticism, relativism, and agnosticism. (shrink)

From Greco-Roman antiquity through to European enlightenment, philosophy and religious thought were inseparably interwoven. This book explores intellectual worlds of Abrahamic religious traditions, their approaches to scriptural hermeneutics, and their interaction over many centuries on common ground of inheritance of classical Greek philosophy.

This article explores Presocratic epistemology, arguing that divine revelation is replaced as a warrant for knowledge with naturalistic accounts of how and what we humans can know; thus replacing earlier Greek pessimism about knowledge with a more optimistic outlook that allows for human discovery of the truth. A review of the relevant fragments and testimonia shows that Xenophanes, Alcmaeon, Heraclitus, and Parmenides—even Pythagoras and Empedocles—all moved some distance away from the older “god-oriented” view of knowledge toward a more secular (...) and optimistic outlook. But to get some sense of the dynamics at work in this transition this article begins, as virtually every account of early Greek thought must begin, with Homer and Hesiod. (shrink)

Each of us is a measure. The project of advocates of change in Plato’s Theaetetus as compared with sophistic thought -/- Summary -/- One of the most intriguing motives in Plato’s Theaetetus is its historical-based division of philosophy, which revolves around the concepts of rest (represented by Parmenides and his disciples) and change (represented by Protagoras, Homer, Empedocles, and Epicharmus). This unique approach gives an opportunity to reconstruct the views of marginalized trend of early Greek philosophy - so (...) called „the sophistic movement”. Paradoxically, previous research shows little interest in sophistic thought as a source of the standpoint of advocates of change („the secret doctrine”). The roots of „the secret doctrine” were investigated in the works of Heraclitus, Aristippus, and Antisthenes or those related to “neoheracliteanism”. However, researchers did not make any significant attempt to confront this concept with the contemporary research on the sophistic movement. The conviction that sophistry was primarily humanistically oriented was one of the main reasons why researches were opposed to the fact that „the secret doctrine” could represent a true expression of Protagoras’ views. This is why J. Burnet and F. M. Cornford in their seminal works assumed that “the secret doctrine” should be attributed to Plato, who simply combined a series of loose statements into one single project. In this work, we argue that the thesis which questions the parallels between the sophists’ interests and the philosophers of nature requires a significant revision. There is ample evidence to suggest that the philosophy of nature was a part of sophists’ research. This is supported by two main arguments. First, the tutors of sophists were philosophers of nature. Second, there are numerous sources that explicitly show sophists’ interest in the physical issues. These sources include anecdotal evidence about the fact that sophists wrote works On nature. There is also information confirming that they deliberated on detailed physical issues. The analogies between the concepts attributed to the advocates of change and our knowledge about sophists from other sources is very wide and contains most elements, which are included in the project of “changeable reality” presented in Theaetetus. The deliberations on the mechanism of perception, which are close to those of flux theory of perception in Theaetetus, are present in the sources referring to Gorgias of Leontinoi, the famous sophist and rhetorician. Also, the second element of “the secret doctrine” that is the metaphysics of flux matches up with what we know about the sophists’ views from other sources. On this basis, one can deduce that – contrary to the tradition which marginalized the role of sophistic considerations on the issue of being and non-being – it was one of the major subjects of sophistic research. Its main point was the criticism of the Eleatic conception of a single and unchangeable being, which also plays a key role in the doctrine of flux in Theaetetus. The epistemological theses which are presented in Theaetetus are borne out in sophistic sources. They include the definition of knowledge as perception, the „Man-measure” formula and a number of principles, which result from these foundational theses. Sophists’ empirical preferences resonate with the theses of the advocates of change in Theaetetus. Special attention that is given to the issues of differences among people, and even to cognitive differences in one person depending on the changeable states to which a person is subject, goes well together with what we know about reciprocal influence between the sophistry and medicine. The consequences of the epistemological conception present in Theaetetus have their equivalents in sophists’ works and other testimonies. An example of these consequences may be the abolition of truth and falsehood or the abolition of contradiction, which finds its expression in the thesis ouk estin antilegein. The analogies also concern reflections on the language itself. The project of the “new language” uses categories, which were developed by sophists. These include the antithesis of nomos and physis. The general intentions of this project reflect Protagoras’ ideas, at least to the extent to which they are known from the sources reporting his thoughts on language. Plato’s Theaetetus can thus be considered a veritable treasury of sophistic motifs. Even though the problem remains unsolved and one is still not able to unambiguously decide about the author of “the secret doctrine”, one can come to a certain conclusion – even if Plato synthesized various doctrines, he must have relied in his project mostly on the elements that he borrowed from sophists. Moreover, the value of reconstructing the project of the advocates of change in Theaetetus does not consist of mere enumeration of sophistic motifs. The dialogue is key to understanding the sophistic movement, whose separate doctrines – for the lack of sources and as a result of centuries-old disregard – are usually treated as rhetorical formulae that are interpreted in many ways and have no philosophical foundations. If it is really the case that the theses attributed to Protagoras in Theaetetus were actually a part or a derivative of Protagoras’ thought, or – speaking more conservatively – if they constitute a synthesis of sophistic thought done by Plato, they could represent philosophical foundations for the most important sophistic theses: the “Man-measure” formula, the ouk estin antilegein principle, the concept of language as a tool, the idea of the relativity of good and the whole practical sphere of sophists’ activity. Contrary to the views of many researchers, we are certain that the representatives of the sophistic movement did not limit themselves only to the application of practical rules, which determined the extent of their educational or rhetorical-political activity. They were capable of creating – indeed, they did create comprehensive projects that embraced the whole thematic scope subject to philosophical reflection. (shrink)

The systematic comparison of Avicenna’s Ilāhiyyāt of the Šifā' with Aristotle’s Metaphysics , accomplished for the first time in the present volume, provides a detailed account of Avicenna’s reworking of the epistemological profile and contents of the Metaphysics and a comprehensive investigation of this latter’s transmission in pre-Avicennian Greek and Arabic philosophy.

Western civilization is over. So begins Jan Zwicky’s trenchant exploration of the root of global cultural and ecological collapse: a way of thinking that is also linked to some of the West’s most noted achievements. The Renaissance merged imperial enterprise with Islamic algebra and recently recovered Greek mathematics to precipitate mechanized industry and resource extraction; these in turn made possible the growth of capitalism, the military-industrial complex, and Big Technology. Despite its self-image as objective, Zwicky argues, the West’s style (...) of thought is not politically neutral, but intensely anthropocentric. It has led those who adopt it to regard the more-than-human world as nothing more than timber licences and drilling sites, where value is not recognized unless it is monetized. Oblivious to context and blind to big-picture thinking, it analyzes, mechanizes, digitizes, and systematizes, while rejecting empathy and compassion as distorting influences. Lyric comprehension, in Zwicky’s view, offers an alternative to this way of thinking, and she provides a wide range of examples. Once upon a Time in the West documents how a narrow epistemological style has left Western thought blind to critical features of reality, and how the terrifying consequences of that blinkered vision are now beginning to unfold.
