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)

In lieu of an abstract, here is a brief excerpt of the content:Semantics in Aristotle’s OrganonMark WheelerVarious contemporary commentators have made conflicting claims about Aristotle’s theory of meaning. Some have claimed that he has a denotational theory of meaning, others that he has an ideational theory of meaning, and yet others that he has confused the denotational and ideational aspects of meaning.1 Recently, Kretzmann and Irwin have presented arguments which, taken together, imply that Aristotle has no theory of meaning.2I think (...) that all of these views are mistaken. Aristotle, I shall argue, is working with a rather sophisticated and coherent theory of meaning incorporating both denotational and ideational components. In section 1, I reconstruct the general theory of linguistic signification presented in De Interpretatione [End Page 191] 16a3–9, a passage which has been the cornerstone of both ancient and contemporary interpretations of Aristotle’s theory of meaning. I develop an interpretation different in important respects from both the standard view and recent alternatives. Aristotle’s general theory emerges as a remarkably flexible account of the relations among linguistic signs, mental images, and real things.3 In section 2, I recast Aristotle’s general theory in contemporary semantic terminology and respond to various arguments purporting to show that Aristotle hasn’t a theory of meaning as these are now understood.1. ARISTOTLE’S GENERAL THEORY OF LINGUISTIC SIGNIFICATIONIn the present section, I develop an interpretation of Aristotle’s explicit, albeit terse, sketch at De Interpretatione 16a3–9 of the fundamental semiotic relations among written marks, spoken sounds, affections of the soul, and things in the world. In so doing, I consider and reject an argument according to which the passage either doesn’t present a general theory of linguistic signification or, if it does, the theory presented is fatally flawed.4 The results of this section are very general but important enough to warrant isolated attention. I argue that, given Int. 16a3–9, Aristotle is committed to the following claims: (1) Written marks are signs of spoken sounds; (2) spoken sounds are, by their very nature, signs of mental images; (3) spoken sounds are, by convention, signs of mental images; (4) the mental images signified by spoken sounds are, by their very nature, signs of real perceptible or intelligible qualities; and (5) the mental images signified by spoken sounds are, by their very nature, signs of real things.5 [End Page 192]Our passage has been the subject of extensive study. Kretzmann has called it “the most influential text in the history of semantics” (3). It is worth quoting in full:Now spoken sounds [ϕωναί] are symbols [σύμβολα] of affections in the soul [ἐν τῇ Ψυχῇ παθημάτων], and written marks [γϱαϕὀμενα] symbols of spoken sounds. And just as written marks [γϱάμματα] are not the same [τά αὐτά] for all men, neither are spoken sounds. But what these are in the first place [πϱώτων] signs [σημει̑α] of—affections of the soul [παθἡματα τῆς Ψυχῆς]—are the same for all; and what these affections are likenesses [ὁμοιώματα] of—real things [πϱάγματα]—are also the same. These matters have been discussed in the work on the soul and do not belong to the present subject.6Traditionally, the passage is taken to present a sketch of Aristotle’s general theory of meaning.7 Standard interpretations run roughly as follows. First, Aristotle lays down three general semantic principles: Written marks signify spoken sounds; spoken sounds signify affections in the soul; and affections in the soul represent things in the world. These principles establish the basic semiotic relations among language, thought, and reality. Second, Aristotle implies (cf. Int. 16a6) that spoken sounds signify in the first place affections in the soul and that, by means of this primary significance, spoken sounds signify in the second place real things.8 I shall call this the ‘Semantic Primacy Thesis. ‘ Third, the affections in the soul with which Aristotle is concerned are thoughts [νοἠματα], and he refers us to book III, chapters 7–8 of the De Anima for further discussion of the nature of these. Lastly, Aristotle is developing a strictly conventionalist theory of linguistic meaning, according to which although all human beings have access to the same affections in the soul and the same real things, different written and spoken languages are used by different communities to signify...

This paper describes a theory of accuracy or approximate truth and applies it to problems in the realist interpretation of scientific theories. It argues not only that realism requires approximate truth, but that an adequate theory of approximation also presupposes some elements of a realist interpretation of theories. The paper distinguishes approximate truth from vagueness, probability and verisimilitude, and applies it to problems of confirmation and deduction from inaccurate premises. Basic results are cited, but details appear elsewhere. Objections are surveyed, (...) including arguments by Miller, Laymon, and Laudan. Comparison is made with Niiniluoto's theory of verisimilitude, and the utility of his theory for realism assessed. (shrink)

Book Gamma of Aristotle’s Metaphysics contains a vigorous defense of the principle of non-contradiction (PNC). A chief part of Aristotle’s strategy is to attack those, such as Heraclitus and Protagoras, who are said to deny the principle. Commentators have found a number of logical and historical problems with Aristotle’s arguments, but none are more troubling than those he deploys against Protagoras. Midway through Gamma 4, and throughout Gamma 5, he represents Protagoras not as simply denying PNC but rather as asserting (...) the contrary of the principle. The latter, the proposition that every thing has every property and its negation, I call the strong denial of PNC. In particular, Aristotle argues that Protagoras is committed to strong denial because of ‘Protagorean’ relativism – the doctrine that if something appears to be the case, then it is the case. This paper provides a reconstruction of Aristotle’s arguments in Gamma 4 and 5, and suggests that the second argument may infact hold against the Protagorean. (shrink)

In "Metaphysics" Gamma 3 Aristotle declares that the philosopher investigates things that are qua things that are and that he therefore should be able to state the firmest principles of everything. The firmest principle of all is identified as the principle of non-contradiction (PNC). The main focus of Gamma 3 is Aristotle's proof for this identification. This paper begins with remarks about Aristotle's notion of the firmness of a principle and then offers an analysis of the firmness proof for PNC. (...) It focuses on some key assumptions of the proof and on the range and force of the proof. Aristotle closes Gamma 3 with the claim that PNC is ultimate in the sense that all other principles somehow rest on it. This, rather controversial, claim is given a defensible reading and shown to be central to the chapter's effort to establish PNC as the firmest principle of all. As such it completes the firmness proof and is not simply an appended remark. (shrink)

Aristotle connects modality and time in ways strange and perplexing to modern readers. In this book the author proposes a new solution to this exegetical problem. Although primarily expository, this work explores topics of central concern for current investigations into causality, time, and change.

Cet ouvrage est désormais à tous égards un classique. Il a assurément, lors de sa première édition en 1939, suscité nombre de réactions critiques à la mesure de la nouveauté réelle d'un travail qui, délaissant les voies et les impasses de la méthode génétique, s'attachait, plutôt que de reconstituer dans sa systématicité prétendue la pensée du Stagirite, à dégager les cadres généraux ou les schèmes qui structurent effectivement une recherche se faisant. En se sens, il s'agissait bien d'étudier la méthode (...) d'Artistote, non pas tant celle qui est expressément thématisée dans l'Organon ou dans les excursus méthodologiques, mais celle qui se trouve concrètement mise en œuvre au vif des différents traités, et en particulier de la Physique. Déployant ce que l'auteur appelle lui-même une " sorte d'analyse structurale ", à travers une référence discrète mais significative, à Claude Lévi-Strauss et à Michel Foucault, l'ouvrage parvient à mettre en lumière un niveau originaire de la pensée aristotélicienne, lié aux schèmes du langage, de la fabrication, et surtout à l'expérience de la vie et du mouvement. Rien d'étonnant alors qu'une telle interprétation, attentive aux ambiguités ou aux apories de la recherche aristotélicienne, soit une des premières à avoir proposé une réinterprétation positive de la dialectique et des topiques.

Christopher Shields presents a new translation and commentary of Aristotle's De Anima, a work of interest to philosophers at all levels, as well as psychologists and students interested in the nature of life and living systems. The volume provides a full translation of the complete work, together with a comprehensive commentary. While sensitive to philological and textual matters, the commentary addresses itself to the philosophical reader who wishes to understand and assess Aristotle's accounts of the soul and body; perception; thinking; (...) action; and the character of living systems. It aims to present controversial aspects of the text in a neutral, fair-minded manner, so that readers can come to be equipped to form their own judgments. (shrink)

Ever since Aristotle's famous argument about the sea-battle tomorrow, there has been intensive and controversial discussion among philosophers whether the truth of statements about the future leads to determinism. Ther e is controversy about Aristotle's own solution to the problem, as well as the views of classical and medieval commentators on Aristotle. Seel's book attempts to answer this question for the Neoplatonist Ammonius (5th-6th century AD). In so doing, he also opens up new insights into Neoplatonic thought.

Paul Horwich gives the definitive exposition of a prominent philosophical theory about truth, `minimalism'. His theory has attracted much attention since the first edition of Truth in 1990; he has now developed, refined, and updated his treatment of the subject, while preserving the distinctive format of the book. This revised edition appears simultaneously with a new companion volume, Meaning; the two books demystify central philosophical issues, and will be essential reading for all who work on the philosophy of language.

Aristotle famously proclaims at Metaphysics Г.7, 1011b26–27: To men gar legein to on mê einai ê to mê on einai pseudos, to de to on einai kai to mê on mê einai alêthes, . . . Aristotle is inclined to think of this as a definition of truth and falsehood;1 we are inclined to wonder what he means by it. Perhaps a reasonable approximation in English would amount to something like: Tdf: For to state [of] that which is [that] it (...) is not or [of] that which is not [that] it is [is] false, and [to state of] that which is [that] it is and [of] that which is not [that] it is not [is] true. Many have considered this to be the expression of a correspondence theory of truth, and so it is tempting to .. (shrink)

This essay is a study of ontological commitment, focused on the special case of arithmetical discourse. It tries to get clear about what would be involved in a defense of the claim that arithmetical assertions are ontologically innocent and about why ontological innocence matters. The essay proceeds by questioning traditional assumptions about the connection between the objects that are used to specify the truth-conditions of a sentence, on the one hand, and the objects whose existence is required in order for (...) the truth-conditions thereby specified to be satisfied, on the other. This allows one to set forth an assignment of truth-conditions to arithmetical sentences whereby nothing is required of the world in order for the truth-conditions of a truth of pure arithmetic to be satisfied. The essay then argues that such an assignment can be used to account for the a priori knowability of certain arithmetical truths. (shrink)

The paper discusses the active part in the process of perceiving, usually expressed by the Greek word krinein. It is argued that krinein in one of its uses means "to judge" in the sense of judging a case, i. e. deciding it. It is not used for making statements. A second meaning of the Greek word is that of discerning or discriminating, and it is this meaning that plays a central part in Aristotle's theory of perception.

ARISTOTLE often claims that words are "homonymous" or "multivocal". He claims this about some of the crucial words and concepts of his own philosophy—"cause," "being," "one," "good," "justice," "friendship." Often he claims it with a polemical aim; other philosophers have wrongly overlooked homonymy and supposed that the same word is always said in the same way. Plato made this mistake; his accounts of being, good, and friendship are rejected because they neglect homonymy and multivocity. In Aristotle’s view Plato shared the (...) Socratic assumption about words and definitions. Socrates thought that when he asked "What is F?" some single definition of F could always be found to match the name "F." Aristotle thinks the Socratic question is important, but argues that it must be controlled by awareness of homonymy and multivocity. (shrink)

ARISTOTLE'S DESCRIPTION OF GOD'S ACTIVITY as νόησις νοήσεως, a "thinking of thinking," in chapters 7 and 9 of Metaphysics 12 raises some of the most significant and challenging questions in philosophy. These and other related chapters surely deserve Whitehead's praise in his own chapter on God in Science and the Modern World, where he accords to Aristotle "the position of the greatest metaphysician," adding, concerning Aristotle's God, "in his consideration of this metaphysical question [Aristotle] was entirely dispassionate; and he is (...) the last European metaphysician of first-rate importance for whom this claim can be made.... It may be doubted whether any properly general metaphysics can ever, without the illicit introduction of other considerations, get much farther than Aristotle.". (shrink)

Stephen Cole Kleene was one of the greatest logicians of the twentieth century and this book is the influential textbook he wrote to teach the subject to the next generation. It was first published in 1952, some twenty years after the publication of Godel's paper on the incompleteness of arithmetic, which marked, if not the beginning of modern logic. The 1930s was a time of creativity and ferment in the subject, when the notion of computable moved from the realm of (...) philosophical speculation to the realm of science. This was accomplished by the work of Kurt Gode1, Alan Turing, and Alonzo Church, who gave three apparently different precise definitions of computable. When they all turned out to be equivalent, there was a collective realization that this was indeed the right notion. Kleene played a key role in this process. One could say that he was there at the beginning of modern logic. He showed the equivalence of lambda calculus with Turing machines and with Godel's recursion equations, and developed the modern machinery of partial recursive functions. This textbook played an invaluable part in educating the logicians of the present. It played an important role in their own logical education.". (shrink)

What is truth. Paul Horwich advocates the controversial theory of minimalism, that is that the nature of truth is entirely captured in the trivial fact that each proposition specifies its own condition for being true, and that truth is therefore an entirely mundane and unpuzzling concept. The first edition of Truth, published in 1980, established itself as the best account of minimalism and as an excellent introduction to the debate for students. For this new edition, Horwich has refined and developed (...) his treatment of the subject in the light of subsequent discussions, while preserving the distinctive format that made the earlier edition so successful.

David Charles presents a major new study of Aristotle's views on meaning, essence, necessity, and related topics. These interconnected views are central to Aristotle's metaphysics, philosophy of language, and philosophy of science, and are also highly relevant to current philosophical debates. Charles aims to reach a clear understanding of Aristotle's claims and arguments, to assess their truth, and to evaluate their importance to ancient and modern philosophy.

Original and penetrating, this book investigates of the notion of inference from signs, which played a central role in ancient philosophical and scientific method. It examines an important chapter in ancient epistemology: the debates about the nature of evidence and of the inferences based on it--or signs and sign-inferences as they were called in antiquity. As the first comprehensive treatment of this topic, it fills an important gap in the histories of science and philosophy.

They reject the correspondence theory, insist truth is anemic, and advance an "anti-theory" of truth that is essentially a collection of platitudes: "Snow is white" is true if and only if snow is white; "Grass is green" is true if and only if grass is green. According to disquotationalists, the only profound insight about truth is that it lacks profundity. David contrasts the correspondence theory with disquotationalism and then develops the latter position in rich detail - more than has been (...) available in previous literature - to show its faults.

Exploring Aristotle's philosophical method and the merits of his conclusions, Irwin here shows how Aristotle defends dialectic against the objection that it cannot justify a metaphysical realist's claims. He focuses particularly on Aristotle's metaphysics, epistemology, philosophy of mind, and ethics, stressing the connections between doctrines that are often discussed separately.

The author investigates greek ontologies that apparently rely on a conflation of "binary" (x is f) and "monadic" (x is) uses of 'is'. He uses Aristotelian and other texts to support his proposal that these ontologies are explained by the Greeks using two alternative semantic analyses for 'x is F'. The first views it as asserting a relation between x and F, the second as asserting that a "predicative complex" exists, where a predicative complex is a complex consisting of x (...) and F. The article concludes by indicating some uses for the novel concept of predicative complex in aristotelian interpretation. (shrink)
