Aristotle determines eristic argument as argument which either operates upon the basis of acceptable premisses and merely give the impression of being deductive, or argument which truly is deductive but operates upon the basis of premisses which seem to be acceptable, but are not. I attempt to understand what Aristotle has in mind when he says that someone is deceived into accepting premisses which seem to be acceptable but which are really not, and how this disqualifies such arguments from being (...) dialectical. In the first section of the paper I interpret Aristotle’s notion of ἔνδοξα in terms of a relational concept of acceptability. Real ἔνδοα are propositions which are accepted by a qualified group or individual. False ἔνδοα may also be accepted by someone or some group, and may even be true, but they are used to serve the purposes of eristical argumentation, which departs from certain standards of dialectical argumentation articulated in the notion of ἔνδοξα as a norm for premiss-acceptance. In particular, eristic arguments may even be valid in the sense of a συλλογισμός while still failing to be proper dialectical arguments. In the second part of the paper I consider how this can be, in examining certain types of fallacies in the Sophistical Refutations and the relationship between fallacious argumentation and false ἔνδοξα.

The discussion of the Principle of Non-Contradiction (PNC) in Aristotle’s Metaphysics Γ is usually taken to include three ‘versions’ of the principle: an ontological, psychological, and logical one. In this article I develop an interpretation of Metaphysics Γ3 and a parallel text, De interpretatione 14, in order to show that these texts are concerned with two related but different principles: a version of the Principle of Identity, and a corollary to this, which concerns the ability to accept two ‘opposite’ items (...) at the same time. I argue that these principles must be considered separately in order to properly understand Aristotle’s remarks about PNC in Metaphysics Γ, and in order to defend his approach in these remarks against certain objections raised against the discussion in Metaphysics Γ by Jan Łukasiewicz in his "Über den Satz des Widerspruchs bei Aristoteles". The main result of my interpretation is to distinguish in the discussion of PNC in Metaphysics Γ three principles: one concerning linguistic items (words and statements), one concerning thoughts (δόξαι), and one concerning objects or states of affairs.

Aristotle determines eristic argument as argument which either operates upon the basis of acceptable premisses (endoxa) and merely give the impression of being deductive, or argument which truly is deductive but operates upon the basis of premisses which seem to be acceptable, but are not (or, again, argument which uses both of these mechanisms). I attempt to understand what Aristotle has in mind when he says that someone is deceived into accepting premisses which seem to be acceptable but which are (...) really not, and how this disqualifies such arguments from being dialectical. In the first section of the paper I interpret Aristotle’s notion of endoxa in terms of a relational concept of acceptability. Real Índoxa are propositions which are accepted by a qualified group or individual. False endoxa may also be accepted by someone or some group, and may even be true, but they are used to serve the purposes of eristical argumentation, which departs from certain standards of dialectical argumentation articulated in the notion of endoxa as a norm for premiss-acceptance. In particular, eristic arguments may even be valid in the sense of a syllogismos while still failing to be proper dialectical arguments. In the second part of the paper I consider how this can be, in examining certain types of fallacies in the Sophistical Refutations and the relationship between fallacious argumentation and false endoxa.

In this paper I provide support for the view that at least some forms of adversariality in argumentation are legitimate. The support comes from Aristotle’s theory of illegitimate adversarial argumentation in dialectical contexts: his theory of eristic in his work On Sophistical Refutations. Here Aristotle develops non-epistemic standards for evaluating the legitimacy of dialectical procedures, standards which I propose can be understood in terms of the pragmatic notion of context as common ground. Put briefly, Aristotle makes the answerer’s meaning in (...) giving assent in dialectical contexts the basis for further moves in the game of dialectic. Moves which subvert the answerer’s meaning or do not solicit the answerer’s consent are marked as eristic, i.e. adversarial in a problematic sense. I conclude with remarks on what Aristotle’s theory may teach us about how semantic features relate to the normative evaluation of argumentation. (shrink)

In this response I consider the implications of Jan Szaif’s suggestion that there is a tight “conceptual affinity” between Books I and X of the Nicomachean Ethics. I argue against one view which could claim such a thesis as an ally: the view which maintains that the Nicomachean Ethics is based upon the kind of conceptual cohesion supplied by a supposed metaphysical foundation for claims about happiness.

Once upon a time in the twentieth century, it was considered good sense by some to think that Aristotle began his De anima with a series of very Aristotelian theories about the soul, and that the function of its first book was to eristically taunt his predecessors for failing to appreciate hylomorphism, or patronizingly praise them for getting the odd bit right. Jason Carter deserves our thanks for showing how wrong-headed this reading of Aristotle is. His book begins with the (...) much more sensible assumption that the review of previous δόξαι in DA I plays an important and even constitutive role for theses at the core of Aristotle's theory of soul and living things, prominent among them these two: that the soul...
