This essay argues that aristotle's doctrine of nominal definition is his semantic theory for natural-Kind terms. It offers a new interpretation of that doctrine. On this interpretation nominal definitions are initial working theoretical accounts of natural kinds which serve as starting points for scientific inquiry. As such, Nominal definitions have existential import. They make an implicit reference to the most familiar actual instances of the kinds they define and they define the essences of those kinds by reference to those instances. (...) Nominal definitions are, Thus, Accounts of real essences as much as real definitions. They are initial incomplete accounts of such essences and it is as such that they explicate the meanings of (natural-Kind) terms. (shrink)

An examination of the emergence of the phenomenon of deductive argument in classical Greek mathematics.

By a thorough study of the Posterior Analytics and related Aristotelian texts, Richard McKirahan reconstructs Aristotle's theory of episteme--science. The Posterior Analytics contains the first extensive treatment of the nature and structure of science in the history of philosophy, and McKirahan's aim is to interpret it sympathetically, following the lead of the text, rather than imposing contemporary frameworks on it. In addition to treating the theory as a whole, the author uses textual and philological as well as philosophical material to (...) interpret many important but difficult individual passages. A number of issues left obscure by the Aristotelian material are settled by reference to Euclid's geometrical practice in the Elements. To justify this use of Euclid, McKirahan makes a comparative analysis of fundamental features of Euclidian geometry with the corresponding elements of Aristotle's theory. Emerging from that discussion is a more precise and more complex picture of the relation between Aristotle's theory and Greek mathematics--a picture of mutual, rather than one-way, dependence.

Commentaries on Aristotle's writings have been produced since the 2nd century AD. This edition contains Greek commentaries on his work from the 3rd to the 8th centuries AD by, among others, Alexander of Aphrodiensias, Themistios, Joh. Philoponus, Simplicius in Greek.

Aristotle's solution to the problem raised in Ch. 4 depends on his account of how we arrive at thoughts on the basis of experience. In his view, we standardly acquire a term for a kind on the basis of contact with members of a kind, without thereby knowing that the kind in question exists. Further, we can grasp such terms without knowing that the kind has a unifying basic feature that explains its necessary properties. Our understanding of the kind is (...) to be compared with that of a craftsman and not that of a proto‐scientist. Aristotle's view is distinguished from several twentieth‐century accounts of these issues. (shrink)
