Members of the New Academy presented their sceptical position as the culmination of a progressive development in the history of philosophy, which began when certain Presocratics started to reflect on the epistemic status of their theoretical claims concerning the natures of things. The Academics' dogmatic opponents accused them of misrepresenting the early philosophers in an illegitimate attempt to claim respectable precedents for their dangerous position. The ensuing debate over the extent to which some form of scepticism might properly be attributed (...) to the Presocratics is reflected in various passages in Cicero's Academica. In this essay, we try to get clearer about the precise nature of the Academics' historical claim and their view of the general lesson to be learned from reflection on the history of philosophy down to their own time. The Academics saw the Presocratics as providing some kind of support for the thesis that things are non-cognitive, or, more specifically, that neither the senses nor reason furnishes a criterion of truth. As this view is susceptible to both 'dialectical' and non-dialectical readings, we consider the prospects for each. We also examine the evidence for the varied functions both of the Academics' specific appeals to individual Presocratics and of their collections of the Presocratics' divergent opinions. What emerges is a better understanding of why the Academics were concerned with claiming the Presocratics as sceptical ancestors and of the precise manner in which they advanced this claim. (shrink)

Particularly during the past twenty five years, there has been an outstanding advance in the study of ancient skepticism, both in its Pyrrhonian and Academic varieties. This is reflected in the publication of a considerable number of works about the nature and consistency of those philosophical outlooks, as well as about their influence on the development of early modern philosophy and their relevance to present day epistemological discussions. Most of these works concern Pyrrhonian skepticism. This predominance of interest in Pyrrhonism (...) over Academic skepticism also manifests itself in the fact that, whereas in recent years several new translations of Sextus Empiricus' writings (our principal source for Pyrrhonism) have appeared in the most important European languages, the same has not happened with Cicero's Academica, which is our main source of information about the philosophy of the skeptical Academy. Even though Sextus'. (shrink)
