Andrea Falcon places the evidence in its context, the revival of interest in Aristo- tle’sphilosophythattookplaceinthefirstcenturybce.Xenarchusis oftenpresentedasarebel,challengingAristotleandtheAristotelian tradition. Falcon argues that there is more to Xenarchus and his philosophical activity than an opposition to Aristotle; he was a cre- ativephilosopher,andhisviewsarebestunderstoodasanattemptto revise and update Aristotle’s philosophy.

InmemoryofBobSharples, whosupportedthisproject Aristotle’sphysicsisoneofthemostastonishingsystemshumanrea- son has ever built; it gave answers to all the questions the ancients had about the heavens and their motions, the elements and their transformations, the most precise and complete answers offered up untilthen,andalltheseanswerswerelogicallyorganizedinatheory comparedtowhichallpriordoctrinesseemedtobemerebeginnings. That such a system exercised on minds the powerful seduction that mostoftheArabicorChristianphilosophersexperiencedintheMid- dle Ages, is easy to understand. In contrast, it is surprising to learn thattheimmediatesuccessorsofAristotleprovedthemselvestobe,in general,rebellioustothisinfluence.

And when I discovered that this reception was at best mixed,whatitmeanttobeaPeripateticphilosopherinantiquitybecame an interesting and urgent question. This study attempts to answer that question. I am throughout indebted to the work of Bob Sharples on the Peripatetic tradition, which has been a model of scholarship as well as an invaluablesourceofinformation.
