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.

This book carries forward the investigation I conducted in Aristotle and
theScienceofNature:UnitywithoutUniformity(Cambridge2005).While
workingonit,itbecamecleartomethatAristotle’sphysicsisbothexcep-
tionalandanomalousinthecontext ofancient physics; atthatpoint,the
decision to study the reception of this physics in the Peripatetic tradition
was easy to take. 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.

Description:A full study of the remaining evidence for Xenarchus of Seleucia, one of the earliest interpreters of Aristotle. Andrea Falcon places the evidence in its context, the revival of interest in Aristotle's philosophy that took place in the first century BCE. Xenarchus is often presented as a rebel, chal
