Introduction

A treatise in three books on what distinguishes living from non-living things. Aristotle surveys earlier theories and then defines the soul as the “first actuality” of a natural body that has life potentially: not a separate thing in the body but its organisation and capacity to live. Plants have nutritive soul, animals also perception and desire, humans also thought. Much of the work deals with the five senses and with imagination. A short, obscure chapter (III.5) on an intellect that “makes” all things set off centuries of debate among Greek, Arabic and Latin commentators about whether this intellect is individual or shared by all.
