This book deals with things and how they relate to theirs users, a set of similar units called the Others. Their relations bring them to the attention of another set of similar units, customarily called Individuals or Selves, here redefined and renamed Connectuals, Dividuals or Plecads. The familiar theory of praxis - doings, work, business - is not quite all there is to being wise to the Others, or Other-Wise, which is rather a theory of Chresis, to use, treat, consult, encounter. With bibliography and index.
