1. Do ideas of individuals (as well as of classes of individuals),
exist? This means that if I, in company with some other man, were to
trace ourselves back to the intelligible world, we would there find
separate individual principles corresponding to each of us. (This might
imply either of two theories.) Either, if the individual named Socrates
be eternal, and if the soul of Socrates be Socrates himself, then the
soul of each individual is contained in the intelligible world. Or
if, on the contrary, the individual named Socrates be not eternal, if
the same soul can belong successively to several individuals, such as
Socrates or Pythagoras, then (as Alcinoous, e. g., and other Platonists
insist), each individual does not have his idea in the intelligible
world.
