Abstract:  In the Phaedo Socrates says that as a young man he thought it a great thing to know the causes of things; but finding existing accounts unsatisfying, he fell back on a method of his own, hypothesizing that Forms are causes. I argue that part of what this hypothesis says is that certain phenomena – the ones for which it postulates Forms as causes – are the result of processes whose object was to produce them. I then use this conclusion to explain how Socrates’ discussion of causality in the Phaedo might be supposed to contribute to his final argument for immortality.
