Abstract

The paper discusses Timaeus 27d5-29b1, i.e. part of the proem of Timaeus' lecture. This passage contains the exposition of three principles (27d5-28b2) and their application to certain questions intended to lay the foundations for the subsequent cosmology (28b2-29b1). I argue that one of the main results Timaeus wants to deduce from his principles, i.e. the claim that the cosmos has been constructed by a divine craftsman, is not warranted by his principles and rests on a rather conspicuous flaw in the argument. I further discuss the question whether this mistake should be attributed to Plato or whether Plato deliberately has Timaeus commit this mistake; I argue for the second alternative.
