Hackforth and Menn make a strong case for the identity of nous and the demiurge in Plato, but I argue that it does not hold in the case of the Philebus, where the demiurge is kept in the background, and the world-soul is in fact the referent in the passage assigning nous to the class of cause as governor of the universe. In the Statesman, the world-soul had had to own the problem of natural catastrophe, and I suggest that in (...) the Philebus the role and functions of the world-soul are enhanced in an attempt to make it the basis for a solution to that problem.
