Ever since antiquity, scholars of Plato have been evenly divided between those who identify Plato’s supreme god with a form (usually, the form of the good) and those who identify Plato’s supreme god with a soul (usually, the soul of the cosmos). But Plato never aims to give us a science of god; he aims to show us how to become like god. I distinguish three Platonic ascents to the divine: a metaphysical ascent to the form of the good; a cosmological ascent to the cosmic soul; and a religious ascent to the proper civic cult. These three ascents form a nested hierarchy, such that the cosmological ascent presupposes the metaphysical ascent, while the religious ascent presupposes the cosmological ascent. The metaphysical and cosmological ascents culminate in the religious ascent because becoming like god for Plato is a civic project. A philosopher can save herself only by saving her city.
