“[The] theme is, in brief, that the Demiurge introduced standards into the created world to serve as criteria of judgment. These standards are perfectly realized in this world; and their function is primarily epistemological. The Demiurge is not primarily a source of order or beauty, but rather his aim is to “improve the world’s intelligibility” (55), that is to “improve our cognitive capacities” (61), by providing immanent standards. ... Throughout the book, the arguments are presented clearly and carefully, with appropriate references to previous discussions. ... This book provides a useful and interesting perspective on cosmological problems discussed in recent decades.”
