Abstract
After reviewing the highly valuable contents of the book, I sketch two arguments in favor of the view that the passage of time is not, as the author claims, a mere byproduct of our experience. The first criticism involves the meaning of causation. The second Prosser's explanation of why it seems to us that time really passes, appealing to the distinction between endurantism and perdurantism. By suggesting the possibility that this distinction is not metaphysically genuine, I question the soundness of his explanation
