This profound work by Richard Carrier explores how to construct a coherent and fulfilling worldview without relying on supernatural explanations or deities. Carrier, a prominent advocate for naturalism, argues that objective morality, meaning, and purpose can indeed be found within a purely naturalistic framework. He rigorously challenges traditional religious and philosophical assumptions, offering a robust defense of metaphysical naturalism. The book delves into epistemology, ethics, and the nature of reality, presenting a comprehensive case for a rational, secular approach to life. It is an essential read for anyone interested in atheism, humanism, and philosophical naturalism.
