“Materialism is a conviction based not upon evidence or logic but upon what Carl Sagan (speaking of another kind of faith) called a “deep-seated need to believe.” Considered purely as a rational philosophy, it has little to recommend it; but as an emotional sedative, what Czeslaw Milosz liked to call the opiate of unbelief, it offers a refuge from so many elaborate perplexities, so many arduous spiritual exertions, so many trying intellectual and moral problems, so many exhausting expressions of hope or fear, charity or remorse. In this sense, it should be classified as one of those religions of consolation whose purpose is not to engage the mind or will with the mysteries of being but merely to provide a palliative for existential grievances and private disappointments. Popular atheism is not a philosophy but a therapy.”
