Type II atheism is the denial of spirituality, typically by asserting a variant or update of the eighteenth century argument that “man is a machine.” The problem with this type of atheism, as existential philosophers have sensed, is that it leads to the abyss. There is no meaning in a world of machines. I believe that human actions have meaning. They express purposes and values. We are a species born to assert our values, not to discharge psychic energy.
