 However, McTaggart denied that the truth of optimism required the truth of theism. As noted earlier, McTaggart was throughout his adult life an unwavering atheist. In chapter VI of Some Dogmas of Religion, McTaggart defines “God” as “a being who is personal, supreme, and good.” Although McTaggart’s definition requires that God be a person in the philosophical sense, it neither requires that God be omnipotent nor requires that God be omnibenevolent. It merely requires that God be more powerful than any created thing and that God be more good than evil. McTaggart held that the three most popular arguments for the existence of God, which he took to be the cosmological argument, the argument from design, and the argument from goodness, cannot prove the existence of an omnipotent God. McTaggart also raises worries in this chapter about the coherence of the notion of omnipotence by calling attention to various paradoxes and puzzles surrounding the notion. It should be noted that McTaggart’s conception of omnipotence is very strong: for one to be omnipotent in his sense one must be able to perform impossible tasks.
