Super Short Summary

36 Arguments for the Existence of God by Rebecca Goldstein follows atheist psychology professor Cass Seltzer, whose book, The Varieties of Religious Illusion, debunks the belief in God through thirty-six arguments, challenging religious beliefs and traditions. As Cass gains fame and begins an affair with mathematician Lucinda Mandelbaum, he reflects on his past influences and his mentor, Jonas Elijah Klapper. Cass is particularly intrigued by Azarya Valdener, a prodigious mathematician from an Orthodox Jewish sect, who believes in the coexistence of science and religion, prompting Cass to reconsider the complexity of the arguments for and against God's existence.
