The only way to understand Islam is to understand the neuroses and psychoses of Muhammad. In this series, we explore the impact of Muhammad’s abnormal childhood development on his later life and teachings. As we will see, Islamic theology flows directly from Muhammad’s childhood traumas, via the “psychology of the defective father.” In Part One, we explore the “projection theory of belief in God” proposed by Ludwig Feuerbach and Sigmund Freud, along with the “defective father hypothesis” of Paul Vitz.
