In this lecture series from a major 20th-century intellectual, the state of Western culture's moral and emotional emptiness is traced to the decline of formal religion. Alternate mythologies offered by Marxism, Freudian psychoanalysis, Levi-Straussian anthropology, and the occult are examined to consider the spiritual and intellectual ideologies that have attempted to fill the void left by formal religion's deterioration. In the argument presented, the pursuit of religious truth offers the opportunity for renewal of hope in an increasingly complex world.
