A Monumental Figure of Western Thought Wrestles with the Question of God: Immanuel Kant (1724-1804) is one of the most influential philosophers in the history of Western philosophy. His contributions have had a profound impact on almost every philosophical movement that followed him. His teachings on religion were unorthodox in that they were based on rationality rather than revelation. Tho logically proving God's existence might be impossible, it's morally reasonable to and "act as if there be a God. and " His strictly rational approach was considered so scandalous that the King of Prussia forbid him to teach or write further on religious subjects, which Kant obeyed until the king's death. A work of major importance in the history of Western religious thought, Religion Within the Limits of Reason Alone represents a great philosopher's attempt to spell out the form and u0026 content of a type of religion grounded in moral reason and u0026 meeting the needs of an ethical life.
