Immanuel Kant’s Critique of Pure Reason is a monumental work in philosophy that has profoundly impacted the study of metaphysics and epistemology. But it’s not the only critique that Kant produced. In fact, the Critique of Practical Reason, his second critique, is equally significant, as it focuses on his moral philosophy and views on free will. It’s regarded as a masterpiece of philosophical writing, in which Kant critically examines the use of reason in the moral domain. The theoretical use of reason was his primary concern, as it dealt with objects of the cognitive faculty alone. Kant approached this use of reason properly by applying a critical examination to the pure faculty of cognition. His insights have revealed that this examination could easily surpass what we think we know, raising suspicions about our basic assumptions.
