Immanuel Kant (1724-1804)
Major works
• Critique of Pure Reason (human reason)
• Critique of Practical Reason (ethics)
• Critique of Judgment (aesthetics)
• Religion Within the Limits of Reason Alone
Importance
• Most important philosopher of the Enlightenment
• His approach to knowledge combined elements from both rationalism and empiricism; He said all of our knowledge of the outside world comes to us via our senses but the mind also contributes to our knowledge of reality. The mind processes the data
• We do not know reality as it is in itself
• Made a distinction between phenomena and noumena
• Rejected all metaphysical knowledge (Kant bifurcated knowledge and put God in the upper story)
• Rejected all metaphysical arguments for the existence of God, including the ontological, cosmological, and teleological arguments
• Made a distinction between analytic and synthetic propositions
• Applied the “categorical imperative”—“Act only on the maxim whereby you can at the same time will that it should become a universal law” (moral oughtness)
• The notions of God, freedom, and immortality were regulative principles; though indemonstrable they gave coherence to ethical thought and behavior
• Grounded theology in morality instead of morality in theology
• Christianity was a way of teaching ethics for the philosophically unsophisticated
• Jesus was an enlightened moral teacher
• Said Hume awakened him from his dogmatic slumbers
• Held that enlightenment is man’s emergence from immaturity, man may think for himself without relying on some authority such as the Bible, church, or state
