Immanuel Kant is considered a major philosopher of the Enlightenment because his work represents the culmination of the era's philosophical development, effectively synthesizing the competing traditions of rationalism and empiricism.123

His significance stems from several key contributions:

  • Critical Examination of Reason: Kant redefined the task of philosophy as the critical investigation of the powers and limits of human reason. He sought to determine what reason could achieve independently of experience and where it must acknowledge its boundaries.13
  • The Copernican Revolution: He introduced a "Copernican" shift in philosophy, proposing that objects must conform to the structures of human knowledge, rather than human knowledge conforming to objects.14
  • Systematic Critiques: Kant developed a unique philosophical form—the "critique"—to systematically examine reason in its three primary domains: thinking (science), willing (ethics), and feeling (aesthetics).15
  • Defense of Autonomy: In his moral philosophy, he emphasized the autonomy of the will, arguing that individuals act freely when they follow universal moral laws, such as the categorical imperative.4
