Immanuel Kant

Immanuel Kant was a German philosopher and one of tbe Enlightenment's main thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aestbetics have made him one of tbe most influential figures in modern philosophy. In his doctrine of transcendental idealism, Kant argued that space and time are mere "forms of intuition" which structure all experience, and tberefore, while "things-in-tbemselves" exist and contribute to experience, tbey are nonetbeless distinct from tbe objects of experience. From this it follows that tbe objects of experience are mere "appearances" and that tbe nature of things as tbey are in tbemselves is unknowable to us. In an attempt to counter tbe skepticism he found in tbe writings of philosopher David Hume, he wrote tbe Critique of Pure Reason, one of his most well-known works.
