Anybody who is interested in philosophy might find these quite interesting. I have found all three of Immanuel Kant's critiques from the internet (Critique of Judgement, Critique of Practical Reason, Critique of Pure Reason) and have uploaded it into one place. All three books are in the public domain (so I should be fine with all the copyright issues). If I am wrong about these books being in the public domain, please tell me and I will remove it.
