Quote of this day

"If one cannot prove that a thing is, he may try to prove that it is not. And if he succeeds in doing neither (as often occurs), he may still ask whether it is in his interest to accept one or the other of the alternatives hypothetically, from the theoretical or the practical point of view. …Hence the question no longer is as to whether perpetual peace is a real thing or not a real thing, or as to whether we may not be deceiving ourselves when we adopt the former alternative, but we must act on the supposition of its being real."
- Immanuel Kant (I think this quote, and my former entry on Belief vs. Proof tie well into Kant's Critique of Pure Reason - even though the above is from his The Science of Right, the full text of which can be found here. Kant has always rocked my world, even with his weird then-fashionable-hairdo.)
