#Rational

"Those at too great a distance may, I am well are, mistake ignorance for perspective."

"Good fellowship and friendship are lasting, rational and manly pleasures."

"I do not pretend to be able to prove that there is no God. I equally cannot prove that Satan is a fiction. The Christian god may exist; so may the gods of Olympus, or of ancient Egypt, or of Babylon. But no one of these hypotheses is more probable than any other: they lie outside the region of even probable knowledge, and therefore there is no reason to consider any of them."

"The rules of friendship are tacit, unconscious; they are not rational. In business, though, you have to think rationally."

"Most men either compromise or drop their greatest talents and start running after, what they perceive to be, a more reasonable success, and somewhere in between they end up with a discontented settlement. Safety is indeed stability, but it is not progression."

"I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own -- a God, in short, who is but a reflection of human frailty. Neither can I believe that the individual survives the death of his body, although feeble souls harbor such thoughts through fear or ridiculous egotisms."

"Our enemies are quite good for relentlessly keeping us sharp and on our toes. This especially goes for sincere philosophers. They use their enemies to challenge their arguments so that they can know the weak points in their own reasoning and how to argue for and strengthen their position. There are just none like one's enemies to always look for his mistakes and do it harder than anyone else."
