Here's a good one from Thomas Paine:
'He who is the author of a war lets loose the whole contagion of hell and opens a vein that bleeds a nation to death.'
Right right. I see it quoted out of context so often, I felt obligated to defend the maligned Philosopher. He was very humanistic, in a way that was positive and strong, as opposed to "fluffy."
