The only certainty is that nothing is certain. (Fuller version: This series of instances entangles unforeseeing mortality, so that among these things but one thing is in the least certain-that nothing certain exists, and that nothing is more pitiable, or more presnmptuous, than man! In Latin: Quae singula inprovidam mortalitatem involvunt, solum ut inter ista vel certu(m) sit nihil esse certi nec quicquam miserius homine aut superbius. Some sources have "certu", others "certum".)

The principle feature of American liberalism is sanctimoniousness. By loudly denouncing all bad things -- war and hunger and date rape -- liberals testify to their own terrific goodness. More important, they promote themselves to membership in a self-selecting elite of those who care deeply about such things. It's a kind of natural aristocracy, and the wonderful thing about this aristocracy is that you don't have to be brave, smart, strong or even lucky to join it, you just have to be liberal.

I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.
G. H. Hardy
Nothing in life is certain except death, taxes and the second law of thermodynamics. All three are processes in which useful or accessible forms of some quantity, such as energy or money, are transformed into useless, inaccessible forms of the same quantity. That is not to say that these three processes don't have fringe benefits: taxes pay for roads and schools; the second law of thermodynamics drives cars, computers and metabolism; and death, at the very least, opens up tenured faculty positions.

But those rare souls whose spirit gets magically into the hearts of men, leave behind them something more real and warmly personal than bodily presence, an ineffable and eternal thing. It is everlasting life touching us as something more than a vague, recondite concept. The sound of a great name dies like an echo the splendor of fame fades into nothing but the grace of a fine spirit pervades the places through which it has passed, like the haunting loveliness of mignonette.
James Thurber
The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. You'd be surprised how far that gets you.
