“It is interesting to notice that the extreme pessimist and the extreme optimist agree on at least one point. They both feel that we must sit down and do nothing in the area of race relations. The extreme optimist says do nothing because integration is inevitable. The extreme pessimist says do nothing because integration is impossible. But there is a third attitude that can be taken, namely the realistic position. The realist in this area seeks to combine the truths of two opposites, while avoiding the extremes of both, and so the realist would agree with the optimist that we have come a long, long way in grappling with this problem, but he would balance that by agreeing with the pessimist that we have a long, long way to go before the problem is solved in the United States. And it is this realistic position that I would like to use as a basis for our thinking together as we think of progress and as we think of the future of integration.”

“The intelligent investor is a realist who sells to optimists and buys from pessimists.”

Context: Why could the typical investor expect any better success in trying to buy at low levels and sell at high levels than in trying to forecast what the market is going to do? Because if he does the former he acts only after the market has moved down into buying levels or up into selling levels. His role is not that of a prophet but of a businessman seizing clearly evident investment opportunities. He is not trying to be smarter than his fellow investors but simply trying to be less irrational than the mass of speculators who insist on buying after the market advances and selling after it goes down. If the market persists in behaving foolishly, all he seems to need is ordinary common sense in order to exploit its foolishness.

“[A] pessimist gets nothing but pleasant surprises, an optimist nothing but unpleasant.”

Variant: Both optimists and pessimists contribute to society. The optimist invents the aeroplane, the pessimist the parachute.
