Eric Hoffer -

People who bite the hand that feeds them usually lick the boot that kicks them.

Glenn Reynolds -

Communism capitalizes on envy, which is why it’s largely sustained by intellectuals, in whose personalities envy tends to be a particularly powerful component.

Richard P. Feynman -

It doesn’t matter how beautiful your theory is ... If it doesn’t agree with experiment, it’s wrong.

Issac Newton -

As to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

Sun Tzu -

If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. Attack him where he is unprepared, appear where you are not expected.

Alexander Solzhenitsyn -

It’s a universal law — intolerance is the first sign of an inadequate education, an ill-educated person behaves with arrogant impatience, whereas truly profound education breeds humility.
