History reports that the men who can manage men manage the men who can manage only things, and the men who can manage money manage all.

In the end, nothing is lost. Every event, for good or evil, has effects forever.

Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement.

Science without philosophy, facts without perspective and valuation, cannot save us from havoc and despair. Science gives us knowledge, but only philosophy can give us wisdom.

In progressive societies the concentration[of wealth] may reach a point where the strength of number in the many poor rivals the strength of ability in the few rich; then the unstable equilibrium generates a critical situation, which history has diversely met by legislation redistributing wealth or by revolution distributing poverty.

If our economy of freedom fails to distribute wealth as ably as it has created it, the road to dictatorship will be open to any man who can persuasively promise security to all.

Truth will not make us rich, but it will make us free.
