History is the most dangerous product which the chemistry of the mind has concocted. Its properties are well known. It produces dreams and drunkenness. It fills people with false memories, exaggerates their reactions, exacerbates old grievances, torments them in their repose, and encourages either a delirium of grandeur or a delusion of persecution. It makes whole nations bitter, arrogant, insufferable and vainglorious.

The best way to make your dreams come true is to wake up.

The mind has transformed the world, and the world is repaying it with interest. It has led man where he had no idea how to go.

History is the most dangerous product evolved from the chemistry of the intellect. ...History will justify anything. It teaches precisely nothing, for it contains everything and furnishes examples of everything.

In the physical world, one cannot increase the size or quantity of anything without changing its quality. Similar figures exist only in pure geometry.
