The 3-legged stool of understanding is held up by history, languages, and mathematics. Equipped with those three you can learn anything you want to learn. But if you lack any one of them you are just another ignorant peasant with dung on your boots.
Robert A. HeinleinAnyone who clings to the historically untrue-and thoroughly immoral-doctrine that, 'violence never settles anything' I would advise to conjure the ghosts of Napoleon Bonaparte and the Duke of Wellington and let them debate it. The ghost of Hitler could referee, and the jury might well be the Dodo, the Great Auk and the Passenger Pigeon. Violence, naked force, has settled more issues in history than has any other factor, and the contrary opinion is wishful thinking at its worst. Breeds that forget this basic truth have always paid for it with their lives and freedom.
Robert A. HeinleinIt was better to live with disappointment and frustration than to live without hope.
