Robert Heinlein - Time Enough for Love, 1978

A poet who reads his verse in public may have other nasty habits.
Robert Heinlein
Anyone who clings to the historically untrue - and thoroughly immoral - doctrine that violence never settles anything I would advise to conjure up the ghosts of Napoleon Bonaparte and the duke of Wellington and let them debate it. The ghost of Hitler would referee. Violence, naked force, has settled more issues in history than any other factor, and the contrary opinion is wishful thinking at its worst. Breeds that forgot this basic truth have always paid for it with their lives and there freedoms.
Robert Heinlein - Excerpt from the notebooks of Lazarus Long, "Time Enough for Love"
People who go broke in a big way never miss any meals. It is the poor jerk who is shy a half slug who must tighten his belt.

That old saw about the early bird just proves that the worm should have stayed in bed.
Robert Heinlein
In the absence of clearly-defined goals, we become strangely loyal to performing daily trivia until ultimately we become enslaved by it.
Robert Heinlein - Stranger in a Srange Land
Love is the condition in which the happiness of another person is essential to your own.... Jealousy is a disease, love is a healthy condition. The immature mind often mistakes one for the other, or assumes that the greater the love the greater the jealousy.
Robert Heinlein
Writing is not necessarily something to be ashamed of, but do it in private and wash your hands afterwards.
Robert Heinlein - The Notebooks of Lazurus Long
A generation which ignores history has no past and no future.

The supreme irony of life is that hardly anyone gets out of it alive.

Specialization is for insects.

To be matter of fact about the world is to blunder into fantasy -- and dull fantasy at that, as the real world is strange and wonderful.
Robert Heinlein - Time Enough for Love (1972)
History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help. But, like dandruff, most people do have a religion and spend time and money on it and seem to derive considerable pleasure from fiddling with it.
