Lies hold civilization together. If people ever seriously begin telling each other what they really think, there'd be no peace. Good-bye to tact. Good-bye to being polite. Good-bye to showing tolerance for other people's buffooneries. The fact that we claim to admire Truth is probably the biggest lie of all. But that's part of the charade, part of what makes us human, and we do not even think about it. In effect, we lie to ourselves. Lies are only despicable when they betray a trust.

All of the important things ... will turn out to be universally shared. It's why there will be no true aliens.

Idiots are not responsible for what they do. The real guilt falls on rational people who sit on their hands while morons run wild. You can opt out if you want to. Play it safe. But if you do, don't complain when the roof comes down.

Throughout our long and sorry history it has been men who supposed themselves to be exemplars of integrity who have done all the damage. Every crusade, whether for decent literary standards or to cover women's bodies or to free the holy land, had been launched, endorsed, and enthusiastically perpetrated by men of character.

See what the world looks like from orbit. Well, in that way, at least, there was profit to be had. Nobody could look down at the planet, green and blue, with no borders in evidence and no sign of human habitation, and not get his perspective forever altered.

Faith is conviction without evidence, and sometimes even in the face of contrary evidence. In some quarters, this quality is perceived as a virtue.

The problem is that too often the only people who can act don't want change. Power doesn't so much corrupt as it breeds conservatism.
