Life is a walk in the fog. Most people don't know that. They're fooled by the sunlight into thinking they can see what's ahead. But it's the reason they are forever getting lost or falling into ditches or committing matrimony.

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.

It is not faith per se that creates the problem; it is conviction, the notion that one cannot be wrong, that opposing views are necessarily invalid and may even be intolerable.

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.

Solitude is only a good idea if you have the right people along to share it.

But, come to think of it, there was no need to wait. Time travelers don't have to wait for anybody.

There is nothing that overwhelms the senses quite like an unwelcome silence.
