Prisons are needed only to provide the illusion that courts and police are effective. They’re a kind of job insurance. - Frank Herbert

He who can destroy a thing has the real control of it.

It's rooted in the fears to which all men are heir and, thus, deserves sympathy, not censure or laughter. The dream may be out of touch with history, but it's a good dream, and it doesn't appear to have been used to bilk gullible widows out of their savings. Never mind that we have a consistent record of slaughtering our messiahs. Look beyond the wacky arguments to the motivation — that sense of brotherhood which is all that has ever saved mankind from going over the brink.

If you ask "Should we be in space?" you ask a nonsense question. We are in space. We will be in space.
