But does Man have any 'right' to spread through the universe? Man is what he is, a wild animal with the will to survive, and (so far) the ability, against all competition.

Correct morals arise from knowing what man is, not what do-gooders and well-meaning old Aunt Nellies would like him to be. The Universe will let us know - later - whether or not Man has any "right" to expand through it.

Robert A. HeinleinI've found out why people laugh. They laugh because it hurts- because it's the only thing that'll make it stop hurting...
