Never attribute to malice that which can be adequately explained by stupidity. Never underestimate the power of human stupidity.
Robert A. HeinleinTheology is never any help; it is searching in a dark cellar at midnight for a black cat that isn't there. Theologians can persuade themselves of anything.
Robert A. HeinleinBut 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. Unless one accepts that, anything one says about morals, war, politics, you name it, is nonsense. 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.
