It is a paradox of Life that all species breed past mere replacement. Any paradise of plenty soon fills to become paradise no more.
David BrinFor all its beauty, honesty, and effectiveness at improving the human condition, science demands a terrible price - that we accept what experiments tell us about the universe, whether we like it or not. It's about consensus and teamwork and respectful critical argument, working with, and through, natural law. It requires that we utter, frequently, those hateful words - 'I might be wrong.'
David Brin
