“If theft is advantageous to everyone who succeeds at it, and adultery is a good strategy, at least for males, for increasing presence in the gene pool, why do we feel they are wrong? Shouldn't the only morality that evolution produces be the kind Bill Clinton had - being sorry you got caught?”

“There is no indisputable proof for the big bang," said Hollus. "And there is none for evolution. And yet you accept those. Why hold the question of whether there is a creator to a higher standard?”
