We have our hands, we have our brains, we have the challenge all around us, and we have within (from whatever source) the will to strive. That is enough; there is no need to assert 'belief' in that which we do not, as yet, know.
Robert A. HeinleinItโs not enough to be able to lie with a straight face; anybody with enough gall to raise on a busted flush can do that. The first way to lie artistically is to tell the truth โ but not all of it. The second way involves telling the truth, too, but is harder: Tell the exact truth and maybe all of itโฆbut tell it so unconvincingly that your listener is sure you are lying.
