It is an essential part of the scientific enterprise to admit ignorance, even to exult in ignorance as a challenge to future conquests.
Richard DawkinsOne of the possible reasons why we might be good is that we're frightened, frightened of God. We want the reward in Heaven, we don't want to go to Hell. That would be an ignoble, ignominious reason for being good, and I think that if anybody was good to you just because they hoped for a heavenly reward, you wouldn't respect them, you'd probably give them a wide berth.
Richard DawkinsFive per cent vision is better than no vision at all. Five per cent hearing is better than no hearing at all. Five per cent flight efficiency is better than no flight at all. It is thoroughly believable that every organ or apparatus that we actually see is the product of a smooth trajectory through animal space, a trajectory in which every intermediate stage assisted survival and reproduction.
