Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation forthe existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.
Richard DawkinsIf you have a faith, it is statistically overwhelmingly likely that it is the same faith as your parents and grandparents had. No doubt soaring cathedrals, stirring music, moving stories and parables, help a bit. But by far the most important variable determining your religion is the accident of birth. The convictions that you so passionately believe would have been a completely different, and largely contradictory, set of convictions, if only you had happened to be born in a different place.
Richard DawkinsIt is quite true that many scientists, many physicists, maintain that the physical constants, the half dozen or so numbers that physicists have to simply assume in order to derive the rest of their understanding ... have to be assumed. You can't provide a rationale for why those numbers are there. Physicists have calculated that if any of these numbers was a little bit different, the universe as we know it wouldn't exist.
