One thing I love about Penrose is his humility. He didn't fall
  into the popularity/celebrity trap. I used to have one or two
  minor quibbles but they must be so minute because I don't even
  remember them. The man is amazing. He's a proper old-school
  humanist. While atheists like to claim him as their own, I don't
  recall him ever stating it and strikes me rather akin to Carl
  Sagan's agnosticism - ie - good old fashioned humanist, doing
  science for the science and leaving the rest as
  unknown-right-now. ""I think I would say that the universe has a
  purpose, it's not somehow just there by chance ... some people,
  I think, take the view that the universe is just there and it
  runs along * it's a bit like it just sort of computes, and we
  happen somehow by accident to find ourselves in this thing. But
  I don't think that's a very fruitful or helpful way of looking
  at the universe, I think that there is something much deeper
  about it.""
