Humans have more moral responsibility perhaps, because they are capable of reasoning.

Charles Darwin made arguably the greatest discovery any human has ever made. He was a man of great persistence. He wasn't probably a natural genius, he worked very hard - even though he was an invalid. He was a great family man, a very nice man. I think he was admirable in all sorts of ways.

What are all of us but self-reproducing robots? We have been put together by our genes and what we do is roam the world looking for a way to sustain ourselves and ultimately produce another robot child.

I've always been antagonistic to any naïve application of the selfish gene theory to politics. Some people have attempted to suggest that it means we are selfish or we should be selfish.

Most people, I believe, think that you need a God to explain the existence of the world, and especially the existence of life. They are wrong, but our education system is such that many people don't know it.

I find many of answers in the spiritual realm. That in no way compromises my ability to think rigorously as a scientist.

Maybe somewhere in some other galaxy there is a super-intelligence so colossal that from our point of view it would be a god. But it cannot have been the sort of God that we need to explain the origin of the universe, because it cannot have been there that early.
