Evolution, of course, is not something that simply applies to life here on earth; it applies to the whole universe.

Of course, Einstein was a very great scientist indeed, and I have enormous respect for him, and great admiration for the discoveries he made. But he was very committed to a view of the objectivity of the physical world.

Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.

God didn't produce a ready-made world. The Creator has done something cleverer than this, making a world able to make itself.

After all, the universe required ten billion years of evolution before life was even possible; the evolution of the stars and the evolving of new chemical elements in the nuclear furnaces of the stars were indispensable prerequisites for the generation of life.

Hope is much more than a mood. It involves a commitment to action.... What we hope for should be what we are prepared to work for...as far as that power lies in us.

I'm a very passionate believer in the unity of knowledge. There is one world of reality - one world of our experience that we're seeking to describe.
