The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

To confine our attention to terrestrial matters would be to limit the human spirit.

There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

Someone told me that each equation I included in the book would halve the sales.

Not only does God play dice, but... he sometimes throws them where they cannot be seen.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?
