It may be that everything we do is determined by some grand unified theory. If that theory has determined that we shall die by hanging, then we shall not drown. But you would have to be awfully sure that you were destined for the gallows to put to sea in a small boat during a storm. I have noticed that even people who claim that everything is predestined and that we can do nothing to change it look before they cross the road. Maybe it’s just that those who don’t look don’t survive to tell the tale.

Reprinted in Black Holes and Baby Universes, and Other Essays, ch. 12 (1994). Hawking's thesis that the universe is actually deterministic, but too complex to be predictable, so acting as though free will exists is useful socially and, like fluid dynamics equations, satisfactory for most purposes.

It is a waste of time to be angry about my disability. One has to get on with life and I haven’t done badly. People won’t have time for you if you are always angry or complaining.

So Einstein was wrong when he said “God does not play dice”. Consideration of black holes suggests, not only that God does play dice, but that He sometimes confuses us by throwing them where they can’t be seen.

"Not only does God play dice, but... he sometimes throws them where they cannot be seen." "God not only plays dice, He sometimes throws the dice where they cannot be seen."
My expectations were reduced to zero when I was 21. Everything since then has been a bonus.

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? 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?

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.

A Brief History of Time (1988)
For millions of years, mankind lived just like the animals. Then something happened which unleashed the power of our imagination. We learned to talk and we learned to listen. Speech has allowed the communication of ideas, enabling human beings to work together to build the impossible. Mankind’s greatest achievements have come about by talking, and its greatest failures by not talking.

The victim should have the right to end his life, if he wants. But I think it would be a great mistake. However bad life may seem, there is always something you can do, and succeed at. While there’s life, there is hope.
