Quote

The first requisite for immortality is death.

I have a strong preference for being alive.

I was fascinated by mortality. Most people are, even if they don't admit it.

I would like immortality.

If something comes to life in others because of you, then you have made an approach to immortality.

I don't believe in personal immortality; the only way I expect to have some version of such a thing is through my books.

Immortality is to live your life doing good things, and leaving your mark behind.

The only thing wrong with immortality is that it tends to go on forever.

Immortality is a long shot, I admit. But somebody has to be first.

I do not believe in immortality of the individual, and I consider ethics to be an exclusively human concern with no superhuman authority behind it.
