The universe in some sense must have known that we were coming.

It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment.

Science and religion are, of course, two different ways of looking at the universe; and it's the same universe with two different windows.

Every orchid or rose or lizard or snake is the work of a dedicated and skilled breeder. There are thousands of people, amateurs and professionals, who devote their lives to this business. Now imagine what will happen when the tools of genetic engineering become accessible to these people.

Science is my territory, but science fiction is the landscape of my dreams.

I think science and religion should be separate.

The science window gives you a view of the world, and the religion window gives you a totally different view. You can't look at both of them at the same time, but they're both true.
