We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity.

Every major religion today is a winner in the Darwinian struggle waged among cultures, and none ever flourished by tolerating its rivals.

We are compelled to drive toward total knowledge, right down to the levels of the neuron and the gene. When we have progressed enough to explain ourselves in these mechanistic terms...the result might be hard to accept.

The solutions like freezing zygotes, fertilized eggs, of all kinds of animals and so on, or keeping them in zoos and having arboreta where we have trees, all these things have been promoted. Even getting the complete genetic code of various fishes so we can let them pass away and then we'll pull them back. That is science fiction run amok.

By any reasonable measure of achievement, the faith of the Enlightenment thinkers in science was justified.

The evolutionary epic is ... the best myth we will ever have.

I believe that traditional religious belief and scientific knowledge depict the universe in radically different ways. At the bedrock they are incompatible and mutually exclusive.
