A paradigm shift is the best a scientist can hope for. Whenever I smell an opportunity like that, I go after it. You have a new discovery that something's working in a different way than you thought. And this is particularly true in molecular and cell biology, which is structural biology and has the least potential for controversy and partisanship among the biological scientists. You're dealing with a concrete object that's either there or not there.

The big question that scientists haven't even begun to get an answer for is how many species of microorganisms are there? Now, this is not stamp collecting. What we need is experts totally devoting their research to everything they can find out about every species, in a community of scientists who appreciate that every fact counts...everything new you learn about any species in any group is worth publishing somewhere.

Yes, the natural sciences are telling us a great deal about human origins, the origins of our species the origins of our minds; we're on our way to explaining a large part of it. I'll accept an answer provided only by such means as obtaining and exploring, analyzing and arguing over the evidence - not because of a scribe's myopic view of the subject written 500 years before the birth of Christ!

Nature holds the key to our aesthetic, intellectual, cognitive and even spiritual satisfaction.

[W]hen the martyr's righteous forebrain is exploded by the executioner's bullet and his mind disintegrates, what then? Can we safely assume that all those millions of neural circuits will be reconstituted in an immaterial state, so the conscious mind carries on?

No one knows the diversity in the world, not even to the nearest order of magnitude. ... We don't know for sure how many species there are, where they can be found or how fast they're disappearing. It's like having astronomy without knowing where the stars are.

Once I feel I'm right, I have enjoyed provoking.
