In their recently aborted struggle to inject Genesis literalism into science classrooms, fundamentalist groups followed their usual opportunistic strategy of arguing two contradictory sides of a question when a supposed rhetorical advantage could be extracted from each.

Science is not a heartless pursuit of objective information; it is a creative human activity.

Nature is what she is - amoral and persistent.

Anything, even the conceptually most complex material, can be written for general audiences without any dumbing down. Of course you have to explain things carefully. This goes back to Galileo, who wrote his great books as dialogues in Italian, not as treatises in Latin. And to Darwin, who wrote The Origin of Species for general readers. I think a lot of people pick up Darwin's book and assume it must be a popular version of some technical monograph, but there is no technical monograph. That's what he wrote. So what I'm doing is part of a great humanistic tradition.

Results rarely specify their causes unambiguously. If we have no direct evidence of fossils or human chronicles, if we are forced to infer a process only from its modern results, then we are usually stymied or reduced to speculation about probabilities. For many roads lead to almost any Rome.

Few tragedies can be more extensive than the stunting of life, few injustices deeper than the denial of an opportunity to strive or even to hope, by a limit imposed from without, but falsely identified as lying within.

I strongly reject any conceptual scheme that places our options on a line, and holds that the only alternative to a pair of extreme positions lies somewhere between them. More fruitful perspectives often require that we step off the line to a site outside the dichotomy.
