The dogmatist within is always worse than the enemy without.

History employs evolution to structure biological events in time.

Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air, pending the outcome. And humans evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered.

So much of science proceeds by telling stories.

Science is all those things which are confirmed to such a degree that it would be unreasonable to withhold one's provisional consent.

The most important scientific revolutions all include, as their only common feature, the dethronement of human arrogance from one pedestal after another of previous convictions about our centrality in the cosmos.

Life shows no trend to complexity in the usual sense-only an asymmetrical expansion of diversity around a starting point constrained to be simple.
