Quote by Stephen Jay Gould (1941-2002)

• In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

• 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.

• We have become, by the power of a glorious evolutionary accident called intelligence, the steward of life's continutity on earth. We did not ask for this role, but we cannot abjure it. We may not be suited to to it, but here we are.

• Creationist critics often charge that evolution cannot be tested, and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense.

• I am, somehow, less interested in the weight and convolutions of Einsteins brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops.

• The most erroneous stories are those we think we know best - and therefore never scrutinize or question.
