Contrary to current cynicism about past golden ages, the abstraction known as 'the intelligent layperson' does exist - in the form of millions of folks with a passionate commitment to continuous learning.

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

Natural selection may lead to benefits for species, but these `higher' advantages can only arise as sequelae, or side consequences, of natural selection's causal mechanism: differential reproductive success of individuals.

The fundamentalists, by 'knowing' the answers before they start, and then forcing nature into the straitjacket of their discredited preconceptions, lie outside the domain of science - or any honest intellectual inquiry.

Change is more often a rapid transition between two stable states than a continuous transformation at slow and steady rates. . . .Change occurs in large leaps following a slow accumulation of stress that a system resists until it reaches the breaking point. Heat water, and it eventually boils. Oppress the workers more and more and bring on the revolution.

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists-whether through design or stupidity, I do not know-as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.

The causes of life's history [cannot] resolve the riddle of life's meaning.
