More quotes by Stephen Jay Gould

Image
Recapitulation provided a convenient focus for the persuasive racism of white scientists they looked to the activities of their own children for comparison with normal adult behavior in lower races.
Stephen Jay Gould
Image
Life began three and a half billion years ago, necessarily about as simple as it could be, because life arose spontaneously from the organic compounds in the primeval oceans.
Stephen Jay Gould
Image
The modern theory of evolution does not require gradual change. It in fact, the operation of Darwinian processes should yield exactly what we see in the fossil record. It is gradualism that we must reject, not Darwinism.
Stephen Jay Gould
Image
Acquired characteristics are inherited in technology and culture. Lamarckian evolution is rapid and accumulative. It explains the cardinal difference between our past, purely biological mode of change, and our current, maddening acceleration toward something new and liberating- or toward the abyss.
Stephen Jay Gould
Image
The essence of Darwinism lies in its claim that natural selection creates the fit. Variation is ubiquitous and random in direction. It supplies raw material only. Natural selection directs the course of evolutionary change.
Stephen Jay Gould
Image
Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress.
Stephen Jay Gould
Image
We live in an essential and unresolvable tension between our unity with nature and our dangerous uniqueness. Systems that attempt to place and make sense of us by focusing exclusively either on the uniqueness or the unity are doomed to failure. But we must not stop asking and questing because the answers are complex and ambiguous.
Stephen Jay Gould
Image
Before Kuhn, most scientists followed the place-a-stone-in-the-bright-temple-of-knowledge tradition, and would have told you that they hoped, above all, to lay many of the bricks, perhaps even the keystone, of truth's temple. Now most scientists of vision hope to foment revolution. We are, therefore, awash in revolutions, most self-proclaimed.
Stephen Jay Gould
Image
Antiessentialist thinking forces us to view the world differently. We must accept shadings and continua as fundamental. We lose criteria for judgment by comparison to some ideal: short people, retarded people, people of other beliefs, colors, and religions are people of full status.
Stephen Jay Gould
Image
Orchids were not made by an ideal engineer they are jury-rigged from a limited set of available components.
Stephen Jay Gould
Image
Even the standard example of ancient nonsense - the debate about angels on pinheads - makes sense once you realize that theologians were not discussing whether five or eighteen would fit, but whether a pin could house a finite or an infinite number.

Guessing right for the wrong reason does not merit scientific immortality.
Stephen Jay Gould
Image
I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops.

Eternal vigilance, as they say, is the price of freedom. Add intellectual integrity to the cost basis.
Stephen Jay Gould
Image
We are the offspring of history, and must establish our own paths in this most diverse and interesting of conceivable universes—one indifferent to our suffering, and therefore offering us maximum freedom to thrive, or to fail, in our own chosen way.

Image
Wind back the tape of life to the early days of the Burgess Shale let it play again from an identical starting point, and the chance becomes vanishingly small that anything like human intelligence would grace the replay.

... each with its own beauty, and each with a story to tell.

So much of science proceeds by telling stories.

Natural selection is a theory of local adaptation to changing environments. It proposes no perfecting principles, no guarantee of general improvement

Ordinary speciation remains fully adequate to explain the causes and phenomenology of punctuation.
