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

More quotes by 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
With copious evidence ranging from Plato's haughtiness to Beethoven's tirades, we may conclude that the most brilliant people of history tend to be a prickly lot.
Stephen Jay Gould
Image
The only universal attribute of scientific statements resides in their potential fallibility. If a claim cannot be disproven, it does not belong to the enterprise of science.
Stephen Jay Gould
Image
The journalistic tradition so exalts novelty and flashy discovery, as reputable and newsworthy, that standard accounts for the public not only miss the usual activity of science but also, and more unfortunately, convey a false impression about what drives research.
Stephen Jay Gould
Image
All interesting issues in natural history are questions of relative frequency, not single examples. Everything happens once amidst the richness of nature. But when an unanticipated phenomenon occurs again and again—finally turning into an expectation—then theories are overturned.
Stephen Jay Gould
Image
The literal record was not a hopelessly and imperfect fraction of truly insensible gradation within large populations but an accurate reflection of the actual process identified by evolutionists as the chief motor of biological change. The theory of punctuated equilibrium was, in its initial formulation, little more than this insight adumbrated.
Stephen Jay Gould
Image
If evolution almost always occurs by rapid speciation in small, peripheral isolates, then what should the fossil record look like? We are not likely to detect the event of speciation itself. It happens too fast, in too small a group, isolated too far from the ancestral range.
Stephen Jay Gould
Image
Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
Stephen Jay Gould
Image
Paleontologists [fossil experts] have paid an exorbitant price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we almost never see the very process we profess to study.
Stephen Jay Gould
Image
No one should feel at all offended or threatened by the obvious fact that we are not all born entirely blank, or entirely the same, in our mixture of the broad behavioral propensities defining what we call temperament.
Stephen Jay Gould
Image
In what I like to call the Great Asymmetry, every spectacular incident of evil will be balanced by 10,000 acts of kindness, too often unnoted and invisible.
Stephen Jay Gould
Image
We are glorious accidents of an unpredictable process with no drive to complexity, not the expected results of evolutionary principles that yearn to produce a creature capable of understanding the mode of its own necessary construction.
Stephen Jay Gould
Image
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.
Stephen Jay Gould
Image
We are the accidental result of an unplanned process ... the fragile result of an enormous concatenation of improbabilities, not the predictable product of any definite process.

Mary Anning [is] probably the most important unsung (or inadequately sung) collecting force in the history of paleontology.

Image
Charles Darwin viewed the fossil record more as an embarrassment than as an aid to his theory.
Stephen Jay Gould
Image
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.

The enemy of knowledge and science is irrationalism, not religion
Stephen Jay Gould
Image
The contingency of history (both for life in general and for the cultures of Homo sapiens ) and human free will (in the factual rather than theological sense) are conjoined concepts, and no better evidence can be produced than the experimental production of markedly different solutions in identical environments.

I picture several reviewers of my own books as passing a long future lodged between Brutus and Judas in the jaws of Satan.
