More quotes by Stephen Jay Gould

Image
At a minimum, in explaining evolutionary pathways through time, the constraints imposed by history rise to equal prominence with the immediate advantages of adaptation.
Stephen Jay Gould
Image
In their recently aborted struggle to inject Genesis literalism into science classrooms, fundamentalist groups followed their usual opportunistic strategy of arguing two contradictory sides of a question when a supposed rhetorical advantage could be extracted from each.
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
Science simply cannot adjudicate the issue of God's possible superintendence of nature.
Stephen Jay Gould
Image
Evolution has encountered no intellectual trouble no new arguments have been offered. Creationism is a home-grown phenomenon of American sociocultural history-a splinter movement ... who believe that every word in the Bible must be literally true, whatever such a claim might mean.
Stephen Jay Gould
Image
The telephone is the greatest single enemy of scholarship for what our intellectual forebears used to inscribe in ink now goes once over a wire into permanent oblivion.
Stephen Jay Gould
Image
I picture several reviewers of my own books as passing a long future lodged between Brutus and Judas in the jaws of Satan.

Image
Words change their meanings, just as organisms evolve. We would impose an enormous burden on our economy if we insisted on payment in cattle every time we identified a bonus as a pecuniary advantage (from the Latin pecus , or cattle, a verbal fossil from a former commercial reality).
Stephen Jay Gould
Image
Without a commitment to science and rationality in its proper domain, there can be no solution to the problems that engulf us. Still, the Yahoos never rest.
Stephen Jay Gould
Image
It is the things we think we know - because they are so elementary or because they surround us - that often present the greatest difficulties when we are actually challenged to explain them.
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
Scientists have power by virtue of the respect commanded by the discipline... We live with poets and politicians, preachers and philosophers. All have their ways of knowing, and all are valid in their proper domain. The world is too complex and interesting for one way to hold all the answers.
Stephen Jay Gould
Image
Guessing right for the wrong reason does not merit scientific immortality.
Stephen Jay Gould
Image
Memory is a fascinating trickster. Words and images have enormous power and can easily displace actual experience over the years.
Stephen Jay Gould
Image
My own field of paleontology has strongly challenged the Darwinian premise that life's major transformations can be explained by adding up, through the immensity of geological time, the successive tiny changes produced generation after generation by natural selection.
Stephen Jay Gould
Image
We cannot win this battle to save species and environments without forging an emotional bond between ourselves and nature as well - for we will not fight to save what we do not love.
Stephen Jay Gould
Image
I love the wry motto of the Paleontological Society, meant both literally and figuratively, for hammers are the main tool of our trade: Frango ut patefaciam - I break in order to reveal.

Evolution is a process of constant branching and expansion.

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.

Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
