"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)."
"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."
"We may need simple and heroic legends for that peculiar genre of literature known as the textbook. But historians must also labor to rescue human beings from their legends in science if only so that we may understand the process of scientific thought aright."
"No one-liner can ever be optimal."
"Theory-free science makes about as much sense as value-free politics."
"A complete theory of evolution must acknowledge a balance between "external" forces of environment imposing selection for local adaptation and "internal" forces representing constraints of inheritance and development. Vavilov placed too much emphasis on internal constraints and downgraded the power of selection. But Western Darwinians have erred equally in practically ignoring (while acknowledging in theory) the limits placed on selection by structure and development what Vavilov and the older biologists would have called "laws of form."
"Rifkin's assertions bear no relationship to what I have observed and practiced for 25 years ... Either I am blind or he is wrong - and I think I can show, by analyzing his slipshod scholarship and basic misunderstanding of science, that his world is an invention constructed to validate his own private hopes ... Rifkin shows no understanding of the norms and procedures of science: he displays little comprehension of what science is and how scientists work."
"If any issue should unite liberals and conservatives, anyone who cares about the integrity of human achievement or respect for human accomplishment, may we not all pledge to avoid the silly censoring that can lead to a codification of Orwell's Newspeak? Consider John Milton's reasons for why good arguments are often lost: 'For want of words, no doubt, or lack of breath!'"
"Heydrich, Eichmann, and company therefore invoke the usual trick of argument for breaking a true continuum that lacks a compelling point for separation: choose an arbitrary dividing line and then treat it as a self-evident law of nature."
"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 board transported its jurisdiction to a never-never land where a Dorothy of the new millennium might exclaim: "They still call it Kansas, but I don't think we're in the real world anymore.""
"The world is too complex for subsumption under any general theory of change."
"Precise adaptation, with each part finely honed to perform a definite function in an optimal way, can only lead to blind alleys, dead ends, and extinction."
"The basic formulation, or bare-bones mechanics, of natural selection is a disarmingly simple argument, based on three undeniable facts (overproduction of offspring, variation, and heritability) and one syllogistic inference (natural selection, or the claim that organisms enjoying differential reproductive success will, on average, be those variants that are fortuitously better adapted to changing local environments, and that these variants will then pass their favored traits to offspring by inheritance)."
"...we must be wary of granting too much power to natural selection by viewing all basic capacities of our brain as direct adaptations."
"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."
"Sigmund Freud often remarked that great revolutions in the history of science have but one common, and ironic, feature: they knock human arrogance off one pedestal after another of our previous conviction about our own self-importance."
"No rational order of divine intelligence unites species. The natural ties are genealogical along contingent pathways of history."
"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."
"Good scholars struggle to understand the world in an integral way (pedants bite off tiny bits and worry them to death). These visions of reality [...] demand our respect, for they are an intellectual's only birthright. They are often entirely wrong and always flawed in serious ways, but they must be understood honorably and not subjected to mayhem by the excision of patches."
