Leonardo's Mountain of Clams and the Diet of Worms: Essays on Natural History Quotes

“Darwinian evolution may be the most truthful and powerful idea ever generated by Western Science, but if we continue to illustrate our conviction with an indefensible, unsupported, entirely speculative, and basically rather silly story, then we are clothing a thing of beauty in rags - and we should be ashamed, "for the apparel oft proclaims the man.”

“Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.”

“If we choose a weak and foolish speculation as a primary textbook illustration (falsely assuming that the tale possesses a weight of history and a sanction of evidence), then we are in for trouble - as critics properly nail the particular weakness, and then assume that the whole theory must be in danger if supporters choose such a fatuous case as a primary illustration.”

“No one supposed that dinoflagellates might actively kill fish as an evolved response for their own specific advantage, including a potential nutritional benefit for the algal cells. And yet the dinoflagellates do seem to be killing and eating fishes in a manner suggesting active evolution for this most peculiar reversal.”

“I am not, personally, a believer or a religious man in any sense of institutional commitment or practice. But I have a great respect for religion, and the subject has always fascinated me, beyond almost all others (with a few exceptions, like evolution and paleontology).”

“As a chief ingredient in the mythology of science, the accumulation of objective facts supposedly controls the history of conceptual change–as logical and self-effacing scientists bow before the dictates of nature and willingly change their views to accommodate the growth of conceptual knowledge. The paradigm for such an idealistic notion remains Huxley’s famous remark about “a beautiful theory killed by a nasty, ugly little fact.” But single facts almost never slay worldviews, at least not right away (and properly so, for the majority of deeply anomalous observations turn out to be wrong)... Anomalous facts get incorporated into existing theories, often with a bit of forced stretching to be sure, but usually with decent fit because most worldviews contain considerable flexibility. (How else could they last so long, or be so recalcitrant to overthrow?)”
