"The underlying reason for convergence seems to be that all organisms are under constant scrutiny of natural selection and are also subject to the constraints of the physical and chemical factors that severely limit the action of all inhabitants of the biosphere. Put simply, convergence shows that in a real world not all things are possible."

“It seldom seems to strike the ultra-Darwinists that theology might have its own richness and subtleties, and might—strange thought—actually tell us things about the world that are not only to our real advantage, but will never be revealed by science.”

“If one compares the sequence of amino acids that go to form the protein haemoglobin, it becomes apparent that humans and chimps are identical and do not differ in a single site ...”

“The long history of mankind is studded with convergences, perhaps most notably in social systems and the use of artefacts and technology. But for human history, set in the arrow of time, there appears to be one intolerable stumbling-block. This is the catastrophic failure in human values and decency.”

“... not only that, but it can instruct us as to what may be the limits of desirable knowledge and risks of unbridled curiosity. This world-picture could also show that far from being a series of mindless accidents, history has directions and conceivably end-points.”

“The relative moral merits of any of us are in the final analysis only relevant to exponents of the theistic world picture; to those of scientistic inclination they might be socially useful but in the grand order of things can have no meaning in a soulless world.”

“Again and again Gould has been seen to charge into battle, sometimes hardly visible in the struggling mass. Strangely immune to seemingly lethal lunges he finally re-emerges. Eventually the dust and confusion die down. Gould announces to the awestruck onlookers that our present understanding of evolutionary processes is dangerously deficient and the theory is perhaps in its death throes. We look beyond the exponent of doom, and there standing in the sunlight is the edifice of evolutionary theory, little changed.”
