" Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

" When we no longer look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension; when we regard every production of nature as one which has had a history; when we contemplate every complex structure and instinct as the summing up of many contrivances, each useful to the possessor, nearly in the same way as when we look at any great mechanical invention as the summing up of the labour, the experience, the reason, and even the blunders of numerous workmen; when we thus view each organic being, how far more interesting, I speak from experience, will the study of natural history become! "

" Nothing at first can appear more difficult to believe than that the more complex organs and instincts should have been perfected, not by means superior to, though analogous with, human reason, but by the accumulation of innumerable slight variations, each good for the individual possessor. Nevertheless, this difficulty, though appearing to our imagination insuperably great, cannot be considered real if we admit the following propositions, namely,— that gradations in the perfection of any organ or instinct, which we may consider, either do now exist or could have existed, each good of its kind,— that all organs and instincts are, in ever so slight a degree, variable,— and, lastly, that there is a struggle for existence leading to the preservation of each profitable deviation of structure or instinct. The truth of these propositions cannot, I think, be disputed. "

" If about a dozen genera of birds had become extinct or were unknown, who would have ventured to have surmised that birds might have existed which used their wings solely as flappers, like the logger-headed duck (Micropterus of Eyton); as fins in the water and front legs on the land, like the penguin; as sails, like the ostrich; and functionally for no purpose, like the Apteryx. Yet the structure of each of these birds is good for it, under the conditions of life to which it is exposed, for each has to live by a struggle; but it is not necessarily the best possible under all possible conditions. It must not be inferred from these remarks that any of the grades of wing-structure here alluded to, which perhaps may all have resulted from disuse, indicate the natural steps by which birds have acquired their perfect power of flight; but they serve, at least, to show what diversified means of transition are possible.

" he importance and influence of Charles Darwin’s theory of evolution by natural selection can scarcely be exaggerated. A century after Darwin’s death, the great evolutionary biologist and historian of science, Ernst Mayr, wrote, ‘The worldview formed by any thinking person in the Western world after 1859, when On the Origin of Species was published, was by necessity quite different from a worldview formed prior to 1859… The intellectual revolution generated by Darwin went far beyond the confines of biology, causing the overthrow of some of the most basic beliefs of his age.’1 Adrian Desmond and James Moore, Darwin’s biographers, contend, ‘Darwin is arguably the best known scientist in history. More than any modern thinker—even Freud or Marx—this affable old-world naturalist from the minor Shropshire gentry has transformed the way we see ourselves on the planet.’2 In the words of the philosopher Daniel C. Dennett, ‘Almost no one is indifferent to Darwin, and no one should be. The Darwinian theory is a scientific theory, and a great one, but that is not all it is… Darwin’s dangerous idea cuts much deeper into the fabric of our most fundamental beliefs than many of its sophisticated apologists have yet admitted, even to themselves.’3 Dennett goes on to add, ‘If I were to give an award for the single best idea anyone has ever had, I’d give it to Darwin, ahead of Newton and Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, and purpose with the realm of space and time, cause and effect, mechanism and physical law.’4 The editors of the Cambridge Companion to Darwin begin their introduction by stating, ‘Some scientific thinkers, while not themselves philosophers, make philosophers necessary. Charles Darwin is an obvious case. His conclusions about the history and diversity of life—including the evolutionary origin of humans—have seemed to bear on fundamental questions about being, knowledge, virtue and justice.’5 Among the fundamental questions raised by Darwin’s work, which are still being debated by philosophers (and others) are these: ‘Are we different in kind from other animals? Do our apparently unique capacities for language, reason and morality point to a divine spark within us, or to ancestral animal legacies still in evidence in our simian relatives? What forms of social life are we naturally disposed towards—competitive and selfish forms, or cooperative and altruistic ones?’6 As the editors of the volume point out, virtually the entire corpus of the foundational works of Western philosophy, from Plato and Aristotle to Descartes to Kant to Hegel, has had to be re-examined in the light of Darwin’s work. Darwin continues to be read, discussed, interpreted, used, abused—and misused—to this day. As the philosopher and historian of science, Jean Gayon, puts it, ‘[T]his persistent positioning of new developments in relation to a single, pioneering figure is quite exceptional in the history of modern natural science.
