“ Without him we should have had, not only evolutionism, but also, as Wallace's discovery testifies, natural selection itself into the bargain. But we should never have had the 'Origin of Species.' We should never have had that vast and enthusiastic consensus of scientific opinion through an all but unanimous thinking world, which has forced an immediate acceptance of evolutionary ideas down the unwilling throats of half unthinking Europe. ”

“ What is now the general creed, more or less loosely held and imperfectly understood, of hundreds and thousands among the intelligent mass, would, under such circumstances, be even yet the mere party-shibboleth of an esoteric few, struggling hard against the bare force of overwhelming numbers to ensure not only recognition but a fair hearing for the first principles of the development theory. It is to Darwin, and to Darwin almost alone, that we owe the present comparatively wide acceptance of the all-embracing doctrine of evolution. ”

“ Furthermore, it would give us creatures without special adaptation of any kind to the peculiar circumstances of their own environment. To account for adaptation, for the almost perfect fitness of every plant and every animal to its position in life, for the existence (in other words) of definitely correlated parts and organs, we must call in the aid of survival of the fittest. Without that potent selective agent, our conception of the becoming of life is a mere chaos; order and organisation are utterly inexplicable save by the brilliant illuminating ray of the Darwinian principle. ”

“ With my mind thus prepared I fortunately happened to read Malthus's "Essay on Population" and the idea of natural selection through the struggle for existence at once occurred to me. Of all the subordinate points in the theory, the last which I understood was the cause of the tendency in the descendants from a common progenitor to diverge in character.'
It is impossible, indeed, to overrate the importance of Malthus, viewed as a schoolmaster to bring men to Darwin, and to bring Darwin himself to the truth. ”

“ The elegance of the grasses, the novelty of the parasitical plants, the beauty of the flowers, the glossy green of the foliage, but above all the general luxuriance of the vegetation, filled me with admiration.' In truth, among those huge buttressed trunks, overhung by the unbroken canopy of foliage on the vast spreading and interlacing branches, festooned with lianas and drooping lichens, or beautified by the pendent alien growth of perfumed orchids, Darwin's mind must indeed have found congenial food for apt reflection, and infinite opportunities for inference and induction. ”

“ Why was it that the 'Origin of Species' possessed this extraordinary vitalising and kinetic power, this germinal energy, this contagious force, beyond all other forms of evolutionism previously promulgated? Why did the world, that listened so coldly to Lamarck and Chambers, turn so ready an ear to Charles Darwin and natural selection? Partly, no doubt, because in the fulness of time the moment had come and the prophet had arisen. All great movements are long brewing, and burst out at last (like the Reformation and the French Revolution) with explosive energy. ”

“ And evolutionism is gradually though slowly filtering downward. It is permeating the daily press of the nations, and gaining for its vocabulary a recognised place in the phraseology of the unlearned vulgar. Such expressions as 'natural selection,' 'survival of the fittest,' 'struggle for existence,' 'adaptation to the environment,' and all the rest of it, are becoming as household words upon the lips of thousands who only know the name of Darwin as a butt for the petty empty jibes of infinitesimal cheap witlings. ”

“ To some among us still, as to Lyell before us, this new belief in the animal origin of man seems far less beautiful, noble, and inspiriting than the older faith in his special and separate divine creation. Such thinkers find it somehow more pleasant and comfortable to suppose that man has fallen than that man has risen; the doctrine of the universal degradation of humanity paradoxically appears to them more full of promise and aspiration for the times to come than the doctrine of its universal elevation. To Darwin himself, however, it seemed otherwise. ”

“ Our starved little northern fauna and flora, the mere leavings of the vast ice sheets that spread across our zone in the glacial epoch, show us a world depopulated of all its largest, strangest, and fiercest creatures; a world dwarfed in all its component elements, and immensely differing in ten thousand ways from that rich, luxuriant, over-stocked hot-house in which the first great problems of evolution were practically worked out by survival of the fittest. ”

“ To Linnæus, the species into which he mapped out all the plants and animals then known, appeared as the descendants each of a solitary progenitor or of a primitive couple, called into existence at the beginning of all things by the direct fiat of a designing Creator. He saw the world of organic life as composed of so many well-demarcated types, each separate, distinct, and immutable, each capable of producing its like ad infinitum, and each unable to vary from its central standard in any of its individuals, except perhaps within very narrow and unimportant limits. ”

“ The main central body of all, retreating ever within as it dropped in its course the raw material of the planetary masses, has formed, at last, the sun, the great ruler and luminary of our system. Much as this primitive evolutionary concept of the development and history of the solar system has been modified and altered of late years by recent researches into the nature of comets and meteors and of the sun's surface, it still remains for all practical purposes of popular exposition the best and simplest mental picture of the general type of astronomical evolution. ”

“ In short, even without Charles Darwin, the nineteenth century would not have stood still; it would have followed in the wake of Buffon and Diderot, of Lamarck and Laplace, of St. Hilaire and Goethe, of Kant and Herschel, of Hutton and Lyell, of Malthus and of Spencer. The great world never rolls down the abysses of time obedient to the nod of one single overruling Titanic intellect. 'If the doctrine of evolution had not existed,' says Huxley, 'palæontologists must have invented it.'
But Charles Darwin acted, nevertheless, the part of an immense and powerful accelerating energy. ”

“ Whoever wishes to learn the full profundity of Darwin's researches, into every point that he set himself to investigate, cannot do better than turn for a while to the consideration of that exquisite treatise on one of the quaintest fairylands of science. He will there learn by what an extraordinary wealth of cunning devices natural selection has ensured the due conveyance of the fecundating pollen from stamens to stigmas within the limits of a single group of vegetable organisms. ”

“ Inquiry was especially everywhere rife as to the origin and nature of specific distinctions among plants and animals. Those who believed in the doctrine of Buffon and of the 'Zoonomia' and those who disbelieved in it, alike, were profoundly interested and agitated in soul by the far-reaching implications of that fundamental problem. On every side evolutionism, in its crude form, was already in the air. Long before Charles Darwin himself published his conclusive 'Origin of Species,' every thinking mind in the world of science, elder and younger, was deeply engaged upon the self-same problem. ”

“ It was well indeed that Darwin began by publishing the shorter and more manageable abstract; the half, as the wise Greek proverb shrewdly remarks, is often more than the whole; and a world that eagerly devoured the first great deliverance of the Darwinian principle, might have stood aghast had it been asked to swallow it piecemeal in such gigantic treatises as those with which its author afterwards sought thrice to vanquish all his foes and thrice to slay the slain. ”

“ He may, no doubt, work at the details of his subject; he may be useful in adding to its facts; he will never be able to enlarge its philosophy. For the philosophy of every department depends on its connection with other departments, and must therefore be sought at their points of contact. It must be looked for in the place where they touch and coalesce: it lies, not in the centre of each science, but on the confines and margin.' This profound truth Darwin fully and instinctively realised. ”

“ To most people Darwinism and evolution mean one and the same thing. After what has here been said, however, with regard to the pre-Darwinian evolutionary movement, and the distinction between the doctrines of descent with modification and of natural selection, it need hardly be added that the two are quite separate and separable in thought, even within the limits of the purely restricted biological order. Darwinism is only a part of organic evolution; the theory, as a whole, owes much to Darwin, but it does not owe everything to him alone. ”

“ The thunder of the great European upheaval had grown silent at Waterloo when he was barely six years old, and his boyhood was passed amid country sights and sounds during that long period of reconstruction and assimilation which followed the fierce volcanic outburst of the French Revolution. Happy in the opportunity of his birth, he came upon the world eight years after the first publication of Lamarck's remarkable speculations, and for the first twenty-two years of his life he was actually the far younger contemporary of the great French evolutionary philosopher. ”

“ Charles Darwin was a great man, and he accomplished a great work. The Newton of biology, he found the science of life a chaotic maze; he left it an orderly system, with a definite plan and a recognisable meaning. Great men are not accidents; great works are not accomplished in a single day. Both are the product of adequate causes. The great man springs from an ancestry competent to produce him; he is the final flower and ultimate outcome of converging hereditary forces, that culminate at last in the full production of his splendid and exceptional personality. ”

“ Observation and collection had given him one half the subject-matter of the 'Origin of Species;' reflection and Malthus were to give him the other half. Never had great mind a nobler chance; never, again, had noble chance a great mind better adapted by nature and heredity to make the most of it. The man was not wanting to the opportunity, nor was the opportunity wanting to the man. Organism and environment fell together into perfect harmony ”

“ Evolutionism, as now commonly understood, may be fairly regarded as a mode of envisaging to ourselves the history of the universe, a tendency or frame of mind, a temperament, one might almost say, or habit of thought rather than a definite creed or body of dogmas. The evolutionist looks out upon the cosmos as a continuous process unfolding itself in regular order in obedience to definite natural laws. ”

“ It showed that every part of every plant and every animal existed primarily for the sake of that plant or animal alone; it unseated man from his imaginary throne in the centre of the cosmos, teaching him at once a lesson of humility and a lesson of aspiration—pointing out to him how low was the origin from which, in very truth, he first sprang, and suggesting to him, at the same time, how high was the grand and glorious destiny to which by his own strenuous and ardent efforts he might yet perchance some day attain. ”

“ In his earlier years at Down, the quiet Kentish home was constantly enlivened by the visits of men like Lyell, Huxley, Hooker, Lubbock, and Wollaston. During his later days, it was the Mecca of a world-wide scientific and philosophic pilgrimage, where all the greatest men our age has produced sought at times the rare honour of sitting before the face of the immortal master. But to the very last Darwin himself never seemed to discover that he was anything more than just an average man of science among his natural peers. ”

“ All these diverse lines of thought both showed the wide-spread influence of Darwin's first great work, and led up to the preparation of his second, in which he dealt with the history and development of the human race. And what was thus true of England was equally true of the civilised world, regarded as a whole: everywhere the great evolutionary movement was well in progress; everywhere the impulse sent forth from that quiet Kentish home was permeating and quickening the entire pulse of intelligent humanity. ”

“ The rich alluvial silt of mighty river systems, the immemorial manuring of the virgin soil, the fierce energy of an almost equatorial sun, and the universal presence of abundant water, combine to make life in that marvellous region unusually wealthy, varied, and crowded, so that the struggle for existence is there perhaps more directly visible to the seeing eye than in any other known portion of God's universe. ”

“ Surely it is a nobler view of life that we may yet by our own strenuous exertions raise our race some places higher in the endless and limitless hierarchy of nature than that we are the miserable and hopelessly degenerate descendants of a ruined and degraded angelic progenitor. Surely it is well, while we boast with Glaucus that we indeed are far braver and better than our ancestors, to pray at the same time, in the words of Hector, that our sons may be yet braver and better than ourselves. ”

“ For the general acceptance of Darwin's theory, which we may watch progressing around us every minute to-day, implies a complete bouleversement of anthropocentric ideas, a total change in our human conception of our own relations to the world and the universe, which must work out for ever increasingly wide-reaching and complex effects in all our dealings with one another and with the environment at large. ”

“ On the other hand, the total esoteric philosophic conception of evolution as a cosmical process, one and continuous from nebula to man, from star to soul, from atom to society, we owe rather to the other great prophet of the evolutionary creed, Herbert Spencer, whose name will ever be equally remembered side by side with his mighty peer's, in a place of high collateral glory. ”

“ A group of tiny volcanic islets, never joined to any land, nor even united to one another, yet each possessing its own special zoological features—the Galapagos roused to an extraordinary degree the irresistible questionings of Darwin's mind. They contain no frogs, and no mammal save a mouse, brought to them, no doubt, by some passing ship. The only insects are beetles, which possess peculiar facilities for being transported in the egg or grub across salt water upon floating logs. ”

“ Before Copernicus, the earth stood fixed and immovable in the centre of the universe, with obsequious suns, and planets, and satellites dancing attendance in cycle and epicycle around the solid mass, to which by day and night they continually ministered. The great astronomical revolution begun by Copernicus, Galileo, and Kepler, and completed by Newton, Laplace, and Herschel, reduced the earth to its true position as a petty planet, revolving feebly among its bigger brethren round a petty sun, in some lost corner of a vast, majestic, and almost illimitable galaxy. ”

“ A powerful, robust, athletic man, in florid health and of temperate habits, yet with the full-blooded tendency of the eighteenth century vividly displayed in his ample face and broad features, Erasmus Darwin bubbled over with irrepressible vivacity, the outward and visible sign of that overflowing energy which forms everywhere one of the most marked determining conditions of high genius. ”

“ For, in the first place, Darwin had to deal with the science of life, the science where the opposition to evolutionism was sure to be strongest, and where the forces and tendencies in favour of obscurantism were sure to gather in fullest force. Every other great onward step in our knowledge of our own relation to the universe of which we form a part had been compelled indeed to run the gauntlet, in its own time, of ecclesiastical censure and of popular dislike. ”

“ Even upon the far less abstruse and hypothetical question, whether all life took its prime origin from a single starting-point or from several distinct and separate tribal ancestors, he hardly cared so much as to hazard a passing speculation. With splendid self-restraint he confined his attention almost entirely to the more manageable and practical problem of the origin of species by natural selection, which lay then and there open for solution before him. ”

“ How the first organism came to exist biology has not yet been able fully to explain for us; but aided by chemical science it has been able to show us in part how some of the simpler organic bodies may have been originally built up, and it does not despair of showing us in the end how the earliest organism may actually have been produced from the prime elements of oxygen, hydrogen, nitrogen, and carbon. Into this most fundamental of biological problems, however, Darwin himself, with his constitutional caution and dread of speculative theorising, was not careful or curious to enter. ”
