“ The key to all philosophy lies in the clear apprehension of Berkeley's problem—which is neither more nor less than one of the shapes of the greatest of all questions, 'What are the limits of our faculties?' And it is worth any amount of trouble to comprehend the exact nature of the argument by which Berkeley arrived at his results, and to know by one's own knowledge the great truth which he discovered—that the honest and rigorous following up of the argument which leads us to materialism inevitably carries us beyond it. ”

“ Are we, and the Cosmos of which we are a part, the sport of changeable and capricious deities, the pawns in a game of the gods, as some of the Greeks held; or of a power drunkenly malicious, as Heine once cynically suggested; or a battle-ground for a force of good and a force of evil as in so many Eastern religions? Are we dominated by pure evil, as some dark creeds have held, or by pure good, as the religion of the Western world teaches? And if we are dominated by pure evil, whence come good and the idea of good, or, if by pure good, whence evil and the idea of evil? ”

“ It is with this intent that I have subordinated any reasonable or unreasonable ambition for scientific fame which I may have permitted myself to entertain to other ends; to the popularisation of science; to the development and organisation of scientific education; to the endless series of battles and skirmishes over evolution; and to untiring opposition to that ecclesiastical spirit, that clericalism, which in England, as everywhere else, and to whatever denomination it may belong, is the deadly enemy of science. ”

“ Who shall count the host of weaker men whose sense of truth has been destroyed in the effort to harmonise impossibilities—whose life has been wasted in the attempt to force the generous new wine of science into the old bottles of Judaism, compelled by the outcry of the same strong party? It is true that if philosophers have suffered, their cause has been amply avenged. Extinguished theologians lie about the cradle of every science as the strangled snakes beside that of Hercules ”

“ In a well-worn metaphor a parallel is drawn between the life of man and the metamorphosis of a caterpillar into a butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shews that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. ”

“ To say, therefore, in the admitted absence of evidence, that I have any belief as to the mode in which the existing forms of life have originated, would be using words in a wrong sense. But expectation is permissible where belief is not; and if it were given me to look beyond the abyss of geologically recorded time to the still more remote period when the earth was passing through physical and chemical conditions which it can no more see again than a man can recall his infancy, I should expect to be a witness of the evolution of living protoplasm from non-living matter. ”

“ As we have tried to shew in the preceding chapter, biological science was partially prepared; the mutability of species and the orderly succession of organic life were in the air. But the application of the doctrine to man came as a greater shock to civilised sentiment than would have occurred a century earlier. It came as a disaster even to the clearest and calmest intellects, for it seemed to drag down to the dirt the nobility of man. Out of the fierce flame of the French Revolution, there had come purged and clean the conception of man as an individual and soul. ”

“ When the experience of generation after generation is recorded, and a single book tells us more than Methuselah could have learned, had he spent every waking hour of his thousand years in learning; when apparent disorders are found to be only the recurrent pulses of a slow-working order, and the wonder of a year becomes the commonplace of a century; when repeated and minute examination never reveals a break in the chain of causes and effects; and the whole edifice of practical life is built upon our faith in its continuity ”

“ As this century advanced, the conception of the dignity and worth of each individual man, rich or poor, bond or free, had spread more and more widely, bearing as its fruit the emancipation of slaves, the spread of political freedom, the amelioration of the conditions of the dregs of humanity, the right of all to education, the possibility of universal peace based on the brotherhood of man; and all that was best in philosophy and in political practice seemed bound up with a lofty view of the unit of mankind. ”

“ Whatever may be the ultimate fate of the particular theory put forth by Darwin, I venture to affirm that, so far as my knowledge goes, all the ingenuity and all the learning of hostile critics has not enabled them to adduce a solitary fact of which it can be said that it is irreconcilable with the Darwinian theory. In the prodigious variety and complexity of organic nature, there are multitudes of phenomena which are not deducible from any generalisation we have yet reached. ”

“ The development of exact natural knowledge in all its vast range, from physics to history and criticism, is the consequence of the working out, in this province, of the resolution to take nothing for truth without clear knowledge that it is such; to consider all beliefs open to criticism; to regard the value of authority as neither greater nor less than as much as it can prove itself to be worth. The modern spirit is not the spirit 'which always denies,' delighting only in destruction ”

“ To most of us it seems of sufficient importance and of sufficient difficulty to make our decisions in the little eddies of good and evil that form as the world-stream breaks round our individual lives. Huxley strove to interpret the world-stream itself, to translate its movements into the ethical language of man. As knowledge of the forces and movements of the Cosmos has increased so has our general conception been intensified, our conception of it as a wondrous display of power and grandeur and superhuman fixity of order. But are the forces of the Cosmos good or evil? ”

“ My regular school training was of the briefest, perhaps fortunately: for, though my way of life has made me acquainted with all sorts and conditions of men, from the highest to the lowest, I deliberately affirm that the society I fell into at school was the worst I have ever known. We boys were average lads with much the same inherent capacity for good and evil as any others; but the people who were set over us cared about as much for our intellectual and moral welfare as if they were baby-farmers. ”

“ The year 1859, the date of publication of The Origin of Species, is a momentous date in the history of this century, as it was the year in which there was given to the world a theory that not only revolutionised scientific opinion, but altered the trend of almost every branch of thought. To understand this great change, and the part played in it by Huxley, it is necessary to be quite clear as to what Darwin did. In the first place, he did not invent evolution. ”

“ That principle is of great antiquity; it is as old as Socrates; as old as the writer who said, 'Try all things, hold fast by that which is good'; it is the foundation of the Reformation, which simply illustrated the axiom that every man should be able to give reason for the faith that is in him; it is the great principle of Descartes; it is the fundamental axiom of modern science. Positively the principle may be expressed: In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration. ”

“ To promote the increase of natural knowledge and to forward the application of scientific methods of investigation to all the problems of life to the best of my ability, in the conviction which has grown with my growth and strengthened with my strength, that there is no alleviation for the sufferings of mankind except veracity of thought and of action, and the resolute facing of the world as it is when the garment of make-believe by which pious hands have hidden its uglier features is stripped off. ”

“ But, the more profoundly does the conception of evolution lay hold of human thought, the more inevitable it becomes to recognise that man and all that is best in man—his aspirations, ideas, virtues, and practical and abstract justice and goodness—are just as much the product of the cosmic process and part of the Cosmos as the most sinister results of the struggle for existence. ”

“ The great mass of mankind have neither the liking, nor [203] the aptitude, for either literary or scientific or artistic pursuits; nor, indeed, for excellence of any sort. Their ambition is to go through life with moderate exertion and a fair share of ease, doing common things in a common way. And a great blessing and comfort it is that the majority of men are of this mind; for the majority of things to be done are common things, and are quite well enough done when commonly done. The great end of life is not knowledge but action. ”

“ They were impelled by a driving force which distinguishes the successful man from the muddler and without which the finest mental powers are as useless as a complicated machine disconnected from its driving-wheel. They were directed by a lofty and disinterested enthusiasm, without which the most talented man is a mere self-seeker, useless or dangerous to society. The faculties and qualities which made Huxley great as a zoölogist were practically those which he applied to the general questions of biological theory, to the problems of education and of society, and to philosophy and metaphysics. ”

“ A thousand causes have been contributory; but among these causes two have been of extraordinary importance—an idea and a man. The idea is the conception of organic evolution, and the man was Huxley. The idea of evolution clothed [169] the dead bones of anatomy with a fair and living flesh, and the new body left the dusty corners of museums to pervade the world, arousing the attention and interest of all. A large part of the prodigious mental activities of Huxley was devoted to compelling the world to take an interest in biological science. ”

“ By such a method of work alone he believed it possible to distinguish what we believe on authority from what we have convinced ourselves to be true, and, as we shall see later, he regarded it as the most important duty of a man to have acquired the habit of classifying the mass of ideas in his brain into those which he knew and those which he thought to be true from having read or heard or imagined them. ”

“ As a matter of fact, in the business of life we have to act differently. A large proportion of our opinions, beliefs, and reasons for conduct must come to us on the authority of others. We have no direct experience of the past; of the present we can see little and only the little immediately surrounding us. In a multitude of affairs we have to act on authority, to accept from books or from persons what we have not ourselves the opportunity of knowing. ”

“ Well, which is the most rational theory about these ten millions of species? Is it most likely that there have been ten millions of special creations; or is it most likely that by continual modifications, due to change of circumstances, ten millions of varieties have been produced, as varieties are being produced still?... Even could the supporters of the development hypothesis merely shew that the origination of species by the process of modification is conceivable, they would be in a better position than their opponents. ”

“ In the early part of the century, the discoveries of geologists had been the occasion of great distress to those good people who clung to a literal interpretation of everything in the Bible. Long before the doctrine of evolution and the descent of man from lower animals had taken practical shape, there had been a battle royal between geologists who declared that the earth was many million years old, and had been inhabited at least by animals and plants for enormous periods, and those who clung to the traditional chronology which placed the date of creation only a few thousand years from now. ”

“ Darwin's views, it is our clear conviction that, as the evidence stands, it is not absolutely proven that a group of animals having all the characters exhibited by species in nature, has ever been originated by selection, whether natural or artificial. Groups having the morphological character of species, distinct and permanent races, in fact, have been so produced over and over again; but there is no positive evidence at present that any group of animals has, by variation and selective breeding, given rise to another group which was in the least degree infertile with the first. ”

“ This view was evidently that also of Darwin himself, who thus concluded his chapter on the struggle for existence: "When we reflect on this struggle, we may console ourselves with the full belief that the war of nature is not incessant, that no fear is felt, that death is generally prompt, and that the vigorous, the healthy, and the happy survive and multiply." As for man himself, though it be true that in him the consummation of pain is reached, still this is no isolated fact of far-reaching ethical importance. ”

“ It was to those who made the latter choice that he would entrust the teaching of the sciences underlying medicine; partly because from the mere mechanical reason of time these men would be better able to keep pace with the most recent advances in knowledge, and partly because their teaching would be stimulated by their own work in advancing knowledge. In this great matter the world is rapidly advancing towards the standard of Huxley; as each new appointment is made it becomes more and more probable that the man chosen will be a teacher and investigator rather than a practitioner. ”

“ But, however he work arduously or through long years, he can visit only the smallest portion of the field of nature in which he is working. It is necessary for him to employ the work of others, submitting, from time to time such accepted work to the tests suggested by his own observations. He learns to regard in a different light all knowledge taken on the authority of others; to distrust it a little until he has learned to weigh its general credibility by his own standards, and its particular credibility by subjecting portions of it to his own tests ”

“ In the days of Huxley's greatest activity, while by the natural force of events and by his special efforts science was becoming more and more recognised as a necessary and important branch of general education, the cry was raised against it that scientific education was not capable of giving what is called culture. A scientific man was regarded as a mere scientific specialist, and science was considered to have no place in, and in fact to be an enemy of, "liberal education." ”
