was the result of the action of laws existent in matter,—an upheaving, a washing away, a hardening, a disintegrating through a period of time beyond the conception of man,—the theologians were forced to substitute periods for days. When the old walls which had circumscribed man's mind became so crumbled as to allow of egress, individuals broke through them and revelled in the freedom of intelligent thought. When these walls were demolished by those who had themselves erected them, they were leaped, in all directions, by ardent explorers; and naturalists, no longer restrained by tradition, rushed upon voyages of discovery into the teeming world before them.
For a while this emancipation exhausted itself in the contemplation of the physical world, and an inquiry into brute life. Speculations and theories might riot in a past which was a practical eternity. They had unlimited space wherein to project, backward, the structure of the universe. But this long-stretching past was to be peopled only by the lower orders of animal life. The rocks were found to be filled with stony remains of animals who perished when the sandstone, which built old crumbling castles, was sea-shore mud; the chalk hills which bore them were found to be made up of myriads of little creatures. These humble representatives of life might be, must be, credited with a remote antiquity. But man was not an animal. He was a being apart. Although he was liable to heat and cold, disease and death, although his body was made of the same materials as the brute's, and was subject to the same laws of life, he was invested with an individuality which separated him from them. For a while the old influence of theological rule held even these venturous explorers to the ancient landmarks of human origin. By and by, the same impulse which had before led men to examine the proofs of physical creation induced them to consider the evidence of their own advent upon earth. Certain Scriptural statements did not appear reconcilable with each other. Cain went forth and builded a city; and there were artificers in brass and iron. Now Cain was only one of two men when he went forth. Whence came the citizens of that early settlement, and how did they understand the production of brass, a composite metal? How was it that man always met man wherever he went on the globe? Five thousand years ago the varied races were known to be distinct as now, and yet man was formerly said to be but about six thousand years old. Could one thousand years have produced the changes then evident, while five thousand succeeding years have scarce altered these different races? These and many other difficulties led thinkers to question whether man might not look much farther back into the past for his origin, and whether the same laws which had governed the birth, continuance, and distribution of other animals were not always in action to produce in him kindred results. The old belief, that all men descended from one man, began to be shaken; and good, honest, faithful Christians expressed their doubts of the matter. It was surmised that they were created in numbers. The old idea, that animals were all created in individual pairs, was found to be incompatible with the discovery of animal remains, in profusion, in rocks which were mud ages before any Adam could have existed to give them Hebrew names. Then, breaking away from the theological bonds, there sprang into active thought men of far-reaching minds, who began a thorough reconstruction of the whole theory of creation. The handwriting on the wall was Natural Law. All creation, man included, was but the result of one undeviating, unceasing, eternal, all-pervading law, and the state of the universe at any given moment was the state of evolution which that universe exhibited. Behind this law was the great inscrutable Spirit-power.
The infinite number of varied, aggregated facts stored up by man's patient study of this universe are irrelevant here, in a sketch of the progressive advance of his knowledge of creation. Those who desire to examine the evidence which has led to this verdict must go over the records themselves, or accept, out of their own convictions, the result of the examination. To entirely comprehend the Darwinian idea, one should be, to a certain extent, familiar with the principles of science. In other words, he should know more or less of what Darwin knows. He should be familiar with the general results of man's study in the different branches of science. He need not be an astronomer, a physicist, a geologist, a zoölogist, a botanist; but he should have a general acquaintance with the results of the labors of those who are such. He should, to a certain extent, understand the workings of Natural Law.
This is the great battle-ground on which the struggle is now taking place. The point at issue is, whether the physical changes of the material world, the introduction, continuance, and variation of organized beings, are due to the direct, special intervention of Deity, or whether they are the results of primeval laws, inherent in matter, and out of whose workings spring the phenomena of nature. The adherents to the former opinion maintain that the Deity has created all animals individually, or in individual species, by direct action, apart from natural forces, and indeed by an interference therewith. The votaries of the latter deny special creation, and maintain that all animals are, like the rest of the universe, the results of forces acting through all time, producing, by their diverse changing influences, the variations which, as they have widened and strengthened, have resulted in the difference exhibited among animals. The first is the old traditional idea, having its foundation in belief, and drawing its support from the Scriptures. The last is the modern conviction, having its foundation in reason, and drawing its support from the study of nature. How are these differences among animate creatures—these wide contrasts of form, size, and habits—produced, if not by God's special creation? This is the question which Mr. Darwin and his school of thinkers are seeking to answer.
Some half a century ago, M. Lamarck, a French naturalist, propounded a theory which excited the derision of the whole world. He accounted for these variations by suggesting that, as any special want was felt by an animal, the body took on that structure which was required to relieve it. To give a broad illustration: if men needed to fly for the support of life, wings would gradually grow out from their shoulders. Ridiculous as this may be, it showed that thinkers were at that time endeavoring to account, on purely natural grounds, for what they considered natural, and not supernatural phenomena.
Some twenty years ago, a book made its appearance which startled the whole reading world, and caused as much dispute as Darwin has since done. This was "Vestiges of the Natural History of Creation." It was anonymous, and the author has never acknowledged it: to this day he is unknown. This book was learned and lucid. It was received with delight by those who were still looking for some explanation of animal origin on natural grounds; and was derided quite as much as Lamarck's work by the adherents to the old traditional belief. Scouted by the great majority of naturalists, who still clung with tenacity to the notions of their predecessors, stigmatized as atheistic and abominable by theologians, it was first read with eagerness, and then put aside; and though it went through many editions, it is now almost forgotten. But this book was the beginning of Darwinism. It says:—
"We have seen powerful evidence that the construction of this globe and its associates, and, inferentially, that of all the other globes in space, was the result, not of any immediate or personal exertion on the part of Deity, but of natural laws which are expressions of his will. What is to hinder our supposing that the organic creation is also the result of natural laws, which are in like manner an expression of his will?"
Referring to the Deity as the great motive-power of all the universe, the author says:—
"To a reasonable mind the Divine attributes must appear, not diminished or reduced in any way, by supposing a creation by law, but infinitely exalted. It is the narrowest of all views of the Deity, and characteristic of a humble class of intellects, to suppose him acting constantly in particular ways for particular occasions. It, for one thing, greatly detracts from his foresight,—the most undeniable of all the attributes of Omnipotence. It lowers him towards the level of our own humble intellects. Much more worthy of him it surely is to suppose that all things have been commissioned by him from the first, though neither is he absent from a particle of the current of natural affairs in one sense, seeing that the whole system is continually supported by his providence.... When all is seen to be the result of law, the idea of an Almighty author becomes irresistible, for the creation of a law for an endless series of phenomena—an act of intelligence above all else we can conceive—could have no other imaginable source, and tells, moreover, as powerfully for a sustaining as for an originating power."
He sums up the hypothesis which he seeks to sustain thus:—
"I suggest, then, as an hypothesis already countenanced by much that is ascertained, and likely to be further sanctioned by much that
