According to Moses' solution of the question (in the dispute with whom the entire significance of this theory lies), it appears that the diversity of the species of living creatures proceeded according to the will of God, and according to His almighty power; but according to the theory of evolution, it appears that the difference between living creatures arose by chance, and on account of varying conditions of heredity and surroundings, through an endless period of time. The theory of evolution, to speak in simple language, merely asserts, that by chance, in an incalculably long period of time, out of any thing you like, any thing else that you like may develop. This is no answer to the problem. And the same problem is differently expressed: instead of will, chance is offered, and the co-efficient of the eternal is transposed from the power to the time. But this fresh assertion strengthened Comte's assertion. And, moreover, according to the ingenuous confession of the founder of Darwin's theory himself, his idea was aroused in him by the law of Malthus; and he therefore propounded the theory of the struggle of living creatures and people for existence, as the fundamental law of every living thing. And lo! only this was needed by the throng of idle people for their justification. Two insecure theories, incapable of sustaining themselves on their feet, upheld each other, and acquired the semblance of stability. Both theories bore with them that idea which is precious to the crowd, that in the existent evil of human societies, men are not to blame, and that the existing order of things is that which should prevail; and the new theory was adopted by the throng with entire faith and unheard-of enthusiasm. And behold, on the strength of these two arbitrary and erroneous hypotheses, accepted as dogmas of belief, the new scientific doctrine was ratified. Spencer, for example, in one of his first works, expresses this doctrine thus:-- "Societies and organisms," he says, "are alike in the following points:-- "1. In that, beginning as tiny aggregates, they imperceptibly grow in mass, so that some of them attain to the size of ten thousand times their original bulk. "2. In that while they were, in the beginning, of such simple structure, that they can be regarded as destitute of all structure, they acquire during the period of their growth a constantly increasing complication of structure. "3. In that although in their early, undeveloped period, there exists between them hardly any interdependence of parts, their parts gradually acquire an interdependence, which eventually becomes so strong, that the life and activity of each part becomes possible only on condition of the life and activity of the remaining parts.
