The law of organic development announced in the early part of the present century, by Goethe, Schelling, and Von Baer, and vaguely expressed in the formula, that "evolution is always from the homogenous to the heterogeneous, and from the simple to the complex," has recently been extended by Herbert Spencer so as to include all phenomena whatsoever. He has shown that this law of evolution is the law of all evolution. Whether it be in the development of the earth or of life upon its surface, in the development of Society, of government, of manufactures, of commerce, of language, literature, science and art, this same advance from the simple to the complex, through successive differentiations, holds uniformly. The stupendous induction from all classes of phenomena by which Mr. Spencer proceeds to establish and illustrate his theorem cannot be given here.

      Mr. Spencer claims for his view that it is not only a religious position, but preëminently the religious position; and we are most thoroughly disposed to agree with him, though we think he does not appreciate the force of his own argument, nor fully understand his own words. For let us now attempt to realize the meaning of this fact, of which Mr. Spencer and his compeers have put us in possession; let us endeavour to see whether its bearings are really favorable or adverse to religion. They are put forward indeed avowedly as adverse to any other religion than a mere reverential acquiescence in ignorance concerning all that truly exists; but it appears to us that this supposed opposition to religion arises from the fact that the doctrine itself is so profoundly, so intensely, so overwhelmingly religious, nay, so utterly and entirely Christian, that its true meaning could not be seen for very glory. Like Moses, when he came down from the Mount, this positive philosophy comes with a veil over its face, that its too divine radiance may be hidden for a time. This is Science that has been conversing with God, and brings in her hand His law written on tables of stone.

      To answer the question of the likelihood of the permanence of Mr. Mill's philosophic reign, … we should have to take account, among other things, of the differences from Mr. Mill already shown by the extraordinarily able and peculiarly original thinker whose name we have associated with Mr. Mill's at the head of this article. We may take occasion, at another time, to call attention to these speculations of Mr. Herbert Spencer, whose works in the meantime, and especially that new one whose title we have cited, we recommend to all those select readers whose appreciation of masterly exposition, and great reach and boldness of generalization, does not depend on their mere disposition to agree with the doctrines propounded.

      Complete in itself, it is at the same time but a part of a whole, which, if it should be constructed in proportion, will be ten times as great. For these First Principles are merely the foundation of a system of philosophy, bolder, more elaborate and comprehensive, perhaps, than any other which has been hitherto designed in England… Widely as it will be seen we differ from the author on some points, we very sincerely hope he may succeed in accomplishing the bold and magnificent project he has mapped out.

      Our "Survey," superficial as it is, must include at least the mention of a work so lofty in aim, and so remarkable in execution as the system of Philosophy which Mr. Herbert Spencer is issuing to subscribers… In spite of all dissidence respecting the conclusions, the serious reader will applaud the profound earnestness and thoroughness with which these conclusions are advocated; the universal scientific knowledge brought to bear on them by way of illustration, and the acute and subtle thinking displayed in every chapter.

      By these books he has wedged his way into fame in a manner distinctly original, and curiously marked… There is a peculiar charm in this author's style, in that it sacrifices to no common taste, while at the same time it makes the most abstruse questions intelligible… The book, if it is to be noticed with the slightest degree of fairness, requires to be read and re-read, to be studied apart from itself and with itself. For whatever may be its ultimate fate – although as the ages go on it shall become but as the lispings of a little child, a little more educated than other lisping children of the same time – this is certain, that, as a book addressed to the present, it lifts the mind far above the ordinary range of thought, suggests new associations, arranges chaotic pictures, strikes often a broad harmony, and even moves the heart by an intellectual struggle as passionless as fate, but as irresistible as time.

      Mr. Spencer is the foremost mind of the only philosophical school in England which has arrived at a consistent scheme… Beyond this school we encounter an indolent chaotic eclecticism. Mr. Spencer claims the respect due to distinct and daring individuality; others are echoes or slaves. Mr. Spencer may be a usurper, but he has the voice and gesture of a king.

      Mr. Spencer is equally remarkable for his search after first principles; for his acute attempts to decompose mental phenomena into their primary elements; and for his broad generalizations of mental activity, viewed in connection with nature, instinct, and all the analogies presented by life in its universal aspects.
