“Every year seems to widen the influence of that philosophical inquirer, in whom, long ago, J. S. Mill recognized one of the most vigorous as well as boldest thinkers that English speculation has produced. As the majestic outlines of his design have been disclosed, there has been a growing willingness to recognize not only the breadth and solidity of his conclusions, but their regulative bearing on human conduct and the practical concerns of life. It remained for the author to define the final outcome of his philosophy, and this has been done in the present work.”—New York Sun. “Mr. Spencer's main purpose is to ascertain and describe the objective qualities of right conduct, the external signs of the highest virtue, and to show their coincidence with the results of progressive evolution. This he has done in the course of the pro¬ found and exhaustive analysis, of which he is so consummate a master, of vigorous but singularly lucid reasonings, and of ample and impressive illustrations from every department of Nature.”—New York Tribune. “ We think that the verdict on this book of all candid readers will be that it accom¬ plishes what it professses to accomplish—it finds for the principles of right and wrong in conduct a scientific basis ; and, if this be true, it is needless to say that its effect will be to give a new impulse and a new direction to ethical studies."—Popular Science

Monthly. “ However widely many will differ with Air. Spencer as to some of his generaliza¬ tions, and especially as to his great underlying theory, all must admife and value the clearness and fairness of his reasoning, his wonderful master}- of facte in all domains of science, the keenness of his philosophic insight, and the singular beauty of his ethical teachings. His impress upon the speculative thought of the agre is undoubtedly greater than that of any other living man.”—Chicago Evening Journal. “As examples of lucid, elegant style, Air. Spencer’s writings deserve careful study; but beyond and above mere form he is deserving of higher praise. Lucid style ac¬ companies a wonderfully trained brain, filled with almost all kind6 of contemporary knowledge, thoughts that reach, surround, and master the loftiest subjects, a love of symmetry that connects masses of heterogeneous and conflicting thoughts into perfect order and harmony, and an almost miraculous patience that is an attribute of genius alone.”—Boston Gazette. “This book is constructed upon a clear and symmetrical plan, and is a model of lucid and terse treatment. Such are the author's richness and variety of knowledge that he is able to illustrate at every step the abstract principles which he lays down by concrete instances cited from Sociology or the physical sciences. In no chapter doe's his grasp of the subject appear more firm than in that on the ; Evolution of Conduct.’ ” — Baltimore Gazette.
