From the Rev. Thomas H. Skinner, D.D., of the Union Theol. Sem., N.Y.
"It is a work of uncommon merit, on a subject very difficult to be treated well. His analysis is complete. He has shunned no question which his purpose required him to answer, and he has met no adversary which he has not overcome."
From Rev. L. P. Hickok, Vice-President of Union College.
"I deem the book well adapted to the ends proposed in the preface. The style is clear, the thoughts perspicuous. I think it calculated to do good, to promote the truth, to diffuse light and impart instruction to the community, in a department of study of the deepest interest to mankind."
From Rev. James Walker, D.D., President of Harvard University.
"Having carefully examined the more critical parts, to which my attention has been especially directed, I am free to express my conviction of the great clearness, discrimination, and accuracy of the work, and of its admirable adaptation to its object."
From Rev. Ray Palmer, D.D., of Albany.
"I have examined this work with great pleasure, and do not hesitate to say that in my judgment it is greatly superior to any treatise I have seen, in all the essential requisites of a good text-book."
From Prof. Rousseau D. Hitchcock, D.D., of Union Theol. Sem., N.Y.
"The task of mediating between science and the popular mind, is one that requires a peculiar gift of perspicuity, both in thought and style; and this, I think, the author possesses in an eminent degree. I am pleased with its comprehensiveness, its plainness, and its fidelity to the Christian stand-point."
From Prof. Henry B. Smith, D.D., of the Union Theol. Sem., N.Y.
"It commends itself by its clear arrangement of the topics, its perspicuity of language, and its constant practical bearings. I am particularly pleased with its views of conscience. Its frequent and pertinent illustrations, and the Scriptural character of its explanations of the particular duties, will make the work both attractive and valuable as a text-book, in imparting instruction upon this vital part of philosophy."
From W. D. Wilson, D.D., Professor of Intellectual and Moral Philosophy in Hobart Free College.
"I have examined the work with care, and have adopted it as a text-book in the study of Moral Science. I consider it not only sound in doctrine, but clear and systematic in method, and withal pervaded with a prevailing healthy tone of sentiment, which cannot fail to leave behind, in addition to the truths it inculcates, an impression in favor of those truths. I esteem this one of the greatest merits of the book. In this respect it has no equal, so far as I know; and I do not hesitate to speak of it as being preferable to any other work yet published, for use in all institutions where Moral Philosophy forms a department in the course of instruction."
