"The work of Dr. Wayland has arisen gradually from the necessity of correcting the false principles and fallacious reasonings of Paley. It is a radical mistake, in the education of youth, to permit any book to be used by students as a text-book, which contains erroneous doctrines, especially when these are fundamental, and tend to vitiate the whole system of morals. We have been greatly pleased with the method which President Wayland has adopted; he goes back to the simplest and most fundamental principles; and, in the statement of his views, he unites perspicuity with conciseness and precision. In all the author's leading fundamental principles we entirely concur."--_Biblical Repository._ "This is a new work on morals, for academic use, and we welcome it with much satisfaction. It is the result of several years' reflection and experience in teaching, on the part of its justly distinguished author; and if it is not perfectly what we could wish, yet, in the most important respects, it supplies a want which has been extensively felt. It is, we think, substantially sound in its fundamental principles; and being comprehensive and elementary in its plan, and adapted to the purposes of instruction, it will be gladly adopted by those who have for a long time been dissatisfied with the existing works of Paley."--_The Literary and Theological Review._ =MORAL SCIENCE, ABRIDGED,= by the Author, and adapted to the use of Schools and Academies. Twenty-fifth Thousand. 18mo, half cloth. Price 25 cents. The more effectually to meet the desire expressed for a cheap edition, the present edition is issued at the reduced price of 25 cents per copy, and it is hoped thereby to extend the benefit of moral instruction to all the youth of our land. Teachers and all others engaged in the training of youth, are invited to examine this work. "Dr. Wayland has published an abridgment of his work, for the use of schools. Of this step we can hardly speak too highly. It is more than time that the study of moral philosophy should be introduced into all our institutions of education. We are happy to see the way so auspiciously opened for such an introduction. It has been not merely abridged, but also re-written. We cannot but regard the labor as well bestowed."--_North American Review._ "We speak that we do know, when we express our high estimate of Dr. Wayland's ability in teaching Moral Philosophy, whether orally or by the book. Having listened to his instructions, in this interesting department, we can attest how lofty are the principles, how exact and severe the argumentation, how appropriate and strong the illustrations which characterize his system and enforce it on the mind."--_The Christian Witness._
