Entered, according to Act of Congress, in the year 1861, oy J. T. CHAMPLIN, In the Clerk's Office of the District Court of the District of Maine. 15429 IBM 1.035 PREFACE. THE favor with which my text-book on Intellectual Philosophy has been received, and the need which I have felt in my own classes of a similar book on Ethics, have induced me to add this to the many excellent treatises on that subject already in existence. The great enlargement of the list of studies in our schools and colleges, of late years, renders it more desirable than ever that text-books should be brief, presenting only essential principles, to the neglect of details, which may be supplied by the teacher, or by general reading. These considerations have determined the form of the present treatise. |
