STEREOTYPED AT THE BOSTON STEREOTYPE FOUNDRY PREFACE TO THE SECOND EDITION. THE favor with which the first edition of this work has been received, has conspired, with a desire to give it an extensive and enduring circulation as a text book, to induce the author carefully' to revise and to stereotype it for a second and enlarged edition. Great pains have been taken to render the statements and discussions as thorough, luminous, and condensed as the nature of the work admits. Technical terms are mostly avoided; quotations from foreign languages are introduced only in English; and every sentence in the book is studiously brought within the apprehension of all who are accustomed to reflect. Having devoted several years to teaching, the author has realized the difficulty of interesting the minds of the young, and of conducting them to sound and discriminating views on subjects of this nature. This difficulty it has been his special effort to remove; and he has been induced to believe, both from his own experience and the assurance of distinguished teachers, that the effort has not been in vain. The author is now preparing a work on MORAL PHILOSOPHY, similar in size and plan to this, and intended to succeed it in a course of study, which may be expected within a few months. In the mean time, he respectfully dedicates this volume to his fellowteachers and their pupils, for whom it is especially designed, with the earnest desire that those who use it as a text book may realize as much satisfaction and profit in the study of it as he has in its preparation.
