Entered according to Act of Congress, in the year 1854, by PHILIPS, SAMPSON & Co. in the Clerk's Office of the District Court for the District of Massachusetts UNIVERSITY PREFACE. THE following pages contain the substance of the Lectures which, for several years, have been delivered to the classes in Intellectual Philosophy, in Brown University. Having been intended for oral delivery, they were, in many respects, modified by the circumstances of their origin. Hence, illustrations have been introduced more freely than would otherwise have seemed necessary. In preparing them for the press, however, I was led to consider the class of persons for whose use they were principally designed. I remembered the difficulty of fixing definitely in the mind of the pupil the nature and limits of subjective truth; and therefore allowed my instructions to retain in general the form which they had previously assumed. Whether I have in this respect judged wisely, it is not for me to determine. I have not entered upon the discussion of many of the topics which have called into exercise the acumen of the ablest metaphysicians. Intended to serve the purposes of a text-book, it was necessary that the volume should be compressed within a compass adapted to the time usually allotted to the study of this science in the colleges of our country. I have, therefore, attempted to present and illustrate the important truths in intellectual philosophy, rather than the inferences which may be drawn from them, or the doctrines which they may presuppose, These may be pursued to any length, at the option of the teacher. If I have not entered upon these discussions, I hope that I have prepared the way for their more ample and truthful develop ment. |
