MENTAL SCIENCE; A COMPENDIUM OF PSYCHOLOGY, AND THE HISTORY OF PHILOSOPHY DESIGNED AS A TEXT-BOOK FOR HIGH-SCHOOLS AND COLLEGES. BY ALEXANDER BAIN, M. A., PROFESSOR OF LOGIC AND MENTAL PHILOSOPHY IN THE UNIVERSITY OF ABERDEEN NEW YORK: CINCINNATI: CHICAGO: ENTERED, according to Act of Congress, in the year 1868, by D. APPLETON & CO., I the Clerk's Office of the District Court of the United States for the Southern Printed by New York, U. S. A. AUTHOR'S PREFACE. THE present treatise contains a Systematic Exposition of MIND, and a History of the leading QUESTIONS in Mental Philosophy. The Exposition of Mind is, for the most part, an abridgment of my two volumes on the subject. I have singled out, and put in conspicuous type, the leading posi tions; and have given a sufficient number of examples to make them understood. It is not to be expected that the full effect of the larger exposition can be produced in the shorter; still, there may be an occasional advantage in the more succinct presentation of complicated doctrines. As regards the controverted QUESTIONS, I have entered fully into the history of opinion, so as to exhibit the dif ferent views, both formerly, and at present, entertained on each. Nominalism and Realism, the Origin of Knowl edge in the mind, External Perception, Beauty, and Free will, are the chief subjects thus treated. ABERDEEN, April, 1868. |
