OF THE PHILOSOPHY OF THE HUMAN MIND. VOL. I. TO WHICH IS PREFIXED, INTRODUCTION AND PART FIRST OF THE OUTLINES OF MORAL PHILOSOPHY. WITH MANY NEW AND IMPORTANT ADDITIONS. BY DUGALD STEWART, ESQ. EDITED BY SIR WILLIAM HAMILTON, BART. EDINBURGH: THOMAS CONSTABLE AND CO. LITTLE, BROWN, AND CO., BOSTON, U.S. MDCCCLIV. 120665 JUL T 1908 BE ·ST4 रान ADVERTISEMENT BY THE EDITOR. THE second, third, and fourth volumes of Stewart's Collected Works comprise the three volumes of his Elements of the Philosophy of the Human Mind, to which, as a summary, is prefixed the "Introduction" and "Part First, (Of the Intellectual Powers,)" from his Outlines of Moral Philosophy. These are the only writings in which the Author has systematically considered, (though, like his predecessors, not perhaps under the most appropriate titles,) the cognitive faculties of mind;-faculties which stand distinctively apart, and prominently foremost. For, if we take the Mental to the exclusion of Material phænomena, that is, the phænomena manifested through the medium of Self-consciousness or Reflection, they naturally divide themselves into three categories or primary genera;-the phænomena of Knowledge or Cognition,-the phænomena of Feeling or of Pleasure and Pain, and the phænomena of Conation or of Will and Desire. Now, of these classes, the two treatises which constitute the present section of the Works, are conversant exclusively with the first,-the phænomena of Cognition; the other classes, the Feelings and the Conations, are treated, as we shall see, in subsequent books. But to speak particularly of the treatises, one of which is here partially combined with the other. The Outlines of Moral Philosophy were first published in 1793. A second edition, "enlarged," followed in 1801; and a third, "corrected," in 1808. One other edition, in 1818, appeared during the lifetime of the author, but without alteration; and since his death the work has been frequently reprinted. Of the first three editions, there are copies extant with the author's manuscript annotations; which, with a few unimportant exceptions, are all incorporated in the present collection; and distinguished as found in the first, in the second, or in the third edition. As to the Elements of the Philosophy of the Human Mind, the Three Volumes, of which the complete work consists, appeared at considerable intervals; and of each, the original edition was in quarto, the others being in octavo.-The First Volume (the earliest of Mr. Stewart's writings) was published so long ago as 1792; a few trifling additions were made in the second edition, 1802; but though often subsequently reprinted, no alteration or amplification,-none certainly of any consequence, has been hitherto incorporated. In the third volume, 1827, a considerable number of intended additions were indeed supplied; but these have only now been entered in their proper places. The Second Volume was first published in 1814, and three subsequent editions (in 1816, 1821, and 1822) appeared during the lifetime of the author,-but without change.-The Third Volume dates from 1827; and of this there has been no second edition. It may be noticed, that the Outlines of Moral Philosophy were, in 1846, translated into French, and published in Paris by the celebrated M. Jouffroi; whilst, in 1808, a not less illustrious philosopher, a personal friend too of Mr. Stewart, M. Prévost of Geneva, had done the same by the first volume of the Elements.
