PHILOSOPHICAL ESSAYS. WITH MANY NEW AND IMPORTANT ADDITIONS. BY DUGALD STEWART, ESQ. EDITED BY SIR WILLIAM HAMILTON, BART. EDINBURGH: THOMAS CONSTABLE AND CO. HAMILTON, ADAMS, AND CO., LONDON. MDCCCLV. ADVERTISEMENT BY THE EDITOR. THE Philosophical Essays, as an appropriate sequel to the Philosophy of the Human Mind, constitute the Fifth Volume of Mr. Stewart's Collected Works. Of these Essays there have been three editions. The first appeared in 1810, and, as usual, in quarto the others were published in octavo; the second in 1816; the third in 1818. The three are nearly identical in contents; a few trifling additions only (of which the Appendix, p. 455, seq., need alone be noticed) having been made in the later impressions. All the former editions have been employed for the present; the second supplying the printer's copy, whilst the proof was collated with the first and third. As to new matter:-There is a copy of the first or quarto edition, interleaved, containing many additions and corrections by Mr. Stewart; all of which being here incorporated, greatly enhance the value of this edition. The insertions of the Author, now as formerly, are enclosed within square brackets, without any other mark of discrimination. Within what limits I confine my editorial annotations has been stated in previous advertisements. Brief, and merely expository insertions, whether in text or note, though marked. only by the brackets, are the Editor's. Where there appeared any risk of confusion, a formal distinction has usually been made. All the foot-notes, the references of which are not by numerals, proceed from the Editor, even though not expressly marked as new; but the numerals, by which it was intended to discriminate those of Mr. Stewart, have, in a few instances, been inadvertently transferred to notes by his Editor. For the arguments of some of the Parts, Chapters, &c., and for the whole of the running titles, I am responsible. In all of these the change has been determined exclusively by the convenience of the student; who, besides the advantages of an Index, will generally find the numerous quotations verified, corrected, and more articulately referred. I only regret, that this volume having, in great part, been printed during summer, and whilst at a distance from books, I have been prevented in sundry instances from rendering the references more complete.
