Although Dr Reid does not stand in the very highest rank of philosophers, this incomparable edition of his works goes far to redress his deficiencies, and to render his writings, taken in connexion with the editorial commentaries, a most engaging and profitable study. It is probable that the book derives much of its excellence from the very imperfections of the textual author. Had Reid been a more learned man, he might have failed to elicit the unparalleled erudition of his editor,--had he been a clearer and closer thinker, Sir William Hamilton's vigorous logic and speculative acuteness, would probably have found a narrower field for their display. On the whole, we cannot wish that Reid had been either more erudite or more perspicacious, so pointed and felicitous is the style in which his errors are corrected, his thoughts reduced to greater precision, his ambiguities pointed out and cleared up, and his whole system set in its most advantageous light, by his admiring, though by no means idolatrous editor. Besides being a model of editorship, this single volume is, in so far as philosophy and the history of philosophical opinion are concerned, of itself a literature. We must add, however, that Sir William Hamilton's dissertations, though abundant, are not yet completed. Yet, in spite of this drawback, the work is one which ought to wipe away effectually from our country the reproach of imperfect learning and shallow speculation; for in depth of thought, and extent and accuracy of knowledge, the editor's own contributions are of themselves sufficient to bring up our national philosophy (which had fallen somewhat into arrear) to a level with that of the most scientific countries in Europe.
