Within the last twelve years several books, both large and small, have appeared, dealing¹ either with the philosophy of Aristotle as a whole, or with the general principles on which it is constructed. The Berlin edition of Aristotle’s collected works was supplemented in 1870 by the publication of a magnificent index, filling nearly nine hundred quarto pages, for which we have to thank the learning and industry of Bonitz.161 Then came the unfinished treatise² of George Grote, planned on so vast a scale that it would, if completely carried out, have rivalled the author’s History of Greece in bulk, and perhaps exceeded the authentic³ remains⁴ of the Stagirite himself. As it is, we have a full account, expository and critical, of the Organon, a chapter on the De Anima, and some fragments on other Aristotelian writings, all marked by Grote’s wonderful sagacity and good sense. In 1879 a new and greatly enlarged edition brought that portion of Zeller’s work on Greek Philosophy which deals with Aristotle and the Peripatetics162 fully⁶ up to the level of its companion volumes; and we are glad to see that, like them, it is shortly to appear in an English dress. The older work of Brandis163 goes over the same ground, and, though much behind the present state of knowledge, may still be consulted with advantage, on account of its copious⁷ and clear analyses of the Aristotelian texts.276 Together with these ponderous⁸ tomes, we have to mention the little work of Sir Alexander Grant,164 which, although intended primarily for the unlearned, is a real contribution to Aristotelian scholarship, and, probably as such, received the honours of a German translation almost immediately after its first publication. Mr. Edwin Wallace’s Outlines of the Philosophy of Aristotle165 is of a different and much less popular character. Originally designed for the use of the author’s own pupils, it does for Aristotle’s entire system what Trendelenburg has done for his
