TWO:"It must be done, surely, it must be done! That is her only chance of escape, and if she stops here she will be killed with the rest of us. Oh!... oh!..."
TWO:Within the last twelve years several books, both large and small, have appeared, dealing either with the philosophy of Aristotle as a whole, or with the general principles on which it is constructed. The Berlin edition of Aristotles 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 treatise of George Grote, planned on so vast a scale that it would, if completely carried out, have rivalled the authors History of Greece in bulk, and perhaps exceeded the authentic remains 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 Grotes wonderful sagacity and good sense. In 1879 a new and greatly enlarged edition brought that portion of Zellers work on Greek Philosophy which deals with Aristotle and the Peripatetics162 fully 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 copious and clear analyses of the Aristotelian texts.276 Together with these ponderous 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 Wallaces Outlines of the Philosophy of Aristotle165 is of a different and much less popular character. Originally designed for the use of the authors own pupils, it does for Aristotles entire system what Trendelenburg has done for his logic, and Ritter and Preller for all Greek philosophythat is to say, it brings together the most important texts, and accompanies them with a remarkably lucid and interesting interpretation. Finally we have M. Barthlemy Saint-Hilaires Introduction to his translation of Aristotles Metaphysics, republished in a pocket volume.166 We can safely recommend it to those who wish to acquire a knowledge of the subject with the least possible expenditure of trouble. The style is delightfully simple, and that the author should write from the standpoint of the French spiritualistic school is not altogether a disadvantage, for that school is partly of Aristotelian origin, and its adherents are, therefore, most likely to reproduce the masters theories with sympathetic appreciation.To make this plainer, the laws of forces, the proportion of parts, strength of material, and so on, are subjects of general knowledge that may be acquired from books, and understood without the aid of an acquaintance with the technical conditions of either the mode of constructing or the manner of operating machines; but how to construct proper patterns for castings, or how the parts of machinery should be moulded, forged, or fitted, is special knowledge, and must have reference to particular cases. The proportions of pulleys, bearings, screws, or other regular details of machinery, may be learned from general rules and principles, but the hand skill that enters into the manufacture of these articles cannot be learned except by observation and experience. The general design, or the disposition of metal in machine-framing, can be to a great extent founded upon rules and constants that have general application; but, as in the case of wheels, the plans of moulding such machine frames are not governed by constant rules or performed in a uniform manner. Patterns of different kinds may be employed; moulds may be made in various ways, and at a greater and less expense; the metal can be mixed to produce a hard or a soft casting, a strong or a weak one; the conditions under which the metal is poured may govern the soundness or shrinkage,things that are determined by special instead of general conditions.
