Our survey of Platos first period is now complete; and we have to enter on the far more arduous task of tracing out the circumstances, impulses, and ideas by which all the scattered materials of Greek life, Greek art, and Greek thought were shaped into a new system and stamped with the impress of an imperishable genius. At the threshold of this second period the personality of Plato himself emerges into greater distinctness, and we have to consider what part it played in an evolution where universal tendencies and individual leanings were inseparably combined.
ONE:Euripides gives us an interesting example of the style in which this ethical application of physical science could be practised. We have seen how Eteocls expresses his determination to do and dare all for the sake of sovereign power. His mother, Jocast, gently rebukes him as follows:
THREE:For Law was feeble, Violence enthroned,Meanwhile the brilliant society season was drawing to a close. Few smart functions remained, but there would be no more dashing affair than the forthcoming ball at Lytton Avenue. The supper was coming from Paris, the decorations were unique, the flowers were to cost upwards of a thousand pounds. The society papers had more or less veracious paragraphs, a score of lady journalists were making copy of the affair.
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.
