TWO:Every variety of opinion current among the Sophists reduces itself, in the last analysis, to their fundamental antithesis between Nature and Law, the latter being somewhat ambiguously conceived by its supporters as either human reason or human will, or more generally as both together, combining to assert their self-dependence and emancipation from external authority. This antithesis was prefigured in the distinction between Chthonian and Olympian divinities. Continuing afterwards to inspire the rivalry of opposing schools, Cynic against Cyrenaic, Stoic against Epicurean, Sceptic against Dogmatist, it was but partially overcome by the mediatorial schemes of Socrates and his successors. Then came Catholicism, equally adverse to the pretensions of either party, and held them down101 under its suffocating pressure for more than a thousand years.To return to shop processes in manufacturing. Material operated upon has to be often, sometimes continually, moved from one place to another to receive successive operations, and this movement may be either vertically or horizontally as determined, first, by the relative facility with which the material may be raised vertically, or moved horizontally, and secondly, by [64] the value of the ground and the amount of room that may be available, and thirdly by local conditions of arrangement. In large cities, where a great share of manufacturing is carried on, the value of ground is so great that its cost becomes a valid reason for constructing high buildings of several storeys, and moving material vertically by hoists, thus gaining surface by floors, instead of spreading the work over the ground; nor is there any disadvantage in high buildings for most kinds of manufacture, including machine fitting even, a proposition that will hardly be accepted in Europe, where fitting operations, except for small pieces, are rarely performed on upper floors.
