TWO:The three forms of individualism already enumerated do not exhaust the general conception of subjectivity. According to Hegel, if we understand him aright, the most important aspect of the principle in question would be the philosophical side, the return of thought on itself, already latent in physical speculation, proclaimed by the Sophists as an all-dissolving scepticism, and worked up into a theory of life by Socrates. That there was such a movement is, of course, certain; but that it contributed perceptibly to the decay of old Greek morality, or that it was essentially opposed to the old Greek spirit, cannot, we think, be truly asserted. What has been already observed of political liberty and of political unscrupulousness may be repeated of intellectual inquisitiveness, rationalism, scepticism, or by whatever name the tendency in question is to be calledit always was, and still is, essentially characteristic of the Greek race. It may very possibly have been a source of political disintegration at all times, but that it became so to a greater extent after assuming the form of systematic speculation has never been proved. If the study of science, or the passion for intellectual gymnastics, drew men away from the duties of public life, it was simply as one more private interest among many, just like feasting, or lovemaking, or travelling, or poetry, or any other of the occupations in which a wealthy Greek delighted; not from any intrinsic incompatibility with the duties of a statesman or a soldier. So far, indeed, was this from being true, that liberal studies, even of the abstrusest order, were pursued with every advantage to their patriotic energy by such citizens as Zeno, Melissus, Empedocles, and, above all, by Pericles and Epameinondas. If Socrates stood aloof from public business it was that he might have more leisure to train others for its proper performance; and he himself, when called upon to serve the State, proved fully equal to the emergency. As for the Sophists, it is well known that their profession was to give young men the sort of education which would enable251 them to fill the highest political offices with honour and advantage. It is true that such a special preparation would end by throwing increased difficulties in the way of a career which it was originally intended to facilitate, by raising the standard of technical proficiency in statesmanship; and that many possible aspirants would, in consequence, be driven back on less arduous pursuits. But Plato was so far from opposing this specialisation that he wished to carry it much farther, and to make government the exclusive business of a small class who were to be physiologically selected and to receive an education far more elaborate than any that the Sophists could give. If, however, we consider Plato not as the constructor of a new constitution but in relation to the politics of his own time, we must admit that his whole influence was used to set public affairs in a hateful and contemptible light. So far, therefore, as philosophy was represented by him, it must count for a disintegrating force. But in just the same degree we are precluded from assimilating his idea of a State to the old Hellenic model. We must rather say, what he himself would have said, that it never was realised anywhere; although, as we shall presently see, a certain approach to it was made in the Middle Ages.
TWO:In the workshop, mechanical knowledge of some kind is continually and often insensibly acquired by a learner, who observes the operations that are going on around him; he is continually availing himself of the experience of those more advanced, and learns by association the rules and customs of the shop, of the business, and of discipline and management. He gathers the technical terms of the fitting-shop, the forge and foundry; notes the operations of planing, turning, drilling, and boring, with the names and application of the machines directed to these operations. He sees the various plans of lifting and moving material, the arrangement and relation of the several departments to facilitate the course of the work in process; he also learns where the product of the works is sold, discusses the merits and adaptation of what is constructed, which leads to considering the wants that create a demand for this product, and the extent and nature of the market in which it is sold."Ah! That is good hearing. You came here tonight expecting to see Ghetti. But we took the liberty of using Ghetti's name. It is only by the merest accident that I am here tonight to carry out this work. My good friends here would have done it for me otherwise. But I was fortunate enough to escape from the gaol yonder, and here I am."
TWO:An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision.Meanwhile a new and powerful agency was about to interpose with decisive effect in the doubtful struggle. This was the study of mathematics. Revived by the Arabians and never wholly neglected during the Middle Ages, it had profited by the general movement of the Renaissance, and was finally applied to the cosmical problem by Galileo. In this connexion, two points of profound philosophical interest must be noted. The first is that, even in its fall, the Aristotelian influence survived, to some extent, both for good and for evil. To Aristotle belongs the merit of having been the first to base astronomy on physics. He maintains the earths immobility on experimental no less than on speculative grounds. A stone thrown straight up in the air returns to its starting-point instead of falling to the west of it; and the absence of stellar385 parallax seems to show that there is no change in our position relatively to the heavenly bodies. After satisfying himself, on empirical considerations, that the popular astronomy is true, he proceeds to show that it must be true, by considerations on the nature of matter and motion, which, although mistaken, are conceived in a genuinely scientific spirit. Now Galileo saw that, to establish the Copernican system, he must first grapple with the Peripatetic physics, and replace it by a new dynamical theory. This, which he could hardly have effected by the ordinary mathematical methods, he did by borrowing the analytical method of Atomism and applying it to the measurement of motion. The law of falling bodies was ascertained by resolving their descent into a series of moments, and determining its rate of velocity at successive intervals; and curvilinear motions were similarly resolved into the combination of an impulsive with an accelerating force, a method diametrically opposed to that of Bacon, who would not even accept the rough analysis of the apparent celestial motions proposed by Greek astronomers.
