ONE:Returning once more to Epicurus, we have now to sum up the characteristic excellences and defects of his philosophy. The revival of the atomic theory showed unquestionable courage and insight. Outside the school of Democritus, it was, so far as we know, accepted by no other thinker. Plato never mentions it. Aristotle examined and rejected it. The opponents of Epicurus himself treated it as a self-evident absurdity.208 Only Marcus Aurelius seems to have contemplated the possibility of its truth.209. But while to have maintained the right theory in the face of such universal opposition was a proof of no common discernment, we must remember that appropriating the discoveries of others, even when those discoveries are in danger of being lost through neglect, is a very different thing from making discoveries for ones self. No portion of the glory due to Leucippus and Democritus should be diverted to their arrogant successor. And it must also be remembered that the Athenian philosopher, by his theory of deflection, not only spoiled the original hypothesis, but even made it a little ridiculous.It is only in this higher region that perfect virtue can be realised. The maintenance of a settled balance between rival solicitations, or between the excess and defect of those impulses which lead us to seek pleasure and avoid pain, is good indeed, but neither the only nor the chief good. The law of moderation does not extend to that supremely happy life which is related to our emotional existence as the aether to the terrestrial elements, as soul to body, as reason to sense, as science to opinion. Here it is the steady subordination of means to ends which imitates the insphering of the heavenly orbs, the hierarchy of psychic faculties, and the chain of syllogistic arguments. Of theoretic activity we cannot have too much, and all other activities, whether public or private, should be regarded as so much machinery for ensuring its peaceful prosecution. Wisdom and temperance had been absolutely identified by Socrates; they are as absolutely held apart by Aristotle. And what we have had occasion to observe in the other departments of thought is verified here once more. The method of analysis and opposition, apparently so prudent, proved, in the end, unfruitful. Notwithstanding his paradoxes, Socrates was substantially right. The moral regeneration of the world was destined to be brought about, not by Dorian discipline, but by free Athenian thought, working on practical conceptionsby the discovery of new moral truth, or rather by the dialectic development of old truth. And, conversely, the highest development of theoretic activity was not attained by isolating it in egoistic self-contemplation from the world of human needs, but by consecrating it to their service, informing it with their vitality, and subjecting it, in common with them, to that law of moderation from which no energy, however godlike, is exempt.
TWO:In order to render what is said of shop processes more easily understood, it will be necessary to change the order in which they have been named. Designing, and many matters connected with the operation of machines, will be more easily learned and understood after having gone through with what may be called the constructive operations, such as involve manual skill."The Reverend Head has been notified already ten times that he would be shot, and he is frequently being arrested for alleged shooting from the building. This shooting is actually done by German soldiers alone, who are loafing and looting, as I myself noticed a short time ago. The Head took me to a room where an old man of ninety, who had just received the extreme unction, lay dying. By his side sat a broken-hearted little old woman, his wife. This old man had been taken prisoner with other men of Vis, and forced to work at a new bridge. The poor fellow broke down under the strain; it cost him his life."
THREE:Engines operated by means of hot air, called caloric engines, and engines operated by gas, or explosive substances, all act substantially upon the same general principles as steam-engines; the greatest distinction being between those engines wherein the generation of heat is by the combustion of fuel, and those wherein heat and expansion are produced by chemical action. With the exception of a limited number of caloric or air engines, steam machinery comprises nearly all expansive engines that are employed at this day for motive-power; and it may be safely assumed that a person who has mastered the general principles of steam-engines will find no trouble in analysing and understanding any machinery acting from expansion due to heat, whether air, gas, or explosive agents be employed.
