Considered as a mechanical agent, a hammer concentrates the power of the arms, and applies it in a manner that meets the requirements of various purposes. If great force is required, a long swing and slow blows accomplish tons; if but little force is required, a short swing and rapid blows will servethe degree of force being not only continually at control, but also the direction in which it is applied. Other mechanism, if employed instead of hammers to perform a similar purpose, would require to be complicated [104] machines, and act in but one direction or in one plane.
Yet, while the Stoics were far from anticipating the methods of modern Utilitarianism, they were, in a certain sense, strict Utilitariansthat is to say, they measured the goodness or badness of actions by their consequences; in other words, by39 their bearing on the supposed interest of the individual or of the community. They did not, it is true, identify interest with pleasure or the absence of pain; but although, in our time, Hedonism and Utilitarianism are, for convenience, treated as interchangeable terms, they need not necessarily be so. If any one choose to regard bodily strength, health, wealth, beauty, intellect, knowledge, or even simple existence, as the highest good and the end conduciveness to which determines the morality of actions, he is a Utilitarian; and, even if it could be shown that a maximum of happiness would be ensured by the attainment of his end, he would not on that account become a Hedonist. Now it is certain that the early Stoics, at least, regarded the preservation of the human race as an end which rightfully took precedence of every other consideration; and, like Charles Austin, they sometimes pushed their principles to paradoxical or offensive extremes, apparently for no other purpose than that of affronting the common feelings of mankind,84 without remembering that such feelings were likely to represent embodied experiences of utility. Thusapart from their communistic theoriesthey were fond of specifying the circumstances in which incest would become legitimate; and they are said not only to have sanctioned cannibalism in cases of extreme necessity, but even to have recommended its introduction as a substitute for burial or cremation; although this, we may hope, was rather a grim illustration of what they meant by moral indifference than a serious practical suggestion.85
ONE:1. The most economical and effectual mechanism for handling is that which places the amount of force and rate of movement continually under the control of an operator.What was wrong?
Considering material progress as consisting primarily in the demonstration of scientific truths, and secondly, in their application to useful purposes, we can see the position of the engineer as an agent in this great work of reconstruction now going on around us. The position is a proud one, but not to be attained except at the expense of great effort, and a denial of everything that may interfere with the acquirement of knowledge during apprenticeship and the study which must follow.The Epicurean philosophy of external Nature was used as an instrument for destroying the uncomfortable belief in Divine Providence. The Epicurean philosophy of mind was used to destroy the still more uncomfortable belief in mans immortality. As opinions then stood, the task was a comparatively easy one. In our discussion of Stoicism, we observed that the spiritualism of Plato and Aristotle was far before their age, and was not accepted or even understood by their countrymen for a long time to come. Moreover, Aristotle did not agree with his master in thinking that the personal eternity of the soul followed from its immateriality. The belief of the Stoics in a prolongation of individual existence until the destruction of all created things by fire, was, even in that very limited form, inconsistent with their avowed materialism, and had absolutely no influence on their practical89 convictions. Thus Platos arguments were alone worth considering. For Epicurus, the whole question was virtually settled by the principle, which he held in common with the Stoics, that nothing exists but matter, its attributes, and its relations. He accepted, it is true, the duality of soul and body, agreeing, in this respect also, with the Stoics and the earlier physicists; and the familiar antithesis of flesh and spirit is a survival of his favourite phraseology;173 but this very term flesh was employed to cover the assumption that the body to which he applied it differed not in substance but in composition from its animating principle. The latter, a rather complex aggregate, consists proximately of four distinct elements, imagined, apparently, for the purpose of explaining its various functions, and, in the last analysis, of very fine and mobile atoms.174 When so much had been granted, it naturally followed that the soul was only held together by the body, and was immediately dissolved on being separated from ita conclusion still further strengthened by the manifest dependence of psychic on corporeal activities throughout the period of their joint existence. Thus all terrors arising from the apprehension of future torments were summarily dispelled.Thus it went on all day long: motors and other conveyances travelled to and fro between the battle-17fields and hospitals at Maastricht; fugitives moved about in streets and squares, upsetting each other more and more by fantastic stories.
