ONE:It will now be better understood whence arose the hostility of the Stoics to pleasure, and how they could speak of it in what seems such a paradoxical style. It was subjective feeling as opposed to objective law; it was relative, particular, and individual, as opposed to their formal standard of right; and it was continually drawing men away from their true nature by acting as a temptation to vice. Thus, probably for the last reason, Cleanthes could speak of pleasure as contrary to Nature; while less rigorous authorities regarded it as absolutely indifferent, being a consequence of natural actions, not an essential element in their performance. And when their opponents pointed to the universal desire for pleasure as a proof that it was the natural end of animated beings, the Stoics answered that what Nature had in view was not pleasure at all, but the preservation of life itself.48

THREE:Upon entering the shop, a learner will generally, to use a shop phrase, "be introduced to a hammer and chisel;" he will, perhaps, regard these hand tools with a kind of contempt. Seeing other operations carried on by power, and the machines in charge of skilled men, he is likely to esteem chipping and filing as of but little importance and mainly intended for keeping apprentices employed. But long after, when a score of years has been added to his experience, the hammer, chisel, and file, will remain the most crucial test of his hand skill, and after learning to manipulate power tools of all kinds in the most thorough manner, a few blows with a chipping hammer, or a half-dozen strokes with a file, will not only be a more difficult test of skill, but one most likely to be met with.Tempering, as a term, is used to comprehend both hardening and drawing; as a process it depends mainly upon judgment instead of skill, and has no such connection with forging as to be performed by smiths only. Tempering requires a different fire from those employed in forging, and also more care and precision than blacksmiths can exercise, unless there are furnaces and baths especially arranged for tempering tools.
THREE:The principal improvements and changes in machine fitting at the present time is in the application of special tools. A lathe, a planing machine, or drilling machine as a standard machine, must be adapted to a certain range of work, but it is evident that if such tools were specially arranged for either the largest or the smallest pieces that come within their capacity, more work could be performed in a given time and consequently at less expense. It is also evident that machine tools must be kept constantly at work in order to be profitable, and when there are not sufficient pieces of one kind to occupy a machine, it must be employed on various kinds of work; but whenever there are sufficient pieces of the same size upon which certain processes of a uniform character are to be performed, there is a gain by having machines constructed to conform as nearly as possible to the requirements of special work, and without reference to any other.Larry, clinging to a brace, his feet set on a strut, bent closer.
