FORE:In respect to lathe manipulation, which is perhaps the most difficult to learn of all shop operations, the following hints are given, which may prove of service to a learner: At the beginning the form of tools should be carefully studied; this is one of the great points in lathe work; the greatest distinction between a thorough and indifferent latheman is that one knows the proper form and temper of tools and the other does not. The adjustment and presenting of tools is soon learned by experience, but the proper form of tools is a matter of greater difficulty. One of the first things to study is the shape of cutting edges, both as to clearance below the edge of the tool, and the angle of the edge, with reference to both turning and boring, because the latter is different from turning. The angle of lathe tools is clearly suggested by diagrams, and there is no better first lesson in drawing than to construct diagrams of cutting angles for plane and cylindrical surfaces.

FORE:"What on earth are you talking about?" Charlton asked impatiently.It is another Cynic trait in Epicurus that he should67 address himself to a much wider audience than the Sophists, or even than Socrates and his spiritualistic successors. This circumstance suggested a new argument in favour of temperance. His philosophy being intended for the use of all mankind without exception, was bound to show that happiness is within the reach of the poor as well as of the rich; and this could not be did it depend, to any appreciable extent, on indulgences which wealth alone can purchase. And even the rich will not enjoy complete tranquillity unless they are taught that the loss of fortune is not to be feared, since their appetites can be easily satisfied without it. Thus the pains arising from excess, though doubtless not forgotten, seem to have been the least important motive to restraint in his teaching. The precepts of Epicurus are only too faithfully followed in the southern countries for whose benefit they were first framed. It is a matter of common observation, that the extreme frugality of the Italians, by leaving them satisfied with the barest sufficiency, deprives them of a most valuable spur to exertion, and allows a vast fund of possible energy to moulder away in listless apathy, or to consume itself more rapidly in sordid vice. Moreover, as economists have long since pointed out, where the standard of comfort is high, there will be a large available margin to fall back upon in periods of distress; while where it is low, the limit of subsistence will be always dangerously near.

FORE:Meanwhile the scepticism of Protagoras had not been entirely absorbed into the systems of his rivals, but continued to exist as an independent tradition, or in association with a simpler philosophy. The famous school of Megara, about which, unfortunately, we have received very little direct136 information, was nominally a development of the Socratic teaching on its logical side, as the Cynic and Cyrenaic schools were on its ethical side, but like them also, it seems to have a more real connexion with the great impulse previously given to speculation by the Sophists. At any rate, we chiefly hear of the Megarians as having denied the possibility of definition, to which Socrates attached so much importance, and as framing questions not susceptible of a categorical answer,an evident satire on the Socratic method of eliciting the truth by cross-examination.224 What they really derived from Socrates seems to have been his mental concentration and independence of external circumstances. Here they closely resembled the Cynics, as also in their contempt for formal logic; but while Antisthenes found a sanction for his indifference and impassivity in the order of nature, their chief representative, Stilpo, achieved the same result by pushing the sceptical principle to consequences from which even the Cyrenaics would have shrunk. Denying the possibility of attaching a predicate to a subject, he seems, in like manner, to have isolated the mind from what are called its affections, or, at least, to have made this isolation his ideal of the good. Even the Stoics did not go to such a length; and Seneca distinguishes himself from the followers of Stilpo by saying, Our sage feels trouble while he overcomes it, whereas theirs does not feel it at all.225
