FORE:Not only oratory and literature, but philosophy and science were cultivated with renewed vigour. The line between philosophy and sophisticism was not, indeed, very distinctly drawn. Epict��tus severely censures the moral teachers of his time for ornamenting their lectures with claptrap rhetoric about the battle of Thermopylae or flowery descriptions of Pan and the Nymphs.406 And the professed declaimers similarly drew on a store of philosophical commonplaces. This sort of popular treatment led to the cultivation of ethics and theology in preference to logic and metaphysics, and to an eclectic blending of the chief systems with one another. A severer method was inculcated in the schools of Athens, especially after the endowment of their professors by Marcus Aurelius; but, in practice, this came to mean what it means in modern universities, the substitution of philology for independent enquiry. The question was not so much what is true as what did Plato or Aristotle really think. Alexandrian science showed something of the same learned and traditional character in the works of Ptolemy; but the great name of Galen marks a real progress in physiology, as well as a return to the principles of Hippocrates.

FORE:In planing and turning, the tools require no exact form; they can be roughly made, except the edge, and even this, in most cases, is shaped by the eye. Such tools are maintained at a trifling expense, and the destruction of an edge is a matter of no consequence. The form, temper, and strength can be continually adapted to the varying conditions of the work and the hardness of material. The line of division between planing and milling is fixed by two circumstances��the hardness and uniformity of the material to be cut, and the importance of duplication. Brass, clean iron, soft steel, or any homogeneous metal not hard enough to cause risk to the tools, can be milled at less expense than planed, provided there is enough work of a uniform character to justify the expense of milling tools. Cutting the teeth of wheels is an example where milling is profitable, but not to the extent generally supposed. In the manufacture of small arms, sewing machines, clocks, and especially watches, where there is a constant and exact duplication of parts, milling is indispensable. Such manufactures are in some cases founded on milling operations, as will be pointed out in another chapter.

FORE:Next to Temperance comes Fortitude; and with it the difficulties of reconciling Epicureanism with the ordinary morality are considerably increased. The old conception of this virtue was willingness to face pain and death on behalf of a noble cause,138 which would be generally understood to mean the salvation of family, friends, and fatherland; and the ultimate sanction of such self-devotion was found in the pressure of public opinion. Idealistic philosophy, taking still higher ground, not69 only refused to balance the fear of pain and death against the fear of infamy or the hope of applause, but added public opinion to the considerations which a good man in the discharge of his duty would, if necessary, despise. Epicurus also inculcated disregard for reputation, except when it might lead to inconveniences of a tangible description;139 but he had nothing beyond the calculations of self-interest to put in its place. A modern utilitarian is bound to undergo loss and suffering in his own person for the prevention of greater loss and suffering elsewhere; an egoistic hedonist cannot consistently be brave, except for the sake of his own future security. The method by which Epicurus reconciled interest with courage was to minimise the importance of whatever injuries could be inflicted by external circumstances; just as in his theory of Temperance he had minimised the importance of bodily pleasures. How he disposed of death will best be seen in connexion with his physical philosophy. Pain he encountered by emphasising, or rather immensely exaggerating, the mind��s power of annulling external sensation by concentrating its whole attention on remembered or anticipated pleasures, or else on the certainty that present suffering must come to an end, and to a more speedy end in proportion to its greater severity. We are to hold a fire in our hand, partly by thinking of the frosty Caucasus, partly by the comforting reflection that the pain of a burn, being intense, will not be of long duration; while, at worst, like the Stoics, we have the resource of suicide as a last refuge from intolerable suffering.140Expedients to avoid dirt in such castings as are to be finished all over or on two sides are various. Careful moulding to avoid loose sand and washing is the first requisite; sinking heads, that rise above the moulds, are commonly employed when castings are of a form which allows the dirt to collect at one point. Moulds for sinking heads are formed by moulders as a rule, but are sometimes provided for by the patterns.

FORE:If Plotinus rose above the vulgar superstitions of the West, while, at the same time, using their language for the easier expression of his philosophical ideas, there was one more refined superstition of mixed Greek and Oriental origin which he denounced with the most uncompromising vigour. This was Gnosticism, as taught by Valentinus and his school. Towards the close of our last chapter, we gave some account of the theory in question. It was principally as enemies of the world and maligners of its perfection that the Gnostics made themselves offensive to the founder of Neo-Platonism. To him, the antithesis of good and evil was represented, not by the opposition of spirit and Nature, but by the opposition between his ideal principle through all degrees of its perfection, and unformed Matter. Like Plato, he looked on the348 existing world as a consummate work of art, an embodiment of the archetypal Ideas, a visible presentation of reason. But in the course of his attack on the Gnostics,518 other points of great interest are raised, showing how profoundly his philosophy differed from theirs, how entirely he takes his stand on the fixed principles of Hellenic thought. Thus he particularly reproaches his opponents for their systematic disparagement of Plato, to whom, after all, they owe whatever is true and valuable in their metaphysics.519 He ridicules their belief in demoniacal possession, with its wholly gratuitous and clumsy employment of supernatural agencies to account for what can be sufficiently explained by the operation of natural causes.520 And, more than anything else, he severely censures their detachment of religion from morality. On this last point, some of his remarks are so striking and pertinent that they deserve to be quoted.250

FORE:But I did not stop long, for after a good look211 round it seemed the best to try and get away as quickly as possible, and in that I succeeded. One understands, however, that it was a terrific disappointment for a man so tired to leave again after thinking that he had at last found a place for rest. At length I found an hotel near the Central Station.
