You can learn nothing from that, Miss Serena spoke up. Too many are away.
There is, perhaps, no more fitting conclusion to these suggestions for apprentices than a word about health and strength. It was remarked in connection with the subject of drawing, that the powers of a mechanical engineer were to be measured by his education and mental abilities, no more than by his vitality and physical strength, a proposition which it will be well for an apprentice to keep in mind.
The following propositions in regard to tempering, comprehend the main points to be observed:
But with his nerves taut, by sheer power of his cool will forcing himself to work steadily but not sharply, he brought the nose up, closing his eyes to that wild nightmare of water seeming to be leaping toward the airplane.
Another difference between solid and expanding dies, which may be pointed out, is in the firmness with which the cutting edges are held. With a solid die, the edges or teeth being all combined in one solid piece, are firmly held in a fixed position; while with expanding dies their position has to be maintained by mechanical devices which are liable to yield under the pressure which arises in cutting. The result is, that the precision with which a screwing machine with movable dies will act, is dependent upon the strength of the 'abutment' behind the dies, which should be a hard unyielding surface with as much area as possible.
He gave them his theory.It was by that somewhat slow and circuitous process, the negation of a negation, that spiritualism was finally established. The shadows of doubt gathered still more thickly around futurity before another attempt could be made to remove them. For the scepticism of the Humanists and the ethical dialectic of Socrates, if they tended to weaken the dogmatic materialism of physical philosophy, were at first238 not more favourable to the new faith which that philosophy had suddenly eclipsed. For the one rejected every kind of supernaturalism; and the other did not attempt to go behind what had been directly revealed by the gods, or was discoverable from an examination of their handiwork. Nevertheless, the new enquiries, with their exclusively subjective direction, paved the way for a return to the religious development previously in progress. By leading men to think of mind as, above all, a principle of knowledge and deliberate action, they altogether freed it from those material associations which brought it under the laws of external Nature, where every finite existence was destined, sooner or later, to be reabsorbed and to disappear. The position was completely reversed when Nature was, as it were, brought up before the bar of Mind to have her constitution determined or her very existence denied by that supreme tribunal. If the subjective idealism of Protagoras and Gorgias made for spiritualism, so also did the teleological religion of Socrates. It was impossible to assert the priority and superiority of mind to matter more strongly than by teaching that a designing intelligence had created the whole visible universe for the exclusive enjoyment of man. The infinite without was in its turn absorbed by the infinite within. Finally, the logical method of Socrates contained in itself the germs of a still subtler spiritualism which Plato now proceeded to work out.
