THREE:As to the shades that appear in drawing temper, or tempering it is sometimes called, it is quite useless to repeat any of the old rules about "straw colour, violet, orange, blue," and so on; the learner knows as much after such instruction as before. The shades of temper must be seen to be learned, and as no one is likely to have use for such knowledge before having opportunities to see tempering performed, the following plan is suggested for learning the different shades. Procure eight pieces of cast steel about two inches long by one inch wide and three-eighths of an inch thick, heat them to a high red heat and drop them into a salt bath; preserve one without tempering to show the white shade of extreme hardness, and polish one side of each of the remaining seven pieces; then give them to an experienced workman to be drawn to seven varying shades of temper ranging from the white piece to the dark blue colour of soft steel. On the backs of these pieces labels can be pasted describing the technical names of the shades and the general uses to which tools of corresponding hardness are adapted.Of all testimonies to the restored supremacy of Aristotelianism, there is none so remarkable as that afforded by the thinker who, more than any other, has enjoyed the credit of its overthrow. To call Francis Bacon an Aristotelian will seem to most readers a paradox. Such an appellation would, however, be much nearer the truth than were the titles formerly bestowed on the author of the Novum Organum. The notion, indeed, that he was in any sense the father of modern science is rapidly disappearing from the creed of educated persons. Its long continuance was due to a coalition of literary men who knew nothing about physics and of physicists who knew nothing about philosophy or its history. It is certain that the great discoveries made both before and during Bacons lifetime were the starting-point of all future progress in the same direction. It is equally certain that Bacon himself had either not heard of those discoveries or that he persistently rejected them. But it might still be contended that he divined and formulated the only method by which these and all other great additions to human knowledge have been made, had not the delusion been dispelled by recent investigations, more especially those of his own editors, Messrs. Ellis and Spedding. Mr. Spedding has shown that Bacons method never was applied to physical science at all. Mr. Ellis has shown that it was incapable of application, being founded on a complete misconception of the problem to be solved. The facts could in truth, hardly have been other373 than what they are. Had Bacon succeeded in laying down the lines of future investigation, it would have been a telling argument against his own implied belief that all knowledge is derived from experience. For, granting the validity of that belief, a true theory of discovery can only be reached by an induction from the observed facts of scientific practice, and such facts did not, at that time, exist in sufficient numbers to warrant an induction. It would have been still more extraordinary had he furnished a clue to the labyrinth of Nature without ever having explored its mazes on his own account. Even as it is, from Bacons own point of view the contradiction remains. If ever any system was constructed priori the Instauratio Magna was. But there is really no such thing as priori speculation. Apart from observation, the keenest and boldest intellect can do no more than rearrange the materials supplied by tradition, or give a higher generalisation to the principles of other philosophers. This was precisely what Bacon did. The wealth of aphoristic wisdom and ingenious illustration scattered through his writings belongs entirely to himself; but his dream of using science as an instrument for acquiring unlimited power over Nature is inherited from the astrologers, alchemists, and magicians of the Middle Ages; and his philosophical system, with which alone we are here concerned, is partly a modification, partly an extension, of Aristotles. An examination of its leading features will at once make this clear.

THREE:"Of course, there was no face there," Balmayne flared out. "That's the worst of doing this kind of thing with a woman--one never knows when she's going to have an attack of nerves. The idea of Charlton standing at the window and knowing what we are going to do is too good. Pull yourself together."It will be remembered that in an earlier section of this chapter we accompanied Plato to a period when he had provisionally adopted a theory in which the Protagorean contention that virtue can be taught was confirmed and explained by the Socratic contention that virtue is knowledge; while this knowledge again was interpreted in the sense of a hedonistic calculus, a prevision and comparison of the pleasures and pains consequent on our actions. We have now to trace the lines of thought by which he was guided to a different conception of ethical science.
