FORE: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.

FORE:Tuesday night, August 18th, at about 11 o'clock, a train of luggage carts passed through Canne, and in the village the Browning of one of the soldiers in the last van went off suddenly. This was the100 signal for all Germans to start shooting indiscriminately, anywhere, at anything, happily without hitting anybody. A few tipsy soldiers went to the burgomaster's house, and no sooner had his wife opened the door for the barbarians, when a shot was fired, the bullet passing through the unfortunate lady's head into the wall opposite the door. I was there early the next morning and saw the hole. It is evident that the soldiers ill-treated the dead lady with their rifles in a horrible manner, for a large part of the wall was spattered over with blood."A question that can never be solved," the Countess gasped.

FORE:The scepticism of Protagoras went beyond theology and extended to all science whatever. Such, at least, seems to have been the force of his celebrated declaration that man is the measure of all things, both as regards their existence and their non-existence.67 According to Plato, this doctrine followed from the identification of knowledge with sensible perception, which in its turn was based on a modified form of the Heracleitean theory of a perpetual flux. The series of external changes which constitutes Nature, acting on the series of internal changes which constitutes each mans personality, produces particular sensations, and these alone are the true reality. They vary with every variation in the88 factors, and therefore are not the same for separate individuals. Each mans perceptions are true for himself, but for himself alone. Plato easily shows that such a theory of truth is at variance with ordinary opinion, and that if all opinions are true, it must necessarily stand self-condemned. We may also observe that if nothing can be known but sensation, nothing can be known of its conditions. It would, however, be unfair to convict Protagoras of talking nonsense on the unsupported authority of the Theaettus. Plato himself suggests that a better case might have been made out for the incriminated doctrine could its author have been heard in self-defence. We may conjecture that Protagoras did not distinguish very accurately between existence, knowledge, and applicability to practice. If we assume, what there seems good reason to believe, that in the great controversy of Nature versus Law, Protagoras sided with the latter, his position will at once become clear. When the champions of Nature credited her with a stability and an authority greater than could be claimed for merely human arrangements, it was a judicious step to carry the war into their territory, and ask, on what foundation then does Nature herself stand? Is not she, too, perpetually changing, and do we not become acquainted with her entirely through our own feelings? Ought not those feelings to be taken as the ultimate standard in all questions of right and wrong? Individual opinion is a fact which must be reckoned with, but which can be changed by persuasion, not by appeals to something that we none of us know anything about. Man is the measure of all things, not the will of gods whose very existence is uncertain, nor yet a purely hypothetical state of Nature. Human interests must take precedence of every other consideration. Hector meant nothing else when he preferred the obvious dictates of patriotism to inferences drawn from the flight of birds.

FORE:In the preceding chapter we attempted to show that the tendency of Roman thought, when brought into contact with the Greek systems, was to resolve them into their component elements, or to throw them back on their historical antecedents. As a result of this dissolving process, the Stoicism of the second century split up into a number of more or less conflicting principles, each of which received exclusive prominence according to the changeful mood of the thinker who resorted to philosophy for consolation or for help. Stoicism had originally embraced the dynamism of Heracleitus, the teleology of Socrates, the physical morality of Prodicus and his Cynic successors, the systematising dialectic of Aristotle, the psychism of Plato and the Pythagoreans, and, to a certain extent, the superstitions of popular mythology. With Epicttus, we find the Cynic and the Socratic elements most clearly developed, with Marcus Aurelius, the Socratic and the Heracleitean, the latter being especially strong in the meditations written shortly before his death. In the eastern provinces of the empire, Cynicism was preached as an independent system of morality, and obtained great success by its popular and propagandist character. Dion Chrysostom, a much-admired lecturer of the second century, speaks with enthusiasm of its most famous representative Diogenes, and recounts, with evident gusto, some of the most shameless actions attributed, perhaps falsely, to that eccentric philosopher.383 And the popular rhetorician Maximus Tyrius, although a professed Platonist, places the Cynic life above every other.384 But the traditions of Cynicism were thoroughly opposed to the prevalent polytheism; and its whole attitude was calculated to repel rather than to attract minds penetrated with the enthusiastic spirit of the age. To all such the Neo-Pythagorean doctrine came as a welcome revelation.

FORE:"It is a pity, sir, that you did not arrive a day sooner, then you might have witnessed great barbarity of the Germans. If you walk on a little farther along the canal, you will see three persons hanging from a tree near Haccourt; one of these is a boy of fourteen. Nobody was allowed on the road, and as a patrol met these three persons, they concluded immediately that they were francs-tireurs, strung them up on the tree, without a trial of any sort, and in addition shot each a bullet through the head. To-day another patrol arrived and had the effrontery to tell the members of the Maastricht Red Cross that the boy had murdered a captain. And we are not allowed to remove the corpses. Horrible!... horrible!"
