FORE:Probably few contributed so much to the change as Socrates, notwithstanding his general piety and the credulity which he exhibited on this particular point. For his ethical and dialectical training, combined with that careful study of facts which he so earnestly recommended, went very far towards making a consultation of the oracle superfluous; and he did actually impress on his auditors the duty of dispensing with its assistance in all cases except those where a knowledge of the future was necessary and could not be otherwise obtained.340 Even so superstitious a believer as Xenophon improved on his masters lessons in this respect, and instead of asking the Pythia whether he should take service with the younger Cyrusas Socrates had advisedsimply asked to what god he should sacrifice before starting on the expedition. Towards the beginning of our era, as is well known, the Greek oracles had fallen into complete neglect and silence.On the other hand, a theory of reasoning based on the relations of concepts, instead of on the relations of judgments, necessarily leaves out of account the whole doctrine of hypothetical and disjunctive propositions, together with that of the syllogisms based on them; since the elements of which they are composed are themselves propositions. And this inevitable omission is the more remarkable because alterna381tive and, to a less extent, hypothetical arguments form the staple of Aristotles own dialectic; while categorical reasoning never occurs in it at all. His constant method is to enumerate all possible views of a subject, and examine them one after the other, rejecting those which are untenable, and resting content with the remainder. In other words, he reaches his positive conclusions through a series of negative premises representing a process of gradual elimination. The First Analytics is itself an admirable instance of his favourite method. Every possible combination of terms is discussed, and the valid moods are sifted out from a much greater number of illegitimate syllogisms. The dialectic of Socrates and Plato followed the same procedure. It was essentially experimentala method of trial, elimination, and selection. On going back still further, we find that when there is any reasoning at all in Homer, it is conducted after the same fashion. Hector, in his soliloquy before the Scaean Gate, imagines three alternative courses, together exhausting the possibilities of the situation. He may either retreat within the walls, or offer terms of peace to Achilles, or fight. The first two alternatives being rejected, nothing remains but the third. This is the most elaborate example; but on many other occasions Homers actors are represented as hesitating between two courses, and finally deciding on one of them.

FORE:The mechanical engineer deals mainly with the natural forces, and their application to the conversion of material and transport. His calling involves arduous duties; he is brought in contact with what is rough and repulsive, as well as what is scientific and refined. He must include grease, dirt, manual labour, undesirable associations, and danger with apprenticeship, or else be content to remain without thoroughly understanding his profession.
