ONE:Soon Jeff dropped low, diminished the throb of the engine, cruising while Larry kept watch.
TWO:Amazed, Dick challenged Jeffs statement.It is in this last conversation that the historical Socrates most nearly resembles the Socrates of Platos Apologia. Instead, however, of leaving Euthydmus to the consciousness of his ignorance, as the latter would have done, he proceeds, in Xenophons account, to direct the young mans studies according to the simplest and clearest principles; and we have another conversation where religious truths are instilled by the same catechetical process.92 Here the erotetic method is evidently a mere didactic artifice, and Socrates could easily have written out his lesson under the form of a regular demonstration. But there is little doubt that in other cases he used it as a means for giving increased precision to his own ideas, and also for testing their validity, that, in a word, the habit of oral communication gave him a familiarity with logical processes which could not otherwise have been acquired. The same cross-examination that acted as a spur on the mind of the respondent, reacted as a bridle on the mind of the interrogator, obliging him to make sure beforehand of every assertion that he put forward, to study the mutual bearings of his beliefs, to analyse them into their component elements, and to examine the relation in which they collectively stood to the opinions generally accepted. It has already been stated that Socrates gave the erotetic method two new applications; we now see in what direction they tended. He made it a vehicle for positive instruction, and he also made it an instrument for self-discipline, a help to fulfilling the Delphic precept, Know thyself. The second application was even more important than the first. With us literary trainingthat is, the practice of continuous reading and compositionis so widely diffused, that conversation has become142 rather a hindrance than a help to the cultivation of argumentative ability. The reverse was true when Socrates lived. Long familiarity with debate was unfavourable to the art of writing; and the speeches in Thucydides show how difficult it was still found to present close reasoning under the form of an uninterrupted exposition. The traditions of conversational thrust and parry survived in rhetorical prose; and the crossed swords of tongue-fence were represented by the bristling chevaux de frise of a laboured antithetical arrangement where every clause received new strength and point from contrast with its opposing neighbour.
ONE:So far as he can be said to have studied science at all, the motive of Epicurus was hatred for religion far more than love for natural law. He seems, indeed, to have preserved that aversion for Nature which is so characteristic of the earlier Greek Humanists. He seems to have imagined that by refusing to tie himself down to any one explanation of external phenomena, he could diminish their hold over the mind of man. For when he departs from his usual attitude of suspense and reserve, it is to declare dogmatically that the heavenly bodies are no larger than they appear to our senses, and perhaps smaller than they sometimes appear.170 The only88 arguments adduced on behalf of this outrageous assertion were that if their superficial extension was altered by transmission, their colour would be altered to a still greater degree; and the alleged fact that flames look the same size at all distances.171 It is evident that neither Epicurus nor Lucretius, who, as usual, transcribes him with perfect good faith, could ever have looked at one lamp-flame through another, or they would have seen that the laws of linear perspective are not suspended in the case of self-luminous bodiesa fact which does not tell much for that accurate observation supposed to have been fostered by their philosophy.172 The truth is, that Epicurus disliked the oppressive notion of a sun several times larger than the earth, and was determined not to tolerate it, be the consequences to fact and logic what they might.
TWO:So also with Aristotle. As a naturalist, he is, indeed, purely objective; but when he offers a general explanation of the world, the subjective element introduced by Protagoras and Socrates at once reappears. Simple absolute self-consciousness is for him the highest good, the animating principle of Nature, the most complete reality, and the only one that would remain, were the element of nonentity to disappear from this world. The utter misconception of dynamic phenomena which marks his physics and astronomy can only be accounted for by his desire to give life the priority over mechanical motion, and reason the priority over life. Thus his metaphysical method is essentially identical with the introspective method recommended by Plotinus, and, if fully worked out, might have led to the same results.As a result of the foregoing criticism, Aristotle distinguishes four different causes or principles by which all things are determined to be what they areMatter, Form, Agent, and Purpose.226 If, for example, we take a saw, the matter is steel; the form, a toothed blade; the agent or cause of its assuming that shape, a smith; the purpose, to divide wood or stone. When we have enumerated these four principles, we have told everything that can be known about a saw. But Aristotle could not keep the last three separate; he gradually extended the definition of form until it absorbed, or became identified with, agent and purpose.227 It was what we should call the idea of function that facilitated the transition. If the very essence or nature of a saw implies use, activity, movement, how can we define it without telling its purpose? The toothed blade is only intelligible as a cutting, dividing instrument. Again, how came the saw into being? What shaped the steel into that particular form? We have said that it was the smith. But surely that is too vague. The smith is a man, and may be able to exercise other trades as well. Suppose him to be a musician, did he make the saw in that capacity? No; and here comes in a distinction which plays an immense part in Aristotles metaphysics, whence it has passed into our every-day speech. He does not make the saw qua musician but qua smith. He can, however, in the exercise of his trade as smith make many other toolsknives, axes, and so forth. Nevertheless, had he only learned to make saws it would be enough. Therefore, he does not make335 the saw qua axe-maker, he makes it qua saw-maker. Nor, again, does he make it with his whole mind and body, but only with just those thoughts and movements required to give the steel that particular shape. Now, what are these thoughts but the idea of a saw present in his mind and passing through his eyes and hands, till it fixes itself on the steel? The immaterial form of a saw creates the real saw which we use. Let us apply the preceding analogies to a natural object; for example, a man. What is the Form, the definition of a man? Not a being possessing a certain outward shape, for then a marble statue would be a man, which it is not; nor yet a certain assemblage of organs, for then a corpse would be a man, which, according to Aristotle, criticising Democritus, it is not; but a living, feeling, and reasoning being, the end of whose existence is to fulfil all the functions involved in this definition. So, also, the creative cause of a man is another man, who directly impresses the human form on the material supplied by the female organism. In the same way, every definite individual aggregate becomes what it is through the agency of another individual representing the same type in its perfect manifestation.228
