‘Are you going home?’ asked the other. ‘My wife, I know, is calling on Lady Keeling, and she will pick me up there. If she has not been so fortunate as to find Lady Keeling in, she will wait for me in the motor. May we not walk down there together?’ ‘My dear,’ he said, ‘I am so glad you have let me come to you. You are in deep waters, poor girl.’ I saw two. "Yes," he said, dismounting and motioning me to do the same. Kendall took our bridles. Leaving him with the animals we went over the fence, through the cotton, across the road at a point terribly near the lighted and guarded shop, and on down the field of corn, to and over its farthest fence; stooping, gliding, halting, crouching, in the cotton-rows and corn-rows; taking every posture two upright gentlemen would rather not take; while nevertheless I swelled with pride, to be alone at the side--or even at the heels--of one who, for all this apparent skulking and grovelling, and in despite of all the hidden drawings of his passion for a fair woman at this hour somewhere in peril, kept his straight course in lion-hearted pursuit of his duty (as he saw it) to a whole world of loves and lovers, martyrs and fighters, hosts of whom had as good a right to their heart's desire as I to mine or he to his; and I remembered Charlotte Oliver saying, on her knees, "I believe no beauty and no joy can be perfect apart from a love that loves the whole world's joy better than any separate joy of any separate soul." That Plato put forward the ethical theory of the Protagoras in perfect good faith cannot, we think, be doubted; although in other writings he has repudiated hedonism with contemptuous aversion; and it seems equally evident that this was his earliest contribution to positive thought. Of all his theories it is the simplest and most Socratic; for Socrates, in endeavouring to reclaim the foolish or vicious, often spoke as if self-interest was the paramount principle of human nature; although, had his assumption been formulated as an abstract proposition, he too might have shrunk from it with something of the uneasiness attributed to Protagoras. And from internal evidence of another description we have reason to think that the Dialogue in question is a comparatively juvenile production, remembering always that the period of youth was much more189 protracted among the Greeks than among ourselves. One almost seems to recognise the hand of a boy just out of college, who delights in drawing caricatures of his teachers; and who, while he looks down on classical scholarship in comparison with more living and practical topics, is not sorry to show that he can discuss a difficult passage from Simonides better than the professors themselves. Nor is this all. After sharply distinguishing what is from what is not, and refusing to admit any intermediary between them, Aristotle proceeds to discover such an intermediary in the shape of what he calls Accidental Predication.236 An accident is an attribute not necessarily or usually inhering in its subject—in other words, a co-existence not dependent on causation. Aristotle could never distinguish between the two notions of cause and kind, nor yet between interferences with the action of some particular cause and exceptions to the law of causation in general; and so he could not frame an intelligible theory of chance. Some propositions, he tells us, are necessarily true, others are only generally true; and it is the exceptions to the latter which constitute accident; as, for instance, when a cold day happens to come in the middle341 of summer. So also a man is necessarily an animal, but only exceptionally white. Such distinctions are not uninteresting, for they prove with what difficulties the idea of invariable sequence had to contend before even the highest intellects could grasp it. There was a constant liability to confound the order of succession with the order of co-existence, the order of our sensations with the order of objective existence, and the subjection of human actions to any fixed order, with the impossibility of deliberation and choice. The earlier Greek thinkers had proclaimed that all things existed by necessity; but with their purely geometrical or historical point of view, they entirely ignored the more complex questions raised by theories about classification, logical attribution, and moral responsibility. And the modifications introduced by Epicurus, into the old physics, show us how unanswerable Aristotle’s reasonings seemed to some of his ablest successors. only three dances with me. He said he was bashful about dancing Please get well--fast--fast--fast. I want to have you close So it was in Larry’s race, with Dick, Sandy and the caretaker. "I'm goin' to stop him killin' mules," he said to himself. "I rayly hope I won't kill him, but that's a secondary matter. Providence'll settle that. It's my duty to stop him. That's clear. If his time's come Providence'll put the bullet where it'll kill him. If it ain't, it won't. That's all. Providence indicates my duty to me. The responsibility for the rest is with Providence, who doeth all things well." ile look 4 it EvEry dAy til i git it. Awake, oh, for shame, ye electors of Rye! He had flung off his coat, and squared up to Realf, who, seeing no alternative, began to strip. "My lord," said Richard, "we are resolved to meet these bold men, and hear what they have to say. Shall you attend us, my lord of Canterbury?" HoME sewangdaquan ENTER NUMBET 00104turks.org.cn
