"Why, young lady, it's hard to doubt anything you say, but really that sounds rather fanciful. Why should you think it?" He made a motion of pain--"Don't say it!" and we read in each other's eyes the one conviction that from a surgeon's personal knowledge this man had written to warn Charlotte that Oliver was alive. "1. That it is prohibited to be out of doors after seven o'clock (Belgian time) in the evening. "Ah well, be you a Fleming?" In returning to one of the older cosmologies, the Stoics placed themselves in opposition to the system of Aristotle as a whole, although on questions of detail they frequently adopted his conclusions. The object of Heracleitus, as against the Pythagoreans, had been to dissolve away every antithesis in a pervading unity of contradictories; and, as against the Eleatics, to substitute an eternal series of transformations for the changeless unity of absolute existence. The Stoics now applied the same method on a scale proportionate to the subsequent development of thought. Aristotle had carefully distinguished God from the world, even to the extent of isolating him from all share in its creation and interest in its affairs. The Stoics declared that God and the world were one. So far, it is allowable to call them pantheists. Yet their pantheism was very different from what we are accustomed to denote by that name; from the system of Spinoza, for example. Their strong faith in final causes and in Providence—a faith in which they closely followed Socrates—would be hardly consistent with anything but the ascription of a distinct and individual consciousness to the Supreme Being, which is just what modern pantheists refuse to admit. Their God was sometimes described as the soul of the world, the fiery element surrounding and penetrating every other kind of matter. What remained was the body of God; but it was a body which he had originally created out of his own substance, and would, in the fulness of time, absorb into that substance again.25 Thus they kept the future conflagration foretold by Heracleitus, but gave it a more religious colouring. The process of creation was then to begin over again, and all things were to run the same12 course as before down to the minutest particulars, human history repeating itself, and the same persons returning to live the same lives once more.26 Such a belief evidently involved the most rigid fatalism: and here again their doctrine offers a pointed contrast to that of Aristotle. The Stagirite, differing, as it would seem, in this respect from all the older physicists, maintained that there was an element of chance and spontaneity in the sublunary sphere; and without going very deeply into the mechanism of motives or the theory of moral responsibility, he had claimed a similar indeterminateness for the human will. Stoicism would hear of neither; with it, as with modern science, the chain of causation is unbroken from first to last, and extends to all phenomena alike. The old theological notion of an omnipotent divine will, or of a destiny superior even to that will, was at once confirmed and continued by the new theory of natural law; just as the predestination of the Reformers reappeared in the metaphysical rationalism of Spinoza.27 417 Jeff got his engine going by setting it on a compression point when he had primed the cylinders and using his booster magneto to furnish the hot sparks that gave it its first impulse. Taking this view of his Continental neighbours, George was driven to the conclusion that his only safety lay in firmly engaging France to relinquish the Pretender. The means of the attainment of this desirable object lay in the peculiar position of the Regent, who was intent on his personal aims. So long as the chances of the Pretender appeared tolerable, the Regent had avoided the overtures on this subject; but the failure of the expedition to the Highlands had inclined him to give up the Pretender, and he now sent the Abbé Dubois to Hanover to treat upon the subject. He was willing also to destroy the works at Mardyk as the price of peace with England. The preliminaries were concluded, and the Dutch included in them; but the Treaty was not ratified till January, 1717. "Jest as I expected, Si," Shorty called back to him. "The rebels have throwed back a squad to watch for us." The crest of Boarzell was just visible against the luminous sky. There was something sinister and challenging about those firs. The gorse round their trunks seemed in that strange half-stormy, half-peaceful night to throw off a faint glimmer of gold. The fiddle wept and sang into the darkness, and outside the window two cherry trees scraped their boughs together. "Well, I d?an't know where he is."
