276. To meet the conditions of rotation in the wheel, and to facilitate the escape of the water without dragging, after it has expended its force upon the vanes, the reversed curves of the turbine is the best-known arrangement.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 Providencea faith in which they closely followed Socrateswould 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.27Besides transforming art and literature, the dialectic method helped to revolutionise social life, and the impulse communicated in this direction is still very far from being exhausted. We allude to its influence on female education. The intellectual blossoming of Athens was aided, in its first development, by a complete separation of the sexes. There were very few of his friends to whom an Athenian gentleman talked so little as to his wife.104 Colonel Mure aptly compares her position to that of an English housekeeper, with considerably less liberty than is enjoyed by the latter. Yet the union of tender admiration with the need for intelligent sympathy and the desire to awaken interest in noble pursuits existed at Athens in full force, and created a field for its exercise. Wilhelm von Humboldt has observed that at this time chivalrous love was kept alive by customs which, to us, are intensely repellent. That so valuable a sentiment should be preserved and diverted into a more legitimate channel was an object of the highest importance. The naturalistic method of ethics did much, but it could not do all, for more was required than a return to primitive simplicity. Here the method of mind stepped in and supplied the deficiency. Reciprocity was the soul of dialectic as practised by Socrates, and the dialectic of love demands a reciprocity of passion which can only exist between the sexes. But in a society where the free intercourse of modern Europe was not permitted, the modern sentiment could not be reached at a single bound; and those who sought for the conversation of intelligent women had to seek for it among a class of which Aspasia was the highest representative. Such women played a great part in later Athenian society; they attended philosophical lectures, furnished heroines to the New Comedy, and on the whole gave a healthier tone to literature. Their successors, the Delias and Cynthias of159 Roman elegiac poetry, called forth strains of exalted affection which need nothing but a worthier object to place them on a level with the noblest expressions of tenderness that have since been heard. Here at least, to understand is to forgive; and we shall be less scandalised than certain critics,105 we shall even refuse to admit that Socrates fell below the dignity of a moralist, when we hear that he once visited a celebrated beauty of this class, Theodot by name;106 that he engaged her in a playful conversation; and that he taught her to put more mind into her profession; to attract by something deeper than personal charms; to show at least an appearance of interest in the welfare of her lovers; and to stimulate their ardour by a studied reserve, granting no favour that had not been repeatedly and passionately sought after.Smoke!

The importance given to religious and moral training; the predominance of the priesthood; the sharp distinction drawn between the military caste and the industrial population; the exclusion of the latter from political power; the partial abolition of marriage and property; and, it might be added, the high position enjoyed by women as regents, chatelaines, abbesses, and sometimes even as warriors or professors,are all innovations more in the spirit of Plato than in the spirit of Pericles. Three converging influences united to bring about this extraordinary verification of a philosophical deal. The profound spiritual revolution effected by Greek thought was taken up and continued by Catholicism, and unconsciously guided to the same practical conclusions the teaching which it had in great part originally inspired. Social differentiation went on at the same time, and led to the political consequences logically deduced from it by Plato. And the barbarian conquest of Rome brought in its train some of those more primitive habits on which his breach with civilisation had equally thrown him back. Thus the coincidence between Platos Republic and mediaeval polity is due in one direction to causal agency, in another to speculative insight, and in a third to parallelism of effects, independent of each other but arising out of analogous conditions.
