FORE:On passing to terrestrial physics, we find that Aristotle is, as usual, the dupe of superficial appearances, against which other thinkers were on their guard. Seeing that fire always moved up, he assumed that it did so by virtue of a natural tendency towards the circumference of the universe, as opposed to earth, which always moved towards the centre. The atomists erroneously held that all matter gravitated downwards through infinite space, but correctly explained the ascent of heated particles by the pressure of surrounding matter, in accordance, most probably, with the analogy of floating bodies.200 Chemistry as a science is, of course, an entirely modern creation, but the first approach to it was made by Democritus, while no ancient philosopher stood farther from its essential principles than Aristotle. He analyses bodies, not into their material elements, but into the sensuous qualities, hot and cold, wet and dry, between which he supposes the underlying substance to be perpetually oscillating; a theory which, if it were true, would make any fixed laws of nature impossible.

FORE:Lytton Avenue was quiet for once, and Leona Lalage was glad of it. She said truthfully that she had a splitting headache, so that she was thankful to be alone and lie down on a couch in the drawing-room with the lights lowered and eau de Cologne on her temples. Hetty sat a little way off engaged on some fancywork. It seemed hard to imagine that all this refinement and enviable luxury covered crime and mystery.

FORE:But Epicurus could only borrow the leading principle of his opponents at the expense of an enormous inconsistency. It was long ago pointed out by the Academicians��and the objection has never been answered��that pleasure and mere painlessness cannot both be the highest good, although the one may be an indispensable condition of the other. To confound the means with the end was, indeed, a common fault of Greek philosophy; and the Stoics also were guilty of it when they defined self-preservation to be the natural object of every creature, and yet attached a higher value to the instruments than to the aims of that activity. In Epicureanism, however, the change of front was more open, and was attempted under the eyes of acute and vigilant enemies. If the total absence of pain involves a pleasurable state of consciousness, we have a right to ask for a definition or description of it, and this, so far as can be made out, our philosopher never pretended to supply. Of course, a modern psychologist can point out that the functions of respiration, circulation, secretion, and absorption are constantly going on, and that, in their normal activity, they give rise to a vast sum of pleasurable consciousness, which far more than makes up in volume for what it wants in acuteness. But, whatever his recent interpreters may say,133 Epicurus nowhere alludes to this diffused feeling of vitality; had he recognised it, his enumeration of the positive sensations, apart from which the good is inconceivable, would have seemed as incomplete to him as it does to us. If, on the other hand, the complete removal of pain introduces us to a state of consciousness, which, without being positively pleasurable, has a positive value of some kind, we ought to be told wherein it differs from the ideals of the spiritualist school;66 while, if it has no positive value at all, we ought equally to be told wherein it differs from the unconsciousness of sleep or of death.

FORE:The last alternative seems the most probable. Nature with the Stoics was a fixed objective order whereby all things work together as co-operant parts of a single system. Each has a certain office to perform, and the perfect performance of it is the creature��s virtue, or reason, or highest good: these three expressions being always used as strictly synonymous terms. Here we have the teleology, the dialectics, and the utilitarianism of Socrates, so worked out and assimilated that they differ only as various aspects of a single truth. The three lines of Socratic teaching had also been drawn to a single point by Plato; but his idealism had necessitated the creation of a new world for their development and concentration. The idea of Nature as it had grown up under the hands of Heracleitus, the Sophists, and Antisthenes, supplied Zeno with a ready-made mould into which his reforming aspirations could be run. The true Republic was not a pattern laid up in heaven, nor was it restricted to the narrow dimensions of a single Hellenic state. It was the whole real universe, in every part of which except in the works of wicked men a divine law was recognised and obeyed.46 Nay, according to Cleanthes, God��s law is obeyed even by the wicked, and the essence of morality consists only in its voluntary fulfilment. As others20 very vividly put it, we are like a dog tied under a cart; if we do not choose to run we shall be dragged along.47It was not, however, by its legendary beliefs that the living power of ancient religion was displayed, but by the study and practice of divination. This was to the Greeks and Romans what priestly direction is to a Catholic, or the interpretation of Scripture texts to a Protestant believer. And the Stoics, in their anxiety to uphold religion as a bulwark of morality, went entirely along with the popular superstition; while at the same time they endeavoured to reconcile it with the universality of natural law by the same clumsily rationalistic methods that have found favour with some modern scientific defenders of the miraculous. The signs by which we are enabled to predict an event entered, they said, equally with the event itself, into the order of Nature, being either connected with it by direct causation, as is the configuration of the heavenly bodies at a man��s birth with his after fortunes, or determined from the beginning of the world to precede it according to an invariable rule, as with the indications derived from inspecting the entrails of sacrificial victims. And when sceptics asked of what use was15 the premonitory sign when everything was predestined, they replied that our behaviour in view of the warning was predestined as well.36
