ONE:I shuddered at the thought that in these days such barbarities were possible. I asked the soldiers whether I was allowed to enter the burning village, but the commanding sergeant refused his consent.The last guest had departed, the strains of music had died away. The lights were out, and the flowers were wilting on the walls. Leona Lalage had discarded her dress for a fascinating wrap, and was seated in her boudoir making a cigarette and trying to read something from the expression of Lawrence's face. FORE:1. Never seen anything of a franc-tireur-guerilla.

ONE:Let the reader compare a hammer with a wheel and axle, inclined plane, screw, or lever, as an agent for concentrating and applying power, noting the principles of its action first, and then considering its universal use, and he will conclude that, if there is a mechanical device that comprehends distinct principles, that device is the common hammer. It seems, indeed, to be one of those provisions to meet a human necessity, and without which mechanical industry could not be carried on. In the manipulation of nearly every kind of material, the hammer is continually necessary in order to exert a force beyond what the hands may do, unaided by mechanism to multiply their force. A carpenter in driving a spike requires a force of from one to two tons; a blacksmith requires a force of from five pounds to five tons to meet the requirements of his work; a stonemason applies a force of from one hundred to one thousand pounds in driving the edge of his tools; chipping, calking, in fact nearly all mechanical operations, consist more or less in blows, such blows being the application of accumulated force expended throughout a limited distance.

ONE:"Well," Prout said thoughtfully, "seeing that you were traced to Lytton Avenue, I suppose that you found her there?"

ONE:Returning to Epicurus, we have next to consider how he obtained the various motions required to bring his atoms into those infinite combinations of which our world is only the most recent. The conception of matter naturally endowed with capacities for moving in all directions indifferently was unknown to ancient physics, as was also that of mutual attraction and85 repulsion. Democritus supposed that the atoms all gravitated downward through infinite space, but with different velocities, so that the lighter were perpetually overtaken and driven upwards by the heavier, the result of these collisions and pressures being a vortex whence the world as we see it has proceeded.163 While the atomism of Democritus was, as a theory of matter, the greatest contribution ever made to physical science by pure speculation, as a theory of motion it was open to at least three insuperable objections. Passing over the difficulty of a perpetual movement through space in one direction only, there remained the self-contradictory assumption that an infinite number of atoms all moving together in that one direction could find any unoccupied space to fall into.164 Secondly, astronomical discoveries, establishing as they did the sphericity of the earth, had for ever disproved the crude theory that unsupported bodies fall downward in parallel straight lines. Even granting that the astronomers, in the absence of complete empirical verification, could not prove their whole contention, they could at any rate prove enough of it to destroy the notion of parallel descent; for the varying elevation of the pole-star demonstrated the curvature of the earth��s surface so far as it was accessible to observation, thus showing that, within the limits of experience, gravitation acted along convergent lines. Finally, Aristotle had pointed out that the observed differences in the velocity of falling bodies were due to the atmospheric resistance, and that, consequently, they would all move at the same rate in such an absolute vacuum as atomism assumed.165 Of these objections Epicurus ignored the first two, except, apparently, to the extent of refusing to believe in the antipodes. The third he acknowledged, and set himself to evade it by a hypothesis striking at the root of all scientific86 reasoning. The atoms, he tells us, suffer a slight deflection from the line of perpendicular descent, sufficient to bring them into collision with one another; and from this collision proceeds the variety of movement necessary to throw them into all sorts of accidental combinations. Our own free will, says Lucretius, furnishes an example of such a deflection whenever we swerve aside from the direction in which an original impulse is carrying us.166 That the irregularity thus introduced into Nature interfered with the law of universal causation was an additional recommendation of it in the eyes of Epicurus, who, as we have already mentioned, hated the physical necessity of the philosophers even more than he hated the watchful interfering providence of the theologians. But, apparently, neither he nor his disciples saw that in discarding the invariable sequence of phenomena, they annulled, to the same extent, the possibility of human foresight and adaptation of means to ends. There was no reason why the deflection, having once occurred, should not be repeated infinitely often, each time producing effects of incalculable extent. And a further inconsequence of the system is that it afterwards accounts for human choice by a mechanism which has nothing to do with free-will.167

THREE:Or strong Necessity, or Nature��s teaching

ONE:It was quiet enough in Churton Street. And again in Collin's Crescent, which was so near home that the long line of Lytton Avenue could be seen. But there again standing figures came out of the gloom and the car sped on.Temperance and justice are very clearly distinguished in our minds. The one is mainly a self-regarding, the other mainly a social virtue. But it would be a mistake to suppose that the distinction was equally clear to Plato. He had learned from Socrates that all virtue is one. He found himself confronted by men who pointedly opposed interest to honour and expediency to fair-dealing, without making any secret of their preference for the former. Here, as elsewhere, he laboured to dissolve away the vulgar antithesis and to231 substitute for it a deeper one��the antithesis between real and apparent goods. He was quite ready to imagine the case of a man who might have to incur all sorts of suffering in the practice of justice even to the extent of infamy, torture, and death; but without denying that these were evils, he held that to practise injustice with the accompaniment of worldly prosperity was a greater evil still. And this conviction is quite unconnected with his belief in a future life. He would not have agreed with St. Paul that virtue is a bad calculation without the hope of a reward for it hereafter. His morality is absolutely independent of any extrinsic considerations. Nevertheless, he holds that in our own interest we should do what is right; and it never seems to have entered his thoughts that there could be any other motive for doing it. We have to explain how such a paradox was possible.

A few guests of the higher Bohemian type still lingered, but with easy tact the hostess contrived to get rid of them. Her absence had not been noticed, the little escapade on the motor was not mentioned.60
