FORE:The next great forward step in speculation was taken by Anaximander, another Milesian, also of distinguished attainments in mathematics and astronomy. We have seen that to Thales water, the all-embracing element, became, as such, the first cause of all things, the absolute principle of existence. His successor adopted the same general point of view, but looked out from it with a more penetrating gaze. Beyond water lay something else which he called the Infinite. He did not mean the empty abstraction which has stalked about in modern times under that ill-omened name, nor yet did he mean infinite space, but something richer and more concrete than either; a storehouse of materials whence the waste of existence could be perpetually made good. The growth and decay of individual forms involve a ceaseless drain on Nature, and the deficiency must be supplied by a corresponding influx from without.A For, be it observed that, although the Greek thinkers were at this period well aware that nothing can come from nothing, they had not yet grasped the complementary truth inalienably wedded to it by Lucretius in one immortal couplet, that nothing can return to nothing; and Kant is quite mistaken when he treats the two as historically inseparable. Common experience forces the one on our attention much sooner than the other. Our incomings are very strictly measured out and accounted for without difficulty, while it is hard to tell what becomes of all our expenditure, physical and economical. Yet, although the indestructibility of matter was a conception which had not yet dawned on Anaximander, he seems to have been feeling his way towards the recognition of a circulatory movement pervading all Nature. Everything, he says, must at last be reabsorbed in the Infinite as a punishment for the sin of its separate existence.10 Some may find in this sentiment a note of Oriental10 mysticism. Rather does its very sadness illustrate the healthy vitality of Greek feeling, to which absorption seemed like the punishment of a crime against the absolute, and not, as to so many Asiatics, the crown and consummation of spiritual perfection. Be this as it may, a doctrine which identified the death of the whole world with its reabsorption into a higher reality would soon suggest the idea that its component parts vanish only to reappear in new combinations.We have seen how, in accordance with this view, each principle is perfected by looking back on its source.491 Thus330 the activity of the world-soul, so far as it is exercised for the benefit of what comes after and falls beneath her, is an anomaly only to be accounted for by her inferior place in the system of graduated descent; or else by the utter impotence of Matter, which is incapable of raising itself into Form by a spontaneous act of reflection, and can only passively receive the images transmitted to it from above, without being able to retain even these for any time. Nay, here also, what looks like creative energy admits of being assimilated more or less closely to an exercise of idealising thought. It is really for her own sake that the Soul fills what lies beyond her with life and light, not, like Platos Soul, from pure disinterested joy in the communication and diffusion of good. It is because she recoils with horror from darkness and nonentity that she shapes the formless substance into a residence for herself, on the model of the imperial palace whence she came. Thus the functions of sensation, nutrition, and reproduction are to be regarded as so many modes of contemplation. In the first, the Soul dwells on the material images which already exist; in the second and third, she strives to perpetuate and multiply them still further. And the danger is that she may become so enthralled by her own creation as to forget the divine original after which it is formed.492 Should she yield to the snare, successive transmigrations will sink her lower and lower into the depths of animalism and material darkness. To avoid this degradation, to energise with the better part of our nature, is to be good. And with the distinction between good and evil, we pass from the metaphysical to the ethical portion of the system.
FORE:Closely connected with the materialism of the Stoics, and equally adverse to the principles of Plato and Aristotle, was their fatalism. In opposition to this, Plotinus proceeds to develop the spiritualistic doctrine of free-will.438 In the previous discussion, we had to notice how closely his arguments resemble those employed by more modern controversialists. We have here to point out no less wide a difference between the two. Instead of presenting free-will as a fact of consciousness which is itself irreconcilable with the dependence of mental on material changes, our philosopher, conversely, infers that the soul must be free both from the conditions of mechanical causation and from the general interdependence of natural forces, because it is an individual substance.439 In truth, the phenomena of volition were handled by the ancient philosophers with a vagueness and a feebleness offering the most singular contrast to their powerful and discriminating grasp of other psychological problems. Of necessarianism, in the modern sense, they had no idea. Aristotle failed to see that, quite apart from external restraints, our choice may conceivably be determined with the utmost rigour by an internal motive; nor could he understand that the circumstances which make a man responsible for his actions do not amount to a release of his conduct from the law of universal causation. In this respect, Plato saw somewhat deeper than his disciple, but created298 fresh confusion by identifying freedom with the supremacy of reason over irrational desire.440 Plotinus generally adopts the Platonist point of view. According to this, the soul is free when she is extricated from the bonds of matter, and determined solely by the conditions of her spiritual existence. Thus virtue is not so much free as identical with freedom; while, contrariwise, vice means enslavement to the affections of the body, and therefore comes under the domain of material causation.441 Yet, again, in criticising the fatalistic theories which represent human actions as entirely predetermined by divine providence, he protests against the ascription of so much that is evil to so good a source, and insists that at least the bad actions of men are due to their own free choice.442The traction of belts upon pulleys, like that of locomotive wheels upon railways, being incapable of demonstration except by actual experience, for a long time hindered the introduction of belts as a means of transmitting motion and power except in cases when gearing or shafts could not be employed. Motion is named separately, because with many kinds of machinery that are driven at high speedsuch as wood machinesthe transmission of rapid movement must be considered as well as power, and in ordinary practice it is only by means of belts that such high speeds may be communicated from one shaft to another.
