ONE:An energy continually advancing through successive gradations, and diminishing as it advancessuch, as we have seen, is the conception of existence offered by Plotinus. We have seen, also, how to explain the genesis of one principle from another without the aid of supernatural volition or of mechanical causation, he is compelled to press into the service every sort of relationship by which two objects can be connected, and to invest it with a dynamical significance which only the phenomena of matter and motion can possess. But what he chiefly relies on for guidance in this tortuous labyrinth of timeless evolution, is the old Greek principle that contraries are generated from one another. And with him, as with the earlier thinkers, all contraries reduce themselves, in the last analysis, to the four great antitheses of the One and the Many, Being and not-Being, the Same and the Other, Rest and Motion. It matters nothing that he should have followed Plato to the extent of co-ordinating five of these terms as supreme archetypal Ideas, immediately resulting from the self-consciousness of Nous, and themselves producing all other forms of existence. They are used, quite independently of that derivation, to explain the connexion of the various323 creative principles with one another. Nous is deduced from its first cause as Being from not-Being, as the Many from the One, as Difference from Identity, and as Motion from Rest.474 To explain the generation of Soul from Nous is a more difficult problem. The One had originally been defined as the antithetical cause of Nous, and therefore the latter could easily be accounted for by simply reversing the analytical process; whereas Nous had not been defined as the cause of Soul, but as the model whence her creative Ideas are derived. Soul, in fact, is not opposed to anything; she is the connecting link between sense and spirit. In this strait, Plotinus seems to think that the antithesis between Rest and Motion is the best fitted to express the nature of her descent from the higher principle; and on one occasion he illustrates the relation of his three divine substances to one another by the famous figure of a central point representing the One, a fixed circle round that point representing the Nous, and outside that, again, a revolving circle representing the Soul.475 Still, the different parts of the system are very awkwardly pieced together at this juncture; for the creative energy of the Nous has already been invoked to account for the Ideas or partial intelligences into which it spontaneously divides; and one does not understand how it can be simultaneously applied to the production of something that is not an Idea at all.
FORE:A strong desire for reform must always be preceded by a deep dissatisfaction with things as they are; and if the reform is to be very sweeping the discontent must be equally comprehensive. Hence the great renovators of human life have been remarkable for the severity with which they have denounced the failings of the world where they were placed, whether as regards persons, habits, institutions, or beliefs. Yet to speak of their attitude as pessimistic would either be unfair, or would betray an unpardonable inability to discriminate between two utterly different theories of existence. Nothing can well be more unlike the systematised pusillanimity of those lost souls, without courage and without hope, who find a consolation for their own failure in the belief that everything193 is a failure, than the fiery energy which is drawn into a perpetual tension by the contrast of what is with the vision of what yet may be. But if pessimism paralyses every generous effort and aspiration by teaching that misery is the irremediable lot of animated beings, or even, in the last analysis, of all being, the opposing theory of optimism exercises as deadly an influence when it induces men to believe that their present condition is, on the whole, a satisfactory one, or that at worst wrong will be righted without any criticism or interference on their part. Even those who believe progress to have been, so far, the most certain fact in human history, cannot blind themselves to the existence of enormous forces ever tending to draw society back into the barbarism and brutality of its primitive condition; and they know also, that whatever ground we have won is due to the efforts of a small minority, who were never weary of urging forward their more sluggish companions, without caring what angry susceptibilities they might arouserisking recrimination, insult, and outrage, so that only, under whatever form, whether of divine mandate or of scientific demonstration, the message of humanity to her children might be delivered in time. Nor is it only with immobility that they have had to contend. Gains in one direction are frequently balanced by losses in another; while at certain periods there is a distinct retrogression along the whole line. And it is well if, amid the general decline to a lower level, sinister voices are not heard proclaiming that the multitude may safely trust to their own promptings, and that self-indulgence or self-will should be the only law of life. It is also on such occasions that the rallying cry is most needed, and that the born leaders of civilisation must put forth their most strenuous efforts to arrest the disheartened fugitives and to denounce the treacherous guides. It was in this aspect that Plato viewed his age; and he set himself to continue the task which Socrates had attempted, but had been trampled down in endeavouring to achieve.
