THREE: Above all, he exclaims, we must not fail to notice what effect this doctrine has on the minds of those whom they have persuaded to despise the world and all that it contains. Of the two chief methods for attaining the supreme good, one has sensual pleasure for its end, the other virtue, the effort after which begins and ends with God. Epicurus, by his denial of providence, leaves us no choice but to pursue the former. But this doctrine [Gnosticism], involving as it does a still more insolent denial of divine order and human law, laughs to scorn what has always been the accepted ideal of conduct, and, in its rage against beauty, abolishes temperance and justicethe justice that is associated with natural feeling and perpetuated by discipline and reasonalong with every other ennobling virtue. So, in the absence of true morality, they are given over to pleasure and utility and selfish isolation from other menunless, indeed, their nature is better than their principles. They have an ideal that nothing here below can satisfy, and so they put off the effort for its attainment to a future life, whereas they should begin at once, and prove that they are of divine race by fulfilling the duties of their present state. For virtue is the condition of every higher aspiration, and only to those who disdain sensual enjoyment is it given to understand the divine. How far our opponents are from realising this is proved by their349 total neglect of ethical science. They neither know what virtue is, nor how many virtues there are, nor what ancient philosophy has to teach us on the subject, nor what are the methods of moral training, nor how the soul is to be tended and cleansed. They tell us to look to God; but merely saying this is useless unless they can tell us what the manner of the looking is to be. For it might be asked, what is to prevent us from looking to God, while at the same time freely indulging our sensual appetites and angry passions. Virtue perfected, enlightened, and rooted in the soul, will reveal God to us, but without it he will remain an empty name.521It has been already mentioned how large a place was given to erotic questions by the literary Platonists of the second century. Even in the school of Plotinus, Platonic love continued to be discussed, sometimes with a freedom which pained and disgusted the master beyond measure.431 His first essay was apparently suggested by a question put to him in the course of some such debate.432 The subject is beauty. In his treatment of it, we find our philosopher at once rising superior to the indecorous frivolities of his predecessors. Physical beauty he declares to be the ideal element in objects, that which they have received from the creative soul, and which the perceptive soul recognises as akin to her own essence. Love is nothing but the excitement and joy occasioned by this discovery. But to understand the truer and higher forms of beauty, we must turn away288 from sensible perceptions, and study it as manifested in wise institutions, virtuous habits, and scientific theories. The passionate enthusiasm excited by the contemplation of such qualities as magnanimity, or justice, or wisdom, or valour can only be explained by assuming that they reveal our inmost nature, showing us what we were destined for, what we originally were, and what we have ceased to be. For we need only enumerate the vices which make a soul hideousinjustice, sensuality, cowardice, and the liketo perceive that they are foreign to her real nature, and are imposed on her by contamination with the principle of all evil, which is matter. To be brave means not to dread death, because death is the separation of the soul from the body. Magnanimity means the neglect of earthly interests. Wisdom means the elevation of our thoughts to a higher world. The soul that virtue has thus released becomes pure reason, and reason is just what constitutes her intrinsic beauty. It is also what alone really exists; without it all the rest of Nature is nothing. Thus foul is opposed to fair, as evil to good and false to true. Once more, as the soul is beautiful by participation in reason, so reason in its turn depends on a still higher principle, the absolute good to which all things aspire, and from which they are derivedthe one source of life, of reason, and of existence. Behind all other loves is the longing for this ultimate good; and in proportion to its superiority over their objects is the intensity of the passion which it inspires, the happiness which its attainment and fruition must bestow. He who would behold this supreme beauty must not seek for it in the fair forms of the external world, for these are but the images and shadows of its glory. It can only be seen with the inward eye, only found in the recesses of our own soul. To comprehend the good we must be good ourselves; or, what is the same thing, we must be ourselves and nothing else. In this process of abstraction, we first arrive at pure reason, and then we say that the ideas289 of reason are what constitutes beauty. But beyond reason is that highest good of which beauty is merely the outward vesture, the source and principle from which beauty springs.
