In much later times, and even down to our own days, the name of the Pythagorean school and science has been forced to serve as a cloak for every noxious farrago of mysticism, as also that of the Neo-Platonists has been made the symbol of every visionary extravagance. But even if (what, however, I greatly doubt) an historical connection can be shown to subsist between the so-called Pythagoreans of later times and the earlier and genuine school, nothing further would follow from such a fact, than a confirmation of my general position. It would but furnish an additional proof that all that is greatest, noblest, and most beautiful, when it once begins to degenerate and corrupt, invariably reaches a proportionate depth of corruption and degeneracy, and assumes the worst and wildest aspect of deformity.

As concerns the influence of this school of life, and its political aims and tendencies, which were unquestionably part of the general design of the Pythagorean doctrine: all this must be judged of in conformity with Greek notions and habits, and with reference to the unsettled and disordered state of the several Grecian communities. This being granted, it will appear that a simple but lofty object was the basis of their fraternity. By forming an enlightened aristocracy of highly cultivated minds, of men of scientific attainments, and of pure and noble morals, they hoped to establish a new and better polity, such as might check the reigning anarchy and revolutionary spirit of democracy, which distracted all the republics, whether smaller or greater, into which Greece was at that time divided. But the evil had become too great, and its power was irresistible. But the whole enterprise failed, and its failure entailed the dissolution of the Pythagorean society.

Many similar views and political designs, which Plato subsequently ingrafted on his own philosophy, in like manner remained nothing more than ideas, and led to no practical result. A far more considerable influence on life and its relations was exercised by the Sophists. Considered in a political point of view, they were truly and properly pernicious demagogues, and, in the fullest sense of the term, the flatterers of the populace. Not only did they undermine the outward national worship, with its poetical and hereditary associations, but also overthrew the inward religion of good principles and of moral sentiments. In short, they practically taught a true moral atheism, and succeeded in making it the prevailing and ruling principle in the conduct of life.

At this stage of Grecian philosophy, we witness, for the first time, a remarkable phenomenon. The true and good science which directs itself to the Godlike and divine, is unable to attain to any lasting or pervading influence on the lives of men: on the other hand, we see a false and evil sophistic gradually gaining a complete ascendency amid the general demoralization of society, and the growing anarchy of the political community, which, thoroughly corrupt and degenerate, only rose out of one revolution to fall immediately into another. Or, rather, this false sophistic, and this moral and political anarchy, were perfectly one together, so far at least as two destructive principles can ever be or be brought in unison.

The complete alienation which now existed between the better science and life, and especially public life, is most distinctly manifested in the case of the greatest among the Grecian philosophers of later times—in Aristotle, and the position he occupied in his own age and nation. This acute thinker, with the utmost care and diligence, collected together all the most eminent results of the science, and the most remarkable thoughts of earlier times. Examining and analyzing them with great critical acumen, and with a comprehensive survey, he formed them into a new whole, and arranged them into a system of his own, completer and fuller than had ever before been attempted or accomplished.

We can not, perhaps, estimate too highly or admire too much this great master of human subtilty, whether for his intellectual powers and extent of learning, or even as a writer. Still we must not forget that in his system were contained the germ and evident tendency to the two chief forms of philosophical error—naturalism on the one side, and rationalism on the other. And so we find that in the later times of the following centuries, each of these false systems, according as the occasion favored the one or the other, were drawn out from the Aristotelian doctrine, to receive a further and a distincter development. In his doctrine on the Godhead, he can least of all stand a severe and rigorous criticism. And in many points, as, for instance, in his notion of the absolute self-sufficiency of the reason, he approximates but too closely to the idealistic view which we have already designated as the transition to scientific atheism.

It was only in a very remote and distant age that Aristotle attained to a very great importance and authority. In his own day he did but form a very inconsiderable school, which exercised far less influence on public life than two other sects, in whose history the development of Grecian philosophy finds its close.

The system of the Stoics, with its stern and, consequently, impracticable theory of morals, its doctrine of absolute necessity and blind fatalism, announces itself at once as identical with an austere rationalism. At the same time, under the teaching of the Epicureans, a soft and effeminate naturalism became almost universally prevalent. And while, in another and newer form, it gradually assumed the place of the old mythical heathenism, which daily fell more and more into neglect and disrepute, it still retained the old heathen sentiment, and a careless and undisturbed indifference in inactive bliss and self-enjoyment, as it was even ascribed and imputed to the gods, was introduced into life, and extolled as the true wisdom. Thus, then, while on the one hand the foundation was laid for that insensibility with which the wide-spreading and growing corruption and the approach of the general ruin were contemplated, so, on the other hand, the apathy of the Stoics was not exactly the right kind of sentiment to furnish a check or counteractive to this sybaritic indifference.

As concerns the relations of public life, the social community, and the state, the Stoical doctrine appears, no doubt, in a worthier and a better light. On this account it numbered among its adherents almost all the great statesmen that lived from the last times of the Republic down to the later centuries of the Empire. Considered, however, in themselves, and scientifically regarded, both systems must be looked upon simply as the last chemical decomposing process, or the initiatory putrifying state of all higher science and philosophical reflection among the Greeks. On the whole, then, we conclude that Grecian science and philosophy have exercised no influence at all on life, or at least, either a very inadequate, or such as has proved radically baneful and pernicious.

But now, in the very center of man’s history—in the transition-point between the ancient and the modern world—science and life were again at unison, as at the beginning. And this was effected by the appearance of a new science in another form. For most assuredly we shall not err in giving this name to a new living and spiritual power, which, totally changing and giving an entirely new direction to the arbitrary views, sentiments, and principles of public and private life, and also to the modes of thinking prevalent in the age and in the world, was strong enough to triumph, not only over heathenism itself, but also over the science and philosophy of its most enlightened nations. Now this new mode of thinking, which came forward in the full certainty of the most undoubting faith and the highest internal illumination, had, so far as it is right and allowable to call it a science, a very different form and scope from all that has previously and usually been so called. For it issued out of the very depths of life, and received from love—a divine love, that is—its first diffusion and establishment. Consequently, it was a thoroughly living science, or, as being perfectly clear and certain in itself, a new scientific life, which, moreover, proceeded from this its first starting-point, was able to penetrate into all the other forms of public life and of the anterior systems of science, and by adopting or remodeling them, give to itself therein a further and more universal development.
