conception of the good is fundamentally the same. It is a full development of man's capacities, culminating in a rational and harmonious life. If, says Aristotle, we are to find the ultimate good, we must try to find, if possible, some one end which is pursued as an end in itself, and never as a means to something else, and the most general term for this final end is "eudaimonia," or well-being, "for we also choose it for itself and never for the sake of something else." What is the essence of well-being? This, according to Aristotle, is to be found by asking what is the function of man. The life of nutrition and growth man has in common with the plants; the life of sense in common with the animal. It is in the life of his rational nature that we must find his especial function. "The good of man is exercise of his faculties in accordance with their appropriate excellence." External goods are valuable because they may be instruments toward such full activity. Pleasure is to be valued because it "perfects the activities, and therefore perfects life, which is the aim of human desire"—rather than valued as an end in itself. No one would choose to live on condition of having a child's intellect all his life, though he were to enjoy in the highest possible degree all the pleasures of a child.[78]
The "Mean."—The crowning importance of wisdom as the rational measure of the ideal life is also illustrated in Aristotle's theory of excellence (or virtue) as a "mean". This phrase is somewhat ambiguous, for some passages would seem to indicate that it is merely striking an average between two kinds of excesses, and finding, as it were, a moderate amount of feeling or action; but there is evidently involved here just the old thought of measure, and "the mean is what right reason prescribes." It is not every one who can find the mean, but only he who has the requisite knowledge. The supreme excellence or virtue is, therefore, the wisdom which can find the true standard for action.[79]
The Wise Man.—Finally the conception of virtue as wisdom is illustrated in the ideals of the three prominent schools in later Greek thought—the Sceptics, Epicureans, and Stoics. The wise man among Sceptics is he who suspends judgment where it is impossible to be certain. The wise man among Epicureans is he who chooses the finest and surest and most lasting pleasures. The wise man among Stoics is he who overcomes his emotions. But in every case the ideal is expressed in the same phrase, "the wise man."
Man and the Cosmos.—We see thus how Greek thought, starting out to challenge all society's laws and standards and bring them to the bar of knowledge, has found a deeper value and higher validity in the true social and moral order. The appeal was to the Cæsar of reason, and reason taken in its full significance carries us beyond the immediate and transient to the broader and more permanent good. Nor can reason in its search for good be content, urges Plato, with the superficial facts of life and society. He who would find and achieve his complete function, his full development, must broaden his horizon still further. As his own particular life is but a part of the ongoing of the larger world, whose forces act upon him, limit him, and determine his possibilities, it becomes absolutely necessary to study not merely his own end and purpose, but the end and purpose of the universe. Human good requires us to know the larger good, the Good, in the full and complete sense. And this perfect Good which is, in truth, the very essence of the universe, is but another term for God, and Plato often uses the two as interchangeable terms.
So the "Nature" which Greek life was seeking gets its deepest significance and reinterprets the old religious demand for unity of the life of man with the forces of the unseen. And the Stoic later, in his maxim "Follow Nature," gives more explicit recognition to the return of the circle. For the great work of Greek science had brought out into complete clearness the idea of Nature as a system of law. The universe is a rational universe, a cosmos, and man, as above all else a rational being, finds thus his kinship to the universe. To follow Nature, therefore, means to know the all-pervading law of Nature and submit to it in calm acceptance or resignation.
"All is harmonious to me that is harmonious to thee, O universe; all is fruit to me which thy seasons bring."[80]
§ 6. THE CONCEPTION OF THE IDEAL
Contrast of Actual and Ideal.—The two stages of Greek thought which we have sketched did more than to readjust Greek life to deeper views of the State and the individual; of the good and of nature. The very challenge and process brought into explicit consciousness a new feature of the moral life, which is fundamental to true moral consciousness, viz., the factor of contrast between the actual and the ideal. We have seen that the clash of one-sided interests and political institutions and, in the case of Plato, the tragic execution of Socrates, obliged Plato and Aristotle to admit that the actual State did not subserve the real purpose which they were forced to seek in social organization. Both Plato and Aristotle, therefore, draw the picture of a State that should serve the complete purposes of human development. And again, in the individual life, both the conception of the development of man's highest possibilities and the conception of a measure or standard for the conflicting desires and purposes lead on to a conception which shall embody not merely the existing status but the goal of yet unrealized purpose.
The Ideal as the True Reality.—Various qualities and aspirations are embodied by Plato in this conception, and with characteristic Greek genius he has given to this conception of the ideal almost as concrete and definite a form as the Greek sculptor of Apollo gave to his ideal of light and clarity, or the sculptor of Aphrodite to the conception of grace. As contrasted with the flux of transient emotions, or the uncertain play of half-comprehended or futile goods, this ideal good is conceived as eternal, unchanging, ever the same. It is superhuman and divine. As contrasted with various particular and partial goods on which the sons of men fix their affections, it is the one universal good which is valid for all men everywhere and forever. In his effort to find suitable imagery for this conception, Plato was aided by the religious conceptions of the Orphic and Pythagorean societies, which had emphasized the pre-existence and future existence of the soul, and its distinction from the body. In its previous life, said Plato, the soul has had visions of a beauty, a truth, and a goodness of which this life affords no adequate examples. And with this memory within it of what it has looked upon before, it judges the imperfect and finite goods of this present world and longs to fly away again and be with God. This thought of contrast between ideal and actual, to which Plato in some of his writings gave the turn of a contrast between soul and body, passed on with increased emphasis into Stoic and later Platonist schools, and furnished a philosophic basis for the dualism and asceticism which is found in Hellenistic and mediæval morality.
Ethical Significance.—While the true ethical contrast between the actual and the ideal was thus shifted over into a metaphysical contrast between soul and body, or between what is fixed and what is changing, the fundamental thought is highly significant, for it merely symbolizes in objective form the characteristic of every moral judgment, viz., the testing and valuing of an act by some standard, and what is even more important, the forming of a standard by which to do the testing. Even Aristotle, who is frequently regarded as the mere describer of what is, rather than the idealistic portrayer of what ought to be, is no less insistent upon the significance of the ideal. In fact, his isolation of reflection or theoria from the civic virtues was used by the mediæval church in its idealization of the "contemplative life." Like Plato, he conceives the ideal as a divine element in human nature:
"Nevertheless, instead of listening to those who advise us as men and mortals not to lift our thoughts above what is human and mortal, we ought rather, as far as possible, to put off our mortality and make every effort to live in the exercise of the highest of our faculties; for though it be but a small part of us, yet in power and value it far surpasses all the rest."[81]
