treated both as different steps of development, and reversing the order of Socrates, made the rational enlightenment in moral things consequent upon the moral conduct. 2. THE HIGHEST GOOD.—Every action has an end; but since every end is only itself a means to some other, we need therefore something after which we can strive for its own sake, and which is a good absolutely, or a best. What now is this highest good and supreme object of human pursuit? In name, at least, all men are agreed upon it, and call it happiness, but what happiness is, is a much disputed point. If asked in what human happiness consists, the first characteristic given would be that it belongs alone to the peculiar being of man. But sensation is not peculiar to man, for he shares this with the brute. A sensation of pleasure, therefore, which arises when some desire is gratified, may be the happiness of the brute, but certainly does not constitute the essential of human happiness. Human happiness must express the completeness of intelligent existence, and because intelligence is essentially activity, therefore the happiness of man cannot consist in any merely passive condition, but must express a completeness of human action. Happiness therefore is a well-being, which is at the same time a well-doing, and it is a well-doing which satisfies all the conditions of nature, and which finds the highest contentment or well-being in an unrestrained energy. Activity and pleasure are thus inseparably bound together by a natural bond, and happiness is the result of their union when they are sustained through a perfect life. Hence the Aristotelian definition of happiness. It is a perfect practical activity in a perfect life.
