b. The other side as regards the good is external existence, and the agreement of circumstances, of external nature, with the end aimed at by man. For although the Stoics have expressed the good as being conformity with law, in relation to the practical will, they yet defined it, according to Diogenes Laërtius (VII. 94, 95), as being at the same time the useful, “either absolutely and immediately useful or not contrary to utility,” so that generally speaking the useful is, as it were, the accident of virtue. “The Stoics likewise distinguished manifold good into good having reference to the soul, and external good; the former indicates virtues and their actions; the latter the fact of pertaining to a noble country, having a virtuous friend, and so on. In the third place it is neither external nor is it a matter of self-consciousness alone, when the self-same man is virtuous and happy.” These conclusions are quite good. Morality does not require to look so coldly on what concerns utility, for every good action is in fact useful, _i.e._ it has actuality and brings forth something good. An action which is good without being useful is no action and has no actuality. That which in itself is useless in the good is its abstraction as being a non-reality. Men not only may, but must have the consciousness of utility; for it is true that it is useful to know the good. Utility means nothing else but that men have a consciousness respecting their actions. If this consciousness is blameworthy, it is still more so to know much of the good of one’s action and to consider it less in the form of necessity. Thus the question was raised as to how virtue and happiness are related to one another, a theme of which the Epicureans have also treated. Here it was, as in more recent times, regarded as the great problem to discover whether virtue gives happiness, taken altogether by itself, whether the conception of happiness is included in its conception. That union of virtue and happiness, as the mean, is thus rightly represented as being perfect, neither pertaining only to self-consciousness nor to externality.
