In regard to the conception of virtue I should like to say something more. From a practical point of view, Aristotle[104] first of all distinguishes in soul a rational and an irrational side; in the latter reason only exists potentially; under it come the feelings, passions and affections. On the rational side understanding, wisdom, discretion, knowledge, have their place; but they still do not constitute virtue, which first subsists in the unity of the rational and the irrational sides. When the inclinations are so related to virtue that they carry out its dictates, this, according to Aristotle, is virtue. When the perception is either bad or altogether lacking, but the heart is good, goodwill may be there, but not virtue, because the principle—that is reason—which is essential to virtue, is wanting. Aristotle thus places virtue in knowledge, yet reason is not, as many believe, the principle of virtue purely in itself, for it is rather the rational impulse towards what is good; both desire and reason are thus necessary moments in virtue. Hence it cannot be said of virtue that it is misemployed, for it itself is the employer. Thus Aristotle, as we have already seen (Vol. I. pp. 412-414), blames Socrates, because he places virtue in perception alone. There must be an irrational impulse towards what is good, but reason comes in addition as that which judges and determines the impulse; yet when a beginning from virtue has been made, it does not necessarily follow that the passions are in accordance, since often enough they are quite the reverse. Thus in virtue, because it has realization as its aim, and pertains to the individual, reason is not the solitary principle; for inclination is the force that impels, the particular, which as far as the practical side of the individual subject is concerned, is what makes for realization. But then the subject must, in this separation of his activity, bring likewise his passions under the subjection of the universal, and this unity, in which the rational is pre-eminent, is virtue. This is the correct determination; on the one hand this definition is opposed to these ideals of the utter subjection of the passions, by which men are guided from their youth up, and, on the other, it is opposed to the point of view that declares desires to be good in themselves. Both these extreme views have been frequent in modern times, just as sometimes we hear that the man who by nature is beauteous and noble, is better than he who acts from duty; and then it is said that duty must be performed as duty, without taking into account the particular point of view as a moment of the whole.
