(3.) This abstract apprehension of the conception of virtue is still farther verified in the rigid antagonism which the Stoics affirmed between virtue and not-virtue, reason and sense. Either, they conclude, reason is awakened in the life of man and holds the mastery over him, or it is not awakened, and he serves his irrational instincts. In the former case we have a good and in the latter a bad man, while between these two cases as between virtue and vice, there is no mean. And since virtue cannot be partially possessed, but the man must be wholly virtuous or not at all, it follows that virtue as such is without degree, just as truth is, and hence also all good acts are equally good, because they spring from the full freedom of the reason, and all vicious ones equally bad, because they are impelled by the irrational instinct. (4.) But this abstractedness of the moral standpoint, this rigid opposition of reason and irrationality, of the highest good and the individual good, of virtue and pleasure, has no power to furnish a system of concrete moral duties. The universal moral principle of the Stoics fails in its applicability to the individual instance. The Stoic morals has no concrete principle of moral self-determination. How must we act in every individual instance, in every moral relation, so as to act according to nature? To this inquiry Stoicism can give no answer. Its system of particular duties is thus wholly without a scientific form, and is only held together by some universal conceptions which it contains. For the most part they satisfy themselves with describing in general terms the action according to nature, and with portraying their ideal of the wise man. The characteristics which they give this ideal are partly paradoxical. The wise man is free even in chains, for he acts from himself unmoved by fear or desire; the wise man alone is king, for he alone is not bound by laws and owes fealty to no one; he is the true rich man, the true priest, prophet, and poet. He is exalted above all law and every custom; even that which is most despicable and base—deception, suicide, murder—he may commit at a proper time and in a virtuous character. In a word the Stoics describe their wise man as a god, and yield it to him to be proud and to boast of his life like Zeus. But where shall we find such a sage? Certainly not among the living. In the time long ago there may have been a perfect sage of such a pattern; but now, and for a long time back, are men at best only fools who strive after wisdom and virtue. The conception of the wise man represented, therefore, to the Stoics only an ideal, the actualization of which we should strive after, though without ever hoping to reach it; and yet their system of particular duties is almost wholly occupied in portraying this unreal and abstract ideal—a contradiction in which it is seen most clearly that their whole standpoint is one of abstract subjectivity.
