If we are not mistaken, the difficulty is solved in a manner perfectly analogous to that in which is solved the problem of the relations between expression and concept, Æsthetic and Logic.
To will economically is to will an end; to will morally is to will the rational end. But whoever wills and acts morally, cannot but will and act usefully (economically). How could he will the rational end, unless he also willed it as his particular end?
Pure economicity.
The converse is not true; as it is not true in æsthetic science that the expressive fact must of necessity be linked with the logical fact. It is possible to will economically without willing morally; and it is possible to conduct oneself with perfect economic coherence, while pursuing an end which is objectively irrational (immoral), or, rather, an end which would be held to be so at a higher grade of consciousness.
Examples of the economic, without the moral character, are Machiavelli's hero Cæsar Borgia, or the Iago of Shakespeare. Who can help admiring their strength of will, although their activity is only economic, and is developed in opposition to what we hold moral? Who can help admiring the Ser Ciappelletto of Boccaccio, who pursues and realizes his ideal of the perfect rascal even on his death-bed, making the petty and timid little thieves who are present at his burlesque confession exclaim: "What manner of man is this, whose perversity neither age, nor infirmity, nor the fear of death which he sees at hand, nor the fear of God before whose judgement-seat he must stand in a little while, have been able to remove, nor to make him wish to die otherwise than as he has lived?"
The economic side of morality.
The moral man unites with the pertinacity and fearlessness of a Cæsar Borgia, of an Iago, or of a Ser Ciappelletto, the good will of the saint or of the hero. Or, rather, good will would not be will, and consequently not good, if it did not possess, in addition to the side which makes it good, also that which makes it will. So a logical thought which does not succeed in expressing itself is not thought, but at the most a confused presentiment of a thought beyond yet to come.
It is not correct, then, to conceive of the amoral man as also anti-economical, or to make of morality an element of coherence in the acts of life, and therefore of economicity. Nothing prevents us from conceiving (an hypothesis which is verified at least during certain periods and moments, if not during whole lifetimes) a man altogether without moral conscience. In a man thus organized, what for us is immorality is not so for him, because it is not felt as such. The consciousness of the contradiction between what is desired as a rational end and what is pursued egoistically cannot arise in him. This contradiction is anti-economicity. Immoral conduct becomes also anti-economical only in the man who possesses moral conscience. The moral remorse which is the indication of this, is also economical remorse; that is to say, sorrow at not having known how to will completely and to attain that moral ideal which was willed at first, instead of allowing himself to be led astray by the passions. Video meliora proboque, deteriora sequor. The video and the probo are here an initial volo immediately contradicted and overthrown. In the man without moral sense, we must admit a remorse that is merely economic; like that of a thief or of an assassin who, when on the point of robbing or of assassinating should abstain from doing so, not owing to a conversion of his being, but to nervousness and bewilderment, or even to a momentary awakening of moral consciousness. When he has come back to himself, such a thief or assassin will regret and be ashamed of his incoherence; his remorse will not be due to having done wrong, but to not having done wrong; it is therefore economic, not moral, since the latter is excluded by hypothesis. But since a lively moral consciousness is generally found among the majority of men and its total absence is a rare and perhaps non-existent monstrosity, it may be admitted that morality, in general, coincides with economicity in the conduct of life.
The merely economic and the error of the morally indifferent.
There need be no fear lest the parallelism that we support should introduce afresh into science the category of the morally indifferent, of that which is in truth action and volition, but is neither moral nor immoral; the category in short of the licit and of the permissible, which has always been the cause or reflexion of ethical corruption, as was the case with Jesuitical morality, which it dominated. It remains quite certain that indifferent moral actions do not exist, because moral activity pervades and must pervade every least volitional movement of man. But far from upsetting the established parallelism, this confirms it. Are there by any chance intuitions which science and the intellect do not pervade and analyse, resolving them into universal concepts, or changing them into historical affirmations? We have already seen that true science, philosophy, knows no external limits which bar its way, as happens with the so-called natural sciences. Science and morality entirely dominate, the one the æsthetic intuitions, the other the economic volitions of man, although neither of them can appear in the concrete, save the one in the intuitive, the other in the economic form.
