212. It is easy to see that in all metaphysical and mathematical truths, identity is expressed or denied. All formulas are reduced to A is B, or A is not B; this is the general formula of all truths of an absolute order. But it is otherwise in the moral order, where nothing is ever expressed absolutely, as is shown by the very form of the propositions. God is good, expresses a metaphysical truth, God must be loved, or in other words, we ought to love God, expresses a moral truth. Note the difference: in one case we say is absolutely; in the other, must be, ought to be, there is obligation, etc., using different expressions which all mean the same thing; but in all, the verb to be, as an absolute affirmation, disappears. It seems that no moral proposition could be thus expressed, if we regard the primitive elements of our moral ideas; for all these propositions express the idea of duty, which is essentially a relative idea.
213. To love God is good. This is a moral proposition whose structure seems to contradict what I have just established. Here an absolute affirmation is found expressed simply by is, as in metaphysical or mathematical propositions. Still, the least reflection will suffice to show that this absolute character is destroyed by the nature of the predicate. What is the meaning of good? Here we have an essentially relative idea which communicates this character to the proposition. To love God is good, is the same as: to love God is a thing conformed to reason, or to the eternal law, or pleasing to God, or a thing which we are under obligation to do; it is always a relative idea, and never absolute, like being, not-being, a triangle, a circle, etc.
214. Good, say some, is that which leads to the end which corresponds to intelligent beings. This explanation must not be confounded with the theory of private interest;—a theory alike rejected by religion and by the sentiments of the heart, and combated by the most profound thinkers;—here, in speaking of end, the last end is meant, which is something superior to what is understood by the expression, private interest. Without doubt, to arrive at the last end, is a great interest of every intelligent being; but at least this interest is taken in an elevated sense, and does not promote the development of a paltry egotism.
Having thus designated the difference between these doctrines, I say that not even the latter seems to me admissible. Moral good must lead to the end; but this does not constitute the character of morality. For, what is meant by end? If God himself is meant, a moral act is that which leads to God; in which case the difficulty still remains, for we again ask, what is meant by leading? If it means to conduce to the happiness which consists in a union with God, how does it conduce to this happiness? By the performance of what God has commanded;—certainly; but then we ask: I. Why does doing what God has commanded conduce to happiness? II. Why has God commanded some things and prohibited others?—which is equivalent to putting anew the question of intrinsic morality.
215. Besides, the idea of happiness represents something very different from the idea of morality. Imagining a being which sacrifices all that it possessed for the sake of other beings, we have the idea of a highly moral being, but not a happy being. If morality consisted in happiness, the participation of happiness would be the participation of morality; every enjoyment would be a moral act; and could only be immoral because too short or feeble. In proportion as we rose to the idea of a stronger and more lasting enjoyment, we should form the idea of a more elevated morality; the enjoyment the most free from trouble would be the purest act of morality; who does not see that this overthrows all our moral ideas, and is repugnant to every sentiment of the heart?
216. It is not enough to say that a moral being will obtain happiness, and that its happiness will be great in proportion to its morality; this only proves that happiness is the reward of morality; it does not authorize us to confound the two, the guerdon with the merit.
217. To confound morality with happiness is to reduce morality to a calculation, to strip virtue of the pure lustre which charms and attracts us, and makes it appear more beautiful accordingly as it is joined with greater suffering. If we identify happiness with morality, disinterestedness becomes a calculation of interest, a sacrifice of a smaller to a greater interest, a loss for the present to gain in the future.
No! the morality of actions is not an affair of calculation: the virtuous man obtains a reward; but, in order that the act may be virtuous, something more is necessary than a combination for the purpose of obtaining it; there must be something which makes the act merit the reward; and we cannot even conceive that a reward can be reserved for any act, unless the act is in itself meritorious.
When God prepared punishment for some acts and rewards for others, he must have found an intrinsic difference in them; and therefore he gave them different destinies; but, according to the systems which we are opposing, acts could be good only inasmuch as they lead to a reward, and there would be no reason why some should lead to it rather than others. This reason must be found in an intrinsic difference in the acts themselves; or we fall into the absurdity of saying that all actions are in themselves indifferent, and the good may be evil, and the evil good.
218. To lead to the good of mankind is another incomplete character of the morality of actions. It is clear that this morality would be only human, and would not include the intrinsic morality which we consider common to all intelligent beings.
