2. It is only of those acts of Will denominated Intentions, and of course ultimate intentions, that obligation, merit and demerit, are predicable.

In this last position, as I have already said, there is a universal agreement among moral philosophers. We may also safely assume the same as a first truth of the universal Intelligence. The child, the philosopher, the peasant, men of all classes, ages, and conditions, agree in predicating obligation and moral desert of intention, and of ultimate intention only. By ultimate intention, I, of course, refer to those acts, choices, or determinations of the Will, to which all other mental determinations are subordinate, and by which they are controlled. Thus, when an individual chooses, on the one hand, the Divine glory, and the highest good of universal being, as the end of his existence; or, on the other, his own personal gratification; and subordinates to one or the other of these acts of choice all the law of his being, here we find his ultimate intention. In this exclusively all mankind agree in finding the moral character of all mental acts and states.

Now an important question arises, By what standard shall we judge of the moral character of intentions? Of course, they are to be placed in the light of the two great precepts of the Moral law by which we are required to love God with all our powers, and our neighbor as ourselves. But two distinct and opposite explanations have been given of the above precepts, presenting entirely different standards of moral judgment. According to one, the precept requiring us to love God with all our heart and strength, requires a certain degree of intensity of intention and feeling. On no other condition, it is said, do we love God with all the heart.

According to the other explanation, the precept requiring us to love God with all the heart, &c., means, that we devote our entire powers and interests to the glory of God and the good of his creatures, with the sincere intention to employ these powers and interests for the accomplishment of these objects in the best possible manner. When all our powers are under the exclusive control of such an intention as this, we then, it is affirmed, love God according to the letter and spirit of the above precept, “with all our heart, and with all our strength.”

[SINCERITY, AND NOT INTENSITY, THE TRUE STANDARD.]

My object now is to show, that this last is the right exposition, and presents the only true standard by which to judge of all moral acts and states of mind. This I argue from the following considerations.

1. If intensity be fixed upon as the standard, no one can define it, so as to tell us what he means. The command requiring us to love with all the heart, if understood as requiring a certain degree of intensity of intention, may mean the highest degree of tension of which our nature is susceptible. Or it may mean the highest possible degree, consistent with our existence in this body; or the highest degree consistent with the most perfect health; or some inconceivable indefinable degree, nobody knows what. It cannot include all, and may and must mean some one of the above-named dogmas. Yet no one would dare to tell us which. Has God given, or does our own reason give us, a standard of moral judgment of which no one can form a conception, or give us a definition?

2. No one could practically apply this standard, if he could define it, as a test of moral action. The reason is obvious. No one, but Omniscience, can possibly know what degree of tensity our nature is capable of; nor precisely what degree is compatible with life, or with the most perfect health. If intensity, then, is the standard by which we are required to determine definitely the character of moral actions, we are in reality required to fix definitely the value of an unknown quantity, to wit: moral action, by a standard of which we are, and of necessity must be, most profoundly ignorant. We are required to find the definite by means of the indefinite; the plain by means of the “palpable obscure.” Has God, or our own reason, placed us in such a predicament as this, in respect to the most momentous of all questions, the determination of our true moral character and deserts?

3. While the standard under consideration is, and must be, unknown to us, it is perpetually varying, and never fixed. The degree of intensity of mental effort of which we are capable at one moment, differs from that which is possible to us at another. The same holds equally of that which is compatible with life and health. Can we believe that “the judge of all the earth” requires us to conform, and holds us responsible for not conforming to a standard located we cannot possibly know where, and which is always movable, and never for a moment remaining fixed?

4. The absurdity of attempting to act in conformity to this principle, in reference to particular duties, will show clearly that it cannot be the standard of moral obligations in any instance. Suppose an individual becomes convinced that it is his duty, that is, that God requires him to walk or travel a given distance, or for a time to compose himself for the purpose of sleeping. Now he must will with all his heart to perform the duty before him. What if he should judge himself bound to will to sleep, for example, and to will it with all possible intensity, or with as great an intensity as consists with his health? How long would it take him to compose himself to sleep in this manner? What if he should with all possible intensity will to walk? What if, when with all sincerity, he had intended to perform, in the best manner, the duty devolved upon him, he should inquire whether the intention possessed the requisite intensity? It would be just as rational to apply this standard in the instances under consideration, as in any other.
