Note 7 — PART II.

Were morality discoverable by reason, and not by sentiment, 'twould be still more evident that promises could make no alteration upon it. Morality is supposed to consist in relation. Every new imposition of morality, therefore, must arise from some new relation of objects; and consequently the will could not produce immediately any change in morals, but could have that effect only by producing a change upon the objects. But as the moral obligation of a promise is the pure effect of the will, without the least change in any part of the universe, it follows, that promises have no natural obligation.

Should it be said, that this act of the will, being in effect a new object, produces new relations and new duties; I would answer, that this is a pure sophism, which may be detected by a very moderate share of accuracy and exactness. To will a new obligation, is to will a new relation of objects; and therefore, if this new relation of objects were formed by the volition itself, we should, in effect, will the volition, which is plainly absurd and impossible. The will has here no object to which it could tend, but must return upon itself in infinitum. The new obligation depends upon new relations. The new relations depend upon a new volition. The new volition has for object a new obligation, and consequently new relations, and consequently a new volition; which volition, again, has in view a new obligation, relation and volition, without any termination. 'Tis impossible, therefore, we could ever will a new obligation; and consequently 'tis impossible the will could ever accompany a promise, or produce a new obligation of morality.
