The former indicates only dependence of the will or principles of reason in themselves; the second, dependence on principles of reason for the sake of inclination, reason supplying only the practical rules how the requirement of the inclination may he satisfied. In the first case the action interests me; in the second the object of the action (because it is pleasant to me), We have seen in the first section that in an action done from duty we must look not to the interest in the object, but only to that in the action itself, and in its rational principle (viz. the law).] A perfectly good will would therefore be equally subject to objective laws (viz. laws of good), but could not be conceived as OBLIGED thereby to act lawfully, because of itself from its subjective constitution it can only be determined by the conception of good. Therefore no imperatives hold for the Divine will, or in general for a HOLY will; OUGHT is here out of place, because the volition is already of itself necessarily in unison with the law. Therefore imperatives are only formulae to express the relation of objective laws of all volition to the subjective imperfection of the will of this or that rational being, e. g. the human will. Now all IMPERATIVES command either HYPOTHETICALLY or CATEGORICALLY. The former represent the practical necessity of a possible action as means to something else that is willed (or at least which one might possibly will). The categorical imperative would be that which represented an action as necessary of itself without reference to another end, i. e., as objectively necessary. Since every practical law represents a possible action as good, and on this account, for a subject who is practically determinable by reason, necessary, all imperatives are formulae determining an action which is necessary according to the principle of a will good in some respects. If now the action is good only as a means TO SOMETHING ELSE, then the imperative is HYPOTHETICAL; if it is conceived as good IN ITSELF and consequently as being necessarily the principle of a will which of itself conforms to reason, then it is CATEGORICAL. Thus the imperative declares what action possible by me would be good, and presents the practical rule in relation to a will which does not forthwith perform an action simply because it is good, whether because the subject does not always know that it is good, or because, even if it know this, yet its maxims might be opposed to the objective principles of practical reason. Accordingly the hypothetical imperative only says that the action is good for some purpose, POSSIBLE or ACTUAL. In the first case it is a Problematical, in the second an Assertorial practical principle. The categorical imperative which declares an action to be objectively necessary in itself without reference to any purpose, i. e., without any other end, is valid as an Apodictic (practical) principle.
