 Kant describes the will as operating on the basis of subjective volitional principles he calls “maxims”. Hence, morality and other rational requirements are, for the most part, demands that apply to the maxims that we act on. . The form of a maxim is “I will A in C in order to realize or produce E” where “A” is some act type, “C” is some type of circumstance, and “E” is some type of end to be realized or achieved by A in C. Since this is a principle stating only what some agent wills, it is subjective. (A principle that governs any rational will is an objective principle of volition, which Kant refers to as a practical law). For anything to count as human willing, it must be based on a maxim to pursue some end through some means. Hence, in employing a maxim, any human willing already embodies the form of means-end reasoning that calls for evaluation in terms of hypothetical imperatives. To that extent at least, then, anything dignified as human willing is subject to rational requirements.
