In estimating what is good or evil in itself, as distinguished from what can be so called only relatively, the following points are to be considered. Either a rational principle is already conceived, as of itself the determining principle of the will, without regard to possible objects of desire (and therefore by the more legislative form of the maxim), and in that case that principle is a practical a priori law, and pure reason is supposed to be practical of itself. The law in that case determines the will directly; the action conformed to it is good in itself; a will whose maxim always conforms to this law is good absolutely in every respect and is the supreme condition of all good. Or the maxim of the will is consequent on a determining principle of desire which presupposes an object of pleasure or pain, something therefore that pleases or displeases, and the maxim of reason that we should pursue the former and avoid the latter determines our actions as good relatively to our inclination, that is, good indirectly, (i.e., relatively to a different end to which they are means), and in that case these maxims can never be called laws, but may be called rational practical precepts. The end itself, the pleasure that we seek, is in the latter case not a good but a welfare; not a concept of reason, but an empirical concept of an object of sensation; but the use of the means thereto, that is, the action, is nevertheless called good (because rational deliberation is required for it), not however, good absolutely, but only relatively to our sensuous nature, with regard to its feelings of pleasure and displeasure; but the will whose maxim is affected thereby is not a pure will; this is directed only to that in which pure reason by itself can be practical.
