 Kant says that we have a duty to promote the highest good, taken in this sense (5:125). He does not mean, however, to be identifying some new duty that is not derived from the moral law, in addition to all the particular duties we have that are derived from the moral  law.[24]  For example, he is not claiming that in addition to my duties to help others in need, not to commit theft, etc., I also have the additional duty to represent the highest good as the final end of all moral conduct, combined with happiness, and to promote that end. Rather, as we have seen, Kant holds that it is an unavoidable feature of human reasoning, instead of a moral requirement, that we represent all particular duties as leading toward the promotion of the highest good. So the duty to promote the highest good is not a particular duty at all, but the sum of all our duties derived from the moral law – it “does not increase the number of morality’s duties but rather provides these with a special point of reference for the unification of all ends” (6:5). Nor does Kant mean that anyone has a duty to realize or actually bring about the highest good through their own power, although his language sometimes suggests this (5:113, 122). Rather, at least in his later works Kant claims that only the common striving of an entire “ethical community” can actually produce the highest good, and that the duty of individuals is to promote (but not single-handedly produce) this end with all of their strength by doing what the moral law commands (6:97–98,  390–394).[25]
