In this essay, arguing against the position of
Benjamin Constant,
Des réactions politiques, Kant states that:Hence a lie defined merely as an intentionally untruthful declaration to another man does not require the additional condition that it must do harm to another, as jurists require in their definition (
mendacium est falsiloquium in praeiudicium alterius). For a lie always harms another; if not some human being, then it nevertheless does harm to humanity in general, inasmuch as it vitiates the very source of right []... All practical principles of right must contain rigorous truth... This is because such exceptions would destroy the universality on account of which alone they bear the name of principles. ==Reception==
