Formula of Humanity as an End in Itself (FHEI) Formula of Humanity as an End in Itself (FHEI) Formula of Humanity as an End in Itself (FHEI) Always act so as to treat rational beings as ends in themselves, and never merely as means. Respect people. Don t use people. This is Kant s second statement of The Categorical Imperative: i.e. of the single, comprehensive ethical principle; i.e. of the Only Guide You Need! Kant claims the FHEI and FUL are equivalent.
