What Kant means by treating someone as an end rather than as a means seems to be as follows—as I noticed earlier in using Kant’s moral philosophy to highlight a contrast with emotivism. I may propose a course of action to someone either by offering him reasons for so acting or by trying to influence him in non-rational ways. If I do the former I treat him as a rational will, worthy of the same respect as is due to myself, for in offering him reasons I offer him an impersonal consideration for him to evaluate.
