Two Types of EE

Let “weak ethical egoism” be the doctrine that it is wrong to count other people’s interests as having more weight than your own like interests, i.e. acting like a “martyr”. Let “strong ethical egoism” be the doctrine that it is wrong to count other people’s interests as having ANY weight in a case of conflict with your own like interests. Weak EE proceeds from a principle of impartiality in which your interests are not subordinated to the (like) interests of others, and it looks like plain common sense. But strong EE violates such an impartiality principle, and thus is plainly immoral.
