  The ethical egoist might reply that, if predominant egoism is true, ethical egoism may require less deviation from our ordinary actions than any standard moral theory. But fit with motivation is hardly decisive; any normative theory, including ethical egoism, is intended to guide and criticize our choices, rather than simply endorse whatever we do. When I make an imprudent choice, this does not count against ethical egoism, and in favor of a theory recommending imprudence.
