 But that is not the only way of taking the general notion of impartiality and making it more specific. The general idea, as stated earlier, is that moral thinking, unlike prudential thinking, is not self-centered. One can make this idea more concrete by taking it to mean that there is a single set of rules or norms that apply equally to all human beings, and so the standard by which one answers the question, “what should I do in this situation?” is the standard by which one answers the question, “what should anyone do in this situation?” Someone whose practical reasoning is guided by this condition is abiding by an ideal of impartiality. He makes no special exceptions for himself or his friends.
