What is morally acceptable life?

Philosophers disagree about the nature of a morally acceptable life. A popular position is that living a morally acceptable life means adopting the moral point of view. What is the moral point of view? William Frankena defines it in his Ethics as follows: "one is taking the moral point of view if and only if

* (a) one is making normative judgments about actions, desires, dispositions, intentions, motives, persons, or traits of character;

* (b) one is willing to universalize one's judgments;

* (c) one's reasons for one's judgments consist of facts about what the things judged do to the lives of sentient beings in terms of promoting or distributing nonmoral good and evil; and

* (d) when the judgment is about oneself or one's own actions, one's reasons include such facts about what one's own actions and dispositions do to the lives of other sentient beings as such, if others are affected." So the basic idea is that one is moral if and only if one treats everyone, including oneself, impartially; in other Words, there must be a rational reason for acting differently in ethically similar cases.
