An Invitation to Philosophy by Ed L. Miller, McGraw Hill, 4th Ed. One way to approach the topic of morality is to ask whether our actions can be judged right or wrong on the basis of their consequences. The teleological theory suffers from the difficulty that consequences cannot be the sole right-making property of an act. It would seem that intended good consequences are a necessary, but not sufficient condition of moral goodness. On the other hand acts done from duty, which benefit no one and perhaps hurt many, hardly seem good, either.
Hedonists differ as to the type of pleasure they regard as the good.
And they differ as to whose pleasure is to be pursued. It is a combination of doctrines. Inasmuch as it is hedonistic , it seeks pleasure. Because this theory makes it a duty to seek principally one s own interests, it is called ethical egoism. It is to be distinguished from psychological egoism, the theory of human nature which maintains that people by nature pursue their own interests.
