In what ways is his hedonistic calculus an attempt to make ethical decision making "scientific"? Does he succeed in developing a "science" of morality? What r some of the drawbacks of using the hedonistic calculus? Give an example of an ethical dilema that might be difficult to solve using the calculus.---------OKAY, NOW 4 THE SECOND QUESTION=it's on DUTY THEORY: Is the categorical imperative a practical guide to morality? Kant argues that sticking to the rule is better than breaking it. Is he right,or can u give an example of a case where perhaps we should make exceptions? What r some of the other weaknesses of Kant's position as a normative moral theory? -------plz people be serious I really need hlp wit this!!!!!!!!!!!!!!!!!
