Problems with utilitarianism include:
A.
Are there really no actions that are intrinsically wrong? Can utilitarianism recognize the existence of rights?
B.
How do we justify the claim that we should aim to produce the greatest happiness of the greatest number? How do we know in advance what the consequences of our actions will be?
C.
Must we always act to produce the greatest happiness of the greatest number? What is happiness and how do we measure it?
D.
Whose happiness must be counted? Can a utilitarian account for personal integrity?
