Ideal utilitarianism states that the only fundamental requirement of morality is to promote a plurality of intrinsic goods. This paper critically evaluates Hastings Rashdall’s arguments for ideal utilitarianism, while comparing them with G. E. Moore’s arguments. Section I outlines Rashdall’s ethical outlook. Section II considers two different arguments that he provides for its theory of rightness. Section III discusses his defence of a pluralist theory of value. Section IV argues that Rashdall makes a lasting contribution to the defence of ideal (...) utilitarianism. (shrink)
