First of all, there are three different types of happiness or pleasure, namely; hedonism which focuses on for the sake of pleasure, Epicureanism which was brought forward by Epicurus who stated that happiness is freedom from bodily pain and mental distress and lastly, utilitarianism which was originated from Bentham and later was explained further by Mill which will be explained further in this essay. Moreover, Kant’s idea of duty will be compared with that of Bentham and Mill’s idea of utilitarianism.
