I will explain John Stuart Mill's view on ethics. This includes explaining the "Greatest Happiness Principle", happiness, unhappiness, the quality of pleasure, lying, and the relevance of time from one's perspective. I will then explain how I agree with the principle of rule utilitarianism. I will also examine the conflicting rules objection in rule utilitarianism as well as the negative responsibility objection, giving my response to each. Mill asserts that morality is rooted in utility, otherwise known as the greatest happiness principle. (513) The essence of this principle is that actions are good in proportion to the amount of happiness that results from them and bad in proportion to the amount by which they cause the opposite. (513) In defending this, he asserts that in truth, every action we do, we decide based on this principle.(513) Thus, the best life to live is the one that is most filled with happiness and contains the least misfortune. Happiness is desired pleasure or absence of pain.(513) This definition and the following definition because unhappiness suffers from the real understanding of what pleasure and pain are, the recourse to competent judges and the principles herein. below contribute to this. (513) Unhappiness is the presence of pain or the absence of pleasure. (513) Mill, in response to objections regarding pleasure, claims that some pleasures are better than others. He states that the life of a reasoning, thinking person is superior to that of a human, rather than simply the appetite of an animal. (513) To support this claim, he mentions how those who hold a similar view have previously written that the pleasures of the mind are superior to the body. (513) To support this idea, Mill brings up the idea of ​​competent judges . For someone to be a competent judge, one must... middle of paper ..., and states that very few people need to worry about things at a higher level than friends and family, and that these will have the resources to do so.(516) I have examined Mill's ethical theory of utilitarianism, particularly rule utilitarianism. After examining the negative responsibility objections and conflicting rules, I explained that it is plausible that an individual has a moral responsibility to focus only on their own happiness and that of those around them. I also explained that it is quite trivial to solve the problem of conflicting rules by thinking about rule changes, or even new rules. I have explained Mill's response to the "no time" objection, considering his view on lying. I have given the definitions of happiness, unhappiness, the qualities of pleasure and the role of competent judges in this regard, as well as the principle of greatest happiness..
