I recently answered this question on the ethical duty to help educate others, where I wrote:
I feel like if a person increases "happiness" more in his life then he decreases the "happiness" then a person is moral. If a person helps only 1 person in his life but doesn't harm anybody then he is moral. He is not required to help everybody he can. He doesn't need to send aid to third world countries nor is it his duty to educate people that are of lower intelligence or knowledge. He definitely may and that will make his behavior even better but it doesn't mean that if they don't they are immoral. In such philosophy it's not a person's duty to help others.
After answering the question, I realized I do not know what I would call the moral philosophy which I follow. I wonder if there are any similar philosophies which follow similar moral code. Unlike utilitarianism I do not think everyone has a duty to maximize happiness. Simply, people have a duty to increase happiness more then they decrease it in order to remain moral.
Is this still a form of utilitarianism? Is there any other philosophy that agrees with my statement?
Update: I forgot to mention that I also dont believe that ones morality should definitely be judged by their actions but by their moral code. (so if you kill someone by mistake it doesnt mean you are immoral) I dont know how it is with Utilitarianism.
