ethical egoism

in this blog, I am going to explaining the concepts essay - ethical egoism. Ethical egoism is the prescriptive doctrine that all persons ought to act from their own self-interest. This concept is a term I used to learn philosophy lessons. I think this term is very strange and very difficult to understand. But this concept is very interesting after I understood it. This concept allows me to understand that all things in the world are relative, there is no absolute right or wrong, each person's response to the same thing may be inconsistent with the ideological differences. I chose this concept is because many people know very little about the discipline of philosophy. In many people's mind, philosophy is very esoteric and difficult to understand. And philosophy is very far away from real life.
however, there is a disadvantage in the concept. the ethical egoism is too broad for my classmates and the people who have never touched the knowledge of the area. so I properly will narrow the topic into a specific aspect. like the morality in famine. I looked up through the data analysis. For this concept, two prominent philosophers discussed and analyzed the same issue and put forward different views on how morality should face famine. 
I am going to find some credible and academic research on the topic. I intend to understand this concept by making use of the rich library resources of the school library, inquiring about the developed internet message and looking through the information.
In my opinion, this topic will give readers some idea of philosophy. I will explain the concept separately from two aspects from the two philosophers, and in the process, I will express my opinion on the ethical egoism theory with some easy-to-understand examples of life.
