One of the deep-rooted problems in ethics is the nature of morality. In general this debate was purely philosophical in the history of ethics. But, recently, there have been attempts to solve the problems through the aid of science. Since E. O. Wilson showed the will to integrate ethics into sociobiology, this study makes interesting progresses. The scholar who played the leading role for this kind of study was M. Ruse. He was a philosopher who tried to fulfill Wilson's will. But as he was not an ethical specialist, his works faced many issues. Since then, many scholars tried to make better ethical theories by uniting merits and demerits of Ruse's theory. Through these efforts, the explanation for the mechanism of moral judgment is becoming more sophisticated all the time. Also, the discussion of field which he was focused on is becoming popular. In this essay, I tried to signpost a way to solve the meta ethical arguments which concern the nature of morality with these theories. Nevertheless, due to the lack of time, I could not deal with the topic sufficiently. This essay is a kind of a tentative plan, thus, many parts of the arguments should be further reinforced.
