Abstract: The study on the origin of justice proposed and developed by western thinkers has self-evidence effect. The way of the argumentation is full of subjective imagination and lack of objectivity. Therefore, it is necessary to jump out of the circle of the circular argument of the humanities and social sciences, introduce theories and methods of natural sciences in a timely manner, and explain the origin of justice by using the stress theory. According to this paper, the stress theory put forward by Hans Selye, a Canadian pathologist, provides a new way to explain the origin of justice. The process of justice is actually a process of stress response. The irrational distribution of resources is the source of stress, the resistance and compromise are the behavior of stress response, and the emergence of justice can be regarded as the result of stress reaction. That’s to say, these are the condition, path and symbol of the origin of justice. As an attempt, the study of the origin of justice from the perspective of stress theory can be regarded as a new development of justice theory in the contemporary era. It is still worth looking forward to that whether there is a more scientific and appropriate theory applicable to the study of the origin of justice.
