The idea of ​​ordering the system of existence can be traced back to the Greek philosophers; In philosophy, as well as in popular mysticism among Muslims, the theory of "the system of existence has levels" is a theory that, despite its different interpretations and explanations, has been accepted and is considered one of the fundamental issues. Although objectivity in some of those levels - such as the world of matter - is accepted by Muslim philosophers, but which of the two approaches, objective and subjective, is more justified in relation to the world of example, is a question that still requires an answer.The approach of transcendental wisdom and especially Mulla Sadra is purely objective towards the world of matter, towards the world of example, purely subjective, and towards the world of reason, it is an objective and subjective approach; This research tries to analyze the reasons that Mulla Sadra has put forward to prove the world of separate reason, to criticize the reasons that defend his purely subjective approach to the world of example, and to show that by sticking to reasons such as the rule of possibility, it is possible to prove the existence of the world of separate example. He also considered it justified and had an objective approach towards the world of example.
