Sina's philosophy after Farabi's philosophy, with an accurate search of the views of the ancient Greek scholars, is the basis of Islamic philosophy and one of the foundations of transcendental wisdom. The relation between Sina and Sadra's philosophy is still susceptible to numerous thematic studies. In this research, the views of Ibn Sina and Mulla Sadra have been studied comparatively regarding octet vertices. Among the octet vertices, there is an emphasis on the importance of four subjects: "the definition of philosophy and its importance", "fundamentals and problems of philosophy", "the position of philosophy among other sciences", and "the benefit and place of philosophy ". The views of these two philosophers on the octet vertices of philosophy (as an introduction to philosophy and some of the outside looking into philosophy) are largely linear and compatible, although there are some disagreements. In many cases, Sadra had a viewpoint about Ibn Sina's opinions and was largely criticized and analyzed from Sina's viewpoint. and in spite of Sina's supreme power of philosophy, he has sometimes been forced to use transcendental wisdom because of its conceptual failure; therefore, it can be said that not only at the entrance of philosophy but also in philosophical opinions, if the prophetic power of Sina's philosophy is combined with the conceptual richness of transcendental wisdom, we will have a more powerful and effective philosophical heritage for the contemporary philosophical dialogue.
