In the theory of collections, not only zero and one, but also the extent of membership of a collection of numbers between zero and one posed. This is the fundamental basis of Fuzzy thinking. The external world is no more white and black; rather, it is grey as well and any member in this grey collection enjoys the numerical value between zero and one. On the other hand, Mulla Sadra’s philosophical system has been formed on the basis of the principality of existence, and the innovation and the highest point in it is the gradation in the orders of truth of existence. In view of the basis of principality of existence, existence is a unique truth that forms all the external identity and text. This unique truth of existence which is common among so many beings and external truths exists in gradation and with orders in the external world. Enjoying gradational thought in transcendental philosophy has beneficial effects in recognizing external beings as plural truths and is, somehow, similar to fuzzy thought. Now the question is whether there is a relationship and affinity between fuzzy thought and the principle of gradation of existence. In seeking to answer this question, the present enquiry has achieved numerous parameters that prove this affinity.
