Abstract

Mulla Sadra has experienced three philosophical journeys: the originality of nature, the originality of existence of gradational oneness and the originality of existence of personal oneness. These three journeys are the main principles of Transcendent Theosophy, and any kind of evolution in them leads to evolutions in minor issues. Due to the systematic connection of the issues, in the issue of the reality of science and various issues related to it, there should be evolutions that are proportional to the three mentioned journeys. According to the first journey of science, the science is from the category of accident and as a result, it is an essential affair, while according to the requirements of the second and third journey, the science has coexistence with existence. This transformation leads to transformation in many minor issues and creates fundamental differences. The issues of the first journey are more influenced by the non-existential view of the realities related to the subject of science, which is referred to as the foundation of qảvm in pre-Sadrai philosophy. In this article, due to the position and opportunity, we will address and analyze some important preliminary issues, which include: the position of discussion, the essential or existential nature of science, being nature or concept of science, the definition of science, the equivocality of names or commonality of meaning of science, being contiguous or analogous of science and the type of attribution proposed in science based on three philosophical journeys.
