Introduction to the Scientific Method and its Factors in Avicenna's Metaphysics

The aim of this paper to open a new approach to the intellectual reconstitution of Avicenna’s scientific thought. In the other word, it is an initial path to detect and deduct Avicenna’s philosophy of science. In this article, after denoting to the place of science in Avicenna’s thought, the philosophy and method of sciences have been discussed. He, about the method, believes in a kind of pluralism. This pluralism must not be regarded as an epistemological confusion or riot and it does not lead to epistemological relativism. Finally, we have tried to elucidate the elements and components of Avicenna’s scientific method such as: the relationship between nature and supernatural, sense of form, the nexus of sciences, teleology, and priority of epistemology general and simple affairs.All together creates a coherent and universal epistemological order in which the science and philosophy will be harmonized.
