Avicenna, with the theory of the spiritual origination of the soul along with the body, was able to overcome some of the problems of the Aristotelian method in a step forward. But the question is, how did this famous philosopher and medical doctor express this matter in his philosophical natural sciences and what natural basis did he use? Another question is, if Avicenna’s explanation of soul origination in the nature of the body is consistence with his explanation of the soul origination in the body in his mind philosophy? In order to answer this question, the quality of life, nutrition and growth from the beginning of the formation of the sperm in the embryo is investigated in the Avicenna’s philosophical natural sciences. He said that the sperm becomes ready to receive the life-giving heavenly potency by using heavenly heat, and the soul potencies take responsible of planning, maintaining and growing the embryo's body through the vapor spirit. Then, after the formation of the heart in the embryo, the soul belongs to the heart and will take over the leadership of the whole body. In the second step, this article presents a solution to compatible these two explanations by using a different interpretation of Avicenna's expressions.

The quality of soul’s origination in body is one of the most important issues in philosophy of mind. The theory of soul’s spiritual origination along with body, has been assigned to Avicenna in the official statement. Therefore, which soul will manage this imperfect body? Scholars such as Fakhr Razi, Mulla Sadra, and neo-Sadraian commentators such as Hassanzadeh Amoli believe that, according to Avicenna, father's soul was in charge of body at that stage.This study, by looking at this theory again, by considering important role of Avicenna’s body knowledge and using the same expressions quoted by these sages, in the Book of Healing, wants to prove how the origin of the embryo’s soul arises in the sperm. Also, in the justification of the quality of growth in humans, according to the Avicenna, the gradual movement called the concept of evolution has been used, which can be explained only by evolution in substance in the stages of growth. Using these principles, this article tries to prove the hypothesis of origination and substantial evolution in the embryo's soul and body, so that with this reading of the soul’s origination, to solve the problems affecting the way the embryo is managed by.
