On the Origin of Human Souls: The Case of Ibn Sina (Avicenna) and Mullah Sadra (Sadraddin Shirazi)

Subscribing to the Platonic concept of the immaterial soul, both Ibn Sina (Avicenna) and Sadraddin Shirazi (Mulla Sadra) accept the idea that human beings possess something beyond the material bodies that represent them in the physical world. However, there are significant differences between their concepts of the soul. One of these differences relates to the origination of the human soul. This paper examines these Muslim philosophers’ approaches to the issue of the soul’s origination. They both consider human souls to be originated, but they differ significantly in terms of the nature of the soul at its origination. Ibn Sina, in line with other Muslim thinkers and defenders of the Platonic soul concept, views it as an immaterial entity upon its coming into existence. However, Mulla Sadra believes that the soul is corporeal at the beginning of its earthly existence. Beyond the issue of the soul’s nature, they also hold different views on how the soul comes into being or is created. Avicenna, as an absolute dualist, believes that the soul is created externally to the body and then added to it, whereas Mulla Sadra holds that it emerges within the body through the evolutionary substantial movement of the latter. Given the variations in these philosophers’ theories on the matter, the paper concludes with the claim that, despite their agreement on the denial of the soul’s pre-existence, there are essential differences between their theories of origination. Ibn Sina appears to be a dualist, while Mulla Sadra leans toward monism.
