Ibn Kammūna (d. 1284) is one of the prominent names that present the new structuring that emerged after the classical period studies of Islamic philosophy following the twelfth century. This article deals with his theory of body which has not been discussed before in the academic community. The subject has been handled in connection with the philosophy of nature and metaphysics concerning questions such as how the body exists as a possible essence, how the principles guiding this process are reflected in the field of nature, what the body is, its constituent elements, types, qualities, and additions. Thus, it was determined that in Ibn Kammūna, the first body was the first sphere, the later ones occurred in the process of emanation, and the cause of the body was intellect. Besides, it was established that the body consisting of matter and form is continuous, pointed to itself, and is an infinitely divisible substance. However, it was observed that matter and form, which are constituent elements of the body, were not evaluated under the category of substance. On the other hand, Ibn Kammūna’s approach, which is included in his original works and commentaries, to the main claims of the Peripatetic and Illuminationist traditions about the body has been reviewed. Through the proofs and reasoning made in the details of these claims, it was understood that Ibn Kammûna thought mostly like Ibn Sīnā about the definition and the essence of the body. He occasionally agreed with Suhrawardī about the properties and additions of the body. In this study, it was investigated how the body theory of Ibn Sīnā, who was transformed in Suhrawardī, was shaped in Ibn Kammûna, and whether it has original content in this context. Thus, we aimed to contribute to the field to follow the change, transformation, and transfer process of philosophical accumulation in Islamic thought after these two philosophers, who were the founders of these schools.
