  We shall limit ourselves here to a few examples drawn from the partial edition of this commentary published by H. Ziai and A. Alwishah, which covers part two of al-Talwīhāt and whose subject is natural science or physics. Ibn Kammuna describes in one place quotes approvingly Suhrawardi’s account of how greatly people differ in this respect: “People differ with regard to ḥads. There are the doltish, who have never had any success in thinking; and there are those with powerful ḥads. Many of the latter exceed others in quantity and quality; but there is no limit, at which one must perforce stop. It is possible for there to be someone who perceives by means of ḥads most of the intelligibles in a short time and without a teacher; and there is a [type of] soul called ‘holy’ whose capacity is as powerful as that of the prophets” (Ziai &amp; Alwishah 2003, 456).
