This is particularly clear from the very beginning of the Book on the Science of Metaphysics. For ‘Abd al-Latif, in fact, there are different causes for different kinds of being and different sciences for different causes, but there is one first science leading all the others, for two different reasons. First, as al-Farabi taught, it is able to demonstrate the principles of the other sciences, because it is only this science, which investigates absolute beings and from them it provides an explanation of the principles of the particular sciences, comprised in it and below it. Second, this science includes speculation about the First Principle, which every other thing needs in its own existence. ‘Abd al-Latif claims that this First Principle is the absolute final cause and that the science of this cause is the wisdom (hikma) which precedes all other knowledge (Martini Bonadeo 2010; 2017a).
