This study focuses on the value of the logical universal in terms of being universal in the philosophy of Avicenna, and al-Ghazālī’s criticisms of Avicenna in the context of the logical universal. A philosophical analysis of al-Ghazālī’s criticisms of Avicenna is made by mentioning how these two thinkers explained the universal and its types, and by revealing the meaning that the universal corresponds to in their thought system. Accordingly, Avicenna talks about three types of universal. The intercourse between these universals is based on an intrinsic relation. The one that determines this kind of relationship and gives a principle has to be an outsider of the universals. According to Avicenna the concept of being determines the meaning of universals and the personal relationship between universal types. In this respect, the rational universal is the reasonable of the universal; the rational universal may be necessary for the logical universal. Therefore, the concept of universal in Avicenna is related to existence. In al-Ghazālī’s thought, we can talk about three types of the universal. He does not name the types of the universal, but distinguishes them by describing them. In his distinction, the concept of partnership is considered in terms of being actual and potential, and being is divided based on these conceptual distinctions. In this respect, we cannot talk about a random distinction between the meaning attributed to universals by Avicenna and by al-Ghazālī but an inherent difference. Based on this separation, al-Ghazālī’s criticisms of Avicenna are also of a essential nature. One of the clearest signs of al-Ghazālī’s criticism of Avicenna lies in the meaning he attributes to the logical universal and the example he gives in the context of the logical universal. al-Ghazālī considers the logical universal as a meaning that does not accept commonality in terms of potential and actual, and attributes the commonality in it to a reason other than what it is. While Avicenna agrees that the meaning that al-Ghazālī’s attributes to the logical universal, saying that it is outside of approval, clearly emphasizes being the subject of conceptualization. al-Ghazālī, on the other hand, ignored this reference of Avicenna and emphasized that Avicenna would accept this, based on the example of “divine/dieu” he gave in the context of the logical universal. However, in Avicenna's philosophical system, it is not possible for the word "divine" to be the subject of imagination, because the “god” is not conceived, but perceived. According to him, the things which are the subjects of imagination potentially contain multiplicity. But the word "god” is not suitable to be the subject of imagination as it is a necessary being. In this respect, it can be analyzed whether al-Ghazālī’s criticisms are austere or nonsense in terms of the five arts (sophistry). The meaning that al-Ghazālī attributed to the logical universal and the examples he gave for this meaning constitute the inherent quality of his criticisms being of the kind of fallacy.
