Sheikh Ishraq, Fakhruddin Razi and Mulla Sadra on the Nature of Assent

One of the major issues in logic, philosophy and epistemology is that of knowledge and its parts. Since far away, in Islamic philosophy and logic, knowledge has been divided into two forms of concept and assent. But in this regard, the truth of the assent, especially since the time of the Sheikh Ishraq, has been considered seriously. According to him, assent is not knowledge, although it can belong to knowledge; while for philosophers, it is considered as knowledge truly. On the other hand, Fakhruddin Razi, while acknowledging assent as a form of knowledge, considers it to be composed of concepts and judgments, while other philosophers have viewed it to be simple not composed. Of course, here it is important to note that if the conception and assent are types of knowledge, they must be separated from each other by a bond. So, how can one acknowledge that assent is simple knowledge? Therefore, Mulla Sadra, with a very detailed analysis, sees assent as a simple fact at the same time as an analytic compound. In Mulla Sadra's view, assent is a concept just the same as judgment and the judgment in assent as a species, fasl, and the concept itself is its genus. Therefore, a judgment like every species is the same as the mode of its genus. In terms of Mulla Sadra, the philosophers` views on the simplicity of assent and conditionality of concept for it return to his view.
