Reviewing and criticizing three theories on the quality of ascription of essential on essence and on each other

There are three theories regarding the quality of ascription of essential on essence and on each other. Most logicians consider that ascription of genus and differentia on the genre and on each other is common technical predication. But according to Allameh Tabatabai, the genus is the same as the ambiguous genre and the differentia is the same the determined genre and the genre is the complete essence without ambiguity and actuality. Contrary to popularity, therefore, he considers ascription of genus and differentia on the genre is primary essential predication but ascription of genus and differentia on each other is common technical predication. But Ayatollah Javadi Amoli, one step ahead of Allameh Tabatabaee, considers that ascription of genus and differentia on the genre and on each other is primary essential predication. In this article, while explaining all three perspectives, we first criticize them and finally we conclude that the famous theory is correct.
