An important part of disagreements with Greek sciences in the world of Islam pertains to their opposition to the field of logic. The discussion of Abū Bishr Mattā (died in 328 AH) with Abū Sa‘īd Sirāfī (died in 368 AH) over logic and grammar is among the first manifestations of such disagreements. The studies focusing on this discussion mainly emphasize Sirāfī’s attempts at proving the superiority of syntax over logic, which, by itself, has resulted in the dominance of a linguistic approach over this debate. As a result, the whole discussion has been reduced to a number of linguistic debates in the mentioned studies. Nevertheless, this debate enjoys some hidden and profound methodological and epistemological aspects which could play a significant role in the correct recognition of the historical context in which it has taken place. In the present paper, the authors not only refer to these almost forgotten methodological and epistemological aspects but also demonstrate their central role through identifying them in the structure and texture of the words of the two scholars. Finally, they connect such aspects to a much vaster historical context.
