  • The Waṭwāṭ–al-Īlāqī Correspondence on Modal Conversion

    Hamed Arezaei, Mojtaba Emranipour et al.ARTICLEOriens2026

    This article presents and analyzes a twelfth-century philosophical correspondence between Rashīd al-Dīn Waṭwāṭ and Sharaf al-Zamān al-Īlāqī concerning Avicennan modal logic. Their debate focuses specifically on the conversion ( ʿaks mustawī ) of the universal negative conventional proposition. By examining their exchanges, the paper highlights the intellectual friction and terminological ambiguities prevalent in post-Avicennan logic. The correspo…

  • Burhān al-dīn Nasafī as the Author of Al-Manṭiq al-kabīr (MS Aḥmad iii, no. 3401)

    Asadollah FallahiARTICLEHistory and Philosophy of Logic2024

    Recently, in ‘An inquiry on Fakhr al-Dīn Rāzī’s authorship of Al-manṭiq al-kabι ̄r (MS Aḥmad iii, no. 3401)’, we refuted the quite common view among historians of Arabic logic as to attribute Al-manṭiq al-kabι ̄r (Major [book on] logic) to Fakhr al-dīn Rāzī; however, in that paper, we could not identify the real author of the book. In this paper, we try to show that Al-manṭiq al-kabι ̄r was written by Burhān al-dīn Nasafī (1203–1288), who authore…

  • Early Arabic logicians on the contraposition of the particular affirmative

    Asadollah FallahiARTICLEBritish Journal for the History…2023

    This paper is a narrative of the fate of I-contraposition in the early Arabic logic. I will study Avicenna’s, al-Suhrawardī’s, al-Rāzī’s, al-Kashshī’s, and al-Khūnajī’s views on this rule. Although Avicenna explicitly acknowledged I-contraposition in a brief note, and in an apparently Meinongian language, the other four figures found I-contraposition problematic and listed some counterexamples to it. Nonetheless, they all attempted to justify Avi…

  • An Inquiry on Fakhr al-Dīn Rāzī’s Authorship of Al-Manṭiq al-kabīr (MS Aḥmad iii, no. 3401)

    Asadollah FallahiARTICLEHistory and Philosophy of Logic2021

    It is quite common among historians of Arabic logic to attribute MS Aḥmad iii, no. 3401, entitled Al-manṭiq al-kabīr (Major [book on] logic), to Fakhr al-Dīn Rāzī. This view is expressed explicitly and forcefully by Franziska Knobel (2015) and Turgut Akyüz and Elmin Aliyev (2020). In this paper, we try to refute this attribution through textual analysis, thereby exposing new evidence to the contrary. We show that the text has several references t…
