In this paper we undertake logical deep analyses of Ibn Sīnā’s (c. 980–1037) Flying (or Floating) Man based on Fazlur Rahman’s contribution to Muhammad Sharif’s A History of Islam Philosophy (1963). Next, we show how the Arabic original can contribute to an understanding of the thought experiment beyond the medieval Latin interpretation as after, for example, a recent publication by Dag Nikolaus Hasse. On the basis of the thought experiment analyses and comparison to contemporary postmodern thought experiments we conclude, among other things, that the traditional historical comparison between René Descartes’ Cogito and Ibn Sīnā’s Flying Man is rather unlikely.

Kierkegaard raises many issues in his account of the near sacri­fice of Isaac by his father. Responding to and critiquing Hegelian and Kantian depictions of Abraham, Kierkegaard moves to elevate Abraham into a position as a knight of faith. The Sunnī perception of the incident in the exegetical tradition is far more ethically unequivocal than that of the Latin philosophical tradi­tion. The ubiquitous Sufi theorist, Ibn ʿArabī, however, in a single act of interpretive ingenuity, managed to extirpate the central root of contention raised by the philosophers when he alleges that Abraham was only ever commanded to sacrifice a ram. Despite his abiding commitment to spiritual unveiling (kashf) and his insistence on the personal nature of God, Ibn ʿArabī advo­cates the employment of a Kantian criterion of universal ratio­nality to adjudicate between literal and metaphorical dreams.

In this article, I explore the response of the Ashʿarī theologian Fakhr al-Dīn al-Rāzī (d. 606/1210) to what can be called “the problem of the efficacy of petitionary prayers” (PEPP), namely the effectiveness of making supplications to God that involve a request for something. The key text I examine is al-Rāzī’s highly dense philosophical work al-Maṭālib al-ʿāliya min al-ʿilm al-ilāhī, in which he outlines his core objections to the efficacy of petitionary prayer and then addresses them directly. In section 1, I include a short historiography of specific English books on the topic of supplications (duʿāʾ) and consider the relevance of al-Rāzī’s response to the issue of their efficacy. In section 2, I outline the preliminaries necessary and relevant for understanding the discussion that follows. In section 3, I survey al-Rāzī’s view on personal prayers. In section 4, I exam­ine in detail al-Rāzī’s formulations of the arguments (from the Maṭālib) that constitute PEPP, with parallel discussions in his huge exegetical work Mafātīḥ al-ghayb. In section 5, I lay out al-Rāzī’s responses to PEPP from the Mafātīḥ in more depth, and draw on theological views from his other works to help support his arguments in the Maṭālib. In the conclu­sion, I evaluate al-Rāzī’s responses and the wider implications they have on a Muslim’s relation to and understanding of God.

The concept of nature (Gr. phúsis; Ar. ṭabīʿa) lies at the heart of classical physics. Seemingly small differences about nature can blossom into significant disagreements. The present study offers an exposition of certain neglected passages concerning ṭabīʿa in Ibn Sīnā’s al-Samāʿ al-ṭabīʿī(The Physics of the Healing). The pre­dominant view of ṭabīʿa is that it as an active principle, a concep­tion of nature that radically departs from Aristotle’s account of phúsis in Physics I-II. I dispute this interpretation by investigat­ing two neglected texts in the Physics of the Healing. First, these texts indicate that nature should be associated with matter and form (I, 6) and, second, they argue that failing to account for matter and form makes knowledge of nature incomplete (I, 9).
