The ArgumentIt was commonly accepted in the middle ages that void within or outside the world is impossible. The paper presents a quite unusual conception of void, which is described in Yeda'aya ha-Penini's commentary on Ibn Rushd's epitome on Aristotle's Physics. According to this conception there is a thin layer of void between the water and the inner surface of the container. Ha-Penini describes two versions of this conception. According to one version this void layer is three-dimensional but thin, according (...) to the other it is two-dimensional. The first part of the paper shows how ha-Penini “corrects” the text of Ibn Rushd, putting into it ideas which were unknown to Ibn Rushd. It is argued that, though the two views are rejected by Ibn Rushd, ha-Penini himself partly accepts (his version of) these views. The second part of the paper argues that ha-Penini could not have found these views in the Arabic-Hebrew tradition, and it seems that he relied on Christian sources. If this is indeed so, the paper presents an example of acquaintance of Hebrew scholars in southern France with Scholastic science in the first half of the fourteenth century. (shrink)

The most striking difference between Christian and Muslim theologies is that while, for Christians, God is a person, Muslims worship an impersonal deity. Despite the importance of this difference for a host of theological issues, it is a difference which has gone largely unnoticed by Christians and Muslims alike. Yet Christians everywhere will affirm that God is a person, while the average Muslim will readily deny this. Theism is often defined by philosophers of religion who work in the Christian tradition (...) in such a manner as to require the belief that God is a person. Thus The Encyclopedia of Philosophy has it that, ‘THEISM signifies belief in one God who is personal, worthy of adoration, and separate from the world but continuously active in it”. John H. Hick admits that, ‘ Theism …is strictly belief in a deity, but is generally used to mean belief in a personal deity”. Richard Swinburne states that a theist is one who believes that there is a God who is a ‘person without a body who is eternal, free, able to do anything, knows everything, is perfectly good, is the proper object of human worship and obedience, the creator and sustainer of the universe”, and J. L. Mackie, while arguing the case of atheism, endorses Swinburne's definition of theism. (shrink)

The concept of tawd (unity of God) is a central issue in Kalm model of discussion and the structure of John Damascene's (d. 750) De Fide Orthodoxa. Pines suggested that it may indicate the profound impact of Christian theology on Mum. Ulrich Rudolph adds two important pieces of evidence to the discussion: He analyzes Abtur al-Samarqandb al-Tawd and the Jacobite Moses bar-Kepha's (d. 903) introduction to his Hexaemeron, and argues that the structural and conceptual affinity between them actually indicates an (...) opposite direction of influence than the one suggested by Pines. According to Rudolph, the similarity of the two treatises shows they were written as an imitation of an older Mub al-Tawd, and second by suggesting an alternative assumption, which will strengthen Pines's theory regarding the development of the Kaltur and bar-Kepha, together with some fragments of earlier Jewish and Christian commentaries on Genesis, will rise the possibility that this model of discussion existed first in the Christian exegetical treatises assigned to Genesis and had already developed before it appeared in the Kalām works.
