Although at first sight the Speculum contains ‘too little Augustine’ for theologians who are attempting to discover the originality of this thought, it is in fact a revealing anthology. An examination of the criteria used for the selection of Scriptural quotations brings to light an important facet of his mystagogy. Both the exclusion and inclusion criteria demonstrate that Augustine’s intention is to confront his reader with his own imperfections, and this to a much greater degree than is suggested by the (...) understatement of Speculum 108 that the moral guidelines proffered should have an immediate impact. Augustine’s aim in writing the Speculum is to effect a confrontation of the reader with himself, in a first, but permanent step on the way of mystagogy. Scripture serves as a mirror to reflect as detailed and unpolished an image as possible of the person who looks into it; the confrontation must be as violent as possible. (shrink)

In this comment to Kehrer (2014) the relevance of atheistic argumentation in the domain of ethics as an important part of religion is sketched.

This paper deals with the axiomatizability problem for the matrix-based logics RMQ − and RMQ *. We present a Hilbert-style axiom system for RMQ −, and a quasi-axiomatization based on it for RMQ *. We further compare these logics to different well-known modal logics, and assess its status as relevance logics.

This article offers a detailed presentation of three anonymous, unedited sets of questions on Aristotle’s Physics. The commentaries survive in manuscripts in Oxford, Munich and Sint Agatha. A comparison of the lists of quaestiones suggests that there is a close correspondence between the three commentaries, on the one hand, and the ultima lectura of John Buridan’s Quaestiones super octo libros Physicorum, on the other. Judging from the lists of quaestiones, it makes sense to attach the label secundum Buridanum to all (...) three commentaries. However, the texts of the three commentaries differ significantly both from each other and from Buridan’s lecture. To illustrate the differences, in the Appendix I present editions of one question from Book I of the Physics and one question from Book III from each of the three commentaries. The edited questions correspond with Book I q.4 in Buridan’s ultima lectura, “Utrum in omni scientia ex cognitione principiorum, causarum et elementorum contingat alia sci... (shrink)

Historiography of Renaissance philosophy and science has long been characterized by tendencies to minimize the influence of medieval Arabic philosophy and science. According to the standard narrative, the humanists successfully eliminated Arabic writers, along with their Latin scholastic interpreters. Against this background, Dag Nikolaus Hasse calls for a "sober historical approach" in order to "assess the factual influence of Arabic sciences and philosophy in the Renaissance". His narrative is summarized by the title of his impressively erudite and well-documented...
