Gundissalinus’s Application of al-Fārābī’s Metaphysical Programme. A Case of Epistemological Transfer

This study deals with Dominicus Gundissalinus’s discussion on metaphysics as philosophical discipline. Gundissalinus’s translation and re-elaboration of al-Fārābī’s Iḥṣā’ al-ʿulūm furnish him, in the De scientiis, a specific and detailed procedure for metaphysical analysis articulated in two different stages, an ascending and a descending one. This very same procedure is presented by Gundissalinus also in his De divisione philosophiae, where the increased number of sources –in particular, Avicenna– does not prevent Gundissalinus to quote the entire passage on the methods of metaphysical science from the Iḥṣā’ al-ʿulūm, with some slight changes in his Latin translation. The analytical procedure herein proposed becomes an effective ‘metaphysical programme’ with regards to Gundissalinus’s onto-cosmological writing, the De processione mundi. The comparative analysis of this treatise with the procedure received by al-Fārābī shows Gundissalinus’s effort to follow and apply this metaphysical programme to his own reflection, in a whole different context from al-Fārābī’s and presenting doctrines quite opposed to the theoretical ground on which al-Fārābī’s epistemology is based, like ibn Gabirol’s universal hylomorphism. Nevertheless, thanks to the application of the ‘metaphysical programme’, one can effectively claim that Gundissalinus’s metaphysics is, at least in the author’s intentions, a well-defined metaphysical system. In appendix to this article the three Latin versions of al-Fārābī’s discussion on metaphysics are reported, e.g., Gundissalinus’s quotations in De scientiis and De divisione philosophiae, and Gerard of Cremona’s translation in his De scientiis.
