Abstract

In this paper I analyse the process of formation of medieval classical metaphysics, that as science of being qua being, that seeks to establish the proof for the existence of God. My focus is the beginning of medieval philosophy and its development until 13^th century until classical theistic metaphysical systems are formed. The central figure of this long process of development is Avicenna whose ideas were fundamental for the foundation of metaphysical science both in Islamic and Christian civilization. It is Avicenna who, by following Aristotelian tradition, set the standard and defined the subject matter and the goal of metaphysics. Through this analysis the paper aims to highlight one aspect of the interconnection between Christian and Islamic medieval philosophy which reflects in their approach to what they considered as the most important thing in human existence: the knowledge of God.

Key words: medieval philosophy, classical metaphysics, existence of God, Platonic-Aristotelian tradition, Christian civilization, Islamic civilization.
