Abstract

Twentieth-century studies on the metaphysics of light (Lichtmetaphysik) have predominantly examined thinkers influenced by Neoplatonic cosmogonies, notably figures such as Robert Grosseteste and Bonaventure. Thomas Aquinas’s discourse on light is often overlooked or dismissed as “merely metaphorical”, in contrast to other approaches recognized as genuinely analogical. This paper explores the reasons behind this interpretation and argues for its inadequacy. We contend, therefore, that Aquinas’s philosophy of light rightfully belongs within the broader intellectual tradition of medieval Lichtmetaphysik, in which light functions as a fundamental ontological principle.
