Abstract
This paper proposes a new interpretation of Gadamer’s problematic appropriation of Platonic metaphysics. It argues that Gadamer, attempting to respond to the challenge posed by Heidegger’s interpretation of Platonic metaphysics and of its role in the history of Being (Seinsgeschichte), downplayed the transcendence of Platonic Forms. Gadamer achieves a reconfiguration of this transcendence and its transposition into what I call here a plane of immanence through two hermeneutic gestures: 1) interpreting Forms in light of Greek mathematics and especially in light of the structure of the sum-number; 2) introducing temporality and historicity in the Medieval doctrine of transcendentals by giving priority to the Beautiful over the Good. I contend that, Platonically speaking, this amounts to the rejection of νοήσις in favor of διάνοια, and that this raises issues concerning the problem of finitude and the potential limits of linguisticality (Sprachlichkeit).
