Cassirer and Reichenbach on the conventionality of geometry

Francesca Biagioli

Short summary

This paper argues that both Cassirer and Reichenbach, when viewed against a neo-Kantian backdrop, present a genuine option where the relativization of the Kantian a priori hinges on the interplay of different levels of constitutivity, specifically concerning the status of geometry in general relativity.

Key points

  • The paper addresses the distinction between the relativization of the Kantian a priori and conventionalism.
  • It focuses on Cassirer's and Reichenbach's views on geometry in general relativity.
  • The core argument is that both philosophers, within a neo-Kantian framework, propose a model where the a priori's relativization depends on different levels of constitutivity.

Abstract

Much of the scholarship on the relativization of the a priori has taken its starting point from the way in which Reichenbach, in The Theory of Relativity and A Priori Knowledge (1920), accounts for the possibility of varying the coordinating principles linking abstract mathematical structures to empirical reality. Such are the principles that Reichenbach called a priori in the sense of constitutive of the objects of experience but no longer valid for all time as Kant thought. However, this poses the problem of distinguishing the relativization of the Kantian a priori from conventionalism. This paper aims to reconsider this issue in the example of Cassirer’s and Reichenbach’s discussions of the status of geometry in general relativity. It will be argued that both Cassirer and Reichenbach, when his work is read against the neo-Kantian background of the debate, offer a genuine option, according to which the relativization of the Kantian a priori depends on the interrelation of different levels of constitutivity
