Abstract

In the lively discussion of protophysics of the last ten years, two types of objections have been raised: (a) immanent objections that accept the program of protophysics, but point to mistakes in the execution as presented, and (b) external objections. These can in turn be roughly divided into (lb) philosophical objections (until now only made from the position of modern empiricism) and (b2) physical objections (by means of a confrontation of protophysics and physics). In J. Pfarr, all three types of objections can be found, although his main interest lies in a critique of protophysics from the vantage point of relativistic physics.
