A compromised constitution of intersubjectivity from the perspective of a Weylian schema

Abstract

Weyl proposed a schema for symbolic construction of scientific representation starting from subjective immediate experience, and moving toward the objective ordered manifolds of possibilities due to "rational motives" of comprehending the world in "the 'truly objective', exact, non-qualitative" way. Weyl's purely infinitesimal geometry may be viewed as an application of the schema.Weyl himself as well as various researchers have discussed the introduction of a local coordinate system as an effort to bridge the chasm between the intuitive and the mathematical continuum for this schema. I argue that the introduction of a local coordinate system only explained the "exact, non-qualitative" aspect of the "rational motives", and there is also a problem of how the intersubjective constitution is possible. The latter was not explicitly explained by Weyl, and corresponds to the "truly objective" aspect of "rational motives". I argue that, a comprised intersubjective constitution could be achieved by a strategy of introducing an additional structure to starting points for theoretical constructions. The strategy might also provide an explanation for gauge invariance in Weyl's unified field theory.
