In the eyes of Hegel/Sellars/Brandom, Kant is interpreted as having radicalized the distinction between:

  • primary qualities (properties that are truly there)
  • secondary qualities (properties that are due to us).

He challenges us to divide the labor:

  • what features is the world responsible for?
  • what features are we responsible for?
    • E.g. the fact our theories are expressed in German/English

This distinction lives in Sellars as the difference between:

  • the world in the narrow sense
  • the world in the wider sense
    • E.g. which includes norms that are only accessible from a participant’s perspective.

Hegel and Brandom think that, even if it was Kant’s idea, that it is a bad idea (but it’s one that Sellars took from Kant).
