Single Idea 21408

[catalogued under 1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual]

Full Idea

A philosophy of any subject (a system of rational knowledge from concepts) requires a system of pure rational concepts independent of any conditions of intuition, that is, a metaphysics.

Clarification

'Intuition' is here (roughly) experience

Gist of Idea

For any subject, its system of non-experiential concepts needs a metaphysics

A Reaction

'Pure rational concepts' must be a priori, and (in Kant's case) transcendental - i.e. discovered from the study of presuppositions. Does this actually say that the philosophies of science, biology, psychology, economics etc each needs a metaphysics?
