Single Idea 13115

[filed under theme 7. Existence / E. Categories / 5. Category Anti-Realism ]

Full Idea

I deny the absolutism of a unique system of ontological categories and the essentialist view of membership in ontological categories as necessary features. ...I regard ontological categories as similar to axioms of formalized theories.

Gist of Idea

Ontological categories are like formal axioms, not unique and with necessary membership

A Reaction

The point is that modern axioms are not fundamental self-evident truths, but an economic set of basic statements from which some system can be derived. There may be no unique set of axioms for a formal system.
