Single Idea 11050

[filed under theme 22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / c. Ethical intuitionism ]

Full Idea

Moore incoherently combines his antinaturalism with the thesis that intrinsic-value properties are logically strongly supervenient on (or explanatorily reducible to) natural facts.

Gist of Idea

Moore's combination of antinaturalism with strong supervenience on the natural is incoherent

A Reaction

I take this to be Moore fighting shy of the strongly Platonist view of values which his arguments all seemed to imply.
