Single Idea 22151

[filed under theme 22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / a. Idealistic ethics ]

Full Idea

Moore's Open Question argument led, however unintentionally, to the rise of anti-realism in meta-ethics (which leads to distinguishing values from facts).

Gist of Idea

The Open Question argument leads to anti-realism and the fact-value distinction

comment on G.E. Moore (Principia Ethica [1903]) by Stephen Boulter - Why Medieval Philosophy Matters 4

A Reaction

I presume that Moore proves that the Good is not natural, and after that no one knows what it is, so it seems to be arbitrary or non-existent (rather than the platonic fact that Moore had hoped for). I vote for naturalistic ethics.
