Thinking About Ethics

Dear Editor: In ‘The Cognitive Gap’, Issue 156, Justin Bartlett questions the position in ethics known as ‘non-cognitivism’ by referring to the Frege-Geach Problem. Geach claims that if saying “Killing is wrong” amounts to nothing more than saying “Boo to killing!”, then a seemingly valid argument turns out to be nonsense. The original valid argument is:

P1: Killing is wrong.

P2: If killing is wrong, then getting your little brother to kill is wrong.

C: Therefore, getting your little brother to kill is wrong.
