Meta ethics is a branch of ethics that looks at whether we can know ethical language, such as, 'good', 'bad', 'right', 'wrong'. There are three main theories within meta ethics:
- Inutitionism - a cognitive theory that says we know moral language intuitvely. Main scholars - G.E. Moore, W.D. Ross, Pritchard
- Emotivism - a non-cognitive theory (also known as the boo-hurrah theory) which says we cannot know moral language, and that it is simply an expression of our emotions. Main scholars A.J. Ayer, C.L. Stevenson
- Perscriptivism - a non-cognitive theory which says that moral statements are perscriptive and that when we use them you are stating something which you think everyone should follow. Main scholar R.M. Hare.
