Meta Ethics
Ethical Naturalism
Background
-
-
-
Ethical statements are treated in the same natural terms that non-ethical statements would (Mathematics and science)
-
-
-
Weaknesses
Hume
-
-
Going from an 'is' statement to an 'ought' statement is fundamentally illogical (Hume's is-ought gap)
E.g. "Humans have canines, therefore you ought to eat meat"
-

-
Intuitionism
G.E. Moore
-
-
Complex ideas
-
E.g. a horse can be broken down into a mammal, quadruped etc.

Pritchard

Therefore not everyone can gain moral truths, intuition is not universal
W.D. Ross

-
Ross's seven prima facie duties: Promise keeping, Reparation, Gratitude, Justice, Beneficence, Self-improvement and Non-malefience

Weaknesses
-
-
-
Nietzsche criticized Moore's yellow patch analogy and argued that one person may see good as one thing whereas another person may see good as another, suggesting the issue of 'ethical colourblindness'
-
Emotivism
-
-
C.L. Stevenson
-
As well as presenting our views through emotions, we are also trying to persuade people to have the same emotive response
Moral statements contain two elements an expression of an attitude based on belief and a persuasive element that seeks to influence others
