Emotivism - Good cannot be defined; it's just an expression of emotion
A.J. Ayer
Ethical statements don't just express feelings. They are calculated to arouse feeling and to stimulate action.
Ethical statements don't include any facts and therefore have no meaning (no verification through sensory experience)
Created "Boo/Hurrah" theory
Any truth claim only expresses feelings of "boo" or "hurrah" and can only be backed up/made meaningful with empirical fact
C.L. Stevenson
Ethical statements are subjective opinions that influence the views of others
Ethical statements give approval or disapproval rather than just an emotive perspective
Vienna Circle
Emotivism originated from them - they developed logical positivism. This is the idea that truth claims must always be tested by a sense experience (verification)
Presriptivism - Good cannot be defined but can be prescribed
R. M. Hare
You cannot define words such as good/bad but can use them to prescribe behaviour
Every ethical statement should prescribe universal behaviour
The word 'good' has a descriptive meaning but is not a valid statement
Comparison to Emotivism
Where A.J. Ayer says "boo to stealing", Hare would say "boo to stealing" as well as "stealing is wrong because we wouldn't prescribe it for ourselves"
Cognitivism
Ethical naturalism - Good can be applied and applied
Hedonic naturalists
Goodness is something that leads to happiness and avoids pain
F.H. Bradley
Recognise what society needs and wants and then apply yourself to bring the best outcome
Morals come from self-realisation and observation
Your duty is to be good
Theological naturalists
Believe that goodness is linked to the will of God as seen in nature. What is natural is good
Intuitionism - Good cannot be defined but can be applied
H.A. Prichard
Moral obligations are evident because we all recognise what good is
People having different morals just shows how mature your moral development is
Intuitionism isn't something that everyone could use to define goodness
Two types of thinking: reason or intuition. Intuition tells us what is right
G.E. Moore
Naturalistic fallacy = good cannot be defined but can be applied
Intuitionism = adapted form of utilitarianism, suggesting that we can't use senses to say what is good - moral intuition shows us. Example of colour yellow
W.D. Ross
He was a deontologist - effects of actions show us if the action was right/good. Good actions are the Prima Facie duties
Use intuition to choose which Prima Facie duty to follow when they conflict
