1. Intuitionism Just ‘know’ that something is ‘good’
G.E. Moore ( )

2. Starter
Task:
What is a horse?

3. what is yellow?

4. G.E. Moore Principa Ethica.
Moral judgements are based on an infallible knowledge of ‘good’ things.
Make a list of what your intuition tells you are ‘good things’
Task:

5. Moral decision making
‘good’ things
Not 'good' things

6. Moral Debate? ‘good things’ are self evident
Only debate about how to bring these things about.

7. “Good is good”
“If I am asked ‘what is good? my answer is that ‘good is good’, and that is the end of the matter”
“If I asked ‘how is good to be defined?’ my answer is that ‘it cannot be defined’, and that is all I have to say about it.”
G.E. Moore 1903

8. Good is a simple idea Complex ideas Simple ideas Horse – definable
Broken down into smaller ideas
Simple ideas
Can’t be broken down any further
Horse – definable
House - definable
Yellow is yellow
Good is good

9. horse?

10. Describe yellow
yellow?

11. Criticising Naturalism
Their definition of ethical judgement as fact is fallacy
Theological naturalists definition of ‘good’?
Gods' Will
Hedonist naturalists definition of ‘good’?
Pleasure

12. 1st criticism: The ‘Naturalistic Fallacy’
Naturalism confuses a moral judgement (ought) with a non-moral one (is).
Can’t go from an ‘is’ to an ‘ought’
Example:
I observe playing rugby leads to happiness = ‘is’
Therefore playing rugby is good = ‘ought’

13. Pleasure =
Good ?

14. Where are Granny’s savings kept?
God’s will =
Good ?

15. Simple… ‘Good is Good’
“Everything is what it is and not another thing”
Good = good – NOT pleasure.
It is a simple idea, so can’t be broken down into pleasure or God’s will.

16. Quality vs Identity God’s will MAY possess the QUALITY ‘good.’
But it does not have the SAME IDENTITY as ‘good’.
Pleasure MAY possess the QUALITY ‘good’
But it does not the have the SAME IDENTITY as ‘good’.

17. Naturalistic Fallacy The ‘Open Question’ argument
Disproves naturalism
If a statement still leads to an ‘open question’ then the statement is not valid.

18. “George Bush is a brother”
“is George Bush male?”
This is an invalid question – so the original statement is correct

19. But is the war against terror good?
War against terror will lead to saving the lives of others, thereby creating more happiness for the world.
But is the war against terror good?
This is a meaningful question
So the original statement is false.
(creating more happiness, cannot therefore mean ‘good’ or we would not be able to ask the question)

20. Hedonic Naturalistic Fallacy
Bringing back the death penalty would bring about more happiness for society as a whole.
“But is it right to bring back the death penalty?”
Is a meaningful question…
…Therefore ‘more happiness’ and ‘right’ do NOT mean the same thing.

21. Theological Naturalistic Fallacy
Killing a mass murderer just before he embarks on his mission would break a commandment…
“But is it wrong?”
Is meaningful…
…Therefore ‘going against God’s will’ and ‘wrong’ can’t be the same thing.

22. Summary A thing may lead to pleasure… but it is not ‘good’.
A thing may break a commandment… but it is not ‘wrong’

23. 2. Morality is NOT a science
You cannot find natural laws for ethics
‘good’ is recognised intuitively.

24. Moral Intuition They cannot be proved.
Moral intuitions can’t be wrong.

25. The ‘good’ All humans know by intuition that
“The most valuable things… are certain states of consciousness, which may be described as the pleasures of human relationships, and the enjoyment of beautiful objects”

26. Moral actions
‘right’ and ‘good’ are things which bring about the end result of indefinable ‘goodness’.
(ie better relationships with others, and more beautiful objects to enjoy presumably)

27. Criticism 1. Moore doesn’t demonstrate his case.
The indefinable ‘Good’ is never proved.
He claimed that either you agree with his list of indefinable goods, or… you’ve not thought about it enough.
2. Moral argument is merely about which actions bring about these goods.
Most philosophers think this is an unreasonable way to summarize moral debate

28. Intuitionism - Moore
Explain why Moore believes ‘good is indefinable’? (use ‘yellow’, ‘horse’, ‘simple, ‘complex’ in your answer)
Explain the naturalistic fallacy and how Moore uses it to criticise the naturalists? (use ‘is/ought’ idea; examples of the ‘open question’ in your answer)
How else does Moore criticise naturalism?
Write a short definition of ‘good things’ according to Moore.
How would Moore explain how one decides whether an action is right of wrong?
Describe two criticisms of Moore’s view.
