Moral realism Flashcards
what do realist theories argue
mind-independent moral properties – such as ‘right’, ‘wrong’, ‘good’, and ‘bad’ – exist.
what is ethical naturalism
says moral properties are natural properties
what is ethical non-naturalism
says moral properties are non-natural properties
most obvious example of a naturalist ethical theory
utilitarianism
what metaethical arg does Mill provide for util
[moral realism - naturalism]
- The only proof that something is desirable is that people desire it
- No proof can be given why the general happiness is desirable other than that each person desires their own happiness
- This desirability is “all the proof the case admits of” that happiness is a good thing
- All our other values (e.g. truth, freedom, dignity) constitute what makes us happy
- In other words, the reason we value these things is because they make us happy
- So, not only is happiness good, it is the only good
alongside util, what is another naturalistic ethocal theory
virtue ethics
why is virtue ethics a naturalistic theory
Aristotle’s discussion of ergon/function can be interpreted as a discussion of natural facts about human beings. We might argue that it is a natural fact that the function of human beings is to use reason – in the same way it is a natural fact that the function of a knife is to cut things. There is nothing spooky or non-natural about claiming that the function of a knife is to cut things and likewise there is nothing spooky or non-natural about claiming that the function of human beings is to use reason.
So, on this reading, ‘good’ reduces to a set of natural facts about function and performing that function well. For example, being courageous is good because being courageous helps humans act correctly according to reason.
problems faced by ethical naturalism
- the naturalistic fallacy
- the is-ought problem
- the verification problem
the naturalistic fallacy [moore]
problems faced by ethical naturalism
the term ‘naturalistic fallacy’ to describe the fallacy (i.e. bad reasoning) of equating goodness with some natural property (such as pleasure or pain). For example, Moore would say it is a fallacy to conclude that drinking beer is good from the fact that drinking beer is pleasurable because they are two completely different kinds of properties – one moral, one natural. Even if pleasure and goodness are closely correlated, it doesn’t and could not follow that they are the same thing. So, Moore would argue that Mill’s proof of utilitarianism is invalid: To conclude that happiness (a natural property) is good (a moral property) commits the naturalistic fallacy
the is-ought prob
problems faced by ethical naturalism
Hume argues that there is a gap between the two kinds of claim: You cannot logically derive ought statements like ‘you ought not torture’ from statements about what is, such as ‘that is an act of torture’. We can argue that this is evidence for non-cognitivism: the reason we cannot derive ‘ought’ statements from ‘is’ statements is because the former type of statement is non-cognitive while the latter is cognitive.
‘is’ statements are factual claims about what is the case
‘ought’ statementsare value judgements about what should be the case
Morality, therefore, is more properly felt than judged of
what is the verification principle
problems faced by ethical naturalism
a statement only has meaning if its either:
1. an analytic truth
2. empirically verifiable
the verification principle applied to moral judgements
Firstly, “murder is wrong” is clearly not an analytic truth. Ayer also argues that “murder is wrong” is not empirically verifiable either – both on the naturalist and non-naturalist interpretations:
naturalism response to the verification principle +ayer’s response to this
Naturalism would argue that we could prove that murder causes pain, anger, etc. However, Ayer argues that this is not the same as proving murder is wrong. Hence, Ayer rejects naturalism: We can empirically verify that murder causes pain, say, but we cannot empirically verify that murder is wrong.
ayer against naturalism
can’t empirically verify the presence of non-natural properties
Ayer also argues that there is no way to empirically verify the presence of non-natural properties. Even if “murder is wrong” did possess the non-natural property of wrongness, how could we ever prove this? It’s not empirically verifiable, nor is it an analytic truth. Hence, Ayer also argues against non-naturalism: The existence of non-natural properties cannot be empirically proven.
what is ethical non-naturalism
Ethical non-naturalism says that moral judgements are beliefs that are intended to be true or false (cognitivism) and that moral properties exist (realism) but are non-natural properties.
