Meta-Ethics Flashcards
What are the arguments for: ‘Evolutionary forces have played a large role in shaping the content of human evaluative attitudes.’ Assuming this is true, how should it change how we think about ethics?
- Street’s Darwinian Argument
- Against Street’s Constructivism
What is Street arguing against?
Moral Realism
What is Realism?
That there are at least some normative truths that are true independently of facts about any (real or fictional) person’s (actual or hypothetical) attitudes towards them.
What distinction can we make between Realism and Anti-Realism?
Realism as stance-independent
Anti-Realism as stance-dependent
What is Street’s argument against Realism?
- Natural selection has influenced our normative judgements.
- Either it pushed us to these judgements because theya re true, or it pushed us to them for another reason.
- If not because they are true (and Realism being true), then we get normative scepticism.
- It is highly unlikely that they were naturally selected because those judgements are true.
- So, if the cognitivist wants to avoid normative scepticism, she should not be Realist.
Why would it be highly unlikely that our normative judgements were selected because they are true?
- It would need to be a near miracle.
- This assumes that unless the causal explanation for a belief is that it is true then it is unlikely to be true (Is this appealing?).
What are the different accounts of why we got the normative judgements we do, and which one does Street endorse?
Adaptive Link Account: that we have our normative beliefs because they aid us in passing on our genes (Street).
Truth-Tracking Account: that we have our normative beliefs because they are true.
What is Scanlon’s objection to Street’s Constructivism?
Even if Street is correct about evolutionary pressures, this does not entail Constructivism
How does Street’s argument not entail Constructivism according to Scanlon?
Street assumes that the Adaptive Link Account and the Truth-Tracking Account are incompatible.
- But this needn’t be the case.
- Poison instincts are selected (by EPs) because they help pass on genes.
- Poison instincts are selected because they track truths.
This does not seem to be competing.
What is a potential issue with the Adaptive Link Account and Truth-Tracking Account being compatible?
What if they come to differing conclusions?
- Which one do we stick with?
- It seems as though we would stick with the Adaptive Link Account.
What if tracking moral truths does not help with passing on our genes?
- Whilst having a standard of behaviour has helped us evolutionarily, it doesn’t necessarily seem as though it would impact whether these were true or not.
- The function of morality in our evolutionary progress would seem to be the same.
Why would we prefer the Adaptive Link Account over the Truth Tracking Account?
It is more parsimonious.
- We are committed according to our best science.
- Science does not contain moral truths.
- Therefore we should accept the Adaptive Link Account.
What is Scanlon’s response to the prioritisation of science?
This privilaging is unjustified.
- Why should we have to explain normative truths in terms of science?
- We do not accept the scientific standards for maths, why with morals?
What is the issue with Scanlon’s comparison between morality and maths?
It doesn’t seem as though maths and morality are similar enough.
- According to Scanlon, morality is not purely deductive, maths is.
- We verify them differently
- Maths is descriptive and explanatory, morality is normative.
What is your conclusion for: ‘Evolutionary forces have played a large role in shaping the content of human evaluative attitudes.’ Assuming this is true, how should it change how we think about ethics?
Whilst there are issues with Scanlon’s objection to Street, it doesn’t seem as though it is clear that Street’s dilemma leads to Constructivism.
- Therefore, not much change.
Even if it does entail Constructivism, we can still have moral objectivity, as proposed by Street.
- Therefore, all we would need to rid ourselves of is the idea that moral truths are stance-independent.
Why do we assume that evolution influences our moral decisions?
Because they it seems to have influenced our other decisions and systems of doing things.
Why does Street claim it is a near miracle that the Truth Tracking Account could be correct?
Adaptive Link Account is more parsimonious.
Moral Truths do not seem to cause us to have better success in reproduction.
It does a better job at explaining our moral beliefs, TT seems to fail to give an explanation for why treating our kids well is something so widespread.
Why does Moral Realism need the Truth Tracking account?
Because if our moral cognition’s etiology has no relation to moral truths, our judgements would be unjustified.
