Beliefs and desires aren't real; they are prediction techniques [Dennett]
|
|
Full Idea:
Intentional systems don't really have beliefs and desires, but one can explain and predict their behaviour by ascribing beliefs and desires to them. This strategy is pragmatic, not right or wrong.
|
|
From:
Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.7?)
|
|
A reaction:
If the ascription of beliefs and desires explains behaviour, then that is good grounds for thinking they might be real features of the brain, and even if that is not so, they are real enough as abstractions from brain events, like the 'economic climate'.

The 'error theory' of morals says there is no moral knowledge, because there are no moral facts [Mackie, by Engel]
|
|
Full Idea:
Mackie's 'error theory' of ethics says that if a fact is something that corresponds to a true proposition, there are actually no moral facts, hence no knowledge of what moral statements are about.
|
|
From:
report of J.L. Mackie (Ethics: Inventing Right and Wrong [1977]) by Pascal Engel - Truth §4.2
|
|
A reaction:
Personally I am inclined to think that there are moral facts (about what nature shows us constitutes a good human being), based on virtue theory. Mackie is a good warning, though, against making excessive claims. You end up like a bad scientist.

You can't form moral rules without an end, which needs feelings and a moral sense [Hutcheson]
|
|
Full Idea:
What rule of actions can be formed, without relation to some end proposed? Or what end can be proposed, without presupposing instincts, desires, affections, or a moral sense, it will not be easy to explain.
|
|
From:
Francis Hutcheson (Treatise 4: The Moral Sense [1728], §IV)
|
|
A reaction:
We have no reason to think that 'instincts, desires and affections' will give us the remotest guidance on how to behave morally well (though we would expect them to aid our survival). How could a moral sense give a reason, without spotting a rule?

We are asked to follow God's ends because he is our benefactor, but why must we do that? [Hutcheson]
|
|
Full Idea:
The reasons assigned for actions are such as 'It is the end proposed by the Deity'. But why do we approve concurring with the divine ends? The reason is given 'He is our benefactor', but then, for what reason do we approve concurrence with a benefactor?
|
|
From:
Francis Hutcheson (Treatise 4: The Moral Sense [1728], §I)
|
|
A reaction:
Characteristic of what MacIntyre calls the 'Enlightenment Project', which is the application of Cartesian scepticism to proving the foundations of morals. Proof beyond proof is continually demanded. If you could meet God, you would obey without question.
