Lecture 5 Internalism, Externalism, and the Belief-Desire Theory 1.
Moral judgements can t be true or false.
Roughly speaking, internalism is the view that there is a conceptual or internal connection between moral considerations and motives or reasons for action. Externalism is just the denial of internalism. Motivation and Probability One thought behind the denial of internalism might be this. Someone only counts as being motivated if the likelihood of her acting is higher with the supposed motivation than without it. And then it might seem that one could judge that one ought to A without the probability of one s A -ing being raised at all.
