Another (much longer) quote:

Specifically, I am a moral realist. Furthermore, I reject the claim that there is some hard distinction between 'is' and 'ought'. Loyal readers should be familiar with my claim that we should focus instead on the distinction between 'is' and 'is not'. Morality either belongs in the realm of 'is' (somehow), or it belongs in the realm of 'is not'.

However, this does not tell us where to find morality in the realm of 'is'. In past conferences, I have found that the neural ethicists were looking in the wrong spot.

Let me illustrate with an example. A researcher takes a hoard of subjects and performs brain scans on them while they think about planets and stars and take astronomy tests. He may learn a lot of interesting things, However, it would be a mistake to call this researcher an astronomer. Studying thoughts about stars and studying stars is not the same thing.

Neural ethicists seem to be unaware of this distinction. They study the brain while the subject thinks about moral concepts or works through some moral problem or puts down an answer on some moral test, and they think they are studying morality. They are not. They are studying beliefs and other attitudes on morality.
