Full Idea
For Davidson, mental types are individuated by considerations that are nonscientific, distinctly humanistic, and part normative, so will not coincide with any types that are designated in scientific terms.
Clarification
'Normative' means it creates and follows rules
Gist of Idea
Mind is outside science, because it is humanistic and partly normative

A Reaction
I just don't believe this, mainly because I don't accept that there is a category called 'nonscientific'. All we are saying is that a brain is a hugely complicated object, and we don't properly understand its operations, though we relate to it very well.
