On defining the brain

Depending on how you define the brain, I have no trouble with the idea that the mind is the brain. But the brain, or parts of it, have to have characteristics that are atypical of ordinary matter, otherwise thinking would not be possible. It would have to have intentionality as a property at the most fundamental level, purpose at the basic level, subjectivity at the basic level, and normativity at the basic level. Good luck getting that by the skyhook police.
