In 'Self Comes to Mind' I pay a lot of attention to simple creatures without brains or minds, because those 'cartooned abstractions of who we are' operate on precisely the same principles that we do.

I believe that it is made out of the same cloth of mind, but it is an add-on, it was something that was specialized to create what we call the self. And it exists for very special purposes and it has very special, and I think by and large good consequences, although not only good consequences.

So, you can define emotions very simply as the process of perceiving what is going on in the organs when you are in the throws of an emotion, and that is achieved by a collection of structures, some of which are in the brain stem, and some of which are in the cerebral cortex, namely the insular cortex, which I like to mention not because I think it's the most important, it's not.

How can you have this reference point, this stability, that is required to maintain the continuity of selves day after day?

There is no such thing as a disembodied mind. The mind is implanted in the brain, and the brain is implanted in the body.

Leaving out appraisal also would render the biological description of the phenomena of emotion vulnerable to the caricature that emotions without an appraisal phase are meaningless events. It would be more difficult to see how beautiful and amazingly intelligent emotions can be, and how powerfully they can solve problems for us.

We remove ourselves from the experience itself to a surrogate of the experience, which is whatever measure you take from the brain, be it the electroencephalogram or magnet encephalography or say functional magnetic resonance. So it's pretty tough to make those comparisons.
