I got interested in the emotions after studying patients who had lost the ability to emote and feel under certain circumstances. Many of those patients also had major impairments in their ability to make decisions.
Some of us, for better or worse, develop very stable, consistent, and largely predictable machineries of self. But in others, the self machinery is more flexible and more open to unexpected turns.
I continue to be fascinated by the fact that feelings are not just the shady side of reason but that they help us to reach decisions as well.
Why do we have a brain in the first place? Not to write books, articles, or plays; not to do science or play music. Brains develop because they are an expedient way of managing life in a body.
There is no such thing as a disembodied mind. The mind is implanted in the brain, and the brain is implanted in the body.
