It actually goes beyond that. We can determine that certain areas of the brain are involved in some types of emotions, some functions such as sight, but we have a long way to go from that to the concept of thought.
The idea of blocking capabilities is also a long way from thought. We know that certain drugs can limit capabilities, but again, that is a long way from thought.
Someday we will likely be able to even find some way of
reading thought.
But there is still the issue of thought itself. There are issues like originality, intuition, discrimination, insight; the difference between genius and mundane. There is the issue of love and art, of beauty and empathy. There is the issue of creativity.
I believe there is still lots for us to learn.
