That's one way of defining the word "thinking". But you've
got to concede that, in the age of fMRI and PET scans, this
way of seeing things is not useful anymore.

I guess it all boils down to understand the word "thinking" in
a more broad way. Your way of seeing it seems limited to me, as
it avoids considering all brain activities that *don't* result
in external behavior.

However, there are quite a lot of things happening inside our brains
that don't have externally visible behavior. If you're willing to
dismiss all this activity just to continue using your definition,
then you seem to be dismissing all potential progress that can be
achieved by the neurocognitive way of studying the brain. For instance,
put researcher Isabel Gauthier to look at the pattern of activations
of a fMRI scan and she will tell you if the subject is thinking about
human faces or not (even if the subject remains silent).
