Mindmelding: two brains, one consciousness?

Mindmelding: two brains, one consciousness?: "Have you ever wondered if it is really possible for others to know what you are thinking? Our brains seem to allow both “internal” points of view, and “external” ones.  As individuals, we know them from the inside as we experience our thoughts, perceptions, and emotions. Scientists, on the other hand, only know our brains from the outside, as they employ brain imaging, EEG, or other types of techniques. This appears to imply that scientists are cut off from ever studying our brains from the internal point of view.  But if this is right, it has huge consequences for the way we think of our minds. If our thoughts and feelings exist in a realm that science can never touch, then perhaps they aren’t really physical?  And if this is right, it would lend great support to the ancient theory of dualism, according to which the mind and the brain (along with the rest of the body) belong to two different metaphysical categories, the mental and the physical."
