The nature of the human mind is addressed from a neurological viewpoin
t. First from reported observations on subjects born blind with congen
ital cataract. who acquired vision after surgery. the concept of the p
rimacy of somatosensation is developed. Therefrom some principles of t
he organization of higher sensory functions in the dominant parietal.
occipital and temporal lobes are deduced. Sentience is traced to somat
osensation. Some characteristics of the mind and of thinking are descr
ibed. The non-existence ot' the unconscious is inferred. The question
of free will is approached. Using neurological experience it is demons
trated that a good case for operation of a free will is difficult to e
stablish. Positing the absence of a free will may be beneficial in the
analysis and management of behavior. Finally the opportunity to study
the nature and mechanism of the emotions in clinical neurology is out
lined.
