Note 110 — Chapter IV · SENSIBILITY.
Reading edition
In consequence of this observation some physiologists have maintained that Feeling or Consciousness never arises in cerebral activity, unless the thalami and the connected tracts are at the same time in action. I go further, and maintain that there is no Consciousness (in the restricted meaning of the term) unless the whole organism is involved. Cerebral or spinal activity will be activity of Sensibility; but this is only the basis of Consciousness.
