Sound Mind - John Haslam - Bog

This is a science book. This circumstance would render it probable that the larger branch of the nerve becomes itself impregnated with the sensation it transmits: indeed it is a continuation of the same substance, from its sentient extremity to its sensorial insertion. This intimate union of nerve and brain may be further illustrated: it has been already noticed, that a morbid state of the organs of sense will convey inaccurate perceptions; and it is equally certain, that disease of the brain, will excite phantasms, which appear as realities to the sensitive organs. As consciousness is implied, in order to constitute the act of perception, it is of some importance to investigate the nature and meaning of this term. The consciousness of having experienced a perception by any of the senses would be an act of memory: consciousness, therefore, applies to the past; and it also accompanies our prediction of the future.
