Page 548 - ... memory wholly inexplicable as a mere persistence or recurrence of similar impressions. It is this which makes conscious memory a spiritual phenomenon, the explanation of which, as arising out of nervous processes and conditions, is not simply undiscovered in fact, but utterly incapable of approach by the imagination.

Page 518 - The possession of an educated reflex-motor mechanism, under the control of those higher cerebral centres which are most immediately connected with the phenomena of consciousness ; (2) certain motifs in the form of conscious feelings that have a tone of pleasure or pain, and so impel the mind to secure such bodily conditions as will continue or increase the one and discontinue or diminish the other ; (3) ideas of motions and positions of the bodily members, which previous experience has taught us...
