Note 70 — Chapter VI

Professor Hering is not clear here. Vibrations (if I understand his theory rightly) should not be set up by faint stimuli from within. Whence and what are these stimuli? The vibrations within are already existing, and it is they which are the stimuli to action. On having been once set up, they either continue in sufficient force to maintain action, or they die down, and become too weak to cause further action, and perhaps even to be perceived within the mind, until they receive an accession of vibration from without. The only “stimulus from within” that should be able to generate action is that which may follow when a vibration already established in the body runs into another similar vibration already so established. On this consciousness, and even action, might be supposed to follow without the presence of an external stimulus.
