| notes)
“ The horse, the dog, the cat, the cow, the ant, the bee, and other animals have some form, however varied, of psycho-physiological activity, some form of mental life, however different in type from that of man. Abnormal psychology discloses to us dissolving views of human consciousness, such as found in the various forms of insanity and in the various manifestations of psychopathic states, presenting conditions of all stages of dissociation and disaggregation of consciousness. Psychic life is by no means uniform, there are many types of consciousness. ”
