 the other condition of mind known to us, we find that 

 it occupies a position between the ordinary waking 

 state of consciousness and the abnormal conditions of 

 hypnosis and hysteria, which is rather daringly called 

 double personality, t 



Many things, it is true, in our waking life suggest 

 a divided consciousness, but the cleft is not so deep 

 as in the abnormal condition. I am not now speaking

 physiological stimuli that continually set our brains
