My memory of hospitals I have known, and my mental picture of yours made up from piecing together the memories of various ones, the recollection of the feelings I had in them, etc. (intellect). What you already know. Speculation (intellect), the speculation based on my knowledge of other schools (memory which is intellect). A desire (emotion) that all nurses should know psychology. Child calling on street. Recognition of sound (intellect) and pleasant perception of his voice (emotion). Desire to throw work aside and go for a tramp on this gorgeous day. Emotion, restrained by stronger emotion of interest in work at hand, and _intellect_, which tells me that this is a work hour--and _will_, which orders me to pay attention to duties at hand. So all the phenomena of mental life are included in feelings, thoughts, and volitions which accompany every minute of my waking life, and probably invade secretly every second of my sleeping life. The conditions of mental life--what are they? 1. In man and the higher animals the central nervous system, which, anatomy teaches us, consists of the brain and spinal cord. (In the lowest forms of animal life, a diffused nervous system located throughout the protoplasm.) 2. An external world. 3. A peripheral nervous system connecting the central nervous system with the outside world. 4. The sympathetic nervous system, provided to assure automatic workings of the vital functions of the body. These organs of the mind will be discussed in a later chapter. CHAPTER II CONSCIOUSNESS We took a glimpse at random into the mental life of an adult consciousness, and found it very complicated, constantly changing. We found it packed with shifting material, which, on the surface, seemed to bear very little relation. We found reason, feeling, and will all interacting. We found nothing to indicate that a consciousness as simple as mere _awareness_ might exist. We believe there might be such in the newborn babe, perhaps even in the baby a month old; but can we prove it? Let us look within again and see if there are not times of mere, bare consciousness in our own experience that give us the proof we need.
