T h e reader who has followed our discussion and explana­ tion of mental processes will have noted the fundamental part played by experience. The normal human organism includes an elaborate nervous system with either actual or potential neuron patterns capable of responding to all the important stimuli and directing all the necessary ac­ tions of life. But even those inborn neuron patterns can­ not function without being set into activity by an ap­ propriate stimulus. Indeed, there seems good reason to believe, that if the stimulus is never presented, these specific neuron patterns either degenerate or become so subordinate to other patterns that are exercised, that for all practical purposes it is as tho such patterns did not exist.
