The fact is that no abstruse complicated psychological analysis was necessary here or in most cases. A man is "jarred" from light-hearted health to a grim discouraged state. This discouragement brings with it sleeplessness and loss of appetite, and there gradually develops a series of habits which lower endurance and energy. The habit elements in this condition are not enough recognized, and also the fact that most of the disability is physical in its development though psychological at the start. That is, A. had a severe emotional reaction to a horrible experience; this brought about insomnia and disordered nutrition, and these, by lowering the endurance and ability, brought to being a vicious circle of fatigue and depression, in which fatigue caused depression and depression increased fatigue. The treatment must be directed at first to the physical factors, and with these conquered the acquired forms of anhedonia usually yield readily. It would be interesting to consider other types related to the anhedonic personality. The complainer, the whiner, the nag, all these are basically people who are hard to satisfy. The artistic temperament (found rather frequently in the non-artistic) is hyperesthetic, uncontrolled, irritably egoistic and demands homage and service from others which exceeds the merit of the individual; in other words, there is added to the anhedonic element an unreasonableness that is peculiarly exasperating. I pass these interesting people by and turn to the opposite of the anhedonic group, the group that is hearty in tastes and appetites, easily pleased as a rule and often crude in their relish of life. There are two main divisions of these hearty simple people,--those who are untrained and relatively uneducated, and whose simplicity may disappear under cultivation, and another type--cultivated, educated, wise--who still retain unspoiled appetite and hearty enjoyment. Briefly let me introduce Dr. O., an athlete in his youth and always a lover of the great outdoors.
