ABSTRACT
IT has been pointed out that, with animals, pleasant experiences tend to be beneficial, while those of a painful nature are liable to prove detrimental. The same rule applies in a general way to the mind of man. Happy emotional tones are disposed to energize and integrate, whereas painful ones, if permitted, will depress and dissociate. While, as we have seen, intensity of feeling is an important factor in influencing tone—very strong emotion of any kind being unpleasant —the most important factor is the variety of emotions stimulated.
