However, I should like to suggest in what direction the answer seems to lie. It would seem that the amount of destructiveness to be found in individuals is proportionate to the amount to which expansiveness of life is curtailed. By this we do not refer to individual frustrations of this or that instinctive desire but to the thwarting of the whole of life, the blockage of spontaneity of the growth and expression of man’s sensuous, emotional, and intellectual capacities.
Testable hypothesis....do regions that have these types of repressions have more "destructiveness" as demonstrated by war violence statistics
