«The mature, productive, rational person will choose a system which permits
him to be mature, productive and rational. The person who has been blocked in
his development must revert to primitive and irrational systems which in turn
prolong and increase his dependence and irrationality. He will remain on the
level which mankind in its best representatives has already overcome thousand
of years ago».
(E. Fromm, Man for himself, 1947).
