“If man were infinitely malleable, there would have been nor revolutions; there would have been no change because a culture would have succeeded in making man submit to its patterns without resistance. But man, being only relatively malleable, has always reacted with protest against conditions which made the disequilibrium between the social order and his human needs too drastic or unbearable. The attempt to reduce this disequilibrium and the need to establish a more acceptable and desirable solution is at the very core of the dynamism of the evolution of man in history. Man's protest arose not only because of material suffering; specifically human needs...are an equally strong motivation for revolution and the dynamics of change.”
