"Human social life, I suggest, is the magma that erupts and builds up, so to speak, at the fault lines where natural human capacities meet and grind against and over natural human limitations…. This meeting of powers and limitations produces a creative, dynamic tension and energy that generates and fuels the making of human social life and social structures…. It is real human persons living through the tensions of natural existential contradictions who construct patterned social meanings, interactions, institutions, and structures."
