I had reservations in Capernaum

The mistake is so obvious, so dangerous, so simple.  The convolution of the ideas, of the words themselves, of belief on the one hand, and truth on the other creates a muddle for the individual and for the culture at large.  J describes the essential confusion that comes with this confidence that the mere presence of belief makes something true.  

She opines, "The Inquisition, Pol Pot's violence, Hitler's final solution, do not occur outside of the misguided certainty of true believers.  Smaller but no less personally grave, the acts of cruelty both physical and mental that occur between individuals, occur in the shadow of one or both parties sense that his or her execution of justice is buoyed by some concrete truth that they are privy to."  

This is a force--at all levels--that belies the human discomfort with lingering questions and with their own separation--intrinsic and incurable--from others.  Rather than adapting to an honest uncertainty, the individual--be he dictator, desperate lover, or petulant child--is moved to action by the deliberate translation of his or her truth into justice.   Humility, sometimes considered a religious virtue and always appreciated as social skill, and doubt, the anchor of scientific knowledge, call into question the arrogance of "knowing."
