The greatest danger

I'm reading Abraham Joshua Heschel's great work, The Prophets. Came across this yesterday and it seems appropriate for our time, when outrageous evils are happening every day:

There is an evil which most of us condone and are even guilty of: indifference to evil. We remain neutral, impartial, and not easily moved by the wrongs done unto other people. Indifference to evil is more insidious than evil itself; it is more universal, more contagious, more dangerous. A silent justification, it makes possible an evil erupting as an exception becoming the rule and being in turn accepted.—Abraham Joshua Heschel, The Prophets, 2:64
