The moral arc of the universe bends at the elbow of justice.

The Christians who engaged in infamous persecutions and shameful inquisitions were not evil men but misguided men. The churchmen who felt they had an edict from God to withstand the progress of science, whether in the form of a Copernican revolution or a Darwinian theory of natural selection, were not mischievous men but misinformed men. And so Christ's words from the cross are written in sharp-edged terms across some of the most inexpressible tragedies of history: 'They know not what they do'.

People with good intentions but limited understanding are more dangerous than people with total ill will.

Just as Socrates felt that it was necessary to create a tension in the mind so that individuals could rise from the bondage of myths and half-truths to the unfettered realm of creative analysis and objective appraisal, so must we see the need for nonviolent gadflies to create the kind of tension in society that will help men rise from the dark depths of prejudice and racism to majestic heights of understanding and brotherhood.

I am not afraid of the word tension.

What affects one in a major way, affects all in a minor way.
