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'.
Martin Luther King, Jr.The potential beauty of human life is constantly made ugly by man's ever recurring song of retaliation. The oceans of history are made turbulent by the ever rising tides of revenge. Man has never risen above the injunction of the lex talionis: "Life for life, eye for eye, tooth for tooth, hand for hand, foot for foot." In spite of the fact that the law of revenge solves no social problems, men continue to follow its disastrous leading. History is cluttered with the wreckage of nations and individuals that pursued this self-defeating path.
