Some may ask by what right I address you. I have no formal title; I am not any part of the machinery of government. I speak only because I must ; because others, who should have remembered civilisation and human brotherhood, have allowed themselves to be swept away by national passion; because I am compelled by their apostasy to speak in the name of reason and mercy, lest it should be thought that no one in Europe remembers the work which Europe has done and ought still to do for mankind.
