"We should free ourselves from the narrowness of being related only to those familiar to us, either by the fact that they are blood relations or, in a larger sense, that we eat the same food, speak the same language, and have the same " common sense." Knowing men in the sense of compassionate and empathetic knowledge requires that we get rid of the narrowing ties of a given society, race or culture and penetrate to the depth of that human reality in which we are all nothing but human. True compassion and knowledge of man has been largely underrated as a revolutionary factor in the development of man, just as art has been. It is a noteworthy phenomenon that in the development of capitalism and its ethics, compassion (or mercy) ceases to be a virtue."
