"Life knows us not and we do not know life,—we don't know even our own thoughts. Half the words we use have no meaning whatever and of the other half man understands each word after the fashion of his own folly and conceit. Faith is a myth and beliefs shift like mists on the shore: thoughts vanish: words, once pronounced, die: and the memory of yesterday is as shadowy as the hope of tomorrow,—only the string of my platitude seems to have no end. As our peasants say: "Pray brother, forgive me for the love of God." And we don't know what forgiveness is, nor what love, nor where God is."
