No one man, however brilliant or well-informed, can come in one lifetime to such a fullness of understanding as to safely judge and dismiss the customs or institutions of his society, for these are the wisdom of the generations after centuries of experiment in the laboratory of history. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.
Historians are pessimists because they ignore the banks for the river.
Knowledge is the eye of desire and can become the pilot of the soul.
