"For more than twenty years by my own work and personal initiative, I have gathered from all the old streets of Vieux Paris photographic plates, 18 x 24 format, artistic documents of the beautiful civil architecture of the 16th to the 19th century: the old hôtels, historic or curious houses, beautiful facades, beautiful doors, beautiful woodwork, door knockers, old fountains This vast artistic and documentary collection is today complete. I can truthfully say that I possess all of Vieux Paris."

..there is need for a person to be generally educated. Otherwise you shrivel up much too soon. Whether this means reading the bible (I read the New Testament every few years) or reading the great 19th century novelists (the greatest and shrewdest judge of people and of society who ever lived), or classical philosophy (which I cannot read-it puts me to sleep immediately), or history (which is secondary). What matters is that the knowledge worker, by the time he or she reaches middle age, has developed and nourished a human being rather than a tax accountant or a hydraulic engineer.
