Some connection, if only this: that every fulfillment this side of Heaven instantly reveals its inadequacy. It is immediately evident that such satisfactions are not enough; they are not what we have really sought; they cannot really satisfy us at all.

Unless we regain the art of silence and insight, the ability for nonactivity, unless we substitute true leisure for our hectic amusements, we will destroy our culture and ourselves.

All just order in the world is based on this, that man give man what is his due.
