Movement means friction.
Only in the frictionless vacuum of a nonexistent abstract world can movement or change occur without that abrasive friction of conflict. It is change, continuing change, inevitable change, that is the dominant factor in society today. This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking. Lord Byron To remain young one must change. The perpetual campus hero is not a young man but an old boy.
