The meeting edge of man and the world is also his cutting edge. If man is active, it is exactly here where experience comes in that it is delivered back, and if he stays fresh at the coming in he will be fresh at his going out. If he does not, all that he does inside his house is stale, more and more stale as he is less and less acute at the door. And his door is where he is responsible to more than himself.
