"In the heated idleness of youth we were all rather inclined to quarrel with the implication of that proverb which says that a rolling stone gathers no moss. We were inclined to ask, "Who wants to gather moss, except silly old ladies?" But for all that we begin to perceive that the proverb is right. The rolling stone rolls echoing from rock to rock; but the rolling stone is dead. The moss is silent because the moss is alive."
