If we had no winter, the spring would not be so pleasant; if we did notsometimes taste of 

      adversity, prosperity would not be so welcome.------Bradstreet, "Meditations Divine & Moral"

         如果没有冬天,春天不会如此悦人; 如果人们不是有时得尝尝不幸,幸运不会如此受人欢迎.

                                                           ------布雷史崔,〈神圣与道德之沉思〉
