英语翻译如何翻译“要想知道梨子的味道,必须亲口尝一尝”

原话好象是毛泽东的：“。。。你要知道梨子的味道,你就得变革梨子,亲口吃一吃。你要知道革命的理论和方法,你就得参加革命。实践出真知”——毛泽东有两种译法：“The only way to know the taste of a pear is to eat it。” “If you want to know the taste of a pear,you must change the pear by eating it yourself。If you want to know the theory and methods of revolution,you must take part in revolution。All genuine knowledge originates in direct experience。”
