英汉对译论语十则(4)

子曰：「吾十有五而志于学, 三十而立, 四十而不惑, 五十而知天命, 六十而耳顺, 七十而从心所欲, 不逾矩。」
　　Confucius said: "At fifteen my heart was set on learning; at thirty I stood firm; at forty I had no more doubts; at fifty 　I knew the mandate of heaven; at sixty my ear was obedient; at seventy I could follow my heart’s desire without transgressing the norm."
