再查一下，此言出自（泰倫斯）Publius Terentius Afer (195/185–159 BC).

One famous quotation by Terence reads: "Homo sum, humani nihil a me alienum puto", or "I am a human being, I consider nothing that is human alien to me."This appeared in his play Heauton

莫非泰倫斯也有私生子？或是泰倫斯的話劇HEAUTON是關於私生子的？

下麵這篇介紹馬克思主義的文章開篇就提到這句話。

 Terentius’ statement, “I believe that nothing human is alien to me,” was an expression of the Humanist spirit, echoed centuries later by Goethe’s “Man carries within himself not only his individuality but all of humanity, with all its potentialities, although he can realize these potentialities in only a limited way because of the external limitations of his individual existence.”

誰能從這裏讀出私生子的話，I　服了　U。
