The business of education is not to make the young perfect in any one of the sciences， but so to open and dispose their minds as may make them capable of any， when they shall apply themselves to it.
教育的目的不是使年轻人在任何一门科学上都变得完美，而是要打开和培养他们的思维，使他们在将来学习任何科学时都能胜任。
译文：即便我改变了外在的样子，人们依然难以领悟真谛，那些如同行尸走肉般生活的人，我并不为之忧虑。我要尽情地回归质朴纯真，哪怕被人嘲笑不够潇洒风流。
If I have seen further, it is by standing on the shoulders of giants.
You use a glass mirror to see your face; you use works of art to see your soul.
