愛因斯坦有段文字挺讓人刮目相看，

從他的非學術文集中讀到的。When Einstein was a youth, he noticed that everything that supported his life was not made by himself: food that fed him, clothes that covered him, languages that connected him to others, physics that he was learning...

He saw 因緣 even when he was a youth! This impressed me more than his later activities in physics. No wonder he turned out an Einstein.
