To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates.
成为哲学家不仅仅是有微妙的思想，甚至也不是建立一个学派，而是如此热爱智慧以至于按照它的指示生活。
"The immune system is like a double-edged sword; it can fight cancer but also needs to be controlled."
The condition of man... is a condition of war of everyone against everyone.
