有识亦应有胆，这是成为伟人的要素。知识与勇气是不朽的，同样可使人不朽。懂得多少，便有多伟大；若你学识渊博，则无事不可为。一个人无知，正如世界没有光明。智慧与力量，就像双眼与双手。有识无胆者亦无所成。
knowledge and courage are the elements of greatness. they give immortality, because they are immortal. each is as much as he knows, and the wise can do anything. a man without knowledge, a world without light. wisdom and strength, eyes and hands. knowledge without courage is sterile.
