孔子曰：“生而知之者，上也；学而知之者，次也：困而学之，又其次也；困而不学，民斯为下矣。”
1Confucius said, 'Those who are born with the possession of knowledge are the highest class of men. Those who learn, and so, readily, get possession of knowledge, are the next. Those who are dull and stupid, and yet compass the learning, are another class next to these. As to those who are dull and stupid and yet do not learn;-- they are the lowest of the people.'
