If the gentleman is not serious, he will not be respected, and his learning will not be on a firm foundation. He considers loyalty and faithfulness to be fundamental, has no friends who are not like him, and when he has made mistakes, he is not afraid of correcting them.
ConfuciusHe who learns but does not think, is lost! He who thinks but does not learn is in great danger... Men of superior mind busy themselves first getting at the root of things; when they succeed, the right course is open to them.
Confucius
