He who learns but does not think, is lost! He who thinks but does not learn is in great danger.

The superior man does not, even for the space of a single meal, act contrary to virtue. In moments of haste, he cleaves to it. In seasons of danger, he cleaves to it.

He who learns but does not think, is lost! He who thinks but does not learn is in great danger.

A man who carries a cat by the tail learns something he can learn in no other way.

He who laughs most, learns best.

The great man is he who does not lose his child's-heart.
