He who laughs most, learns best.

The line links humor with effective learning: laughter lowers anxiety, increases attention, and makes ideas more memorable, so the person who can laugh (or be made to laugh) is more receptive to new information. Read as advice, it encourages teachers and communicators to use wit to create psychological safety and engagement rather than relying on intimidation or solemnity. It also implies that learning is not merely dutiful absorption but an active, pleasurable process—curiosity thrives when the stakes feel manageable. In a broader cultural sense, it reflects a modern view of education and creativity in which playfulness is not the enemy of seriousness but one of its most productive tools.
