I prefer the folly of enthusiasm to the indifference of wisdom.

The aphorism sets “enthusiasm” (ardor, commitment, the willingness to care) against a sterile “wisdom” that has become indifferent. Calling enthusiasm a “folly” concedes that passion can be naïve, excessive, or mistaken; yet the speaker prefers that risk to the emotional and ethical deadness of detached knowing. The point is less anti-intellectual than anti-cynical: a society (or individual) that prides itself on being too wise to be moved may lose the capacity for solidarity, creativity, and moral action. France suggests that errors made in the service of feeling and engagement can be more human—and more fruitful—than correct conclusions that lead to apathy.
