Science, my lad, is made up of mistakes

“Science, my lad, is made up of mistakes” is a remembered line from Jules Verne that gives a quiet scene of escape an intellectual counterpoint. As Marie-Laure LeBlanc and Etienne LeBlanc climb out through a wardrobe and find no soldiers waiting in the hall, the words turn ordinary uncertainty into part of the search for truth.

The Line in the Scene

The sentence comes back to Marie-Laure after she and Etienne descend a ladder and clamber out through the wardrobe. Their emergence brings no visible change: no soldiers wait in the hall with guns drawn, and nothing seems different. Against this suspended quiet, the remembered passage offers a way to understand knowledge as something reached gradually, rather than possessed all at once.

Mistakes and Gradual Knowledge

The full line explains that mistakes are useful because they lead “little by little to the truth.” Its emphasis is not on error as a triumph in itself, but on the value of learning through incomplete attempts. The recollection also links the scene to the pair’s exchange about whether such experiences translate into words: after Etienne laughs and asks whether Marie-Laure remembers Madame Manec’s boiling-frog example, she confirms that she does. The reference to Verne thus sits beside another remembered lesson, joining scientific trial and attentive observation as ways of making sense of what happens.
