The mind is not a vessel that needs filling but wood that needs igniting.

The image rejects the “banking” model of education in which knowledge is deposited into a passive mind. A “vessel” suggests storage and quantity; “wood that needs igniting” suggests energy, transformation, and self-sustaining activity. The point is not that facts are useless, but that learning becomes meaningful when it kindles curiosity, judgment, and moral purpose—capacities that continue to generate understanding beyond any fixed curriculum. The metaphor also implies a teacher’s role is catalytic: to spark attention and love of wisdom, so that the learner actively participates in making knowledge their own rather than merely retaining it.
