Crucial to understanding.

“It is not enough to insist upon the necessity of experience, nor even of activity in experience. Everything depends on the quality of the experience which is had ….
Just as no man lives or dies to itself, so no experience lives or dies to itself. Wholly independent of desire or intent, every experience lives on in further experiences. Hence the central problem of an education based upon experience is to select the kind of experiences that live fruitfully and creatively in subsequent experiences.”
— John Dewey, Experience and Education
