“When I look at a chair, I say I experience it. But what I actually experience is only a very few of the elements that go to make up the chair, namely, that colour that belongs to the chair under these particular conditions of light, the shape which the chair displays when viewed from this angle, etc. The man who has the experience, as distinct from a philosopher theorizing about it would probably say that he experienced the chair most fully not when looking at it but when meaning to sit down in it precisely because his experience is not limited to colour under specific conditions of light, and angular shape.”

—John Dewey, inventor of the Dewey Decimal System, from Experience and Nature, 1925. Quoted in Experiential Learning: A Best Practice Handbook for Educators and Trainers by Colin Beard and John P. Wilson, second edition, 2006.
