It is part of the educator's responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.
John DeweyFailure is instructive. The person who really thinks learns quite as much from his failures as from his successes. Genuine ignorance is profitable because it is likely to be accompanied by humility, curiosity, and open-mindedness; whereas ability to repeat catch-phrases, can't terms, familiar propositions, gives the conceit of learning and coats the mind with varnish waterproof to new ideas.
John DeweyThe problem of restoring integration and co-operation between man's beliefs about the world in which he lives and his beliefs about values and purposes that should direct his conduct is the deepest problem modern life. It is the problem of any philosophy that is not isolated from life.
