A few quotes from renowned educationist, John Dewey.
"Education, therefore, is a process of living and not a preparation for future living".
"Every great advance in science has issued from a new audacity of imagination".
"Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes".
"Man is not logical and his intellectual history is a record of mental reserves and compromises. He hangs on to what he can in his old beliefs even when he is compelled to surrender their logical basis".
