Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home. – John Dewey
Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes. – John Dewey
A person who is trained to consider his actions, to undertake them deliberately, is in so far forth disciplined. Add to this ability a power to endure in an intelligently chosen course in the face of distraction, confusion, and difficulty, and you have the essence of discipline. – John Dewey
