Genuine ignorance is… profitable because it is likely to be accompanied by humility, curiosity, and open mindedness; whereas ability to repeat catch-phrases, cant terms, familiar propositions, gives the conceit of learning and coats the mind with varnish waterproof to new ideas. – 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
