“We neglect mind. We need not consider brain; a duly nourished and duly exercised mind takes care of its physical organ provided that organ also receives its proper material nourishment. But our fault, our exceeding great fault, is that we keep our own minds and the minds of our children shamefully underfed. The mind is a spiritual octopus, reaching out limbs in every direction to draw in enormous rations of that which under the action of the mind itself becomes knowledge. Nothing can stale its infinite variety; the heavens and the earth, the past, the present, and future, things great and things minute, nations and men, the universe, all are within the scope of the human intelligence.” Mind Book:A Philosophy of Education Source: A Philosophy of Education
