What sort of space is that which separates a man from his fellows and makes him solitary?
Henry David ThoreauThe intellect of most men is barren. They neither fertilize or are fertilized. It is the marriage of the soul with nature that makes the intellect fruitful, that gives birth to imagination...without nature-awakened imagination most persons do not really live in the world, they merely pass through it as they live dull lives of quiet desperation.
Henry David ThoreauWe boast of our system of education, but why stop at schoolmasters and schoolhouses? We are all schoolmasters, and our schoolhouse is the universe. To attend chiefly to the desk or schoolhouse while we neglect the scenery in which it is placed is absurd. If we do not look out we shall find our find schoolhouse standing in a cow-yard at last.
