Civilization degrades many in order to exalt the few.

Nature is the armory of genius. Cities serve it poorly, books and colleges at second hand; the eye craves the spectacle of the horizon; of mountain, ocean, river and plain, the clouds and stars; actual contact with the elements, sympathy with the seasons as they rise and roll.

Success is sweet and sweeter if long delayed and gotten through many struggles and defeats.

Traveling is no fool's errand to him who carries his eyes and itinerary along with him.

Books are the most mannerly of companions, accessible at all times, in all moods, frankly declaring the author's mind, without offense.

The true teacher defends his pupils against his own personal influence. He inspires self-trust. He guides their eyes from himself to the spirit that quickens him. He will have no disciples.

Conversation is an abandonment to ideas, a surrender to persons.
