"It is a pleasure to stand upon the shore, and to see ships tost upon the sea: a pleasure to stand in the window of a castle, and to see a battle and the adventures thereof below: but no pleasure is comparable to standing upon the vantage ground of truth . . . and to see the errors, and wanderings, and mists, and tempests, in the vale below."

Half the walk is but retracing our steps. We should go forth on the shortest walk, perchance, in the spirit of undying adventure, never to return-prepared to send beck our embalmed hearts only as relics to our desolate kingdoms. If you are ready to leave father and mother, brother and sister, and wife and child and friends and never see them again,-if you have paid your debts and made your will, and settled your affairs and are a free man, then you are ready for a walk.

— Henry David Thoreau
