I must walk more with free senses. It is as bad to study stars and clouds as flowers and stones. I must let my senses wander as my thought, my eyes see without looking . . . Be not preoccupied with looking. Go not to the object; let it come to you . . . What I need is not to look at all, but a true sauntering of the eye.

— Henry David Thoreau, A Natural History of Nature Writing by Frank Stewart
