There are those who look at Nature from the standpoint of conventional and artificial life—from parlor windows and through gilt-edged poems—the sentimentalists. At the other extreme are those who do not look at Nature at all, but are a grown part of her, and look away from her toward the other class—the backwoodsmen and pioneers, and all rude and simple persons. Then there are those in whom the two are united or merged—the great poets and artists. In them the sentimentalist is corrected and cured, and the hairy and taciturn frontiersman has had experience to some purpose. The true poet knows more about Nature than the naturalist because he carries her open secret in his heart. Eckerman could instruct Goethe in ornithology, but could not Goethe instruct Eckerman in the meaning and mystery of the bird?
