Ralph Waldo Emerson in his famous book ´Nature´ (1838) said that "A nobler want of man is served by nature, namely, the love of Beauty. (...) The simple perception of natural forms is a delight. The influence of the forms and actions in nature, is so needful to man, that, in its lowest functions, it seems to lie on the confines of commodity and beauty. To the body and mind which have been cramped by noxious work or company, nature is medicinal and restores their tone. The tradesman, the attorney comes out of the din and craft of the street, and sees the sky and the woods, and is a man again. In their eternal calm, he finds himself. The health of the eye seems to demand a horizon. We are never tired, so long as we can see far enough".
