Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home; that wildness is a necessity; and that mountain parks and reservations are useful not only as fountains of timber and irrigating rivers, but as fountains of life.
There is a pleasure in the pathless woods, there is a rapture on the lonely shore, there is society where none intrudes, by the deep sea, and music in its roar: I love not Man the less, but Nature more.
Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop away from you like the leaves of autumn.
A man is rich in proportion to the number of things which he can afford to let alone.
I am no more lonely than the loon in the pond that laughs so loud, or than Walden Pond itself. I am no more lonely than a single mullein or dandelion in a pasture, or a bean leaf, or a housefly, or a bumblebee. I am no more lonely than the Mill Brook, or a weathercock, or the north star, or the south wind, or an April shower, or a January thaw, or the first spider in a new house.
In my walks I would fain return to my senses. What business have I in the woods, if I am thinking of something out of the woods?
