We all strive for safety, prosperity, comfort, long life, and dullness. The deer strives with his supple legs, the cowman with trap and poison, the statesman with pen, the most of us with machines, votes, and dollars. A measure of success in this is all well enough, and perhaps is a requisite to objective thinking, but too much safety seems to yield only danger in the long run. Perhaps this is behind Thoreau's dictum: In wilderness is the salvation of the world. Perhaps this is the hidden meaning in the howl of the wolf, long known among mountains, but seldom perceived among men.
For money you can have everything it is said. No, that is not true. You can buy food, but not appetite; medicine, but not health; soft beds, but not sleep; knowledge but not intelligence; glitter, but not comfort; fun, but not pleasure; acquaintances, but not friendship; servants, but not faithfulness; grey hair, but not honor; quiet days, but not peace. The shell of all things you can get for money. But not the kernel. That cannot be had for money.
