“But what you’re talking about means giving up all that—just the noble primitive, simple and self-sufficient. He’s going to chop down a tree— He wants to shoot a deer—...There never was and there never could be a noble simple creature such as you described. He’d be an ignorant savage, with dirt on his skin and lice in his hair. He would work sixteen hours a day to stay alive at all. He’d sleep in a filthy hut on a dirt floor. And his point of view and his mental processes would be just two jumps above an animal.â€
