There are reasons why he was immensely popular among hippies and back-to-nature freaks. One thing that says to me is that, although the environmental movement has been kidnapped by leftists, it is, or ought to be, a fundamentally a conservative thing. Too many Freepers want to repudiate environmentalism, when what we need to do is take it back from the leftists and the economic illiterates and restore it to what should be.
The error the left makes is to worship the creation, not the Creator. And in worshiping the Creator, repecting his works of his Hands. This to me is an honorable enviormentalism.
Strange that he refused to ride in a car, or hated machinery. I didn't know this. This is typical of commune-loving hippy types who want to regress rather than progress.
Remember, Pol Pot from Cambodia who forced everyone out of the city to go "back to nature". Not a nice philosophy to not believe in human progress.
