I've found them to be close in relation to Thoreau and Emerson, especially John Muir. He's a fanatic and puts Thoreau and Emerson bluntly, pretty much calling us sloths.
If you're into the simplistic side of Transcendentalism, and aren't into consumerism and spending $500,000 for a stucco box with vaulted ceilings, or a $50,000 machine that takes up two lanes of traffic and you require a $500 cell phone/i pod/computer to talk to the person in the back seat because you can't hear them over the headrest tv's, I would read the book Culture Jam
It's possibly the greatest $13 you'll ever spend
Seriously, it's an amazing piece of work :)
