There is nothing terrably wrong with the essay Self Reliance and there is nothing of CEDU in it.
With regard to other sites, heed the words of Ginger. Evil can very quickly advance upon good.
For example the Cult Awarnes Network is now owned by the Church of Scientology - They won it in a lawsuit and it continuse to develop a list of people it considers fair game.
Now, again, with regard to Ralph Waldo Emerson and Self Reliance. CEDU or not, he was a progressive master of free thought. CEDU used Emerson to promote its own grandiosity and to create the false perception that CEDU embraced the values in Self Reliance (this is a straw man fallicy) and, let's face it pure CEDU Bullshit.
If you read the whole Emerson Essay called "Self Reliance" you will see that Emerson hated authority, hated dogma, hated conformity, hated self agrandisement and would have hated CEDU with a passion unmatched by the fires of a burning hell. God bless him.
Emerson stated the following:
"He who is a man must be a nonconformist. He who would gather immortal palms must not be hindered by the NAME of goodness (cedu) but first must determine if it be goodness."
Clearly CEDU personifies the opposite. They would say the following:
"he who is a man must conform to the CEDU system 110%. He who would gather immortal palms must "buy in" to all our dogma or be excommunicated because CEDU is all perfect, all good, all knowing, without any flaw. Anyone who questions CEDU, thinks for himself, or is a critical thinker in any way, is to be cast out and damned to hell" - all Mormons trancending. HA HA HA (couldn'r resist, afrer all the "Gods" of cedu so resemble the future Gods of Moroni).
So don't kill literature (the messinger) because a tyrant power structure uses the messaage as a tool to brainwash. CEDU is full of shit, Emerson is not.
Part of critical thinking, my friend, is reading and drawing inferances from objective positions of differing perspectives. Moving around and looking from differing areas of perception and ideology is key. Doing less is no better than embracing the tyrant, CEDU in this case, as literal truth. So let intellect, not bias, rule the day. Read the Essay and judge it accordingly. You will find that it is not pure truth (nothing is). You will find a few flaws buried in diamonds of brilliance - The same brilliance upon which this country was intended to be based, and the way back home.
