This seems like an over-simplification with the express purpose of proving the Bible. Something I have never EVER understood is the continual search for verification when your faith charges you to believe without proof. It seems so rude to your Lord... but then, most Biblical converts needed miracles in order to believe despite what the Christ said. Maybe people will never change. Just remember a few words here:
John 2
[23]
Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did.
[24]
But Jesus did not commit himself unto them, because he knew all men,
[25]
And needed not that any should testify of man: for he knew what was in man.
John 3
[11]...
We speak that we do know, and testify that we have seen; and ye receive not our witness.
[12]
If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
John 4
[48] Then said Jesus unto him,
Except ye see signs and wonders, ye will not believe.
And he didn't say that as though it were a Good Thing!
John 5
44]
How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
[45]
Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom ye trust.
[46]
For had ye believed Moses, ye would have believed me: for he wrote of me.
[47]
But if ye believe not his writings, how shall ye believe my words?
Nevertheless... as I said, this thesis is vast over-simplification. For example, here are some Chinese words for garden -- you'll have to go to this link:
China Language words for Garden
Even the Chinese word which seems closest to the one you mention has an additional character on top which your history lesson doesn't note. One has to wonder why... could it be that it won't fit nicely into the theory?
Here is is the Chinese word for paradise... music + garden:
樂園
How does this give you some proof? I don't see it.
As for... devil... first off, remember, the Chinese word for garden is, in fact, different from what the Morgenstern essay says. I'd also like to point out to you (just for a little twist) that this word "devil" is also used in combination with man or woman to mean Caucasian. See
here.
The Chinese word for human is simplified, see
here as is the word for secret. See
here. It just boggles my mind that Morgenstern would use false logic to try to prove a faith that requires belief without proof... and especially to teach it the young.
Go ahead and look up the rest of the words mentioned in Morgenstern on any Chinese dictionary and see for yourself how this has been oversimplified into a sad facsimile of false proofs. They ought to be ashamed.
