Isn't that a bit like saying that red and blue colours are categorically unlike yellow colours? It's just pretty much saying the obvious, in other words that different things are different. I completely miss the point of the statement.BobEnyart said:dog barks and animal sounds are categorically unlike human language
On the second read through of Bob's point about language I saw one other thing. He's attacking Aron's claim that there was no Tower of Babel and no supernatural seperation into different languages by attacking the actual developement of language itself. As far as I know we have pretty hefty amount of evidence that one language can "evolve" from another language. After all almost every one of you couldn't understand the language your forefathers were speaking a thousand years ago and different ones can be shows to have "evolved" from an common ancestor. What Bob seems to be doing is akin to attacking evolution by attacking abiogenesis.
That, and getting a cheap shot at what Bob really must believe is the inerrant prophet of evolution, Charles Darwin.
