The question isn't if I know of any, the question is if you do. And apparently, you don't.
If you can't point to a real atheist actually making the mind-brain identicality argument (as opposed to simple equivalence), then you are fabricating the argument and you are presenting it as an opponent's (here referred to as certain atheists) argument and you are claiming them defeated. That is a quintessential strawman.

You are the one who concluded that. That's your conclusion word for word. Are you now denying your own argument?

That it is a phenomenon dependent on a functioning brain.

Glad we agree. Now apply the same standard to your own argument.
Ignoring mind's essential nature doesn't actually change its essential nature. That you can imagine mind as a disembodied spirit doesn't make it so - the same way my imagining a bachelor to be "man who lives alone" doesn't make it so. Which is why a mind independent of brain is as conceivably and logically impossible as a married bachelor.
(October 6, 2013 at 8:54 am)Rational AKD Wrote: no, it's not. I can use the actual definitions of mind and brain whereas you had to redefine them.
But you have to ignore the logical implications of those definitions - which is, in effect, a redefinition.

A descriptive addition does not change the essential nature of the entity. A red apple is still an apple and a winged horse is still a horse.

The movies presume that mind and body are two distinct, independent entities. Which is why they can conceive of mind existing independently form the body. Using that conceived possibility, you are attempting to show that mind and body are are two distinct entities. The conclusion is exactly the same as the premise. Thus, circular reasoning.
