"Frank's argument is similar to the "my cellphone generates all kinds of interesting messages" assertion. The wiring may definitely be mappable to the sending of messages, but that is no certain demonstration that it generates them. It could similarly be argued that asserting that understanding is brought about solely by brain mechanics is comparable to asserting that your cell phone understands the messages people leave on it, and saves them and relays them to you with comprehension, which is silly on the face of it."

Amos, your analogy doesn't hold. A cellphone is a mechanical contrivance that if it doesn't serve by sending messages, why even bother with one? The brain, by contrast, is capable
of understanding messages that is not like the physical principles involved in the cellphone.
To claim that the cellphone can of itself comprehend messages is fallacious, of course, but the human brain is not a cellphone. The brain can comprehend a message and respond to it whereas a cellphone can not. The human brain can generate messages and without its activity, there will be no sending of messages on a cellphone. The human brain is genetically mapped to send and receive messages unlike a cellphone.
