Please provide a definition of "associate a meaning to the symbol" that can be applied to a human brain and not a computer.

The plain reading of what you've written above is so trivially simple to implement in a computer that it is covered in every introductory algorithm course, so I presume you have either given a definition of "meaning" that is overly simplistic, or have a definition of "associate a meaning" that is substantially more complicated than a plain reading of the words.
