Are words more than their symbols?
Like I said, I’m leaning more towards meaning as a biological act. The thing, its location, is the biology. To mean, like thinking, understanding, speaking, and so on, is something the biology does.
I don’t think I can provide a biological account of proper names or any other phrase because there is nothing biological about proper names. I have already said the words are arbitrary and conventional. What I can say is those who have taken up the task of staring at words and sentences in order to divine some coherent philosophy are largely overlooking the most important structures involved in producing them, and as such language in general. I suspect that the most coherent answers will be provided by fields such as biolinguistics.
