Right. That’s the problem.
A character on the screen, though it is composed of no more than pixels, is at least a physical entity. But it’s a signifier.
And signification is not a physical thing. It’s a cognitive one.
That a letter “T” is in front of you now is a physical fact: but that it is the commencement of the word “Thus,” and that it makes you think of a consequence-utterance to follow, those are seemings in a mind, not mere electrons in a brain. For electrons, qua electrons, do not “mean” things. It takes a mind on the other end of the email to cause the pixels to “mean” things to me, and my mind to decide what they “mean.”
So there really is no explaining that on purely physical terms. We can account for the existence of the “T” shape that way, but not for the fact that it precipitates a word or idea in a human consciousness.
Two people speaking to each other are communicating with sounds, or audible symbols, that represent ideas, and they can see one another. But what if they were both deaf, and communicating with sign language? What if they were blind and could only hear each other? Does it make a difference if they are in seperate rooms? Maybe it's a telephone conversation, where they might be 100 yards apart, or 100 miles apart, and communicating only with audible symbols that represent their thoughts. What is the difference in principle between a letter and an email?
No important difference, for this discussion. But the word “communicating” implies an action that physical things cannot do. Rocks do not “communicate.” Nor do electrons. Nor do the atoms in a human body.
It takes the presence of minds for anything called “communication” to happen.
In every case the communication is conducted purely by physical means. The only real difference is the varying proximity of the participants. And if you say that a visible word on a screen is only a signifier, and signification is not a physical thing, why do you regard a spoken word to be a signifier with a signification that is a physical thing?
Again, you use the word “communication.” But it is not “conducted purely by physical means.” Rather, it’s a cognitive action performed
through the tools of physical writing. But the primary action you’re identifying, “communication” is not itself physical. It’s cognitive.
We must not mistake the tool used for the substance of the communicating. To illustrate, one could fold up a piece of paper and mail it to a friend. In such a case, “mailing” would have take place, but no “communication.” On the other hand, you could use smoke signals; and if he knew how to “read” them, then communication would be taking place, though the physical means would be no more substantial than smoke. And usually, smoke does not mean anything more than that random combustion is taking place. So the tools and the message are not the same thing at all. The former is the means; the latter is the message.
