You said that knowing is having information that is congruent to the object being known. My question, since you missed it, is how are sequences of electrochemical reactions congruent to the object being known?
By acceptance. By applying them to the external reality. Let’s consider a simple example. According to our observations the sand and acid have no nutritional value. On the other hand, bread and water are nutritious. By attempting to take them, we shall verify that our electro-chemical processes correctly describe the reality.
Let’s take an example about learning, even though you already understand it. But an example might still be useful. (Personally, I am very visual.)
Suppose we (you and I) have no common language, but wish to learn to communicate. (You speak English, and I speak Hungarian. I do speak several languages, and Hungarian is one one of them.
) You pick up an “apple”, show it to me, and say: “apple”. I will see the object, hear the word you said, and associate the object with the word. I look at it, and in my language (let it be Hungarian - good, esoteric language) it is “alma”. Now the elecro-chemical neural “footprint” in your brain (when thinking about the apple) is very different from mine (when I think about the Hungarian equivalent “alma”). How do we know that we
MEAN the same thing? By silent
AGREEMENT. Usually we both repeat the words, to allow the proper modification of the neural network, to memorize the new words. And that is all. For the same object, we both store an electro-chemical “footprint” (for lack of a better word) and even though the neurons and their surroundings are very different, we AGREE that they point to the same object - and as such they are congruent.
Moreover, how do you KNOW that I
understand you? By conducting a conversation (as long as necessary), and as long as I use the words according to the rules of grammar, and the conversation “makes sense” you you, you will accept that I understand you - even though you have no access to my neural network, and even you had, my neurons are totally different from yours. This is why the Turing test is so important, and that is why the “Chinese room” (
Chinese room - Wikipedia) is so udderly irrelevant. (Yes, the pun was intentional or “indentional”? )
