When I have a physical experience, sometimes it results in me saying a word.

Now, maybe there are other possible experiences that would result in me behaving identically, such that from my behavior (including what words I say) it is impossible to distinguish between different potential experiences I could have had.

But, “caused me to say” is a relation, is it not?

Unless you want to say that it wasn’t the experience that caused me to do something, but some physical thing that went along with the experience, either causing or co-occurring with the experience, and also causing me to say the word I said. But, that would still be a relation, I think.

Yes, but it's a unidirectional relation: it was the result of the experience. The word cannot represent the context (the experience), in a meaningful way.

It's like trying to describe a color to a blind person: poetic subjective nonsense.

I don’t know what you mean by “unidirectional relation”. I get that you gave an explanation after the colon, but I still don’t quite get what you mean. Do you just mean that what words I use doesn’t pick out a unique possible experience? That’s true of course, but I don’t know why you call that “unidirectional”

I don’t think describing colors to a blind person is nonsense. One can speak of how the different colors relate to one-another. A blind person can understand that a stop sign is typically “red”, and that something can be “borderline between red and orange”, but that things will not be “borderline between green and purple”. A person who has never had any color perception won’t know the experience of seeing something red or blue, but they can still have a mental model of the world that includes facts about the colors of things, and what effects these are likely to have, even though they themselves cannot imagine what it is like to see the colors.

IMO, the GP's idea is that you can't explain sounds to a deaf man, or emotions to someone who doesn't feel them. All that needs direct experience and words only point to our shared experience.

Ok, but you can explain properties of sounds to deaf men, and properties of colors to blind men. You can’t give them a full understanding of what it is like to experience these things, but that doesn’t preclude deaf or blind men from having mental models of the world that take into account those senses. A blind man can still reason about what things a sighted person would be able to conclude based on what they see, likewise a deaf man can reason about what a person who can hear could conclude based on what they could hear.
