In all seriousness, I don't know that all conversation is to control. Some is to clarify, some is to query, some is to request, etc. Some is to genuinely understand, and that is truly noble. The Word says, "in all your getting get understanding." (Prov. 4:7)
My brain hurts now. I don't often think that deep.
Wittgenstein had categories (I’m digging back 50 years!) for ordinary language games which cover some of what you are referring to.
On the other hand there’s a very old mystical Christian tradition found in the Benedictines and other orders of taking a vow of silence. To oversimplify, our fallen nature is such that most of our words are useless and frivolous and filled with pride. We use them to puff ourselves up, manipulate others, and to reassure ourselves that we are in control of our own lives, forgetting that our lives are not ours.
But you’re right, this is too deep. I’ve cobbled together a lot of ideas and not done justice to any of them. But my initial comment, which started all of this, was born out of observing how passionate we can get on here defending our points of view. Lots of great thinkers over the last several centuries have commented on why we do that.
