From your perspective it isn’t. “Newton would disagree!“ Sorry, had to (ducks).But that is an empty endeavor. Human brains interpret their experience in three spatial dimensions. We use spatial references because that's how we're designed (whether or not it's accurate is a different issue). Great! We already know this. We already know that our symbols are embedded in the spatial scaffolding of our experience.
Are you suggesting that we cannot think abstractly, that we are incapable of conceiving without spatial reference? If so, argue that. Otherwise, recognize the difference between the necessarily spatial aspect of our communication and the abstract ideas contained therein, and get over the "braces have spatial dimensionality" schtick.
Mapping is one modality of learning. But is it a fundamental aspect of the universe or just a peculiarity of certain biological organisms on Earth? This is why I dislike the human-centric approach, it is far too easy to think "this is the way we do it, therefore it must the only way it can be done".
Information is not a geometric object. We apply geometric concepts to physical space to help us reason about physical space. The geometry of space is a model of space, it is not space itself.
We don’t know what information is until we make associations with physical space and objects as a child.
We must start there: literally 3 y/o playing with physical space blocks.
Yes, we are incapable of conceiving without spatial reference!
