Agree. I wonder if aphantasia forces you to construct a richer and more abstract “internal grammar” when you can’t rely on visual imagery. For mathematicians that aren’t aphantasic I wonder what goes on in your mind when you imagine a “compact set.” To me I have a distinct object that presents “compactness” in the mathematical sense in my brain. It’s not associated with any other sense (words, hearing) it just “is” the concept of compactness. It’s not even related to the formal definition of a compact set. It’s more like a “feeling” of convergence in the limit (if that makes sense). For folks heavily reliant on visual imagery would they have instead a visual representation of “compactness” that’s constructed in the visual sense rather than an abstract idea.
