We're taught to think we understand. But do we? Language offers a black-and-white feeling we're clearly understanding something perfectly. That's an illusion, reinforced by years of approval at school. Language, which science depends on, is a visual art--symbols on paper. As with any visual art, the structured symbols together really convey very little, even if we agree it means something important. Pages, books, libraries, institutions, frames around frames around frames of ambiguity, approximation and interpretation.
