the honest math of a world that refuses to pick a side
means The quality of being blurry, indistinct, or imprecise — whether in an image, a thought, a boundary, or a degree of truth that sits somewhere between yes and no.
from From 'fuzz,' a word that surfaced in English around the 17th century with no clear pedigree — possibly imitative, possibly from Low German or Dutch 'fussig' meaning spongy or loose. It first described the soft, downy texture of things like lint, mold, and the fluff on a peach, then drifted naturally toward anything lacking sharp edges. The '-ness' simply turns the texture into a state of being, and the modern technical sense — fuzzy logic, fuzzy sets — borrows that same softness to name truths that won't snap cleanly into true or false.
