Words refer to objects, and they don’t actually live in our brains – only experience does, and we use words to convey our experiences. Or so is the claim. For instance: “What is an angel but a juggling of past experience: beautiful body, plus wings, as in a dream? What is dark matter if not a piece needed to complete a puzzle, a theory, made up of endless complex objects in the world? Sometimes, the imaginary object is a reshuffling of real objects and thus it is real in its own way; sometimes, it is nothing.”
