Natural vs Conventional Naming

When we call a horse a "horse," does the word somehow fit the animal's true nature, or is it merely a label we collectively agreed upon? In Plato's Cratylus, one side argues names are correct by nature, encoding the essence of what they name, while the other insists they are pure convention, assigned by custom and human accord. The stakes are high: if names mirror reality, language might be a path to knowledge; if they are arbitrary, we must look past words to the things themselves. Aristotle settled the matter for centuries by ruling that names signify by convention, while Epicurus offered a third route in which language begins naturally before being refined by agreement.
