Abstract
As a rule, there is nothing in the words themselves to mark off metaphors from literal language. If a boundary could somehow be drawn, it would be in constant need of re‐adjustment as metaphors become entrenched, idiomatic, and finally literal, and literal phrases are put to figurative or hyperbolic, and then metaphorical uses. Further, there is no algorithmic recovery of the intended meaning of a metaphor from the meanings of its components, no function that takes literal meanings as its arguments and has metaphorical meaning as its output. That is, metaphors are syntactically invisible, pragmatically unstable, and semantically under‐determined. Their creation, use, and interpretation are almost impenetrable mysteries. As if to spite semantic theorists, they are also linguistic commonplaces, present in every kind of discourse. The discourse of philosophy is no exception to this rule, availing itself of the various stylistic, heuristic, and explanatory roles metaphors can play. Philosophy also produces metaphors of another sort, metaphors that differ in important ways from the metaphors of art and literature, as well as the metaphors of the natural and social sciences. These “grand“ metaphors are lasting monuments to the triumphs of philosophical discourse, even as they are also testimony to the failures of philosophical theorizing. This is because philosophy’s grand metaphors were never intended that way. They are better read as structural hypotheses that have become metaphors only after failing as literal truths. Ironically, it is precisely as metaphors that these images are integrated into our ways of thinking. In the end, thought itself is re‐structured, and these failures as descriptive truths succeed in becoming “constitutive truths” of a new reality.
