Book excerpt: Some sentences in natural languages like English have multiple meanings. Steinhart (William Paterson U. of New Jersey) divides the meanings into literal and metaphorical, denies that they are the same, and denies that the metaphorical function is necessarily false or necessarily true. He argues that most metaphors are based on analogies, which he defines as the relative structural indiscernibility of parts of worlds, and that a metaphor is true for a particular world if and only if certain parts of that world are relatively structurally indiscernible, that is, are analogous. c.
