Opening with a selective account of a century's work in the philosophy of meaning, from Frege and Wittgenstein to the late twentieth century, the book engages first with the nuts and bolts of sentence-construction: predicates and the copula, quantifiers, names, existence treated as a second-level predicate, and adverbial modification. The following five chapters then treat of definition and (as dreamt of by Leibniz and others) the terminus of semantic analysis; the idea of natural languages as real things with a history; the idea of truth conceived as correlative with inquiry (C. S. Peirce) and, finally, the properties we look for in truth itself--the marks, as Frege or Leibniz might have said, of the concept true.
