Two threads run through this collection of 22 papers by students and colleagues of James D. McCawley. The first is a commitment to deep reflection on the direction of linguistic study, sometimes resulting in challenges to the writings of major figures or new appreciations, sometimes questioning our assumptions about the organization of linguistic information in the mind. The second thread is a shared sense of the requirements for the rigor of a good linguistic argument, that its presentation be thoroughgoing, straightforward and clearly made. There is a strong emphasis on testing the “party line” with the widest possible range of languages and the strongest possible set of linguistic tests. Demonstrating bugs and strategizing over the choice between competing analyses is not enough. The completion of an argument lies in constructing a better alternative.
