This unusual book takes the form of a dialogue between a linguist and another scientist. The dialogue takes place over six days, with each day devoted to a particular topic - and the ensuing digressions. The role of the linguist is to present the fundamentals of the minimalist program of contemporary generative grammar. Although the linguist is a voice for Noam Chomsky's ideas, he is not intended to be a portrait of Chomsky himself.

The other scientist functions as a kind of devil's advocate, making the arguments that linguists tend to face from those in the "harder" sciences. In addition to the device of the dialogue, the author employs a myriad of graphics - everything from classical paintings to contemporary cartoons.
