Language and Problems of Knowledgeis Noam Chomsky's most accessible statement on the nature, origins, and current concerns of the field of linguistics. He frames the lectures with four fundamental questions: What do we know when we are able to speak and understand a language? How is this knowledge acquired? How do we use this knowledge? What are the physical mechanisms involved in the representation, acquisition, and use of this knowledge?

Starting from basic concepts, Chomsky sketches the present state of our answers to these questions and offers prospects for future research. Much of the discussion revolves around our understanding of basic human nature (that we are unique in being able to produce a rich, highly articulated, and complex language on the basis of quite rudimentary data), and it is here that Chomsky's ideas on language relate to his ideas on politics.

The initial versions of these lectures were given at the Universidad Centroamericana in Managua, Nicaragua, in March 1986. A parallel set of lectures on contemporary political issues given at the same time has been published by South End Press under the title On Power and Ideology: The Managua Lectures.
