This is a paperback reprint of a book published in 1989.

In this comprehensive treatise Greenawalt explores the three-way relationship between the idea of freedom of speech, the law of crimes, and the many uses of language. He begins by considering free speech as a political principle, and after a thorough and incisive analysis of the justifications commonly advanced for freedom of speech, looks at the kinds of communications to which the principle of free speech applies. He then turns to an examination of communications for which criminal liability is fixed. Focusing on threats and solicitations to crime, he attempts to determine whether liability for such communications seriously conflicts with freedom of speech. He then goes on to develop the significance of his conclusions for American constitutional law.
