Freedom of Speech is held to be one of the most important values in contemporary political life. Although freedom of speech has attracted many supporters, many of the philosophical issues concerning it remain unexplored. This collection of essays, first discussed at the 1985 Conference of the UK Association of Legal and Social Philosophy, sets out to examine the values which support freedom of speech and also the limits which can be rightly made on its exercise. This book will be of major interest not only to political and legal philosophers but also to all those with interest in the nature of the media in modern society.
