<p>In this timely book, the first comprehensive study of the modern American public intellectual--that individual who speaks to the public on issues of political or ideological moment--Richard Posner charts the decline of a venerable institution that included worthies from Socrates to John Dewey.</p><p>With the rapid growth of the media in recent years, highly visible forums for discussion have multiplied, while greater academic specialization has yielded a growing number of narrowly trained scholars. Posner tracks these two trends to their inevitable intersection: a proliferation of modern academics commenting on topics outside their ken. The resulting scene--one of off-the-cuff pronouncements, erroneous predictions, and ignorant policy proposals--compares poorly with the performance of earlier public intellectuals, largely nonacademics whose erudition and breadth of knowledge were well suited to public discourse.</p><p>Leveling a balanced attack on liberal and conservative pundits alike, Posner describes the styles and genres, constraints and incentives, of the activity of public intellectuals. He identifies a market for this activity--one with recognizable patterns and conventions but an absence of quality controls. And he offers modest proposals for improving the performance of this market--and the quality of public discussion in America today.</p><p>This paperback edition contains a new preface and and a new epilogue.</p>
