There's a lot of talk being thrown about these days equating dissent with treason. Much of it, of course, is put out by talking-head commentators who have something to sell – a book, or a radio or television program. Opposing that point of view is a book that just crossed my desk. "Dissent in America: The Voices That Shaped a Nation" (Pearson Longman, 788 pages, $35), by Ralph F. Young, a senior lecturer in Temple University's department of history, includes writings from some of the most distinguished names in American history.
