Is there a right of freedom of expression?

Larry Alexander offers a skeptical appraisal of the claim that freedom of expression is a human right. He examines the various contexts in which a right to freedom of expression might be asserted and concludes that it cannot be supported in any of these contexts. Alexander argues that the legal protection affording freedom of expression is definitely of value, although the form such protection takes will vary with historical and cultural circumstances--and, ultimately, is not a matter of human rights.
