スタンリー・フィッシュ
A collection of essays. The essay with the same title as the book and an additional essay, "Jerry Falwell's Mother" are insightful regarding free speech issues. In particular, if -- as Fish notes -- one has some answer in mind to the question "what is free speech good for?" along the lines of "in the free and open clash of viewpoints the truth can more readily be known" then it is the height of stupidity to defend deliberate malicious libel in the name of "free speech."
