How any human being ever has had the impudence to speak against the right to speak, is beyond the power of my imagination. Here is a man who speaks-who exercises a right that he, by his speech, denies. Can liberty go further than that? Is there any toleration possible beyond the liberty to speak against liberty-the real believer in free speech allowing others to speak against the right to speak?
