My friend Jeff Hodges, the Gypsy Scholar, posts thoughtfully on the topic of free speech. He concludes: "Support free speech. Consistently."

There are two issues here that need to be distinguished. One concerns the consistency of application of a free speech principle, whatever principle we decide upon. To apply a principle consistently is to apply it equally to all like cases. Suppose the principle agreed upon allows the mocking of religious figures and their religions. It would then be inconsistent in point of application to allow the mocking of Islam but not the mocking of Judaism, or vice versa. So I agree with Dr. Hodges that free speech should be supported consistently if what that means is that the principle of free speech embraced ought to be applied equally to all like cases.
One issue, then, concerns consistency of application of a free speech principle. The other concerns the principle itself, its content and coverage. One could construe the injunction to support free speech consistently to mean that all types of speech should be allowed, that freedom of expression ought to extend to every type of expression. Or one could take the view that some types of expression ought not be allowed.
It is obvious that one who denies that freedom of expression extends to every type of expression can nonetheless support free speech consistently in the sense that he applies his principle equally to all like cases.
Now I will state my view. I support consistency of application of any free speech principle we adopt. But I find the notion that free speech, or free expression generally, ought to extend to every type of expression to be extremely dubious and in need of very serious examination. And I of course invoke my own right to free expression in pursuit of this politically incorrect question.
In this post I will consider only the case of lying. One has the right to publish but not the right to lie. To lie is to state a falsehood with the intention to deceive. Suppose David Irving is lying about the Holocaust. Why should he have the right to propagate his lies? Why should freedom of expression be taken to include freedom to express lies?
I bring up Irving only as an example. I am interested mainly in the principle, not in this case. And of course there is a serious question about how one could know that a person is lying. Essential to a lie is the intention to deceive; but how could one know what a person's intentions are? But suppose one knows that a person is lying. My claim is then that the person's lies ought not count as protected: there is no moral right to lie derivable from the right to free speech. Why not?
Lies ought not be protected since lies are violations of truth, and thus violations of that which makes free speech valuable in the first place. Free expression is valuable, even when it is upsetting and offensive to many, because it is conducive to the discovery of truth and thus conducive to enlightement and progress. The propagation of lies, however, impedes the discovery and dissemination of truth. It is an offense against truth. As such, it is an offense against the very thing for the sake of which we value free speech.
If we recognize a right to propagate lies as derivable from the right to free expression, then we assume the correlative duty not to interfere with the liar's propagation of falsehoods. But a duty to not interfere with the propagation of lies would conflict with our duty to respect truth -- a duty which is at the root of our toleration of free speech even when this speech is contentious and offensive to many.
My argument, then, is that it it incoherent to suppose that the right to free expression extends to every type of expression. For if it has this maximal extension, then it extends to lying. But if a right to lie is derivable from the right to free expression, then so is the obligation to tolerate lying. But any such obligation would conflict with the duty to respect truth -- which duty is at the root of our argument for tolerating free expression even when it is deeply upsetting and offensive to many people.
