John Stuart Mill's Passage on Pimps and the Limits on Free Speech

Abstract Mill didn't resolve this puzzle: if prostitution must be tolerated according to his principle of liberty as it doesn't non-consensually harm others, why punish the accessory – the pimp? Yet in On Liberty's passage on pimps (CW 18:296–7) Mill seriously considers restricting pimps’ speech for reasons other than preventing harm: pimps’ speech undermines decisional autonomy for purposes the state regards as immoral, and in response the state may use coercion to counteract such immoral influences. In light of this, I argue that we need to rethink the standard view that Mill opposes restrictions on speech that does not harm others.
