The spread of vaccine misinformation may contribute to vaccine refusal/hesitancy and consequent harms. Nonetheless, censorship is often rejected on the grounds of free expression. This article examines John Stuart Mill’s influential defence of free expression but finds that his arguments for freedom apply only to normal, reasonably favourable circumstances. In other cases, it may be permissible to restrict freedom, including freedom of speech. Thus, while Mill would ordinarily defend the right to express false views, such as that vaccines cause autism, (...) he might have accepted restrictions on anti-vaccine misinformation during the present pandemic. This illustrates that even the staunchest defenders of free speech can permit temporary restrictions in exceptional circumstances. (shrink)

In this paper I will argue that Mill employs a tacit concept of competence in On Liberty. I will focus on the role of truth and individuality in On Liberty. Competence is a precondition for individuality, and as such, it is a threshold concept: those above the threshold are sensitive to rational argument and should be free to pursue happiness in their own way (because they are guided by the truth), whereas those who fail to meet this threshold should be (...) educated and paternalistically be kept out of harm's way until they are able to find the truth for and by themselves.
