 Mill’s claim that On Liberty presents “one very simple principle”—is “a kind of philosophic text-book of a single truth”—perhaps belies the fact that there are many distinct arguments and conclusions drawn throughout the text (Liberty, XVIII: 223; Autobiography, I: 259). Mill employs different strategies to argue for freedom of thought and discussion, freedom of character, and freedom of action—and although of course such arguments overlap, they must be carefully unpicked if we are to appreciate their strengths and weaknesses. In this section, we will consider the argument for freedom of speech, turning, in the next section, to his case for freedom of character and action more broadly.
