 Mill takes the three cases to be exhaustive: whatever an opinion’s status in terms of truth, then, its suppression would be epistemically damaging (Skorupski 1989: 377–83). The argument’s focus on truth, of course, limits the scope of the argument. Though there may be arguments establishing that forms of communication which do not have truth as their goal—poetry, art, music—should be free from interference, these are not to be found in chapter 2, but later in On Liberty.
