Mill thinks our attitudes should be held in a way that’s active and ‘alive’. He believes attitudes that lack these qualities—those held dogmatically, or in unreflective conformity—are inimical to our well-being. This claim then serves as a premiss in his argument for overarching principles of liberty. He argues that attitudinal vitality, in the relevant sense, relies upon people experiencing attitudinal conflict, and that this necessitates a prioritization of personal liberties. I argue that, pace Mill, contestation isn’t required for attitudinal vitality. (...) I describe one species of attitudinal vitality that isn’t reliant upon conflict. (shrink)
