Thought and work on liberal peacebuilding have always been haunted with feelings of urgency and hysteria, as if the four horsemen of the apocalypse were about to arrive. The literature tends to think of peacebuilding as merely a project to avoid relapse into conflict by focusing on prevention, stabilization, or hard security measures. Even critical peace scholars have narrowed down peacebuilding excessively to mean little more than small, everyday peacebuilding. There is no enthusiasm for pointing toward newer ideals of peace after war, after the apocalypse. To this aim, this chapter engages with the work of sociologist, social reformer, feminist, and peace activist of the early twenty century, Jane Addams, who was the first to theorize what a positive peace may be. A positive peace, which was already emerging from the ashes of the First World War, would enlarge human relations, and would be heroic, courageous, and forceful, substituting the virtues of war. Her pragmatist work is useful to think of alternative imaginaries of the liberal peace in times in which imagination about peace and peacebuilding has dimmed.
