This address was intended to be and remains about global circulatory processes and the ways that human societies have sought to deploy, control, or regulate these processes. In this essay, I principally consider how nationalist ideologies regulate global circulatory processes. The parallel with the current COVID-19 crisis is evident, and my remarks do suggest some similarities. Although COVID-19 is not the topic I engage here, my theme alerts us to thinking methodologically about largely invisible or inconspicuous modes of circulation and their consequences, less dire but deeply transformative.
