“How can we dominate our domination; how can we master our own mastery?” (tweet)
Like this question’s phrasing. Population explosion indicates a certain mastery, climate change however suggests limits to that mastery, is what I think of.
Would toss out that a beginning to” mastering our mastery” would involve acknowledging we’ve mastered just a small part of a larger thing to be mastered (e.g., we’ve mastered growth but not sustainable growth), or part of a thing which can’t ultimately be mastered (“God”, “ourselves”).
