What are the boundaries of this potential revolution? Exploring the shape of Mahoney's scientific-constructivist social science

Jim Mahoney has written an opus magnum. The breadth, scope, and potential implications of the system of thought proposed by Mahoney are such that any attempt—or at least any attempt by me—to do justice to all important aspects of this book is, unavoidably, doomed to fail. I will necessarily have to be very selective and focus on those aspects that I feel reasonably competent. And, even more, rather than commenting or responding to some of Mahoney’s main arguments, I will mostly ask questions of clarification. These will be genuine questions, not rhetorical ones. I am curious to hear Mahoney’s answers because—so my hope—those answers will further sharpen the boundaries of the revolution of the social science (singular!) that Mahoney is arguing for. I shall also disclose that I not only find this book mind-blowing and horizon-widening, but also largely agree with its main gist.
