Abstract: In her Keynote Address at the October, 12, 2012 Symposium, Filling Power Vacuums in the New Global Legal Order, Anne-Marie Slaughter describes the concepts of “power over” and “power with” in the global world of law. Power over is the ability to achieve the outcomes you want by commanding or manipulating others. Power with is the ability to mobilize people to do things. In the globalized world, power operates much more through power with than through power over. In contrast to the hierarchical power of national governments, globally it is more important to be central in the horizontal system of multiple sovereigns. This Address illustrates different examples of power over and power with. It concludes that in this globalized world, lawyers are ideally trained and positioned to exercise power.
