A City Guide To Zibo for Nor does one’s exercise of power always constitute a threat or diminution of another’s power. Many theorists, including Hobbes and Weber, assume that the exercise of power is a zero-sum game. They believe that any increase in the power held by one person means a decrease in power held by another, with the net sum always being zero. Other political theorists, such as Hannah Arendt, insist that cooperative activity”acting in concert”constitutes an exercise of power wherein influence is reciprocally exercised and interests are mutually served. As social order is established, mutual influence grows, and so does power. While this growth of power is seldom shared in an egalitarian manner, it certainly need not be zero-sum. Cooperation begets a positive-sum game of power. A City Guide To Zibo 2016.
