Leibniz provides a roadmap for the purpose and role of humankind. If the purpose and role of humankind is not understood, then policy cannot be formulated effectively. We would be left with what we have today - government for private finance, with the future of humankind a secondary consideration at best. These essays from Leibniz are input for: - You who are concerned about the direction of the world; - Students of political science, economics, political economy, history, philosophy and theology; - Would-be politicians and statesmen unhappy with the direction and decisions of the current political elite; and - Professional policymaking circles to provide structure and direction to fulfil your responsibilities to the public. Gottfried Wilhelm Leibniz conceived the idea of the modern nation state, the Western conception of progress, and the concept of human power. Leibniz was a jurist, diplomat and peacemaker, and was critical in the discovery of steam power and generalizing the steam power to more intensive forms of power. Citizens, policymakers, jurists and lawmakers need a refresh and Leibniz gives us the direction and framework we need to refresh policymaking principles and substance at the national and international levels.
