Abstract
The world order envisioned in Mario Bunge’s political philosophy is one that combines a flowering and sustainable industrial society, a clean environment, full social justice, full realization of individual potential, and perpetuation of the human lineage. The problem is that these objectives are not jointly satisfiable, and more than one is individually impossible. Socialism is the hero and the villain of the piece. Along the way to its conclusion new conceptions of politics, socialism, capitalism, and today’s social democracy are proposed.
