Visualize a world where people are fully free to pursue their life-serving values and to trade with one another by mutual consent to mutual benefit. Imagine that most people in this world see such self-interested actions as morally good. Envision yourself, your friends, and your family consequently flourishing by orders of magnitude greater than you do today. Is such a world possible? It is. And it belongs to those who are willing to fight for it. In this talk, Craig Biddle will argue that in order to move ourselves and the culture toward this ideal, we must take a scientific approach. We must understand and embrace the fact that the principles of freedom and flourishing, like those of physics and engineering, are matters of observation and logic. And we must learn to communicate these truths to others with the same clarity we would expect from a competent engineer explaining how a lever works or why a building stands.
