Message: Hi Bob,
I’ve had the pleasure of taking many of your on-line classes with the Mises Institute over the years (I can’t believe it’s actually been years!). In my Public Choice Theory class, we finish the semester with your Chaos Theory book, to illustrate the extremes to which we can push the idea of minimizing the role of the state. On the final exam, which we just finished, I have an essay question on your notion of a private defense system and I thought I’d share with you the opening paragraph one of my students wrote in addressing this topic:
“When I first read about Murphy’s idea of a private defense system, I was a little skeptical because I did not understand it. But now that I do understand it, I could advocate (for) it. The idea of having a privatized defense system is really interesting. The fact that it would be through firms and not the government is interesting.”
Here is the PDF of my pamphlet Chaos Theory. But, before you read that, I recommend these two articles I did for Mises.org which will provide a better foundation for the mechanisms I discuss in the pamphlet.
