 I'd like to talk about Man economy and state with power and market and that's a book that was republished by the Mises Institute. Initially there were two separate books Man economy and state and power and market because the second part power and market was much too radical. It suggested that we really did not need a government. It was a part of the book that was to talk about government intervention and so Rothbard in that part of the book suggested that in fact government intervened by the very fact of its existence because governments could not exist without taxation and as we know taxation is a violent intervention into the market. It's akin to robbery. Someone takes your money coercively. Whether that's whatever your ethical judgment on government taxation is the fact of the matter the economic fact of the matter is that it's a coercive exchange. You're forced to give your money up. In any case that's why the original publishers of Man economy and state cut out the last chapter and then that later became a separate book in 1970 that was issued. The Mises Institute a few years back then decided to issue a scholars edition of Man economy and state and in that they combined both books so that now it was the unified hole that Rothbard had initially envisioned. Now let me say a few other things about Man economy and state. I've called it before the book that saved economics before that book was written in 1962 before it was published in 1962. The Austrian economics had almost completely died out. There were a few Austrian economists who were writing in the 1950s. They tended to be students of Ludwig von Mises who was giving a seminar in at New York University in New York City and Rothbard was one of the attendees as was Israel Kursner and Henry Haslett and a number of other now famous Austrian economists but what occurred was that no one was listening to these people. There was just a small group. Mises was teaching them. He was keeping the ideas alive so Rothbard decided to write a text that would be accessible to college students. That was going to be Man economy and state but as he progressed in his writing he actually found that Mises had not covered all of the topics in economics in his huge treatise human action. There were many other things in human action like philosophy, comments and insights about culture, sociology and so on but the economics was there but it assumed that you knew a lot of economics to begin with. So what Rothbard set out to do was to develop economics from the simple fact that human beings act, that they start from purposes that they themselves know and they then use means to achieve these purposes in the most efficient manner. Rothbard spun out all of these implications of human action and what it showed really was that the most efficient form of the economy is one in which there is a completely free market with no government intervention, with no government disturbance or interference with people's free exchanges and what the book shows is really that what's called the market is not a thing but it's simply the network of all voluntary exchanges that we all make every day.
