The book was a great collection of articles from a radical libertarian perspective. Thought provoking and somewhat controversial (a pretty good argument, that I don't know if I agree with, arguing that libertarianism is actually the truest form of socialism is one such example). I totally intend on purchasing a hard cover copy for reference, even though the entire text is available free of charge on the Internet. Especially good is the final chapter on the environment. This is something that Libertarian environmentalists frequently struggle with, and I think many good solutions are presented, and beyond the cliche "the market will handle it" and "property rights will save the environment" [return][return]However, as I "read" the audio book, as with all audio books I have downloaded for free, they are worth what you pay for them. Reading the citations in line makes it nearly impossible to listen to at times, in addition the reader's voice is incredibly annoying. Its like listening to Charlie Brown's teacher read great literature. Its good, but it would be so much better if someone else did it.
