For a New Liberty: The Libertarian Manifesto by Murray N. Rothbard
An absolutely awesome book. If you are interested in liberty, this is, in my opinion, the most important book to read.
I think Lew Rockwell, who I recently had the pleasure to meet at the Ludwig von Mises Institute, says it best about this book:
Once you are exposed to the complete picture — and For a New Liberty has been the leading means of exposure for more than a quarter of a century — you cannot forget it. It becomes the indispensable lens through which we can see events in the real world with the greatest possible clarity. … Its logical and moral consistency, together with its empirical explanatory muscle, represents a threat to any intellectual vision that sets out to use the state to refashion the world according to some pre-programmed plan. And to the same extent it impresses the reader with a hopeful vision of what might be. … He never talks down to his readers but always with clarity. Rothbard speaks for himself. … The reader will discover on his or her own that every page exudes energy and passion, that the logic of his argument is impossibly compelling, and that the intellectual fire that inspired this work burns as bright now as it did all those years ago.
And finally, from Lew again:
The book is still regarded as “dangerous” precisely because, once the exposure to Rothbardianism takes place, no other book on politics, economics, or sociology can be read the same way again. What was once a commercial phenomenon has truly become a classical statement that I predict will be read for generations to come.
This book is available for purchase at the Mises Institute at http://mises.org. It may be read in its entirety from that site, and an audio recording is available there as well.
