Ludwig von Mises, the author of such classics as 'Socialism and Human Action' is universally acknowledged as one of the most important classical liberals and economists of the twentieth century. In 1934, he left his native Austria in fear of the Nazis, who seized all his papers in 1938 in Vienna and Mises thought, destroyed them. But the papers were not destroyed. In 1996, Richard and Anna Ebeling discovered the papers in an archive in Moscow. This is the second volume in the Selected Writing of Ludwig von Mises series.
