"The theme of this book is encapsulated in its portrayal of one of my heroes—or, I should say, my newest hero, since I had no knowledge of him before reading Blumenthal's work: his name is Yeshayahu Leibowitz. The Israeli polymath, who fled Germany in 1933 and emigrated to Palestine where he taught brain physiology at Tel Aviv University, starting teaching philosophy at the age of 72 (!), was an Orthodox Jewish scholar who edited the Encyclopedia Hebraica—and a hardcore libertarian only a little less radical than Murray Rothbard, whom he resembles in style and mannerisms to an amazing degree."
