PositiveThe Open Letters ReviewIt may be difficult for In Search of Isaiah Berlin to find a general audience. The author’s self-described \'pedantry\' is at times on full display as he reproduces pages of letters between himself and Berlin, clarifying a recondite point on cultural pluralism or negative liberty. Undoubtedly specialists, or those quite familiar with the writings of Isaiah Berlin or this unusual four-decade editorial relationship, will find the work of most interest. Nevertheless, Henry Hardy has produced a capstone to a remarkable story of letters, a Boswellian tale, a 40-year literary adventure.
