Family and friends of Hans Blumenberg have established a Blumenberg Society, and you can join. It costs money, and on this side of the Atlantic, you would have to go through a few hoops to pay the dues, because the organizers will not accept personal checks or credit cards. The membership form explains the details of using the host bank’s information to forward your payment.
As mentioned in an earlier post, a new English translation of Blumenberg, Rigorism of Truth, is just out from Cornell University Press, and Blumenberg’s book on lions comes out soon in English too, though the publication date has been moved forward for the past half a year. In the past week, it has now jumped from a March 2018 publication date to April.
