The genetic self, according to Wolpe, is an answer to the postmodern self. The genetic self is the essential self, “written into the genome” . However, Jewish selfhood, for Wolpe, stands in healthy contrast to this strong genetic essentialism. “Jews have always understood that identity is chosen, is to some degree the product of moral choice” .
Have Jews always understood identity as something that is chosen? Have Jews always come down on the side of culture rather than biology? And does that really hold true today? Do Jews maintain a healthy suspicion or even repudiation of genetic essentialism? Or do many of them embrace genetics as a true and meaningful way of discovering, or perhaps constructing, a Jewish identity? What is it about “geneticism” that is so attractive? What needs does it fill? And how do we square this recent Jewish enthusiasm for geneticism with the history of racial, genetic, and eugenic thinking that played such a crucial role in modern anti-Semitism, Nazism, and the Holocaust?
