Ansgar Martinsâs The Migration of Metaphysics into the Realm of the Profane is the first book-length study focusing on Adornoâs idiosyncratic appropriation of Jewish mysticism in the light of his relationship to Gershom Scholem and their shared intellectual contexts. Rather than merely posit vague associative connections, as previous authors have often done, Martinsâs close reading of specific references in published and private texts alike allows him to highlight both commonalities and differences between Adornoâs and Scholemâs understanding of Kabbalistic tropes and the issue of metaphysics in the modern world, and to demonstrate the extent to which similarities resulted from mutual and/or third-party influences (especially Benjamin). Martins throws the specifics of their respective idiosyncratic appropriations of (Jewish) tradition into sharp relief.
