I’ve been reading through the two volumes of Rosenzweig’s letters and diary entries here and there for good while, but  in a footnote in the first chapter of Benjamin Pollock’s so far quite interesting Franz Rosenzweig and the Systematic Task of Philosophy I came across an something I haven’t yet seen.   As Pollock notes, Rosenzweig was rather unimpressed with the majority of the Neo-Kantians (except for Hermann Cohen, really), who he thought were simply confused about the relationship between a “system” and the task of philosophy.  Hence the need to return to the  approaches of German Idealism to get clear on the systematic task of philosophy. In this letter his ire is directed towards Rickert
