With most jointly authored books the process of hammering out an agreement between the co-authors is intransparent, except perhaps to the attentive reader who might notice breaks in style or inconsistencies in the argument. Reckwitz and Rosa have chosen a different, and novel, approach: they each offer texts under their own name. The reader is not entirely left to their own devices in spotting the similarities and differences between the two authors as these are thematized in a discussion at the end – a further innovation – in which they are interviewed by the philosopher Martin Bauer. Two books, as it were, for the price of one.
