Responding to the commentaries of Pellegrini and Leavitt (this issue), I focus my discussion on matters of form in relation to psychoanalytic writing and theory. Using Donna Haraway’s model for “thinking-with,” cat’s cradle, as a formal and theoretical device, I use the physical space of the page to play a textual game of cat’s cradle with Pellegrini and Leavitt (Haraway, 2016). Thinking-with Pellegrini and Leavitt, I engage with and extend their discussions of the troubled history, socio-political implications, and potential transformations of form in psychoanalysis, particularly as it relates to my use of ‘radical openness.’
