“…Although Piaget and Gödel almost certainly met at the Institute for Advanced Study, when Piaget was a visiting fellow there in 1954, there is no correspondence between them held in the accessible collections at any of the archives we consulted. (This is not in itself especially meaningful, though: the majority of the collection held by the Piaget Archives is unprocessed and not available for consultation; Burman, 2013a, although things are indeed expected to open up starting in 2018; M. J. Ratcliff, personal communication, January 24, 2016.) As a result, we can only trace the changes in the larger discourse in which they both participated: preparatory spadework, in anticipation of future in-depth archival excavations (e.g., Heinzmann, Trognon, & Tremblay, 2014; Ratcliff & Burman, 2015).…”
