Comments by Jo van den Berghe on moments within PhDs when knowledge is produced beyond the terms or expectations of the project from the outset. The search that produces new insights. This was a crucial intervention. Christoph Heinemann’s analogy of the work of the designer/thinker with St Thomas touching the wound of Christ. Ana Telles’s contribution to the discussion of the copy in which she spoke of its importance in relation to traditions in music. All of these led me to think that the specific moments pertinent to design thought and action are in themselves necessarily illustrated as knowledge.
