Abstract

The primary intention of Ren and Canavero's article (2017) is to respond to various criticisms raised by their proposal of the head anastomosis venture (HEAVEN) procedure. Before we launch a deeper analysis of Ren and Canavero's article, I would like to draw attention to a sentence, “Unfortunately, humility is not a part of medical lore,” where they refer to the arrogance and unsuccessfulness of medical science to recognize the importance and breakthrough of the HEAVEN procedure. Interestingly, with this repeated citation, they acknowledge a familiar criticism of medical lore, so that we would expect that they provide a good example of the appreciation of humility in their present article.
