The two letters to the editor that follow reflect a kind of discourse that I would like to encourage for future issues of Advances in Nursing Science. Dr Margaret Newman and Dr Emiko Endo have both provided letters in response to the article by Yamashita and Tall that appeared in ANS 21:1, titled "A Commentary on Newman's Theory of Health as Expanding Consciousness." The perspectives that these scholars bring can enrich our understanding of complex concepts and theoretical ideas. I invite others to join this discourse, or to open further discussion around other articles that we publish in ANS.
