 The audience as well is part of the field shared by words, speakers, and things. Different expressions are used in addressing different people. For most Japanese Buddhist philosophies, ordinary language is always heuristic expression (hōben; Sankrit: upāya) in that words are directed to someone to lead them to some insight. So words are always being adjusted. Mori Arimasa (1911–1976) noted that Japanese syntax demands multiple levels of formality and politeness indicating the social space shared by speaker and listener. That characteristic, he claims, gives the language an inherently second-person, rather than impersonal, third-person feel (JPS 1047–52).
