The writing of the Tractatus Ayyew: Earthen Ethics is the culmination of a decade long dialogue and friendship between Russell Maier and Banayan Angway (read the full story in the preface). The book is inspired by Banayan's research and articulation of the concept of Ayyew for the Cordillera Administrative Region DepEd Indigenous Knowledge curriculum¹ and their experience founding the Filipino ecobrick movement.²

The words of the Tractatus Ayyew are written by Russell with Banayan's oversight and review. The chapter format of prefaced ecological parables is inspired by the Igorot tradition of storytelling after the Bugnas festival feast.
