 The mainstream understanding of the current research into the obligations treatises seems to emphasize in different ways that according to the standard approach (exemplified here by Burley’s rules) the set of all answers will be consistent. Thus, it may seem reasonable to understand obligational disputations as a kind of consistency maintenance game. Given that in modern logic the concept of a possible world is often understood in terms of what a potentially infinite consistent set of sentences describes, the sequence of answers in an obligational disputation can perhaps be interpreted as an expanding description of a possible world.
