Modus Vivendi Arrangements, Stability, and the All-Subjected Principle

Despite the importance of the requirement that all parties subject to a modus vivendi accept it, the philosophical basis of the all-subjected principle has been largely neglected in the realist literature on modus vivendi arrangements as responses to disagreements on issues of common concern. In this article, I argue that the inclusion of all-subjected parties should be understood as instrumental to justifying the presupposition that enough parties will have the motivation to comply with an arrangement that they grudgingly accept as a modus vivendi. I also argue that without accepting the democratic commitments implicit in the acceptance of the standard reading of the all-subjected principle, realist modus vivendi theorists should demonstrate that all those parties who are subjected to a modus vivendi arrangement have the capacity to voice their objection and to be heard for such a claim.
