While the field of environmental justice studies has produced robust theoretical and methodological advances and tools for exploring the intersections among ecological harms and social inequalities, there are numerous limitations within that body of literature. Critical environmental justice is a framework proposed to address some of those gaps, and is applied in this chapter to the case of the Israel-Palestinian conflict to illuminate some ways through which scholars can 1) expand the range of social categories considered in EJ studies, 2) employ and pursue a multiscalar analysis of EJ conflicts, 3) interrogate the logic of dominance and hierarchy that pervade much of EJ scholarship and politics, and 4) introduce the idea of indispensability—a form of ethical political ecology—to address narratives and practices of expendability that underlie many EJ conflicts.

This chapter demonstrates how thinking about truthmakers can bring some clarity to the ongoing debate concerning the ontological status of mathematical entities, and advances one position on the topic. It begins with what is nowadays the most familiar argument in the ontology of mathematics: the indispensability argument. Close inspection of it reveals that the notion of truthmaking is indeed playing a role, and that by thinking about indispensability and truthmaking in tandem, both ideas emerge with greater clarity. Focusing on indispensability will shed light on what the ontological stakes are in the overall debate, so the second section presents what is seen to be the most tenable ontological positions. It then offers a personal (rather deflationary) contribution to the truthmaking question about mathematics, and concludes by comparing and contrasting that view with a recent brand of mathematical trivialism.
