Two Problems for the Political Inclusion of Animals

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT In recent years, the field of animal ethics has taken a political turn, with scholars arguing that sentient nonhuman animals should be included in the political sphere. This article explores two key challenges arising from this turn towards the political inclusion of animals: the Conflict Problem and the Numbers Problem.
