Chapter 7, the final substantive chapter, confronts the radical and ambitious nature of the proposals outlined in the book. Indeed, in light of its aim to outline a realistic utopia, this final chapter asks whether the prescriptions offered are indeed realistic, or whether they are impossible to achieve. This chapter offers some reasons to suggest that the proposals are possible, and provides a sketch of some of the necessary (but not sufficient) means by which a sentientist politics might be created and maintained. It argues that one crucial prerequisite of a sentientist political system is that it is underpinned by a civil society with ‘sentientist solidarity’; that is, a citizenry with feelings of shared affiliation with sentient non-human animals, as well as a commitment to the institutions designed for their protection.
