Chapter 2 continues the thread from Chapter 1, moving from objections against Kant in animal ethics to broader concerns in environmental philosophy. I begin with problematic passages from Kant’s critical texts such as the Groundwork for the Metaphysics of Morals and the Critique of Pure Reason. While Kant does not discuss the environment, the standard interpretation of Kant suggests that nature has no intrinsic value and that environments are of mere instrumental worth. Environmental philosophers are warranted to suspect that Kant’s critical philosophy may be a nonstarter given its apparent dualism and anthropocentrism. Next, I examine three camps of Kant defenders who challenge these suspicions. Some commentators defend Kant’s system, others modernize him, and some synthesize Kant with other philosophers such as Aristotle. I assess the merits of their arguments, ultimately recommending a move beyond the standard reading to address the climate crisis.
