In the preceding chapters, I examined four liabilities in the standard reading of Kant. As commentators continue to green the philosophical canon with figures as diverse as Confucius, Plato, Leibniz, Spinoza, Goethe, Heidegger, Nietzsche, Marx, Arendt, and Habermas, so also has it become apparent that a greener Kant is now possible. A greener Kant is also valuable, especially for rethinking the challenges of climate change. In Chapters 1 and 2, I showed why these liabilities and their attribution to Kant make sense: When Kant’s philosophy is limited to very specific texts from a single period in Kant’s intellectual career – the Groundwork, Critique of Pure Reason, and Critique of Practical Reason – red flags abound. And while I argued that strict Kant commentators such as Guyer, O’Neill, and Varden do a formidable job defending Kant in his letter, they fail in bringing his philosophy up to speed with issues regarding the climate crisis. Interpreters of Kant in spirit also do an admirable job.
