Abstract

In "Kant on Freedom and Rational Agency", I aim to give a comprehensive interpretation and a qualified defense of Kant’s doctrine of freedom as a systematic conception of rational agency. Although my book follows Kant in focusing on the idea of free will as a condition of moral agency, it denies that moral freedom of will is the only relevant (transcendental) type of freedom. Human beings also exercise absolute freedom of thought (intellectual autonomy) in their theoretical cognition. Moreover, our creation and appreciation of beauty requires our freedom of imagination. I consider these three varieties of free agency both in their own rights and in their systematic connections, by examining how they differ from and yet relate to each other. On this basis, my interpretation shows that and why for Kant transcendental freedom is the proper anchor ("cardinal point") of all meaningful, rational human activity: our moral efforts to become more virtuous and to make the world a better place; our theoretical efforts to understand, explain and predict the world; and our aesthetic engagement with the world of beauty, both artistic and natural. Additionally, "Kant on Freedom and Rational Agency" illuminates Kant's intricate, multifaceted account by considering the various metaphysical, semantic, epistemological and normative dimensions of Kantian freedom and by revealing their systematic interconnections. One significant benefit of tracing these links is that by doing so we can arrive at a charitable view of how Kant seeks to justify the belief in moral freedom of will. For many commentators, Kant's appeal to a moral ‘fact of reason’ as our basis for believing in supersensible free will is an abject philosophical failure or a lapse into dogmatic rationalism. By contrast, I show that Kant justifies our belief in free will through a rather powerful, two-pronged argumentative strategy. First, he constructs a practical-moral proof of free will via the fact of reason doctrine. Second, he provides a theoretical defense of this moral proof against challenges arising from a naturalistic worldview. The linchpin of this defense is his argument that naturalistic cognizers must presuppose their epistemic freedom of thought as a necessary condition of all objective theoretical (including naturalistic) cognition. Since epistemic freedom of thought and moral freedom of will are both species of transcendental freedom, naturalists cannot (coherently) debunk our practical self-conception as transcendentally free moral agents. The appeal to epistemic freedom of thought provides no positive grounds for believing in a free moral will; but it shields our moral self-awareness (which does provide such grounds) against its most prominent detractors. This defense strategy (among other aspects of Kant’s view that I examine in my book) shows that a significant part of Kant’s legacy is his abiding potential to challenge and provide alternatives to a naturalistic philosophical worldview (held by the “defender of an omnipotent nature”) according to which the mechanistic order of nature engulfs all metaphysical reality and (thereby) our entire humanity.
