Circumstantial and constitutive moral luck in Kant's moral philosophy

The received view of Kant’s moral philosophy is that it precludes all moral luck. But I offer a plausible interpretation according to which Kant embraces moral luck in circumstance and constitution. I interpret the unconditioned nature of transcendental freedom as a person’s ability to do the right thing no matter how she is inclined by her circumstantial and constitutive luck. I argue that various passages about degrees of difficulty relating to circumstantial and constitutive luck provide a reason to accept a pro-moral luck interpretation of Kant.
