Description:Even today, prominent voices accuse Kant's philosophy of implying the individual to be subjectivist and monologic. However nothing could actually be further removed from Kant's position than subjectivism of this kind. Kant's reason is public through and through. Its very existence depends on public argumentation. This work looks at ""public reason"" in the three critiques and other works and shows how closely Kant's theoretical philosophy is bound up with his political writings.
