In recent years, there has been tremendous interest in the contributions of the great German philosopher Immanuel Kant to on-going debates about the appropriate nature of international justice and law. The end of the Cold War, for example, seemed to bring with it promises of greater international cooperation of the kind envisaged by Kant. Furthermore, those interested in the more explicitly moral aspects and potentialities of international law, such as those regarding human rights protection, have looked to Kant for comfort and inspiration in the face of strong pressures from doctrines dismissive of such aspects, such as law-and-economics and the statist strictures of realpolitik.
There has, however, been widespread scholarly disagreement over Kant’s precise heritage in this regard: some, for instance, have found in Kant’s international writings a harbinger of world government while others have criticized Kant for faihng to specify any concrete powers for his fabled cosmopolitan federation; some have accused Kant of sacrificing his exalted moral principles on the dubious altar of state-centred expediency while others dismiss Kant as one of the most naively optimistic, and hopelessly moralistic, international thinkers ever; and, finally, some have accused Kant of glorifying the resort to warfare while others insist that Kant actually advocated “an extreme pacifism.” There is, in short, a ferocious and complex debate regarding which set of ideas can properly be called the “Kantian” view of these foremost issues of international law and what, if any, value can be attached to it.
