Kenneth Waltz's Kantian moral philosophy: ‘the virtues of anarchy’ reconsidered

Abstract Kenneth Waltz once stated, unequivocally, that, ‘I consider myself to be a Kantian, not a positivist’. I explain what Waltz might have meant by this, and how deep this professed Kantianism ran. Such is the depth of the engagement, I argue, that it is no exaggeration to claim that Waltz's political philosophy, his philosophy of history, his philosophy of science, his methodology, and his normative theory of anarchy are all broadly Kantian. Crucially, what Waltz meant by the ‘virtues of anarchy’, is best understood as an attempt to develop a regulative ideal, or an ‘organising principle’ of ‘practical reason’ that would guide diplomats in the nuclear age. Indeed, in his most contentious intervention in global public policy, Waltz deploys Kant to argue that horizontal nuclear spread, rather than the spread of democracy, would ensure the peaceful development of states. This anarchic nuclear peace would, he thought, be the means to achieve ‘perpetual pacification’. This revisionist reconstruction is the primary contribution of the paper. But through unsettling paradigmatic readings of ‘Waltzian IR theory’, the paper also presents an immanent critique of ‘the virtues of anarchy’ that contributes to a wider research project on the concept of anarchy and its emancipatory potential.
