IV.l Neo-Realism and the 'Scientification'158 of International Political Theory Whereas the English School proponents and their idea of an international society struggled with the question of what principles constitute and how to construct cooperation among states and finally failed in envisioning state-transcending, universal notions (as discussed in the previous chapter159), mainstream inter-national political theory in the twentieth century epitomized in neo-realism (or 'structural realism' as Waltz initially termed it) and neo-liberalism abandoned the idea of unity among states. Particularism triumphs, and both the ontology and the epistemology of twentieth-century IR mainstream solidify and lift the particularistic entity of the nation state as ultimate reference for political theory and practice. Ontologically, this enhancement of particularism manifests in the notions of nationalism, patriotism, and the 'national interest'; epis-temologically, the particularizing neo-realist/neo-liberal assumption of ■anarchy' and the confusion between an analytical and normative dimension of political theorizing, based on the self-belief of nonnormative theorizing and the scientification of international political theory according to a natural science model - or, to put it differently, the reification of politics - are liable for the 'triumph of particularism'. This ontological and epistemological abandonment of unity (see below Chapter IV.1.1) results in a theoretical logic of the inevitability of conflict and war among states ^ee below Chapter IV.l.2). War and conflict indeed come to be seen as the normality of inter-national politics; the Clausewitzian dictum of war as a continuation of politics becomes redeemed and axiomized in the theoretical mainstream of twentieth-century IR. The particularistic dogma does not allow any other conclusions, and conceptualizations of inter-national politics following this dogma are restricted to engineering mechanisms to mitigate the circumstances under which war might break out, they cannot, however, move beyond the intrinsic 'reality' of war and conflict inherent in its solipsistic theorizing. 197 198 A History of International Political Theory ii Neo-Realism 199 1. Solipsistic ontology and epistemology The ontological notions of nationalism, particularism, and 'national interest' stand at the beginning of Waltz's oeuvre theorizing international pol- j itics in Man, the State and War (1954). In this early work, Waltz discusses ; different authors from the history of political thought. It is noteworthy \ that Waltz understood himself (still) as a 'realist' when he wrote Man, the & State and War. However, analyzing especially his interpretation of Rousseau t reveals a coherent line of thought throughout his oeuvre which reaches « from this earlier work into Theory of International Politics (1979). Waltz might not have been fully conscious of this coherency, and writing in the 1950s J he certainly did not arrange and coin his later arguments. Nevertheless, this 13 continuity exposes his (and neo-realism's) fundamental ontological focus < on nationalism and patriotism. Discussing Rousseau, Waltz particularly emphasizes the notion that under the conditions of advanced civilization, a powerful state has to exist : in order to govern the people because human beings were not able to live ■> together peacefully on their own. In addition to that understanding, two additional thoughts derived from Rousseau become crucial for the develop- • ment of Waltz's (neo-) realist concept. First, he posits that it is not useful ; to examine domestic structures for the analysis of foreign policy because ' there were no causal relations between the domestic and the inter-national ;; Second, and based on that idea of foreign politics as an autonomous seg- ; ment of the state, Waltz argues that the nation-state has to be understood - as an acting unit. Both thoughts are not self-evident and thus Waltz poses ; two questions in order to develop his idea of the state as an acting unit: 'Just * how is it [the rational will of everyone] tied up with everyone else's?' (Waltz, . 1954, p. 170). And: 'Clearly states recognize no common superior, but can they be described as acting units?' (ibid., p. 173; emphasis mine). How
