Classical realism and neorealism are often confused. While classical realism is based on ethical assumptions, neorealism is based on positivist assumptions. Classical realism is often considered amoral. It is the opposite – morality and ethics are paramount for classical realism, along with the notion of power (Kurki, Wight, 2013: 15). Neorealist scholars also critisise classical realism for resembling ideology, rather than scientific theory (Lebow, 2013: 60). The key difference between the two theories is though their answer to the main question of the realist tradition: Why states want more power? For classical realism it is ‘because of the hubris-based human nature.’ The answer of neorealism is ‘because of the structure and architecture of the international system’ (Mearsheimer, 2013: 78). For classical realism power is an end in itself, whereas for structural neorealism it is a means to an end (Mearsheimer, 2013: 78).
