Despite the aforementioned agreements between Carr and Morgenthau, these complicated thinkers hold different perspective about the politics which rooted in human nature and that leaded to a discordant tone in the attitudes of the international politics: Carr wished to build a “new utopia”, a realistic world order (Carr 2001, 87); whilst Moegenthau regards the international politics as a tragedy. The reason could have lied on the different writing times, and the different interpretions of human nature. Carr argues that Man is an Aristotelian political animal (Carr 2001, 95) whom live in the social context. The affiliation with groups, or political communities ensures that Man’s more anti-social instincts are being tamed and group norms regulate the relations among members. These kinds of relations are mostly peaceful and normally follow a commonly shared morality (Schuett 2010, 39); but Morgenthau regars that Man is an Sisphusian political animal. Man is characterized by both an insatiable lust for power (ibid) and a need to act in conformity to what Man regards as being ethically right (Cozette 2008, 669).
