Classical realists state that man is naturally egotistical and has an endless will to gain power. As animus dominandi, he constantly seeks to make others the subject of his domination. Since this state is considered human nature, it is also a result of the state of nature, the pre-civil condition that is an extremely adverse human circumstance in which life is ruled and shaped by a permanent state of war of every man against every man. This constant fear of death has resulted in humans engaging in rational collaborations due to security concerns. As such, human nature lies at the root of politics.
