The biological theory can be considered as the corner stone of political power. Aristotle, the father of this theory clearly states that humans have an innate need to form groups based on dominance hierarchies. In itself it fails to sufficiently explain how and why political systems are established, and this weakness paves the way to consider others, such as the psychological and the cultural theories.
The psychological theory states that humans have a deep-seated need to fit into groups and stay within the group norms where, as the cultural theory states, human behavior related to "politics" is learned and not inherited. The psychological and cultural factors both interact with the environment and events occurring during a period of time in a certain society, and lead to the establishment of a certain overwhelming state of mind. For example, after its defeat in World War I, the german society was flooded with shame, hate, and most of all a very low morale, where as the French society, after the French Revolution, was overjoyed, ambitious, and dreamed of a better lifestyle. The state of mind established by these two main factors plays a key role in the application of both the rational and irrational theories.
The rational theory by definition states that political power is based on the ability to reason as opposed to the irrational theory that is based on fear and propaganda. The application of one or the other is mainly dependent on the nature of the state of mind dominating the society in
