Historia versus politologia?

Political science came into existence from other sciences, like: history, philosophy, law, etc. Now it’s separate science which has its own quality. The interesting thing is, that people who teach history think about political science like about extra science for them and political scientists think the same way about history. Political science connects and takes from lots of scientific, for example disciplines: history, psychology, sociology, economics, law and philosophy. Making use of plenty of methods and tools for explorations is definitely an advantage. Those activities give bigger picture of scientific phenomenon. Knowledge of history lets political scientists understand causes of political phenomenon. The most important thing is to understand that both these sciences (history and political science) can help each other to find out the scientific truth.
