Political science-fiction/double feature

I started studying law, then I thought it was really not worth it spending precious hours of my short life-span reading tons of useless books and learning by heart meaningless rules that were in them anyway (not to mention the conceitedly loftiness of the legal scholars) -- although I was saying goodbye to an awful lot of cash. Then I turned to political science, which I thought was way cooler. But in there I realised that nobody was actually doing "political science". Some were continuing law by other means. Some were worshipping economics and its methods of assuming everyone is rational and calculating the maximisation of their equally rational interest, while giving a (third) hand to the greater good. Others decided that history would better inform present situations, since we address present issues based on past solutions, which determine our path for the future. Others argued that institutions were about the people, so one must study the people in society and their behaviour. Others decided that really, all this literature was not worth it and started reading the real one, then imported post-modern views that identity and texts shaped people's interests so one should deconstruct, hermeneuticise or genealogise discourses.
This is why I am now turning to philosophy  and the history of ideas -- farewell for ever sweet cash flow!
Actually, doing so, I came across a few ideas about the origins of political science. During the Enlightenment, in France, people started worshipping reason as the universal and objective tool to understand nature. Since there was a natural science based on the observation of nature, there should equally be a human science based on the observation of man. People like Holbach or Mably started the foundations of a "moral science". In 1795, the French "Académie des sciences morales et politiques" was founded to inform and improve our human all too human condition. Ever since, there have been "scientists" to believe in it and search for it with a Kantian lantern. I suspect that what keeps them going on searching in the obscurity is that they cannot light the whole room to realise they might have been turning in circles.
