Even if we work in a closed enviroment, daily we give opinions on several matters, including: Philosophy, Politics, Ethics, and this to a large extent implies a responsability. When doing this we are communicating our Ideology. This is a common man activity, and is more profound for those with a Public Life, those whose work is in Government, Universities, Religión, Media, etc... Through the twentyth and twenty first century there are many reasons why the basis of Ideology has changed. Sometimes in very obvious manners like Internet, Technology,...other times and less obvious Mathematics, Language, Logic, Ontology... through changes not obvious to the Layman but certainly more profound, with a greater impact. This books tries to do a profound and fast exposure on how various fields of knowledge impact Ideology Emphasis in what we call Complex Systems, probably the Science which will impact more the future. This book does not try to convince in anything, it just presents the various theoretical basis and insists that the reader should follow them independently. Probably through courses in Internet, like those given for free in MIT, probably by conferences and certainly reading various books. After reading this book, the reader will have a better understanding of our modern society, will have more doubts, will become a Philosopher, because after all Philosophy means doubt .
