This book started as a Ph.D. thesis at the European University Institute in Florence. It has undergone a substantial change since then and will now come to print 2 years after its defence in 2011. The road towards its publication was windy and is, regarding its contents, still not walked to an end. The biggest obstacles on this way have still not been removed: My doubts still remain as to whether my conception of markets and statecraft, regulation and law, coherence and fragmentation, collectivity and individual protection within the EU are correct. Knowing that trying to cope with such broad ideas may create more confusion than answers, I tried to conceptualize my thoughts in the best possible way and think that I cannot do any better at present. The road started at the Justus-Liebig-University in my hometown Giessen during my studies in Germany under the supervision of Patrick G?dicke , Thilo Marauhn , and Jan Schapp . Working on legal questions regarding pharmaceutical law, I was unsatisfi ed with the lack of coherency and concepts of legislation at EU level. Still being trained in the traditional continental dogmatic way, such a feeling towards EU law is comprehensible, as German legal education has trained my mind to the systematic analysis of law to an extent at which it was no question for me that law shall always aim at the establishment of a system. I am particularly grateful to my lawyer friends from the Giessen days, Markus Berliner , Franziska B?hm , Thorsten Dreimann and Til Kappen , each of whom I owe a lot to.
