摘要：Perspectives on Federalism is closing its seventh year and its issue 2/2015 confirms the interdisciplinary nature of this intellectual enterprise. This issue is a very rich one, as it includes legal, historical and philosophical contributions. In spite of the evident diversities of these articles, we can identify three main connecting themes: latest developments in EU law, history of thought and European integration, and constitutional developments in national and supranational contexts.
