Only a Europe that is conscious of its own values can be both an economically strong and a morally and intellectually respected partner, and thereby extend its hospitality to others. It's a cultural disgrace that we are forced to identify no-go areas for foreigners.

A Europe that qualifies its own values is not attractive in the eyes of Muslims. Europe must conduct itself as a strong partner, both intellectually and spiritually, and it must be convinced of its own advantages. This is the only way we will gain respect.

The end of World War I also marked the end of bourgeois culture. An inner emptiness developed that, in the 19th and 20th centuries, paved the way for two ideologies that dragged Europe and the world into an abyss and plunged it into a catastrophe.

The fundamental issue, when it comes to Europe's future, will be whether and how we manage to transfer the ideals that once made Europe great - especially its Christian roots - into today's changed world. No one wants to return to the Middle Ages.

Where it is the majority religion, Islam does not recognize religious freedom, at least not as we understand it. Islam is a different culture. This doesn't mean that it's an inferior culture, but it is a culture that has yet to connect with the positive sides of our modern Western culture: religious freedom, human rights and equal rights for women.

The distinction between radical Islam and moderate Muslims is important, as are the differences between Sunnis and Shiites, and between militant and mystical Islam.

The religious wars showed that the Christian faith was no longer Europe's unifying force. A new common ground was needed, and it was found in reason, which is something that is shared by all of mankind. This was one of the roots of the Enlightenment and its concept of universal human rights.
