PRAGUE -- Europe is in search of its identity. I believe it is easy to find: The European Union embodies the principle of open society, which could serve as a force for a global open society. Let me explain what I mean.

The concept of an open society was first used by the French philosopher Henri Bergson in his book "The Two Sources of Morality and Religion."

One source, according to Bergson, is tribal and leads to a closed society whose members feel affinity for each other but fear or hostility toward others. The other source is universal, leading to an open society guided by universal human rights that protects and promotes the freedom of the individual.
