界，境也——《说文》

Boundary, Limits and no limits.

“界”字，表示划定界线区分之意，然而从另一方面来讲，阻隔一旦打开，即能成为自然融通的统一层面，因此相分又不分，正是“界”的辩证内涵。我们开设《欧洲界》这样一个栏目，即具有这样的意味。

＂界（Jie）＂ generally means boundary, which separate areas and determining their limit. However, boundary naturally connects areas when estrangement is diminished. ＂界＂ defines this indefiniteness and multi-nature of boundary, which is naturally communicating, harmonizing while it is separating. This right is the philosophical connotation of ＂界＂ .
