When we say Europe, what do we mean? Perhaps it has never been more necessary than it is today to apply not emotion but scientific method in answering this question. If we ask the politicians they will tell us of the continuity of Europe and its function in world politics. The geographer will speak of the special qualities of the soil and the flora. Might we not usefully regard the map of Europe from the point of view of the other, so much more extensive continents? From that point of view, would the continent of Europe seem to be an annex of Asia or Africa? No, certainly not. There are grounds of paramount importance which make such a view impossible: reasons, determined by the common history of the European nations and the common civilisation which was the product of their historical development.
