Political and historical studies are still severely handicapped by the absence of an historical dictionary of political terms and slogans. Without such a dictionary the investigation of significant political expressions is still very difficult and time-consuming, while the process of critical political self-understanding and education lacks a vital tool. The great philological dictionaries of the European languages are of little help in this field of political semantics, because they have been the work of scholars whose main interest was philology and literature. International links, historical perspective, and political sensitivity can be found in no dictionary of the English, French, or German language. Littré's French dictionary notes that Europe is the name of a number of heavenly bodies and plays a part in Greek mythology. The Oxford English Dictionary, on the other hand, treats Europe as a proper name and omits it altogether. Without the benefit of competent lexicographical guidance the intensive historical study of the idea of Europe, which has been carried out for the last twenty years, has failed to discover the time and circumstances which led to the adoption of Europe as a symbol of political interest. The main fault of past historical investigations lies in a concentration on literary works and famous men of letters and a neglect of political literature, pamphlets, and diplomatic documents. Political expressions are the offspring of national and international conflicts. They become stereotyped symbols of loyalty or enmity and one criterion of their establishment in political life is the frequency of their use—and abuse—by one recognizable political group. When and how did this first happen to Europe?
