This is ""not a book about the Common Market only, and still less a tract urging that Britain join, or not join, the European Community. It is simply a brief history of a great movement."" In clear, terse language, and for the most part avoiding material already amply covered by other studies of the subject. It outlines the political and economic backgrounds of all the important stages through which the concept of a united Europe has gone, ever since the notion of such an entity emerged. It then proceeds to describe the workings, and to analyze the various virtues and shortcomings, of E.C.S.C., Euratom, the Common Market, and possible further developments towards a real and effective federation. There is also an excellent chapter detailing the pros and cons of Britain's entry. Mr. Mayne ""has worked on the European Community staff for the past six years"" and admits that he finds it ""almost impossible to feel detached"" about his subject, but he has ""tried to be objective"". The reader's decision on whether or not he succeeded in being ""objective"" will depend in large part upon the reader's own feelings regarding the meaning and purpose of the Community; certainly, no one can deny that Mayne has been both instructive and persuasive.
