The opening of Preface
It is now several years since this book was begun. It has been delayed by a crowd of causes, by a temporary loss of strength, by enforced absence from England, by other occupations and interruptions of various kinds. I mention this only because of the effect which I fear it has had on the book itself. It has been impossible to make it, what a book should, if possible, be, the result of one continuous effort. The mere fact that the kindness of the publishers allowed the early part to be printed some years back has, I fear, led to some repetition and even contradiction. A certain change of plan was found unavoidable. It proved impossible to go through the whole volume according to the method of the earlier chapters. Instead of treating Europe as a whole, I found it needful to divide it into several large geographical groups. The result is that each of the later chapters has had to go over again some small amount of ground which had been already gone over in the earlier chapters. In some cases later lights have led to some changes of view or expression.
