The title under which I here collect my three Essays is chosen for the purpose of indicating that I have followed that retrogressive method 'from the known to the unknown,' of which Mr Seebohm is the apostle. Domesday Book appears to me, not indeed as the known, but as the knowable. The Beyond is still very dark: but the way to it lies through the Norman record. A result is given to us: the problem is to find cause and process. That in some sort I have been endeavouring to answer Mr Seebohm, I can not conceal from myself or from others. A hearty admiration of his English Village Community is one main source of this book. That the task of disputing his conclusions might have fallen to stronger hands than mine I well know. I had hoped that by this time Prof. Vinogradoff's Villainage in England would have had a sequel. When that sequel comes (and may it come soon) my provisional answer can be forgotten. One who by a few strokes of his pen has deprived the English nation of its land, its folk-land, owes us some reparation. I have been trying to show how we can best bear the loss, and abandon as little as may be of what we learnt from Dr Konrad von Maurer and Dr Stubbs. For my hastily compiled Domesday Statistics I have apologized in the proper place. Here I will only add that I had but one long vacation to give to a piece of work that would have been better performed had it been spread over many years.
