THE FIVE DEATHS OF THE FAITH 288 CONCLUSION: THE SUMMARY OF THIS BOOK 302 APPENDIX I.: ON PREHISTORIC MAN 313 APPENDIX II.: ON AUTHORITY AND ACCURACY 315 INTRODUCTION THE PLAN OF THIS BOOK There are two ways of getting home; and one of them is to stay there. The other is to walk round the whole world till we come back to the same place; and I tried to trace such a journey in a story I once wrote. It is, however, a relief to turn from that topic to another story that I never wrote. Like every book I never wrote, it is by far the best book I have ever written. It is only too probable that I shall never write it, so I will use it symbolically here; for it was a symbol of the same truth. I conceived it as a romance of those vast valleys with sloping sides, like those along which the ancient White Horses of Wessex are scrawled along the flanks of the hills. It concerned some boy whose farm or cottage stood on such a slope, and who went on his travels to find something, such as the effigy and grave of some giant; and when he was far enough from home he looked back and saw that his own farm and kitchen-garden, shining flat on the hill-side like the colours and quarterings of a shield, were but parts of some such gigantic figure, on which he had always lived, but which was too large and too close to be seen. That, I think, is a true picture of the progress of any real independent intelligence to-day; and that is the point of this book.
