Conclusion - The Summary of This Book: "I have taken the liberty once or twice of borrowing the excellent phrase about an Outline of History; though this study of a special truth and a special error can of course claim no sort of comparison with the rich and many-sided encyclopedia of history. for which that name was chosen." Appendix I - On Prehistoric Man: "On re-reading these pages I feel that I have tried in many places and with many words, to say something that might be said in one word. In a sense this study is meant to be superficial. That is. it is not meant as a study of the things that need to be studied. " Appendix II - On Authority and Accuracy: "In this book which is merely meant as a popular criticism of popular fallacies, often indeed of very vulgar errors, I feel that I have sometimes given an impression of scoffing at serious scientific work."
