Thus, the secret to becoming a better historian is really no secret at all: be aware of the various errors and fallacies noted in this book; read widely in the discipline; as you do so, ask not simply what is being said, but how the historian is going about the work of saying it; read widely in the culture of your chosen period; read eclectically across the disciplines, pillaging anything from other fields of intellectual endeavor that might help you understand the complexity of human action; read the classics of history; know the history of your discipline; and read sane accounts, by proven historians, of how they themselves pursue their craft. When you have done all this, you will find that you are a better historian than when you started.From Histories and Fallacies: Problems Faced in the Writing of History by Carl Trueman
