Getting started: objectives and justifications in the history of neurology.

Contemporary historiographical ideas have the potential to enrich the history written by practicing neurologists. Neurology is a science, and historians of neurology might profit from considering the experiences of historians of other sciences. An explicit consideration of the range of possible objectives, justifications, sources and methods of historical research may open new and exciting avenues of inquiry. Any plausible answer to the question, "What does a historian do when he or she sits down to write history" helps an historian to develop the structure of his or her project. The selection of sources for a historical study is improved, if also expanded, by understanding its aims.
