The history of ideas is the study of the development of ideas or modes of thought across time.
My next book, and one currently in the planning stage, will be explorations of themes in the global history of ideas.
Historiography is the study of the writing of history, the history of history so to speak. Several of my papers, published in History and Theory, Postcolonial Studies and other journals, explore historiographic themes.
Historiographers question the assumptions and practices of older as well as more recent historians in an attempt to avoid the biases of culture and era. Postcolonial historiographers, for instance, question the assumptions of the historians of the colonial era, although, as I have shown, this does not exempt them from biases of their own.
