I can remember picking up weighty tomes on the history of science and the history of philosophy and reading those when I was small.
Peter AckroydWhy should a novelist not also be a historian? To force unnatural divisions within the English language is to work against its capacious and accommodating nature. To expect a writer to produce only novels, or only histories, is equivalent to demanding from a composer that he or she write only string quartets or piano sonatas.
