 Philosophers in the analytic tradition are deeply skeptical about the power of non-empirical reason to arrive at substantive conclusions about the structure of the world—including human history. Philosophical reasoning by itself cannot be a source of substantive knowledge about the natural world, or about the sequence of events, actions, states, classes, empires, plagues, and conquests that we call “history.” Rather, substantive knowledge about the world can only derive from empirical investigation and logical analysis of the consequences of these findings. So analytic philosophers of history have had little interest in the large questions about the meaning and structure of history considered above. The practitioners of speculative philosophy of history, on the other hand, are convinced of the power of philosophical thought to reason through to a foundational understanding of history, and would be impatient with a call for a purely empirical and conceptual approach to the subject.
