 Walsh suggests that the philosophical content of the philosophy of history falls naturally into two different sorts of inquiry, parallel to the distinction between philosophy of nature and philosophy of science. The first has to do with metaphysical questions about the reality of history as a whole; the latter has to do with the epistemic issues that arise in the pursuit and formulation of knowledge of history. He refers to these approaches as “speculative” and “critical” aspects of the philosophy of history. And he attempts to formulate a view of what the key questions are for each approach. Speculative philosophy of history asks about the meaning and purpose of the historical process. Critical philosophy of history is what we now refer to as “analytic” philosophy; it is the equivalent for history of what the philosophy of science is for nature.
