I articulate and argue for a modest use to which philosophers who are not historians of philosophy might put the history of philosophy. That use is in conceptual cartography. I understand conceptual cartography to be the practice of mapping how concepts, including those as complex as philosophical views, relate. Using the history of philosophy in conceptual cartography uses that history to situate landmarks on a conceptual map, and then situates other views (historical or contemporary) relative to those landmarks. After articulating (...) and arguing for this use, I consider objections. (shrink)
