In this paper, I argue that facts about the history or genealogy of concepts (facts about what I call “conceptual history”) can matter for normative inquiry. I argue that normative and evaluative issues about concepts (such as issues about which concepts an agent should use, in a given context) matter for all forms of inquiry (including normative inquiry) and that conceptual history can help us when we engage in thinking about these normative and evaluative issues (which I call issues in “conceptual ethics”). My aim in making this argument is to develop a schematic framework for thinking about the relationship between conceptual history and normative inquiry. The framework puts pressure on those who, often unreflectively or implicitly, dismiss the potential relevance of conceptual history to normative inquiry. At the same time, the framework can be seen as presenting a challenge to those drawn to more radical views about the relationship between conceptual history and normative inquiry. The challenge is this: if one wants a more ambitious model of the relevance of conceptual history to normative inquiry than what I provide in this paper, one needs to explain what justifies such a model.
