Most twenty-first century ethicists conceive of character as a stable, enduring state that is internal to the agent who possesses it. This paper argues that writers in the 17th and 18th centuries did not share this conception: as they conceived it, character is fragile and has a social ontology. The paper goes on to show that Hume’s conception of character was more like his contemporaries than like ours. It concludes with a look at the significance of such a conception for (...) current debates about the place of character in ethics. (shrink)
