Curiosity is not prominent in investigations on democratic development. Nor is curiosity discussed in democratic education discourses. However, this article contributes to the present Special Issue the idea that the connection of curiosity and democracy should not be ignored. First, I show that curiosity's connection with democracy has, regrettably, been largely bypassed in fields related to democratic theory and pedagogy. Then, I elaborate on how the emerging scholarship on curiosity's intricacies makes it easier to perceive how fruitful the study of curiosity's role in democratic theory and education would be. In light of this recent rethinking of curiosity, I claim that studying a complex and ambiguous notion of curiosity (along with an equally complex and ambiguous epistemic restraint) is important for studying and advancing democracy and for enriching democratic citizenship education.
