Lying and misleading (roughly, making the addressee of a disingenuous claim believe something that one believes to be false, or making the addressee falsely conventionally implicate something that one believes to be false) are species of insincerity. In the course, we will deal with typological and moral philosophical questions concerning both phenomena. How can lying and misleading be adequately characterized and distinguished? What is their moral valence? Does misleading always have a moral advantage (prima facie or all things considered) over lying? Is it appropriate to use the typology to determine their rightness and wrongness? What happens when lies and misleading appear en masse and are used propagandistically?
