 Before moving on, it is important to note that these are certainly not the only important questions about testimony. For instance, there is a growing literature about how failing to give a testifier the credit they deserve gives rise to a form of epistemic injustice (e.g., M. Fricker  2007).[1]  Moreover, there are many interesting questions about eyewitness testimony and the law (e.g., Wells &amp; Olson 2003 and Burroughs &amp; Tollefsen 2016), as well as important questions about the relationship between testimony and assertion (e.g., Pagin 2007 [2016]). And there are also growing literatures about moral  testimony[2]  and aesthetic  testimony,[3]  e.g., while it is uncontroversial that you can acquire justification for believing that the taco truck is open by relying on your friend’s say-so, it is far less clear that you can acquire justification for believing that eating carne asada is morally wrong or that the mural on the taco truck is beautiful, solely on the basis of what your friend tells you. For reasons only having to do with space, though, this article will focus exclusively on the seven questions above.
