On Truth is a 2006 book by Harry Frankfurt, a follow-up to his 2005 book On Bullshit.{{cite news|url=https://www.nytimes.com/2006/11/12/books/review/McCulloch.t.html|title=Sunday Book Review - Bull Session|last=McCulloch|first=Alison|date=November 12, 2006|work=The New York Times|accessdate=12 October 2016}} It develops the argument that people should care about truth, regardless of intent to be truthful. It explicitly avoids defining "truth" beyond the concept commonly held, which corresponds to reality.{{cite news|last1=McCulloch|first1=Alison|title=On Truth By Harry G.
