 On these accounts truth plays a unique and necessary role in assertoric discourse (Price 1998, 2003, 2011; Misak 2000, 2007a, 2015): without the concept of truth there would be no difference between making assertions and, to use Frank Ramsey’s nice phrase, “comparing notes” (1925 [1990:  247]). Instead,  truth provides the “convenient friction” that “makes our individual opinions engage with one another” (Price 2003: 169) and “is internally related to inquiry, reasons, and evidence” (Misak 2000: 73).
