In Knowledge and its Limits (KAIL), Timothy Williamson argues for the view that “only knowledge warrants assertion” (2000, 243). Call this the knowledge norm of assertion. Several philosophers including DeRose, Hawthorne, and Stanley, agree that if the knowledge norm is true, then knowledge itself depends on stakes, since warranted assertability seems to change with what is at stake if the proposition in question is true (1992; 2003; 2005). This brings us to the question: stakes for whom? DeRose maintains that knowledge depends on the stakes for the speaker of the knowledge attribution, arguing for Epistemic Contextualism (2002, 187). However, Hawthorne and Stanley disagree, contending that it is the stakes for the subject of the knowledge attribution which is relevant, arguing for Subject Sensitive Invariantism (2003, 157; 2005, 85). While the Contextualist and the Invariantist are armed with responses against each other’s view, I suspect that Russell’s and Doris’ indifference cases might break the impasse in favor of the Contextualist (2008, 432). This paper will thus attempt to show that the knowledge norm of assertion leads us to Contextualism rather than Subject Sensitive Invariantism, by comparing how Contextualism and Subject Sensitive Invariantism fare against Russell’s and Doris’ Indifference Cases.

My belief that Socrates was wise, and your belief that Socrates was mortal can be said to have a common focus, insofar as both these thoughts are about Socrates. In Peter Geach’s terminology, the objects of our beliefs bear the feature of intentional identity, because our beliefs share the same putative target. But what if it turned out that Socrates never existed? Can a pair of thoughts share a common focus if the object both thoughts are about, does not actually, really exist? Object-centric accounts of intentionality which explain the aboutness or directedness of thought in terms of the intentional object the thought in question is about, contend that thoughts which share a common focus do so in virtue of both thoughts simply being about the same intentional object. However, Alexander Sandgren contends that such theories face difficulties in explaining a puzzle of intentional identity put forward by Walter Edelberg, in which a pair of sentences seem to differ in truth value but are purportedly logically equivalent on the object-centric theory. If this is right, then it seems that any account which explains intentionality with reference to an intentional object is threatened by this result, whether this object be abstract, merely possible, Meinongian, or otherwise. In this paper, I argue that Edelberg’s Puzzle is analogous to Frege’s Puzzle and the same tools conventionally used to solve Frege’s Puzzle can be used to solve Edelberg’s Puzzle. I then propose a new object-centric solution to Edelberg’s Puzzle which takes into account modes of presentation and which is able to accommodate all the relevant linguistic data.
