In a forthcoming paper, I defend the view that knowledge does not require believing on the basis of evidence. In other words, I argue against what I call the "Evidence Thesis", which states:
(Evidence Thesis) S knows that p at t only if S believes that p on the basis of evidence at t.
How does the evidence thesis relate to evidentialism, formulated and defended by Earl Conee and Richard Feldman? Well, their view is about epistemic justification, and it states that the doxastic attitude one is justified in having is the one that fits the evidence. Evidentialism is a popular view, and we can see that it is distinct from the evidence thesis. However, VERY MANY evidentialists endorse the evidence thesis. So do VERY MANY internalists. On the other hand, almost no externalist will endorse the evidence thesis. So long as one's true belief was produced in the right way (e.g., by a reliable process, with safety, with sensitivity, by properly functioning faculties, by an exercise of the right sort of ability, etc.), the belief counts as knowledge. Despite the fact that some people seem to presume the truth of the evidence thesis, we can see that a great many theories of knowledge (the externalist ones) entail that it is false. And I argue that it is false in my paper. So, my argument both provides support for the many externalist theories of knowledge and also gives many evidentialists and internalists a reason to revise their views.
In this post, I want to try out a counterexample against the evidence thesis.
