Looking out the window, I see that it’s raining outside. Do I know that it’s raining outside? According to proponents of the Entailment Thesis, I do. If I see that p, I know that p. In general, the Entailment Thesis is the thesis that if S perceives that p, S knows that p. But recently, some philosophers (McDowell, in Smith (ed.) Reading McDowell on mind and world, 2002; Turri, Theoria 76(3):197–206, 2010; Pritchard, Philos Issues (Supplement to Nous) 21:434–455, 2011; Pritchard, Epistemological disjunctivism, 2012) have argued that the Entailment Thesis is false. On their view, we can see p and not know that p. In this paper, I argue that their arguments are unsuccessful.
