Abstract
When a subject has perceptually grounded knowledge, she typically knows how she knows what she knows, and is able to appeal to perceived items and her own experiences in reason-giving practices. What explains this ability? In this paper I focus on vision, and I submit that paradigmatic cases of visual perceptual knowledge are such that, when a subject acquires knowledge that p by seeing that p, she also acquires tacit knowledge that she sees that p; I also argue that the truth of this thesis is grounded in phenomenological facts concerning awareness and self-awareness.
