Boyd Millar works in the philosophy of perception and social epistemology.
His recent work concerning perception defends the view that perceptual experiences put us in contact with ordinary physical objects and their properties via unique manners of presentation: sensory qualities and sensations that function as representational vehicles.
His recent work concerning social epistemology defends the view that individuals are often not blameworthy for their problematic beliefs when considered in isolation, but that groups of individuals are often jointly blameworthy for their members’ problematic beliefs (in virtue of having violated some shared epistemic obligation).
