Abstract
I discuss an argument for non-conceptualism based on animal and infant per-
ception. Crudely put, some animals and infants who possess no concepts nonetheless have perceptual states with non-conceptual content. Perceptual experiences of adult humans have the same kind of content as the experiences of animals and infants, so the content of the perceptual experiences of adult humans is also non-conceptual. I defend this argument against potential attacks from the conceptualist. I argue that there are indeed creatures which possess no concepts, but have perceptual experiences, and I attack McDowell’s view that we share perceptual sensitivity with animals and infants, but not genuine perceptual contents.
