Does our application of concepts in perception have a role in our understanding of the objectivity of what we perceive? I clarify a specific version of this question and present an argument for an affirmative answer: Conceptualism. I develop an objection to the resulting position drawing on Mackie's discussion in “Perception, Mind-Independence, and Berkeley”, offer an alternative Anti-Conceptualist account of perceptual objectivity, and explain where I think the argument for Conceptualism, and also Mackie's reaction to it, go wrong.
