Many philosophers think that perceptual contents are always general and shouldn´t be specified using singular terms. They believe that distal objects and properties don't essentially constitute perceptual contents. I will argue that this strategy doesn't provide a satisfactory account of content specification and fails to make sense of the common-sense intuition that the veridicality of our perceptual experiences isn't something fully independent of whether we perceive or not. Finally, I will suggest an alternative "singularist" standpoint in which distal objects do enter into visual contents, making perceptions and hallucinations fundamentally different types of experiences.
