Abstract
In response to Ari Armstrong's essay, "A Direct Realist's Challenge to Skepticism," Huemer defends his views on two issues concerning the nature of perception, against the Objectivist position: First, he argues that perceptual experiences have propositional but nonconceptual content; second, he argues that in perceptual illusions, the senses misrepresent their objects. He finds that the Objectivist view that perception cannot misrepresent because it lacks propositional content not only is absurd but opens the door to philosophical skepticism
