How can my ideas/sensory impressions ever be incorrect? This objection is raised by Hylas, when he states “according to [Philonous], men judge the reality of things by their senses, how can a man be mistaken in thinking the moon a plain lucid surface, about a foot in diameter; or a square tower, seen at a distance, round; or an oar, with one end in the water, crooked (Dialogues, 71).
