Perceptual optimism entails perceptual realism, the view that there is a reality out there which is accessible to our senses in some way or other, and the belief that our senses are veridical at least to some extent, but it is more comprehensive than that. For instance, a perceptual optimist does not admit such things as qualities which are perceptible in principle but not by us or bodies too small to be perceptible. In this paper I argue that Aristotle is a perceptual optimist, since he believes that reality, at least in the sublunary sphere, is indeed fully accessible to our senses. In the first and largest part of this paper, I will show, in seven distinct theses, what Aristotle’s perceptual optimism entails. In the second and shorter part, I will put Aristotle’s position in a wider context of his epistemology and show why it was important for him to be a perceptual optimis
