According to the quasi-perceptualist account of philosophical intuitions, they are intellectual appearances that are psychologically and epistemically analogous to perceptual appearances. Moral intuitions share the key characteristics of other intuitions, but can also have a distinctive phenomenology and motivational role. This paper develops the Humean claim that the shared and distinctive features of substantive moral intuitions are best explained by their being constituted by moral emotions. This is supported by an independently plausible non-Humean, quasi-perceptualist theory of emotion, according to which the phenomenal feel of emotions is crucial for their intentional content.
