 This theory takes different forms. One form it takes is that associated with people in the scientific tradition, e.g., Descartes, Boyle, Newton and Locke. This is the view that colors are secondary qualities. However, as we saw earlier, in  section 1.2,  this form of the dispositionalist view was part of a complex package, related to the emerging scientific world-view. For our current purposes, there are two crucial components to this package. The first is the idea that we should distinguish between two notions of color: color as a property of physical bodies, and color as it is in sensation (or, as it is sometimes described, “color-as-we-experience-it”). The second is that the secondary quality view is not thought of as capturing the common-sense, or “vulgar”, way of thinking of color. Rather, it is thought of as a revision or reconstruction of the ordinary concept.
