 Fifth, sections 15–21 state and defend what is commonly called the “Resemblance Thesis” (hereafter “RT”). It has a positive and a negative part: ideas of primary qualities resemble features of the bodies that cause them—“their Patterns do really exist in the Bodies themselves”—but “there is nothing like the ideas [of SQs] in the bodies themselves” (E 2.8.15). This is presented as an evident consequence of the claims in sections 8 through 14. The sections that follow argue directly for the positive and negative assertions.
