  Another version of Nominalism is Resemblance Nominalism. According to this theory, it is not that scarlet things resemble one another because they are scarlet, but what makes them scarlet is that they resemble one another. Thus what makes something scarlet is that it resembles the scarlet things. Similarly, what makes square things square is that they resemble one another, and so what makes something square is that it resembles the square things. Resemblance is fundamental and primitive and so either there are no properties or the properties of a thing depend on what things it resembles.
