Two points on the homogeneous rotating disc on the same radius: I 75 Then their instantaneous velocities have the same direction. At the same time, they differ in size due to the different distances from the centre. Common/Solution/Bigelow/Pargetter: the common is a property of the 2nd level (sic): the property to have a velocity with that and that direction. Correspondingly the opposite for points of a circle around the center: Commonality: the property of the 2nd level to have a velocity with that and that size. Vectors/Bigelow/Pargetter: have properties of the 2nd level (sic) i. e. properties of properties. >Vectors/Bigelow. Equality/Vector/Bigelow/Pargetter: if two vectors share one of the properties of the 2nd level, say, for example, they have the same direction or the same size. (Same direction, same size). >Universals, >Universals/Armstrong. Identity/Vector/Bigelow/Pargetter: two vectors are identical if they share all properties of the 2nd level (here: size and direction). Flux/Vector: through this concept of identity, the Flux theory can understand vectors. >Flux/Bigelow. Universals/Bigelow/Pargetter: in the case of vectors, we assume that both properties of the 2nd level and properties of the 2nd degree are real universals. Namely, a posteriori universals in the sense of Armstrong. Because the common denominator of the points mentioned above on the disc is not merely a linguistic phenomenon. I 76 Difference/Bigelow/Pargetter: this allows us to specify the size of differences. >Distinctions.
