Size/Direction/Bigelow/Pargetter: e.g. two-digit relation between velocities
E.g. Two points on the homogeneous rotating disc on the same radius:

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.
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).
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.
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. ((s) because of the causal forces?).

Difference/Bigelow/Pargetter: this allows us to specify the size of differences.
Grades/size/differences in size/difference/Frege/Whitehead/Wiener/Quine/Bigelow/Pargetter: (see above, similar to the quantities) (Lit. Frege 1893, Whitehead/Russell 1910 vol 3 p. 6 "Quantity", Quine 1941, Bigelow (1988a) Solution: Relations between relations.
