6. Relation only betwixt two things.
Whatsoever doth or can exist, or be considered as one thing is positive: and
so not only simple ideas and substances, but modes also, are positive beings: though the parts of which they
consist are very often relative one to another: but the whole together considered as one thing, and producing in us
the complex idea of one thing, which idea is in our minds, as one picture, though an aggregate of divers parts, and
under one name, it is a positive or absolute thing, or idea. Thus a triangle, though the parts thereof compared one
to another be relative, yet the idea of the whole is a positive absolute idea. The same may be said of a family, a
tune, etc.; for there can be no relation but betwixt two things considered as two things. There must always be in
relation two ideas or things, either in themselves really separate, or considered as distinct, and then a ground or
occasion for their comparison.
