We may therefore now assume it to be true that nothing mental is presupposed in the fact that Edinburgh is north of London. But this fact involves the relation "north of," which is a universal; and it would be impossible for the whole fact to involve nothing mental if the relation "north of," which is a constituent part of the fact, did involve anything mental.

If we ask "Where and when does this relation exist?" the answer must be "Nowhere and nowhen." There is no place or time where we can find the relation "north of."
