Hi! I've read some philosophy stuff and I came to notice some kind of a "family resemblance" among some pairs of philosophical terms. You work with dichotomies such as type/token, concept/referents, set/members, whole/parts, object/appearances, property/instantiation, description/satisfaction... Well, you'll know many more of those than I do. My question is: do you have a general name for all those dichotomies? Thank you!
