There's an influential taxonomy by the anthropologist Alan Fiske, in which relationships can be categorized, more or less, into communality, which works on the principle "what's mine is thine, what's thine is mine," the kind of mindset that operates within a family, for example; dominance, whose principle is "don't mess with me;" reciprocity, "you scratch my back, I'll scratch yours;" and sexuality, in the immortal words of Cole Porter, "Let's do it."
Antropologul Alan Fiske a formulat o influenta taxonomie, in care relatiile pot fi categorisite, mai mult sau mai putin, in comunalitate, care functioneaza pe principiul "Ce e al meu e si al tau, ce e al tau e si al meu" -- genul de mentalitate care opereaza in cadrul unei familii, de exemplu -- dominanta, a carui principiu este "Nu te pune cu mine," reciprocitate: "o mana spala pe alta", si sexualitate: in cuvintele nemuritoare ale lui Cole Porter, "Hai la treaba."
