Family therapists use concepts germane to other academic disciplines. We re
count four notions-context, explanatory metaphors, language conventions, an
d persistently refining knowledge-that family therapists and paleontologist
s each utilize. Revisiting family therapy's foundational concepts through t
he lens of another discipline reminds us of our theoretical beginnings, hig
hlights those professional adaptations that we have made over the years, an
d offers us an opportunity to reinvigorate and expand our central organizin
g principles.
