The best hypothetical I could come up with is Humans > Science >
Anthropology > Humans. Anthropology is a subset of Science, but
Science is something done exclusively (that we know of) by humans, and
Humans are Anthropology's subject of study. If we separated "strict
sub/superset" (as current category system) and "related to" (not as
current category system: symmetric and non-transitive), as many have
suggested, there should never be any need for circularity.
