The hierarchical reach of Atran's cognitive universals is unclear, and
some of the key concepts used to discuss them are notorious for their
imprecision. Although ideas of class hierarchy pervade Atran's discus
sion, other ways of thinking are also allowed. The history and practic
e of systematic biology suggests that a nonclass hierarchical and cont
inuity-based way of thinking has been common there until recently.
