Theories of magic (which assumed it worked) were described by Frazer and
other early armchair anthropologists as functioning either by Similarity or
Contagion - the doll which resembles you, or the hank of your hair.
Semiotics explains this: indeed, we do use two broad systems for filing and
communicating information, by paradigm (lists of equivalents) and syntagm
(continguous chains). Shepard and other cognitive scientists have shown
how these systems work distinctively as look-up tables versus mental maps
(roughly). I suspect Billy's two broad category match this dichotomy.
(More on this in my book THEORY AND ITS DISCONTENTS, assuming any US
library has a copy).
