Of course, alliteration is simply a special case of chiasmus or, perhaps, antimetabole. Both can be used in the structure of entire passages to parallel concepts or ideas. This process, termed "conceptual chiasmus", uses a criss-crossing rhetorical structure to cause an overlapping of "intellectual space". Conceptual chiasmus utilizes specific linguistic choices, often metaphors, to create a connection between two differing disciplines. By employing a chiastic structure to a single presented concept, rhetors encourage one area of thought to consider an opposing area's perspective. Do not confuse them with antanaclasis.
