"In this slim, dense, and heavily text-based book, Mora-Márquez traces the development of the semantic notion of “signification” (significatio) from its origins in two distinct Greek philosophical conceptions, semeion and symbolon, into a uniquely medieval concept. Because medieval philosophers drew from both logical and grammatical traditions when discussing signification, there is no unified conception of the notion that holds across the entire thirteenth century or in all relevant disciplines. Mora-Márquez teases out the differences, explains how they relate to each other, and identifies the roots of the differences... For the specialist, [this book] is a phenomenal resource, meticulously researched, interesting in content, and filling a very important gap in our understanding of semantic theory in the thirteenth century."
