There are 7 papers here, representing (hopefully) a range of ideas. We will start with one of my favorite theorists on the neural organization of semantic memory: Carl Wernicke. Yes, that's right, he didn't just do language. Although Wernicke hinted at his views on the topic in his classic language writings, his most thorough description of his theory was published in 1900 in a volume titled, Grundriss der Psychiatrie. This volume has not been translated into English except for a few portions which appear in Gage & Hickok (2005). Skip the commentary and just read the excerpts -- I think you will find Wernicke's ideas to be extremely modern-sounding.
