 Along with Fodor, Dretske, Evans, Recanati, and Lewis, Frank Jackson (2010) also articulates a semantic theory based upon information channels that supervene on causal relations, along with MOPs. Jackson’s MOPs are identified with descriptions. Jackson’s description theory of reference for proper names turns on information channels, which are articulated in terms of causal links that underpin information flow. Jackson’s motivating idea is that names are by and large sources of information about the entities that they name. The descriptive dimension is a function of their (the descriptions) being specified in terms of information-carrying causal connections—information channels.
