 Connectionists raise many objections to the classical computational paradigm (Rumelhart, McClelland, &amp; the PDP Research Group 1986; Horgan &amp; Tienson 1996; McLaughlin &amp; Warfield 1994; Bechtel &amp; Abrahamsen 2002), such as that classical systems are not biologically realistic or that they are unable to model certain psychological tasks. Classicists in turn launch various arguments against connectionism. The most famous arguments showcase productivity, systematicity of thought, and systematicity of thinking. Fodor and Pylyshyn (1988) argue that these phenomena support classical CTM over connectionist CTM.
