Fuzzed symbols are not classical symbols
OpposingArgument

#318
The dynamic patterns of neural activity Barnden correlates with symbols aren't like classical symbols, which can be composed and manipulated by well-understood logical operations: they're context dependent and only roughly correlated with events.
Christine A. Skarda & Walter J. Freeman, 1987.
Note: For discussion of the nonclassical symbolic representations, see the "Can connectionist nextworks exhibit systematicity" arguments on Map 5.

Yes: physical symbol systems can think [3]☜Thinking is a rule governed manipulation of symbolic representational structures. In humans, symbol systems are instantiated in the brain, but the same symbol systems can also be instantiated in a computer. ☜59C6EF

The Symbolic Data Assumption
The Symbolic Data Assumption☜The elements of thinking are represented in discrete, symbolic form. Beliefs, desires, goals, values, plans, etc are represented by such data and by their combination into higher order symbol structures like knowledge bases. ☜98CE71
