The Multiple Realisability Defence
It's not possible to formulate rules for connectionist representations (or representation instantiation rules), because such representations can be realised by multiple node level descriptions.

A representation of dog, for example, can be realised in a variety of different (though similar) node-level activation patterns.

Thus, no single node-level description can fully describe the dog representation.

Moreover, node-level discrepancies make it possible for the dog representation to produce a variety of different behaviours.
