A Role for Qualia

If qualia are mental, and if the mental is functional, then so are qualia. But, arguably, qualia are not functional. A resolution of this is offered based on a formal similarity between qualia and numbers. Just as certain sets “play the role of” the number 3 in Peano’s axioms, so a certain physical implementation of a color plays the role of, say, red in a (computational) cognitive agent’s “cognitive economy”.
