To deny qualia today is like the behaviorists who denied cognitive processes yesterday. You are smarter than that!

Without being able to offer functional criteria for judging whether 'cognitive processes' exist, it would certainly be inappropriate to talk about them.

Cognitive psychologists not only managed to produce an experiment that would distinguish between "having cognitive processes" and "not having cognitive processes", they performed it and resolved the dispute.

What experimental results would be enough to convince you that 'qualia' did not exist?
