The Illusion of Qualia

David's version of the thought experiment: You are a biochemist with a genetic defect that disables the blue receptors in your retinas. After being cured you will experience a similar quali to that of seeing the blue card but there is one thing that neither you nor anyone else could predict about the outcome of this experiment and that is what blue will look like "I consider this exciting evidence that there is a fundamental discovery to be made which will integrate things like qualia into our other knowledge," he says.
