No current theory of consciousness is scientific

Challenging the "pseudoscience" objection

A letter by distinguished scientists sought to discredit a leading theory of consciousness as pseudoscience. That was mistake. No theory of consciousness is currently empirically testable, so strictly speaking, no such theory is scientific, argues Erik Hoel.

 

Last week, over one hundred scientists, many prominent or even world-famous, debuted a signed letter declaring that one of the most popular scientific theories of consciousness is “pseudoscience.” The letter is directed at Integrated Information Theory (IIT), and its signers go so far as to say that:

“As researchers, we have a duty to protect the public from scientific misinformation.”

Sparked by the recent press around an international “adversarial collaboration” that pitted the predictions of theories of consciousness against one another, the letter is quite short, just a few paragraphs, and the number of signees outweighs the number of citations by an order of magnitude. Yet the names include many well-known researchers in the field, such as Hakwan Lau, Joseph LeDoux, Bernard Baars, Patricia Churchland, Daniel Dennett, and Keith Frankish, along with plenty more (although there are noticeable absences).

The problem at the heart of this discussion is that science should be empirically testable. Yet mathematics does not require this. In mathematics hypotheses or theorems must be proven to be true or false. Only conjectures are open ended. But Godel et alii proved that no mathematical framework is complete and no mathematical framework can prove its own consistency.
With the advent of quantum physics the entire issue of science, empirical science to be precise, and it's testability has come under scrutiny. Big Bang theory, cosmology and the standard model of particle physics are now all buckling under the pressure of new empirical findings.
The problem, too often completely ignored, but described eloquently by both Western and Buddhist philosophers is that empirical science depends on observation, i.e. sensory input. And according to the Buddhist philosophy of the Madhyamaka Middle Way sense perception is flawed. According to Western philosophers observation, perception, knowledge representation, cognition and consciousness are all subject to discussion.
What we need is a new framework for science which captures mathematically the limitations of sense perception and observation. And which does away with the notion that everything should be empirically testable.
