I feel like these are separate things... neural activity being necessary but not sufficient for consciousness does not mean reductionism is wrong, it just means the fundamental building block is not a neuron.

It might not even be possible to fully understand the physical mechanisms that underlie consciousness, but that doesn't mean there has to be something more than physical mechanisms.

Yes. Even to this reductionist, “neural activity” is insufficient to describe to consciousness in the same way that “it’s physics” is insufficient to describe how a car works.

I could put a bunch of metal and rubber and gasoline in a pile and light it on fire — all the necessary ingredients for a car — but it wouldn’t create a working automobile. The arrangement of the objects and processes matters.

In the same way, if you put a bunch of brain cells together in a Petri dish, but their connections or firings were disordered, I wouldn’t expect consciousness. “Neural activity” is thus insufficient on its own, but this I doesn’t mean reductionism is incorrect. It just means you didn’t correctly reduce the problem to the correct constituent parts. You left some out.

Reductionism is a theoretical framework. It is neither right nor wrong, Sometimes a theory based on reductionism is wrong, but reductionism it self is never wrong.

Reductionism usually includes interactions of the lower parts (unless you are an atomist; in which case go back to ancient Greece), I never denied this. However even with the interactions, reductionism is still a lacking framework to describe consciousness. If it wasn’t so lacking it would be more popular among the people who actually study the mind.

I didn’t say it was wrong, I said it was lacking and unpopular among modern philosophers of science. If you want to explain consciousness as arising from interaction with the environment (like Ted Chiang did in yesterday’s article) holism is a much better approach, same if you want to use evolutionary explanations, like Daniel Dennett did at the turn of the century.

I think reductionism is simply to limited of a philosophical framework for modern science and philosophy.
