Absolutely true, however it's a bit overzealous to jump from starting to understand how the brain works to materialistic assumptions about the nature of consciousness of free will.

[a-priori]

See, from my perspective it's overzealous to assume that the conscious mind is not materialistic in nature.

With a question as ill-posed as the nature of consciousness, what's reasonable and what's overzealous depends entirely on your perspective.

Yes it's overzealous to assume either way. That's why it's philosophy not science.
