Mind is the brain?

[robvalue]

Minds have never been shown to exist without brains. This is evidence (not proof, science doesn't deal with proof) that minds require a brain. As soon as someone finds a mind without a brain, we will have a reason to reconsider.

All evidence is observational, and conclusions can change based on new evidence. Every time I drop a ball, it falls down. It is reasonable to conclude, based on this evidence, that (at least in my local area) this will continue to be the case. I can never know for sure that it will actually continue to be the case.

All we can do is model as best we can. Maybe somewhere out there, in our reality or otherwise, gravity doesn't apply. Maybe out there somewhere, there are minds without brains. But until we have any evidence to suggest that this is actually the case, it is not logical or useful to jump to that conclusion.

Science keeps all possibilities open, it does not make statements of certainty. So demanding science (or scientists) to admit to not being certain is asking for what you already have.
