Idealism is more Rational than Materialism

[Rational AKD]

Yeah, they necessarily do..if you die, your brain will be damaged by this, and will be missing components.

obviously saying "nuh uh" doesn't gain any ground between us. what components are missing between a functioning brain, and a non-functioning in-tact brain?

yeah...fails to provide it with its material requirements...so saying that the brain of a dead person and the brain of a living person are the same, or jacking your meat about it being "intact" - as if taking chunks out is the only way to alter it's physical composition.....is idiotic.

the body can no longer replenish nutrients of the brain, but that doesn't mean these are missing from the brain upon a person's death.

Strange, because I can remove your brain and you won't show any signs of consciousness, but if I knock you the fuck out you'll return to consciousness and at no point will your brain vanish from observation from there to here.

as I said, the brain end up being the self localization of mind within space in an idealist view. obviously this self localization is dependent upon a functioning brain. so anything that can affect the brain's function also effects mind's self localization. and the material that comprises the brain is not itself contingently related to the consciousness it is localizing. so it doesn't 'disappear' just because this localization is disrupted.

That something is derived from a thing or truly fundamental to it does not imply or establish that the thing from which it is derived possesses control of it. Whiskey is derived from corn, corn is fundamental to whiskey - and yet corn doesn't control whiskey.

this is a false analogy because even though we can use corn to get whiskey, this doesn't mean corn comprises all that is whiskey. we have corn, and we have whiskey and we cannot hold they 2 in our hands and say they are the same as different corn was used to make the whiskey you have in your hand than the corn you have in your other hand. here's a better analogy that i'm sure you can be familiar with.
rocks are made of matter/energy. matter/energy has certain properties and behaves accordingly with predictable laws. therefore rocks are controlled by matter and behave accordingly with predictable laws just like matter. likewise you can say the same about consciousness... unless you want to claim rocks don't behave accordingly with the same predictable laws matter behaves by.

1 doesn't establish 2, even if given, and so can't be used to establish your conclusion by reference to 3 - even if true.

that was actually a labeling mistake on my part. 2 isn't derived from 1, rather it should be considered an independent premise. premise 2 is actually derived from the definition of control, which is the ability to directly influence something. if your consciousness is fundamental, then there is nothing outside your consciousness to influence your thoughts. therefore only you can have control over your thoughts in a metaphysical solipsist world. since in such a world everything is derived from your thoughts, it would then follow that everything is controlled by your thoughts. which brings us to premise 2.
