The jury is still out. Despite our advancements and accomplishments we know astonishingly little about human consciousness, and how exactly is it that organic chemistry can produce a being that perceives, thinks, dreams and produces unbelievable achievements in every way imaginable.

But first things first, let's check the language we're using. Whereas the brain is a physical organ situated inside the skull, the mind is an abstraction. What we call "the mind" is actually a set of functions - our capacity to perceive, analyze, dream up and influence reality (there is probably a more comprehensive way to describe it, but I'm shooting from the hip here). My point being that "the mind" is a roof term not an observable object.

It's still a very useful term and I don't want to downplay it in the least, but, almost paradoxically, it only exists inside the mind via language.

Now whether our thoughts and dreams are produced inside our brains and we all make up our own minds (pun intended), or whether the brain is more akin to a receiver-broadcaster that channels the mind, is a matter of opinion, not fact. There's no evidence to support either, and science usually picks the more conservative estimate, whereas spiritualism is more liberal. But they both know exactly the same amount, which is almost nothing.
