Another free will discussion

[~kitty~]

I've argued this point with my dad before and recently. How is the mind separate from the brain if changing parts of the brain can change a person, and also make predictable changes? If it were separate, this wouldn't make much sense.
He's kind of closed-minded though, so I kind of gave up once I gave him a scenario where there we created proof of the mind and brain being the same thing, and he still thought the same thing.
Just like in this case, Reincarnate, I think Cavernio might be like my dad. Some people will be stubborn due to possibly a fear that comes with being wrong about something like this.
Honestly, I feel weird thinking there's no free will, but I realize that it really shouldn't mean anything to me whether or not I do. If I do things and I can live with myself, why bother pondering it if it may ruin how I feel? What will it change?
