You're on to something.

I once met a person who was anti-anything which isnt coming from her own mind.

Science? Nah, she got "power of her mind" to bend and twist metals(move objects around - only if she could just focus and use more than 10% of her brain.

We got into a heated discussion about knowledge, science and philosophy, it all boiled down to "I believe whatever I want and thats the only thing that matters, no matter what you say or how things appear or whatever else".

At one point I asked her how she knows that she is right about that about anything, she said she doesnt really but she chooses to believe it. And hence anything, science, philosophy, knowledge, if the rock over there really is hard and if it really is going to fall to the ground if I keep it in the air and drop it, its all a matter of belief, and if people believe it hard enough it wont necessarily always fall to the ground.

How would you approach further discussion with her?

I think there was more to it than "I believe whatever I want". That's just her pride talking.

Heated arguments aren't very helpful IMO. I have a good friend who still believes the Earth is 5000 years old, but the last thing I want to do is bash his head into science.

That takes a long conversation over coffee (hopefully several cups) and ensuring that I don't make him feel like I'm looking down on him for what he believes. That's the worst way to convince anyone of anything, reality or not.

People have a tough time separating belief from idea. Beliefs need no evidence, but ideas are testable. Find out what her ideas are and we can move on to her beliefs later (or maybe you won't even need to go that far when she realizes the fallibility of unyielding belief).
