I'm not even going to discuss this any further. You know the point I'm making is: headaches can be studied as something that is an actual medical sympton, not an illusion
You can keep saying science can't study and prove that headaches are an actual real medical symptom, but it won't make it any more true
I'm going to ask you this once again until you actually answer the question that's being asked to you
Yes or no?
Meaning:
If you are 100% sure you're seeing water (meaning, if you were asked at the moment if you "think" you're seeing water, you would answer "No. I don't think I'm seeing water. I know I'm seeing it. It's real, drinkable water), only to later find out as you walk further that you were wrong, that it wasn't actually water, that it was nothing but a mirage, even though at the previous moment you "knew" what you were seeing water. Do you in other words accept that perception is erroneous and leads to false beliefs, no matter how convincing they are? That believing that things are real because "you are one hundred per cent that what you're perceiving is real" is a dishonest approach based on wishful thinking?
