Alright, I thought I was done in this thread, but apparently all that means is I'm going to get ridiculed. Apparently I did a poor job of getting myself across.
Roger, at no point, in any of my posts, have I disagreed with or corrected anything you said in the OP. I'm not arguing that how someone perceives reality changes it. What I was attempting to do is contribute to the thread, constructively, which I am still hoping can be done.
So I will try again:
Reality, as Roger stated, is not subjective. I agree with that, and stated so in my posts. Perceptions of reality, whether you want to call them reality filters or grids, are subjective.
So at the end of the OP, Dok states that a fundamental error people make about this is that it somehow doesn't apply to themselves. I was arguing that this is true, and adding that people also mistake their perception of reality for reality itself. This doesn't change reality because as has been established, reality is not subjective. But when people think that their screwy grids are the non-subjective reality, it becomes a trap.
That is really all.
