Thanks for that answer. It seems so simple I don't know how I could've missed it.

I think you were saying that by gaining new perspective I call into question my old beliefs, breaking them down and even stripping them away. And that through this process I lose some sense of "intellectual stability" or something like that? I'm not sure if this is what you meant, but it's what I was sort of thinking before reading any answers.

A few things I've read are Plato's republic, a couple philosophy textbooks, some work by Henry David Thoreau, philosophic dictionary by Voltaire and I've started a couple more.
Though, mostly I just search Google and YouTube for articles, essays, lectures, debates and other related info.
