try hard to keep your memories accurate.

Do what seems logical to you. This will manifest to people throughout the world in different ways because we are raised differently but its the best we got to knowing truth.

For example, I was raised Christian and accept a form of the Christian doctrine as being true. I know of arguments for and against the religion, but the way I understand the religion seems logical enough to me for to be an accurate estimation of truth. This acceptance brings order to a chaotic universe, purpose to an disorderly existence and meaning to our lives as humans. If I was raised in Saudi Arabia, I'd probably be Muslim. If I was raised in Japan I might be Buddhist. But because I've been raised Christian and understand Christianity better than all those religions I've accepted in a form that appears logical to me.

>It seems like your selection of which fundamental beliefs to accept- whether or not the mind can really understand its surroundings as they are and not as they perceive it could be one, maybe- would probably be decided on based on even more arbitrary factors that would rely on assumptions.
The arbitrariness assumes you aren't where you are for reason. A lot of belief systems (mine included) don't think this is the case.
