Again, you have gone off on a tangent from the original statement (emboldened). Do you believe everything you typed about Christians and Muslims? Is your belief (only knowledge if it can be verified and justified as true) based on the verification of facts as they really are (is it a true account)? Only if you can demonstrate this with certainty (truth is a certainty - it expresses what is, it cannot be false), will I grant you know it as true?
First, what is your standard or ultimate measure in qualifying what is "good?"
There is no tangent: at best, you/anyone could only ever "believe" I, or any, know what we know. As to whether or not you know what you know, you are your own obstacle to that, not me. I know Christians and Muslims suffer "belief"-based ignorance. I know this because I tried/tested both Christianity and Islam and found them to be certainly ignorant. Again: at best, you can only "believe" me that I know, but I myself know I know. I can't prove something to someone who has no conscious knowledge that they may themselves be subject to "belief"-based ignorance(s) unto which they vehemently cling to. It has to do with idol worship (not "physical objects").
As to your second question: your very asking it demonstrates you are ignorant of the problem-in-and-of-itself:
But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
...first, what is your standard or ultimate measure in qualifying what is "good?"
I don't eat from that tree. Those who do, have a relative "evil" and are bound to be in conflict indefinitum. If you know, at best, one could only ever "believe" to know good and evil, the very "believing" to know it causes suffering and death. Say hello to "belief" in any god.
By the way, does it not take a "believer" to "believe":
i. Belief-in-and-of-itself is a virtue (?)
ii. evil is good (*without the need to define them*)
iii. satan is god
Who are so willing to believe?
0- I am (willing to)...
3 (*not to*)
Living: I am willing to KNOW (any/all / *not to*) BELIEVE...
Death: I am willing to BELIEVE (any/all / *not to*) KNOW...
Would an all-knowing god not KNOW so-called satan *requires* BELIEF-in-and-of-itself?
Knowledge-in-and-of-itself <-*tends towards any possible all-knowing god any/all *not* to believe
Belief-in-and-of-itself <-*satan certainly requires belief
Ignorance-in-and-of-itself <-*believers who believe evil is good cause suffering/death
Is knowledge of ones own ignorance not needed to beget new knowledge *from* the same ignorance(s)?
If so, how can all knowing be belief, if belief is required to (erroneously) believe one is knowing when one is not?
Does it takes a "believer" to "believe" they are themselves *not* ignorant?
Does it thus take a "knowing" to "know" one is themselves ignorant?
What happens if one is ignorant while knowing not they are ignorant?
They are certainly a "believer" and ignorant-in-and-of-themselves.
Do you believe everything you typed about Christians and Muslims?
No: I know they are ignorant-in-and-of-themselves. However, I do not "blame" them: I see them as victims.
That is why if I ever undermine the idolatrous houses of Christianity/Islam, I'd do it from the top-down. The "believers" do not know what tree they eat from.
