Oh, I see that you did attempt to do this above. It failed abysmally.
There was more sky-daddying and cod psychology of the sort that suggests you have some sort of inferiority complex. And I assume that by 'word salad' you mean to express that you could not follow the relevant section?
Anyway, ignoring all that, what do we find? Well, not exactly high brow stuff.
why do you keep humping this concept that knowledge has to have justified true belief? you keep bringing up justified true belief. — MAYAEL
Er, it's just what knowledge involves. It was first articulated by Plato. There's dispute over whether knowledge involves more than this - whether there is another ingredient - but there isn't serious dispute over whether it involves possessing a justified true belief. There's a debate over whether you need to be aware of the justification in question and there are debates over the mechanics of how you need to have arrived at a belief in order for it to count as justified in the right kind of way - debates prompted by Gettier's famous article. But that it involves true belief and justification is not in dispute. And that's all my argument requires.
obviously I'm not sure what the confusion there was. perhaps people misunderstood you in thinking you said you owned all Rembrandt's and nothing else? — MAYAEL
Yes. That is, they were being stupid (well, if they'd dared to answer - they didn't, presumably because they were foxed by it). If I say "if I own all the world's Rembrandt paintings, do I own any fake Rembrandts? Yes, no, or maybe?" and someone doesn't know the answer or thinks it is something other than 'maybe', then they are, well, just dumb, at least on that occasion (everyone has bad days, of course).
For instance, that same person would no doubt think this argument valid:
1. If P, then Q
2. Q
3. Therefore P.
Whereas it is not. This is:
1. If and only if P, then Q
2. Q
3. Therefore P
Someone who cannot distinguish between 'if P then Q' and 'if and only if P, then Q' is just not that good at philosophy becuase they're impatient and sloppy and don't care about important distinctions.
Now, obviously I am pleasantly surprised that you recognize that if I own all the world's Rembrandts, that leaves open the possibility that I may also own some fake Rembrandts. Well done! Give yourself a big macho pat on the back. Hang on, I'll try and talk bloke: "Alwight mate!! Nice one!" No, that's all I've got.
Now apply that to knowledge: if I am in possession of all the world's justified-true-beliefs (Rembrandt paintings), do I have any false beliefs (fakes)? Yes, no, or maybe?
The answer is maybe.
A clever person might object that this may not be the case - that the answer could be a decisive 'no' - because if you have a false belief, then there's a true belief you lack. And they may think that if you are in possession of all items of knowledge, then you are eo ipso in possession of all true beliefs. And thus your possession of all true beliefs precludes you having any false ones.
But that's why I started by demonstrating how possessing all the world's knowledge is compatible with not being in possession of all the world's true beliefs. (I think my fictional critic's claim is dubious anyway, but rather than bother exploring it I can just sidestep it with the move I made).
So, step one: show that having all-knowledge does not necessarily involve having all the world's true beliefs. That's what the pizza example showed. Knowledge has at least two components, and thus having all knowledge is akin to having all the world's pizzas. But if one has all the world's pizzas one does not necessarily have all the world's pizza bases, for a pizza base without a topping is not a pizza and thus not necessarily something one owns.
Thus, having all knowledge is compatible with not having all the world's true beliefs.
With that in the bank, the way is now clear to show that having all knoweldge is compatible with having some positively false beliefs. That was step two.
And then I showed that God positively would have some false beliefs, such as believing that he is not God.
