I get you now. And this is fine so long as the outcome really doesn't matter.
I'm not sure what you mean by outcome. I don't see knowledge as necessarily requiring any outcome as much knowledge involves a journey of discovery that we are still on with no outcome yet in sight.
If you are sitting in a seat on an airliner about to take off from New York to London, don't you think the fact the pilot can demonstrate his knowledge there is sufficient fuel to make the trip is a bit important? If you are about to grab an exposed electrical wire, wouldn't you think your ability to demonstrate it isn't live might impact your future in some way? If there is no outcome to this claim of knowledge, then I suppose it really doesn't matter whether you can demonstrate it or not. But that is often not the case. When it matters, you need to be able to demonstrate.
Sigh. I thought we had reached an understanding of the difference between demonstrability and knowledge that is not demonstrable.
Unless you witnessed or participated in the fueling of the airplane and have the knowledge to know how much fuel is required to go X miles under X conditions, you are taking on pure faith that there is sufficient fuel to get you to your destination or that the plane is capable of utilizing it and getting you there for that matter. The ONLY way the pilot could DEMONSTRATE that to you is by removing the fuel, showing it to you, and then have you watch him put it back into the plane and then in fact flying you to your destination.
The pilot's testimony about the fuel is a form of evidence and, if you trust the pilot to give you accurate information about that, it will be considered credible evidence.
You possess both knowledge and evidence that it is likely, within a high degree of mathematical probability, that the airplane will take you safely to your destination. But there is no way to demonstrate that until the flight happens.
There is no telescope capable of allowing us to see planets in other solar systems. Scientists deduct they are there via differentiations in light emitting from other solar systems. That is both scientifically calculated and definitely a form of evidence of what they conclude are planets that exist out there, and it is knowledge. But we have absolutely no way to DEMONSTRATE that they are in fact identifying planets by that method.
No. We have not reached an understanding. There is a difference between my not demonstrating my knowledge to you and my being unable to demonstrate it, which is what I believe you meant with Aristotle. So long as the knowledge itself is of no real consequence, this is fine. But if it matters, then it must be demonstrable. You can think you know about God without demonstrating it because it just doesn't matter, but you have to demonstrate you know how to operate a car to get a license, because that does.
Okay. So we don't have an understanding. I know a great deal of knowledge that is of major, even critical, consequence that I cannot demonstrate to a single other soul and so do you. But some are unable to grasp the concept I guess. I won't accuse you of being in the deliberately obtuse and intentionally disruptive group, but I gave the explanation my best shot. I don't know if the failure to understand is in your inability to understand or whether I am a shitty teacher. But either way we tried.
Oh no. I grasp the concept. I really do. I just think you're wrong.
