Do you really know what you know,
There is something called The Matrix Possibility. We can't REALLY know what we think we know based on the POSSIBILITY our beliefs are false knowledge.
Morpheus: What is real? How do you define real? If you're talking about what you can feel, what you can smell,
what you can taste and see, then real is simply electrical signals interpreted by your brain.
There are two different senses of "knowledge." One is super knowledge. You can't super know anything unless there is absolutely no possibility whatsoever you have it wrong. The other is ordinary knowledge where you can admit you're possibly wrong about something but not probably wrong. It's not possiblity that matters the most, it's the probability. So until someone can give me a very good reason to think my belief is not just possibly false, but probably false, I'm not changing anything about what I think I know.
