My belief that there is a television in my living room right now is fully justified by
seeing a television in my living room right now.
This remains true if I am a brain in a vat, hooked up to a computer. When-so-ever
a set of what appears to be physical sensations correctly maps to the elements of

This only leave analytical knowledge. Analytical knowledge is a set of mutually self-defining
semantic tautologies. https://www.britannica.com/topic/tautology
If PROOF for a statement IS NOT YET KNOW, then 'that statement' COULD BE 'true'. That is; if PROOF for 'that statement' being 'False' IS NOT KNOWN.
In other words, ANY statement can only be Truly JUSTIFIED WITH ACTUAL PROOF.
'BELIEF' of or for absolutely ANY 'thing' is completely REDUNDANT here, and is BEST left OUT OF 'the equation', altogether.
Also, even if 'we' REALLY were 'brains in vats', then this does NOT mean that 'physical reality exists if false' AT ALL. In fact if 'we' REALLY were 'brains in vats', then this ACTUALLY MEANS that 'physical reality' ACTUALLY DOES EXIST.

WORK 'this' OUT, and then you WILL BE CLOSER to SEEING and UNDERSTANDING what the ACTUAL and IRREFUTABLE Truth of 'things' REALLY IS.
