Is true that, that type of house is always in reparation?

This, we can't access absolute truth, but we can get some chunks of it.
Maybe there is no table in front of me, maybe my brain is hallucinating, but there is something that make my brain see the table. The table that i see its a representation of something real.
Back to the post, there is objective knowledge. This type of knowledge is discovered, no made it up.
