So it seems 2

In a materially based world view it seems we can accept one-sided truths.
It seems quite correct to say, when we see a house: It is a house.
But this is an one-sided truth. The other side of the truth is: "This building is in decay".
The house might stand for decades, so if we look at the material facts it is acceptable to see it as a house.
On the mind level, however, the decay of the building is going on all the time. If the house still stands there 30 years from now it is probably practically a new house, with new roof, new walls, new paint, new heating system and so on.
On mind level, the stability of material reality is not present so we see reality as a process in constant change.
If we know about this change, we can not accept temporary and adventitious observations as basis for our decisions. We want the full picture, including all ups and all downs.
