How do humans know they know?

They don't, they can only assume. __________________ Assuming is a kind of knowing. We know that we know because we ask. Asking is a kind of knowing as well. Not knowing how to know, humans can not even know, That They Don't Know.

When this finally dawned on Cause, cause of all things and happenings he had the prophet Paul advise man of this, so he would know, and do something about it for himself! for Where ignorance is bliss; 'Tis a folly to be wise!

Let no man deceive himself if any man among you seemeth(thinks himself) to be wise in this world, let him become(admit to being) a fool, that he may become wise. For the wisdom of this world is foolishness with God. For it is written he taketh the wise in their own craftyness. [I CORINTHIANS 3:18-19.]

But humans never listened, nor followed the advise. Sometimes it is necessary to get a stubborn mule's attention! For it is written he taketh the wise in their own craftyness!

That prophesy was fulfilled 9/11/01.

When man crafted airplanes demolished the trade center, and damaged the Pentagon, carrying out this commandment.

Pass through the land as a river, O daughter of Tarshish; there is no more strength. He stretched out his hand over the sea, he shook the kingdoms; the "Lord" hath given a commandment; against the MERCHANT CITY, to destroy the strong holds thereof, [ISAIAH 23:10-11.] Do you realy think Newton explained the power of "Cause"!
