We know hardly anything about anything.

We still do not know one thousandth of one percent of what nature has revealed to us

We can never know anything.

All we can know is that we know nothing. And that's the height of human wisdom.

The only thing that we know is that we know nothing — and that is the highest flight of human wisdom.

The only thing I know is that I know nothing, and i am no quite sure that i know that.

Nothing has been discovered, nothing has been invented. We can only know that we know nothing. And that's the highest degree of human wisdom.

Never knowing
Shocking but we're nothing
We're just moments
We're Clever but we're clueless
We're just human
Amusing but confusing
But the truth is
All we got is questions
We'll Never Know.

I know nothing except the fact of my ignorance.

The Only Thing I Know For Sure Is That I Know Nothing At All, For Sure

Our discreditable secret is that we don't know anything at all, and our horrid inner secret is that we don't care that we don't.

However closely we live together, at whatever time of day or night we sound the deepest thoughts in one another, we know nothing.

One thing only I know, and that is that I know nothing'.

I cannot discover that anyone knows enough to say definitely what is and what is not possible.
