The more I learn, the more I realize how much I don't know.

All I know is that I do not know anything

I only know that I know nothing

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

I am tired of knowing nothing and being reminded of it all the time.

I know one thing: That I know nothing,

I know nothing except the fact of my ignorance.

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

Je sais que je ne sais pas ce que je ne sais pas.

I know nothing.

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

I know that I am intelligent, because I know that I know nothing.

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

Sólo sé que no sé nada.
