Is it really better to know nothing or to know that we know nothing, if true knowledge is found in realising that we know nothing?

Knowing nothing isn't being born in a cave and never learning anything. Therefore you have a clean mind that knows nothing.

Knowing nothing is that no matter what you may have heard, learned or read, it is all irrelevant to you because you yourself doesn't actually know. Therefore you always know nothing.

Then regardless of everything you know, you have to know that you know nothing.

Being told anything, still means you know nothing.

So it isn't a question of which is better. The truth is you do know nothing, whether you like it or not. But do you know that you know nothing.
