I alone know I am wise because I alone know I know nothing.
Wisest is he who knows he knows not.
I shall never fear or avoid things of which I do not know...
Wisdom is knowing when you don't know
All that we know is nothing can be known.
As for me, all I know is I know nothing.
I am a fool, but I know I'm a fool and that makes me smarter than you.
I know nothing but the certainty of my own ignorance.
All that I know is nothing - I'm not even sure of that.
I know what I do not know.
You don't know what you don't know.
You will know that the divine is so great and of such a nature that it sees and hears everything at once, is present everywhere, and is concerned with everything.
I only know one thing, and that is I know nothing
I only know how little I know
The more I know, the more I know that I don't know.
All I know is that I do not know anything
I know one thing, that I know nothing.
I know that I know nothing.
I only know that I know nothing
The more I learn, the less I realize I know.
To know thyself is the beginning of wisdom.
To know, is to know that you know nothing.
Wisdom is knowing what you don't know.
