Papyrus
Really though! That human! Do I know that person?

Sans
Do you not know who you know?

Papyrus
Of course I know who I know! I wanted to know if you know I know who I know as much as I know I know who I know! You know?

Socrates
But how do you truly know you know you know who you know?

Papyrus
What?

Socrates
You claim to have knowledge about knowing who you know. How can you be certain of that knowledge?

Papyrus
I should know, shouldn't I?

Socrates
Let us see. Do you believe that you are aware of which things you know?

Papyrus
Of course! I know what I know because I know.

Socrates
But what of false beliefs? Are they too a kind of knowledge?

Papyrus
Hmmm. Well, if they're not true, then I don't know them. I just think I know them.

Socrates
Then you do not know which things you know, because the belief in knowing some of them is false.

Papyrus
But I don't actually know the things I think I know but don't know, don't I?

Socrates
Indeed.

Papyrus
Aha! So if I don't know the things I think I know but don't know, then I do know I know all the things I do know!

Socrates
It is as you say that you should know about all your true beliefs. In that same way, a good playwright should know what makes a good play, and a cook should know whether a meal is good.

Papyrus
That's true.

Socrates
Would you agree that is how they can be said to know plays, and to know meals?

Papyrus
Yes.

Socrates
And would a playwright who knows plays recognize a bad play, or a cook who knows food recognize a bad meal?

Papyrus
Ah! You're saying that to know what I know I need to know what I do not know, not just what I do know!

Socrates
That is it exactly. To be a good playwright requires to be able to distinguish between good plays and bad plays. And a good cook should know the difference between good meals and bad meals. And to be wise, one needs to tell apart good beliefs and bad beliefs. One needs to know what one does not know as much as what one does know.

Papyrus
Yes! But! Now that we know how to know whether we know what we know, we still don't know whether you can solve this puzzle!

Sans
Hey, thanks. I think my brother likes having someone to talk to.
