Classical references in modern literature often annoy me. Not the type of references where we learn about a character, but the type that require one to know some character from the Iliad (for example) to understand the piece as a whole.
Socrates would say that
The wise man is he who knows that he does not know,
Although whether he truly knew this or not is uncertain.
Protagoras would say that we cannot know anything,
So we cannot even know that we do not know
Heraclitis would say that everything changes,
For now we know nothing, but who knows what it will be like tomorrow?
Leonard Cohen would say ‘my name is Theodotus’,
And I can almost forgive him.
