He Who Knows Not

He who knows not

and knows not that he knows not

is a fool

shun him

 

He who knows not

and knows that he knows not

is a child

teach him

 

He who knows

and knows not that he knows

is asleep

wake him

 

He who knows

and knows that he knows

is wise

follow him

 

 

I have no idea whose words these are nor when/where I learned them.  Anyone who does, please let me know.
