Bertolt Brecht - My young son asks me...

My young son asks me: Must I learn mathematics?
What is the use, I feel like saying. That two pieces
Of bread are more than one's about all you'll end up with.
My young son asks me: Must I learn French?
What is the use, I feel like saying. This State's collapsing.
And if you just rub your belly with your hand and
Groan, you'll be understood with little trouble.
My young son asks me: Must I learn history?
What is the use, I feel like saying. Learn to stick
Your head in the earth, and maybe you'll still survive.

Yes, learn mathematics, I tell him.
Learn your French, learn your history!

Bertolt Brecht
