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!
