If you marry, you will regret it; if you do not marry, you will also regret it; if you marry or do not marry, you will regret both; Laugh at the world’s follies, you will regret it, weep over them, you will also regret that; laugh at the world’s follies or weep over them, you will regret both; whether you laugh at the world’s follies or weep over them, you will regret both. Believe a woman, you will regret it, believe her not, you will also regret that; believe a woman or believe her not, you will regret both; whether you believe a woman or believe her not, you will regret both. Hang yourself, you will regret it; do not hang yourself, and you will also regret that; hang yourself or do not hang yourself, you will regret both; whether you hang yourself or do not hang yourself, you will regret both. This, gentlemen, is the sum and substance of all philosophy.
