How do pain and pleasure define each other?

Some things are only fully understood through their relationship with their opposite. The presence of their opposite defines their meaning — in part or whole.

• What is pleasure if you don’t know pain?
• What is happiness if you don’t know sadness?
• What is winning if you don’t know losing?
• What is freedom if you don’t know restriction?
• What is confidence if you don’t know doubt?
