It’s like battleship, but more words and usually fewer boats

Dialog:

• Attack
  • Port - Isn't it ridiculous to suggest that possible worlds exist?
• Counterattack - returns fire with another question.
  • Starboard - People believe sets of numbers exist without too much trouble, why not sets of possibilities?
• Counterattack – or you could call it a “counter-counterattack”
  • Port - But, don't numbers "exist" in a different sense than you or I do?
• Hit - The Clarification Question, to respond one often must sacrifice the offensive.
  • Starboard - Are you arguing that numbers require the mind in order to exist?
• Note: Resorting to a vacuous counterattack like "what do you think?" is equivalent to surrender.
• No matter how sassy you are able to make it sound.
