• ⚖️ The four forms of hypothetical syllogism include affirming and denying antecedents and consequents.
• 🆚 Disjunctive syllogism presents alternatives, with the conclusion following from rejecting one of the options.
• 📊 Dilemmas mix hypothetical and disjunctive syllogisms, presenting challenging scenarios for debate.
