Modal logic is special because it uses statements that are qualified with expressions like “necessarily”, “possibly”, or “sometimes.”
Starboard:
1) Modal logic solves some problems.
2) In a complex modal argument many will naturally expand at least one claim beyond reason.
3) When claims are irrationally expanded many will accept an unreasonable conclusion.
4) Therefore, numerous people are likely to accept the conclusion of a complex modal argument.
5) Convincing people is the largest obstacle to solving problems.
6) Therefore, modal logic can solve all problems.
