Contractualism
Asks which principles people can justify to one another, especially whether a principle could be reasonably rejected by someone it affects. Individual claims matter in the justification of shared rules.
Foundational doctrines
- Mutual justification
- Reasonable rejection
- Equal moral standing
Disagreement and variation
Reasonable rejection is not identical to bargaining advantage or majority preference; disputes concern how competing individuals’ reasons should be compared. Scanlonian contractualism differs from bargaining-based contractarianism. General duty and equality answers do not establish either theory.
