The first principle states that each person has an equal right to the most extensive basic liberty compatible with a similar liberty for others. The second principle focuses on social and economic inequalities, stating that they should be arranged so that they are both to the greatest benefit of the least advantaged and attached to positions and offices open to all under conditions of fair equality of opportunity. These principles are meant to ensure that all individuals have equal access to basic liberties and opportunities, and that any inequalities in society are structured to benefit the least advantaged. **
