Principles of Justice
(Section 11)
First Principle: Liberty
Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with a similar system of liberty for all.
Second Principle: Wealth
Social and economic inequalities are to be arranged so that they are both:
(a) to the greatest benefit of the least advantaged, consistent with the just savings principle, and
(b) attached to offices and positions open to all under conditions of fair equality of opportunity.
Representative persons: prototypical members of any identifiable group (e.g., women, high school students, citizens of Haiti, etc.).
Efficiency: any re-arrangement in which every representative person gains is more efficient.
Difference principle: in order for any change to be accepted as an improvement, it must help the least advantaged representative person.
