11. TWO PRINCIPLES OF JUSTICE
I shall now state in a provisional form the two principles of justice that I believe would be chosen in the original position. [...] The first statement of the two principles reads as follows.
First: each person is to have an equal right to the most extensive basic liberty compatible with a similar liberty for others.
Second: social and economic inequalities are to be arranged so that they are both (a) reasonably expected to be to everyone's advantage, and (b) attached to positions and offices open to all.
[...] The basic liberties of citizens are, roughly speaking, political
liberty (the right to vote and to be eligible for public office) together
with freedom of speech and assembly; liberty of conscience and freedom
of thought; freedom of the person along with the right to hold (personal)
property; and freedom from arbitrary arrest and seizure as defined by the
concept of the rule of law. These liberties are all required to be equal
by the first principle, since citizens of a just society are to have the
same basic rights.
The second principle applies, in the first approximation, to the distribution of income and wealth and to the design of organizations that make use of differences in authority and responsibility, or chains of command. While the distribution of wealth and income need not be equal, it must be to everyone's advantage, and at the same time, positions of authority and offices of command must be accessible to all. One applies the second principle by holding positions open, and then, subject to this constraint, arranges social and economic inequalities so that everyone benefits.
These principles are to be arranged in a serial order with the first principle prior to the second. This ordering means that a departure from the institutions of equal liberty required by the first principle cannot be justified by, or compensated for, by greater social and economic advantages. The distribution of wealth and income, and the hierarchies of authority, must be consistent with both the liberties of equal citizenship and equality of opportunity.
[...] For the present, it should be observed that the two principles (and this holds for all formulations) are a special case of a more general conception of justice that can be expressed as follows.
All social values - liberty and opportunity, income and wealth, and the bases of self-respect -are to be distributed equally unless an unequal distribution of any, or all, of these values is to everyone's advantage.
Injustice, then, is simply inequalities that are not to the benefit
of all. [...]
24. THE VEIL OF IGNORANCE
The idea of the original position is to set up a fair procedure so that
any principles agreed to will be just. The aim is to use the notion of
pure procedural justice as a basis of theory. Somehow we must nullify
the effects of specific contingencies which put men at odds and tempt them
to exploit social and natural circumstances to their own advantage.
Now in order to do this 1 assume that the Parties are situated behind a
veil of ignorance. They do not know how the various alternatives will affect
their own particular case and they are obliged to evaluate principles solely
on the basis of general considerations.
It is assumed, then, that the parties do not know certain kinds of particular facts. First of all, no one knows his place in society, his class position or social status; nor does he know his fortune in the distribution of natural assets and abilities, his intelligence and strength, and the like. Nor, again, does anyone know his conception of the good, the particulars of his rational plan of life, or even the special features of his psychology such as his aversion to risk or liability to optimism or pessimism. More than this, I assume that the parties do not know the particular circumstances of their own society. That is, they do not know its economic or political situation, or the level of civilization and culture it has been able to achieve. The persons in the original position have no information as to which Generation they belong. These broader restrictions on knowledge are appropriate in part because questions of social justice arise between generations as well as within them, for example, the question of the appropriate rate of capital saving and of the conservation of natural resources and the environment of nature. [...]
As far as possible, then, the only particular facts which the parties know is that their society is subject to the circumstances of justice and whatever this implies. It is taken for granted, however, that they know the general facts about human society. They understand political affairs and the principles of economic theory; they know the basis of social organization and the laws of human psychology.
[...] the original position is not to be thought of as a general assembly which includes at one moment everyone who will live at some time; or, much less, as an assembly of everyone who could live at some time. It is not a gathering of all actual or possible persons. To conceive of the original position in either of these ways is to stretch fantasy too far; the conception would cease to be a natural guide to intuition. [...]
