2. I begin by stating a problem about understanding Mill. In many of
his writings, Mill states certain principles which he sometimes calls “the
principles of the modern world.” These principles we can think of as princi-
ples of political and social justice for the basic structure of society.
2
I will be
discussing these principles in some detail in the next two lectures, when we
take up the essays On Liberty and The Subjection of Women; but suffice it to
say here that Mill thinks them necessary to protect the rights of individuals
and minorities against the possible oppression of modern democratic ma-
jorities (On Liberty, Chapter I).
Now I believe that the content of Mill’s principles of political and social
justice is very close to the content of the two principles of justice as fair-
ness.
3
This content is, I assume, close enough so that, for our present pur-
poses, we may regard their substantive content as roughly the same. The
problem that now arises is this:
How does it happen that an apparently utilitarian view leads to the
same substantive content (the same principles of justice) as justice as fair-
ness? Here there are at least two possible answers:
(a) Perhaps these principles of political justice can be justified—or ar-
rived at—within both views, so that both support these principles much as
they would in an overlapping consensus.

In the Restatement, I said that the
parties in the original position, selecting principles for the basic structure,
might be viewed as using what I called a utility function based on the fun-
damental needs and requirements of citizens conceived as free and equal

hereafter cited as Restatement.
2. A society’s basic structure consists of its main political and social institutions and
the way they hang together in one system of cooperation (Restatement, pp. 8f ).
3. The two principles of justice as fairness are: (a) each person has the same indefeasi-
ble claim to a fully adequate scheme of equal basic liberties, which scheme is compatible
with the same scheme of liberties for all; and (b) social and economic inequalities are to
satisfy two conditions: first, they are to be attached to offices and positions open to all un-
der conditions of fair equality of opportunity; and second, they are to be to the greatest
benefit of the least-advantaged members of society. This last is called “the difference prin-
ciple.” Some writers prefer the term “maximin principle,” but I prefer the difference princi-
ple, to distinguish it from the maximin rule for decision under uncertainty (Restatement,
pp. 42f ).
4. An overlapping consensus is a consensus in which the same political conception of
justice is endorsed by the reasonable, though opposing, religious, philosophical, and moral
doctrines that gain a significant body of adherents and endure from one generation to the
next (Restatement, p. 32 and p. 184).
