Now the good of political life is a great political good. It is not a secular good specified by a comprehensive doctrine like those of Kant or Mill. You could characterize this political good as the good of free and equal citizens recognizing the duty of civility to one another: the duty to give citizens public reasons for one's political actions.

An intolerant sect has no right to complain when it is denied an equal liberty... A person's right to complain is limited to principles he acknowledges himself.

Justice is happiness according to virtue.

Citizens can have their own grounding in their comprehensive doctrines, whatever they happen to be.

An intuitionist conception of justice is, one might say, but half a conception.

At best the principles that economists have supposed the choices of rational individuals to satisfy can be presented as guidelines for us to consider when we make our decisions.

Different political views, even if they're all liberal, in the sense of supporting liberal constitutional democracy, undoubtedly have some notion of the common good in the form of the means provided to assure that people can make use of their liberties, and the like.
