What is the theme in A Theory of Justice by John Rawls?

Another theme is the Individual versus society. A central concern in defining a just society is always in regard to the potential for conflict between the interests of the individual and the interests of society as a whole. Rawls points out that the individual must be granted the maximum liberty, but only insofar as it does not have a negative effect on the liberties of others. He asserts that a central flaw in the theory of utilitarianism is that it assumes the benefit to a majority can justify restrictions on the liberties of any individual or group of individuals.
