Abstract
One of the points of interest of A Theory of Justice was that it tied so tightly together efficiency and equity; however, this link was entrusted to the "principle of difference" and the related maximin rule, the very point that is dropped in this book. Now society as a cooperative enterprise becomes part of the shared concept of the just society and it is no longer the reason for its justification; on this basis, however, Rawls lucidly asks the question about the justification for solidarity with those suffering from such severe handicaps to prevent then from making a contribution to this cooperative enterprise. His answer is that for the problems to which justice such as
equity does not give an answer there are several possibilities: one is that the idea of political justice cannot cover everything and that we should not expect it to; or the problem may be a problem of political justice, but justice as fairness does not would be the correct conception in this case, though it may be in other cases.
