R38 1999 </Td> </Tr> <P> A Theory of Justice is a work of political philosophy and ethics by John Rawls, in which the author attempts to solve the problem of distributive justice (the socially just distribution of goods in a society) by utilising a variant of the familiar device of the social contract . The resultant theory is known as "Justice as Fairness", from which Rawls derives his two principles of justice . Together, they dictate that society should be structured so that the greatest possible amount of liberty is given to its members, limited only by the notion that the liberty of any one member shall not infringe upon that of any other member . Secondly, inequalities either social or economic are only to be allowed if the worst off will be better off than they might be under an equal distribution . Finally, if there is such a beneficial inequality, this inequality should not make it harder for those without resources to occupy positions of power, for instance public office . </P> <P> First published in 1971, A Theory of Justice was revised in both 1975 (for the translated editions) and 1999 . </P>
