There is constant debate around the questions of what constitutes the 'just' distribution of goods and how we can assess existing distribution patterns. Some commentators mistakenly believe that there can be one simple, all-encompassing governing principle that automatically yields the 'fairest' results. In this book Grzegorz Lissowski argues that three types of principles need to be distinguished according to three requirements ofjustice: equality, impartiality, and unanimity.The principle of equality regulates the results of the division of goods; impartiality concerns the characteristics of the method applied; unanimity the mutual agreement of all parties involved in the division. A thorough examination of the properties of these principles of justice allows for a rational choice of the principle that is suited best to any given situation.Each chapter is written in two parts, the first offering an general overview suitable for any interested reader, the second – marked with an asterisk – for those interested in the more detailed justifications of arguments brought forward.Lissowski’s book presents and systematises the results of studies about various aspects of the division of goods, carried out over the past forty years. The work is unique in the world literature because of the key idea of linking division principles with three of their aspects: equality, impartiality, and unanimity.Prof. Tadeusz KrauzeHofstra University, New YorkLissowski sums up his many years of research, and he reaffirms his strong position in the international literature which he has achieved by publishing several articles in renowned American journals (e.g. American Political Science Review).Prof. Piotr SztompkaJagiellonian UniversityGrzegorz Lissowski is sociology professor at the University of Warsaw.
