Abstract: Is it self-interest or public interest that dominates in public life? Rational-choice theory, political philosophy, and electoral research were all used to answer this question. Analysing existing literature, Professor Leif Lewin shows that predominant consensus emerged on this issue by the 1980s. This consensus states that people in politics are driven mostly by their self-interest and not by common good and society values. Although Professor Lewin is not testing existing views that ‘egoism rules’ on deep theoretical grounds, he strongly argues that empirical facts do not support such views and thus opens a new chapter in the debate on individuals’ rationality.Combining research results and achievements of different research fields, mentioned above, the author adopts methodology never used before. Extensive literature review on studies of Western democracy provides a basis for analysis for many countries. Separate chapters of the book are devoted to the attitudes and actions of the electoral voters, politicians, and bureaucrats in power.This allows the author to make broad conclusions, which challenges predominant views. He concludes that in most cases people in politics are driven by broader social interests rather than their own short-term interests.
