Professor Tadeusz Kowalik (1926-2012) was the most outstanding Polish economist of social-democratic convictions in the post-1989 period. In the very first issue of WFES [vol. 1, no 1 (1)] we published his significant paper pertaining to the relation between economy and sociology (Is Cooperation of Sociologists and Economists Possible and if so When?). In the preface to the previous issue [vol. 3, no 1 (5)] we announced an article containing a synthetic presentation of Professor Kowaliks most essential views on political economy featured in selected works published in his final years. In this issue of WFES we hold our word and deliver the article as promised.
