The history of logic in Central and Eastern Europe is still known to very few people. Hardly anybody knows about logical traditions in Russia, Serbia, Hungary, Czech Republic, Bulgaria, while much fewer people know about logical traditions in Bosnia and Herzegovina, Macedonia, Montenegro. As an exception to the rules only two scientific brands have become internationally popular: the Vienna Circle, associated exclusively with Austrian logicians, and the Lvov-Warsaw School, associated with Polish ones. Nevertheless, the countries included in this region have not only the joint history, but also the joint cultural dynamics. This paper shows a social context of logic in this region. The paper consists of excerpts from the Introduction of the book ‘Logic in Central and Eastern Europe: History, Science and Discourse’ (University Press of America) edited by the author.
