Przyczynek do analizy zdań egzystencjalnych

The editors of Stanisław Leśniewski's „Collected Works” inserted into the book an English translation of the Polish original of „A Contribution”. The Russian version of this text, published by Leśniewski in the „Logical Studies”, differs from the original in quite a few important fragments. The Polish original, reprinted here, contains all the modifications introduced into the Russian version. The main thesis of Leśniewski's paper is that all existential propositions are either analytic or self-contradictory.
