In the paper "Kotarbiński's Theory of Genuine Names", which was published recently in this journal¹, I attempted to sketch and explain a theory of genuine names formulated by Tadeusz Kotarbiński, who is perhaps Poland's outstanding 20th century philosopher. The theory is a fundamental ingredient of Kotarbiński's nominalistic views, and it marks a development of nominalism and nominalistic semantics generally unknown to philosophers and semanticists of the West. The theory also reveals how some of the logical concepts of Stanisław Lesniewśki, one of the leading members of the Warsaw School of logicians which flourished between the two Wars, influenced the development of a nominalistic metaphysics — Kotarbiński's reism.
