In this paper I present Bertrand Russell’s contacts with Polish readers and outstanding Polish writers. In paragraphs 2 and 3 I discuss books by Russell that were published in Poland and mention his personal contacts and correspondence. Russell exchanged letters with L. Chwistek, J. Conrad‑Korzeniowski, M. Dziewicki, G. Herling-‑Grudziński, S. Leśniewski, W. Lutosławski and A. Tarski. Interesting comments on his philosophy were offered by M. Ossowska, K. Twardowski, J. Salamucha and M. Heitzman. Paragraphs 4 and 5 discuss the influence that Russell’s logical ideas have exerted on the development of logic in Poland, especially in the works of L. Chwistek and S. Leśniewski.

In this paper, I present a short 10-point characteristics of the classical conception of truth. Subsequently I point to the importance and comprehensive usefulness of this truth, among others, to the possibility of applying it in some virtual environments, e.g., in those which include virtual objects of types A and C. I also emphasize that—independently of views of promotors and creators of the “post-truth era” (e.g. the will of politicians, propagandists and the authors of conspiracy theories)—truth as it is grasped in the classical theory is in principle non-withdrawable from social discourse, including its philosophical and scientific fields.
