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.
