The aim of this paper is to invite the reader to reflect on the essence of truth and post-truth in two approaches present in humanities and social sciences: trans-humanism and post-humanism. The notions of truth and post-truth, just like those of trans- and post-humanism, do not have a single defining interpretation. This implies disputes about what truth is and what is the role of man as an being, capable of creative activity, and thus of creating other entities and concepts describing them. However, the problem still remains the doubt as to what extent the ability of creative action allows man to know the truth (alternatively, to establish it), and to what extent it leads us astray. Post-truth emerges as a proposition in the face of the impossibility of reaching a consensus on the former. It is similar in the case of trans- and post-humanism, as concepts offering improved, because more up-to-date, approaches to the exploration of the human being himself, the motives of his actions, and his progress. The issues are presented by means of a critical analysis of selected scientific discourses, including definitions and research approaches that are gaining popularity in academia of the so-called Western cultural circle.
