The paper deals with one of the most difficult and worrying philosophical problems, that is the problemate of the truth and the lie. First, certain analyses are made with reference to notions related to attempts at answering the questions: What is the truth? And What is the lie?, then – taking into account problems pertaining to political and social ethics – various notions of the truth and of the lie are juxtaposed, respectively, in such a way as to be able to answer the basic question raised in this work: Does the lie contradict the truth? Answers to this question are not unambiguous. In the author’s opinion, this presents a peculiar challenge to philosophy, and – in particular – to philosophy of politics, as well as to the idea of shaping the culture of politics and logic in our society.
