The paper explores an answer to the following question: what were the „psychological” consequences and operational benefits of affirmative acceptance of Darwin’s theory of evolution by „the Pope of Warsaw positivism?” Świetochowski’s methods of reference towards Darwin’s teachings have been illustrated on the basis of the examples drawn from his journalistic (Liberum veto), scientific (The Sources of Morality), philosophical (The Meditations of a Pessimist), literary (Spirits, Nałęcze), and reminiscent (Memoirs) texts.
