The aim of this article is to analyze Aleksander Swietochowski's essay 'Dumania pesymisty' (Thoughts of a Pessimist) on the background of literary and philosophical texts by Dostoevsky, Nietzsche, Mill, Hobbes, Feuerbach, Stirner and Sartre. The author considerations focus on questions - What are ethical consequences of life without illusions? Is awareness of such a state equal with being committed to egoistic behaviour? Does egoism eliminate any possibility of rational reconstruction of public life, understood as a positivistic ideal?
