Practical realism is the ethical conception of Tadeusz Kotarbinski, which has met with serious criticism - first of all by Henryk Elzenberg. The author of the article considers some aspects of that criticism correct. He also tries to show how the criticism can be avoided by offering an interpretation of the postulate of practical realism suggested by some earlier texts of Kotarbinski. So understood, the postulate is not seen as the main ideal of life, but as a moral condition which our striving for that ideal should satisfy. The condition requires us to care for others, especially by 'defending them against misfortune'.
