Uwagi krytyczne o Kazimierza Ajdukiewicza semantycznej krytyce idealizmu subiektywnego

The paper contains objections to Kazimierz Ajdukiewicz’s semantic argumentagainst subjective idealism of George Berkeley, formulated in Ajdukiewicz’s articleEpistemology and Semiotics. It is argued that this argument is question-begging,as it presupposes a realistic conception of intentionality. It is analyzed whetherAjdukiewicz’s argument against idealism fromOn the Notion of Existencecould beused to support the former reasoning, and I argue that it could not. I also evaluateRoman Suszko’s modification of Ajdukiewicz argument and show that this modifi-cation is superficial, as it lays on the very same question-begging assumption thatAjdukiewicz made. In the conclusion I attempt a general defense of Ajdukiewicz’sphilosophical method, regardless of its misapplications.
