  Kotarbiński recommended reism as a sound view. In particular, it defends philosophy and ordinary thinking before hypostases, that is, accepting the existence of abstract objects on the basis of using apparent names. Thus, reism defends us against idola fori in Bacon’s sense. Kotarbiński’s reism is perhaps the most radical materialistic nominalism in the history of philosophy. Reism is exceptional to the main tendency in the LWS in that it proposes a uniform language, proper everywhere, including the humanities, sociology and psychology (Kotarbiński supplemented reism by radical realism, that is, the view that there are no mental contents). In this respect, reism resembles physicalism. The troubles of reism are typical those which are in the case of any reductive materialism and nominalism, and concern the interpretation of mathematics, semantics, psychology, the humanities and social sciences.
