Yet, that is exactly what he himself claimed later in life. Was the widespread “decisionistic” reading of The Open Society just a grand misunderstanding, or did Popper change his metaethical views without acknowledging it? I give reasons as to why we should hold the latter to be true. I also argue that even were the former the case, decisionism would still be more compatible with the open society ideal. %B Filozofia %V 75 %P 474 - 489 %G eng %U https://www.sav.sk/journals/uploads/06241548filozofia.2020.75.6.4.pdf %9 State %2 Articles %3 474489
