Cassier E.Filozofia form symbolicznych. Część pierwsza: Język. Przekład, wstęp i opracowanie Przemysław Parszutowicz, Kęty : Wydawnictwo Marek Derewiecki, 2018
PublicationNeokantysta Cassirer podejmuje wyjściową kantowską intuicję, rozszerza ją jednak także poza przyrodoznawstwo, na cały obszar „rozumienia świata”. […] Sztuka, język, religia i nauka to wymiary ludzkiej aktywności sensotwórczej, które manifestują się jako obszary kultury, każdorazowo różniące się w swej funkcji i ekspresji. Wspólne im jest to, że nie odwzorowują po prostu tego, co dane, lecz że raczej to, co dane, najpierw wytwarzają....

Realizm kapitalistyczny. Czy nie ma alternatywy? / Mark Fisher; przełożył i posłowiem opatrzył Andrzej Karalus
PublicationPraca rozważa, jak neoliberalna hegemonia instalując „ontologię biznesu” we wszystkich sferach rzeczywistości, formatuje niepostrzeżenie nasze pragnienia, aspiracje i nadzieje. Wbrew triumfalistycznej retoryce „efektywności” i „społecznej odpowiedzialności” realizm kapitalistyczny nie przestaje jednak generować systemowych zaburzeń, które w dłuższej perspektywie go destabilizują. Jest nie tylko przyczyną degradacji środowiska naturalnego...
