Jan Blonski, Professor of Polish Literature at the Jagiellonian University has discussed this paradox of antisemite and heroic rescuer in depth both in his seminal essay on Poles and the Holocaust "Poor Poles look at the Ghetto" (the title refers to a famous poem by Milosz written in 1943, the essay is mainly concerned with indifference and failure to act) and in a shorter essay "Pole-Catholic, Catholic-Pole", devoted to Kossak specifically. (For the former see 'My Brother's Keeper? Recent Polish debates on the Holocaust New York 1990, originally Tygodnik Powszechny 1987. Also Les Temps Modernes #516 (1989), the latter in Jews and Christians in a Pluralistic World London, 1991.)
