In the article, the author analyses the impact of the tragic experiences during the Holocaust on contemporary ethics and literature. Such considerations coincide with yet another anniversary – the liberation of the Auschwitz concentration camp, celebrated globally as Holocaust Memorial Day. The article also considers the reasons why testimonies from Holocaust survivors have not had an adequate impact on society. The author argues that trivialisation of the Holocaust tragedy occurred in modern science and it is related to the fact that traditional ethics has not been able to convincingly explain why the Holocaust occurred in the most civilised nations. Thus, Holocaust testimonies should be constantly popularised in society for the good of all mankind. Literature seems to be the best form of mass media for this task and it is also a recorder of human emotions. According to the author, it is essential that humanity is protected this way against the possibility of a similar tragedy occurring in the future.
