The series aspires to present a wide and relevant overview of best Polish works in philosophy and philosophical parts of the major fields of the humanities: political and social sciences, history, religious studies or what is named in Poland "the history of ideas". The subsequent editions of books within this series are either re-editions of the works previously published in non-Polish versions, or new translations from Polish. Some books contain extended works, other ones provide collections of smaller papers. Some of the authors presented in the series are widely acknowledged and regarded to be the "classics" of Polish intellectual life in the second half of the 20th Century, others are recognized as outstanding professors today. The quality and fame of the works and authors presented in the series are the only criteria for inclusion. The series is open to all streams of Polish philosophy: from analytical philosophy, through phenomenology and hermeneutics, to existential or religious philosophies. Also the word "philosophy" should be understood very widely in this case.
