This special issue of the Journal Labyrinth is dedicated to the philosophy of Jan Patocka. It commemorates not only the 110th anniversary of his birth but also the 40th anniversary of his tragic death in 1977. In that year Patocka became one of the first spokespersons of the civil rights movement Charter 77 - an engagement marked by confrontation with the communist regime, which ultimately cost him his life. The issue's title invokes this double commemoration and alludes to his most famous and most heartily debated book, "Heretical Essays in the Philosophy of History." These essays, written towards the end of his life, in some sense can be seen as the culmination of his inquiries and long-term aspirations in the philosophy of history. Yet, it is by no means unequivocal why the author deemed these six essays to be "heretical."
