The criticism of consumer society, propaganda, and the lack of political participation opportunities by Arendt and Luxemburg could not be more relevant today. Both were convinced of the necessity and possibility of fundamental changes, and the foresight in their texts encourages re-reading. Especially in times of crisis, these two critical thinkers offer optimistic insights. Through episodes from the lives of these equally headstrong and intelligent women, Dutch philosopher Joke J. Hermsen compellingly demonstrates that both icons were never swayed from their love for the world. The volume is complemented by impressive original letters from Rosa Luxemburg, which not only address political issues but also engage with literature, music, and nature.
