Warum Krieg?
DE · German
The famous 1932 letter exchange between Einstein and Freud, read in full in the original German: Einstein asks whether humanity can free itself from the curse of war — Freud answers with the picture of an innate drive toward aggression and destruction that culture and law can only partly tame. Both letters are read in voices modeled on the original archival recordings of Einstein and Freud: you hear the correspondence as if the two men were speaking. A short introduction and chapter titles in a narrator's voice frame the exchange. For anyone ready to finally hear the exchange between the century's greatest physicist and its most influential psychologist — on the one question they could not answer. Long after the last letter, one feeling remains: the question is still open — and you have heard it asked.

Zum ewigen Frieden
DE · German
Kant's peace treatise of 1795, read in full in the original German: the six Preliminary Articles that end the state of war, the three Definitive Articles that found a lasting peace — republican constitutions, a federation of free states, a cosmopolitan right to hospitality — and the two Appendices in which Kant demands that politics finally answer to morality. A short introduction frames the treatise; after each chapter a brief summary collects the main ideas. For anyone ready to finally hear the little book that invented the idea the United Nations is built on — the question of war and peace, answered 230 years ago. Long after the last chapter, one feeling remains: peace is not given, it is made — and you have heard the case made.

Relativitätstheorie · Geometrie und Erfahrung
DE · German
Einstein's two popular classics, read in full in the original German: his own walkthrough of the special and the general theory of relativity — no formulas, no prior training, just attention — followed by 'Geometrie und Erfahrung', his 1921 Berlin lecture in expanded form, on the question of how pure mathematics manages to describe the actual world. Read in a synthetic voice modeled on Einstein's original archival recordings, so the explanation sounds like the man himself. For anyone ready to finally hear Einstein teach his own theory, in the language he wrote it in. Long after the last chapter, one feeling remains: space and time are not what you grew up believing — and you heard Einstein himself explain why.

Jenseits von Gut und Böse
DE · German
Nietzsche's mature masterwork, read in full in the original German: a spoken introduction, the Vorrede and all nine Hauptstücke — from the prejudices of the philosophers through the free spirit, religion, morality, the scholars and the virtues to the question of what is noble. For anyone ready to finally hear the book behind the label 'beyond good and evil'. Long after the last chapter, one feeling remains: you have seen through the old values — and heard what might stand beyond them.
