"Vergänglichkeit" by Sigmund Freud is a philosophical essay written in November 1915. Framed as a dialogue between Freud and poet Rainer Maria Rilke, the essay explores their contrasting views on transience during a summer walk. While Rilke finds life's fleeting nature disheartening, Freud argues it creates value and beauty. Written amid World War I, the work reflects on impermanence as a fundamental aspect of human existence, blending personal reflection with philosophical meditation.
