Jean-Paul Sartre, a towering figure in 20th-century French philosophy, articulated a profound insight into the human condition that underpins his existentialist thought. This idea, central to his 1946 lecture "Existentialism is a Humanism," emerged from a world grappling with the aftermath of devastating conflicts, particularly World War II and the Nazi occupation. [cite: 9, 16] During this tumultuous period, which deeply impacted Sartre personally, individuals were forced to confront stark choices of integrity, betrayal, and survival, leading him to assert that human existence precedes any predefined essence. [cite: 4, 8, 14]

For Sartre, to say that humans are "condemned to be free" means that we are "thrown" into existence without any inherent purpose or nature. Unlike objects, humans are not created with a blueprint; instead, we must define ourselves through our actions and choices. [cite: 2, 8
