The notion that humans are bound to their freedom comes from Jean-Paul Sartre, a prominent 20th-century French philosopher and a leading figure in existentialism. He articulated this idea particularly in his philosophical works like "Being and Nothingness" and his lecture "Existentialism is a Humanism." Sartre's core premise, "existence precedes essence," posits that unlike objects created with a predetermined purpose, humans are born without an inherent nature or divine blueprint. We are simply "thrown into the world" and, in the absence of a God or pre-set values, are entirely free to define ourselves through our choices and actions.

This radical freedom, however, is not presented as a comforting gift but as a profound burden, hence the term "condemned." Because there are no external rules or guides to dictate our behavior, every decision we make is solely our own responsibility. This absolute accountability for shaping our own identity and values creates a deep sense of anguish, as we are forced to confront the weight of our choices without any excuses or pre-existing moral framework to fall back on. Even the act of choosing not to choose is, in itself, a choice for which we are responsible.

Sartre's philosophy encourages individuals to embrace this responsibility rather than falling into "bad faith," which is the self-deception of attributing one's choices or circumstances to external factors. This resonates in real-world situations, from personal career paths and relationships to broader moral dilemmas, where individuals must actively decide and own the consequences, rather than passively accepting a perceived destiny. Historically, this emphasis on individual agency gained significant traction in post-World War II Europe, offering a framework for meaning and action in a world that had seemingly lost its traditional certainties. It is a powerful call to authenticity, urging us to recognize that we are the sole architects of our lives and, by extension, contribute to defining what it means to be human.
