“Existentialism is a Humanism” is a 1946 lecture by Jean-Paul Sartre that aims to clarify and defend existentialist philosophy against common criticisms. The lecture serves as an accessible introduction to Sartre’s existentialism, focusing on the ideas of freedom, responsibility, and the individual’s role in creating meaning. Sartre addresses concerns that existentialism promotes despair, subjectivity, and moral relativism, arguing instead that it emphasizes human dignity and responsibility.
Sartre begins by explaining the core principle of existentialism: “existence precedes essence.” This phrase encapsulates the belief that humans are not born with a predefined purpose or essence but must define themselves through actions. Unlike objects, which are created with specific functions, humans are “thrown into existence” without any inherent nature or destiny. According to Sartre, individuals must create their essence through choices, accepting full responsibility for who they become. This position contrasts with traditional views that attribute a fixed nature or purpose to humans, either through religious doctrine or deterministic philosophy.
This focus on individual freedom is fundamental to Sartre’s existentialism. He argues that humans are “condemned to be free,” meaning they have no choice but to make choices, whether consciously or passively. Sartre emphasizes that this freedom is accompanied by “anguish,” a feeling that arises when one confronts the weight of responsibility for one’s actions. Every choice a person makes contributes to their identity, and each action implicitly endorses a vision of how humans ought to behave. Sartre calls this phenomenon “universal responsibility,” suggesting that by choosing for oneself, one also sets an example for humanity.
In response to accusations that existentialism leads to moral relativism, Sartre argues that existentialism instead demands a deep sense of ethical responsibility. He rejects the notion of an objective moral code, proposing instead that individuals must act authentically, with awareness of the implications of their actions for themselves and others. This moral stance requires that each person make choices based on their values while acknowledging that these values are chosen, not predetermined. In Sartre’s view, living authentically means acknowledging one’s freedom and the consequences of one’s actions without appealing to external justifications.
Sartre also defends existentialism from charges of pessimism and nihilism. While existentialism confronts the absence of inherent meaning, Sartre argues that it does not promote despair. Rather, it offers an opportunity to find meaning in a self-defined life. He suggests that, instead of relying on external authorities or doctrines, individuals can cultivate meaning through personal commitment and purposeful actions. In Sartre’s philosophy, human dignity arises from the capacity to shape one’s life and embrace freedom, even in a seemingly indifferent universe.
The lecture further addresses critiques of existentialism as overly subjective. Sartre acknowledges that existentialism values individual experience, yet he insists that it does not endorse isolation or self-centeredness. Rather, existentialism emphasizes the interconnectedness of individuals, since every action influences others and reflects values that extend beyond the individual. Sartre argues that this interconnectedness underscores the importance of considering the impact of one’s choices on others, reinforcing the social dimension of existentialist responsibility.
In “Existentialism is a Humanism,” Sartre advocates for a philosophy grounded in freedom, responsibility, and authenticity. He counters objections by emphasizing that existentialism is neither morally indifferent nor nihilistic; instead, it offers a framework for ethical living that respects individual autonomy while acknowledging social obligations. By embracing existentialism, Sartre argues, individuals can live more fully, with a conscious sense of purpose that they create themselves. The lecture remains a defining text for existentialist thought, encapsulating Sartre’s belief in the potential for humans to live meaningfully through self-determined actions and ethical responsibility.
