Executive Summary
Originally delivered as a public lecture at the Club Maintenant in Paris on October 29, 1945, 'Existentialism Is a Humanism' (1946) serves as Jean-Paul Sartre’s spirited defense of his philosophy. It was written to refute common misconceptions that existentialism was a philosophy of 'quietism' (inaction), pessimism, or an abandonment of moral values. Sartre argues that by stripping away divine mandates and fixed human natures, existentialism actually empowers individuals, placing the full weight of responsibility for the human condition onto human shoulders. The text is celebrated for its accessibility, distilling the dense concepts of his 800-page magnum opus, 'Being and Nothingness', into a concise call to action (Source: Stanford Encyclopedia of Philosophy, LitCharts).
Key Themes
Existence Precedes Essence
The fundamental tenet that humans are not born with a predefined purpose or 'nature' (unlike a manufactured object like a paper-knife). Instead, they first exist and only through their choices and actions do they define what they are (Source: Wikipedia, Internet Encyclopedia of Philosophy).
Radical Freedom and Responsibility
Because there is no God or deterministic 'nature' to provide an excuse, man is 'condemned' to be free. This freedom entails a total responsibility not just for one's own self, but for all of humanity (Source: Philosophy Now).
Anguish, Abandonment, and Despair
These are not negative states to be avoided, but the necessary emotional results of recognizing one’s freedom. 'Anguish' is the realization of one's responsibility as a 'legislator' for mankind; 'Abandonment' is the realization that God does not exist to provide values; and 'Despair' is the realization that we can only rely on what is within our own will and action (Source: LitCharts, Blinkist).
The Interpersonal Nature of Freedom
Sartre argues that one cannot truly seek their own freedom without also seeking the freedom of others, attempting to bridge the gap between individualist philosophy and social ethics (Source: Goodreads Reviews, Stack Exchange).
