Just Start with Existentialism
Existentialism is the philosophy that refuses to let you off the hook. It starts with a disorienting premise: you are free, radically so, and no god, system, or tradition can tell you what your life is supposed to mean. That freedom sounds liberating until you feel the full weight of it. The existentialists turned that vertigo into some of the most urgent, honest writing philosophy has ever produced.

The Stranger
Albert Camus · 123 pages · 1942 · Easy
Themes: absurdism, alienation, freedom, authenticity
Meursault does not cry at his mother’s funeral. He goes swimming the next day. He shoots a man on a beach. In under 130 pages, Camus creates a character whose emotional detachment forces you to examine everything you take for granted about guilt, morality, and what it means to live honestly.
Why Start Here
“The Stranger” is the ideal entry point for existentialism because it works as a novel first and as philosophy second. You do not need to know anything about Sartre, Heidegger, or phenomenology. You just need to read a short, unsettling story about a man who refuses to play by the rules society expects, and pay attention to how that refusal makes you feel.
Camus called his philosophy absurdism rather than existentialism, and the distinction matters to scholars. But for a reader encountering these ideas for the first time, “The Stranger” lands squarely in existentialist territory: the question of authentic existence, the tension between individual freedom and social expectation, the absence of inherent meaning. It raises all of these without ever becoming a lecture.
The prose style reinforces the philosophy. It is flat, precise, almost cinematic in its detachment. Meursault observes without interpreting. The sun, the sea, the courtroom, the faces of strangers: everything is presented with the same level gaze. That style is the philosophy in action.
What to Expect
A short, intense read that you can finish in an afternoon. Two parts: the first follows Meursault through ordinary days that build toward a sudden act of violence; the second is a courtroom drama that becomes a trial of society itself. The ending demands to be sat with. Many readers immediately want to reread it.
Alternatives
Sarah Bakewell · 440 pages · 2016 · Easy
Sarah Bakewell tells the story of existentialism as a narrative history, following the intersecting lives of Sartre, Beauvoir, Camus, Heidegger, Merleau-Ponty, and others through cafés, love affairs, political upheavals, and bitter intellectual feuds. It reads like a novel about some of the most fascinating people of the twentieth century.
Why Start Here
If you prefer to understand ideas through the people who created them, this is your book. Bakewell does not simplify the philosophy, but she grounds it in concrete human situations. You learn about phenomenology by watching Sartre stare at an apricot cocktail. You grasp Heidegger’s concept of being-in-the-world through his walks in the Black Forest. The ideas become vivid because they are inseparable from the personalities and circumstances that produced them.
The book also provides something the primary texts cannot: context. Existentialism did not emerge in a vacuum. It grew out of two world wars, the occupation of France, the Cold War, decolonization, and the sexual revolution. Bakewell shows how these historical forces shaped the philosophy and how the philosophy, in turn, shaped the world. By the end, you understand not just what the existentialists thought, but why they thought it.
At 440 pages, it is the longest book on this list, but it moves quickly. Bakewell is a gifted writer who knows how to balance ideas and storytelling. It was named one of the New York Times’ Ten Best Books of 2016.
What to Expect
A group biography built around ideas. Each chapter weaves together personal stories and philosophical concepts, moving chronologically from the 1930s to the present day. The tone is warm, witty, and occasionally irreverent. No prior knowledge of philosophy is required. You will come away knowing the major existentialist thinkers, their key ideas, and how they all connected to each other.
Jean-Paul Sartre · 128 pages · 1946 · Easy
In 1945, Jean-Paul Sartre gave a public lecture in Paris defending existentialism against its critics. The result was the clearest, most accessible summary of existentialist philosophy ever written, just over a hundred pages that lay out the core ideas without the technical density of his major works.
Why Start Here
Sartre’s “Being and Nothingness” is over 800 pages of dense phenomenological analysis. “Existentialism Is a Humanism” distills the essential ideas into a text you can read in a single sitting. It was written for a general audience, people who had heard about existentialism and wanted to understand what the fuss was about. That makes it perfect for the same purpose today.
The central argument is built around Sartre’s famous line: “existence precedes essence.” Unlike a paper knife, which is designed with a purpose before it exists, human beings exist first and define themselves through their choices afterward. There is no fixed human nature, no divine plan, no predetermined purpose. You are what you do. That freedom is absolute, and so is the responsibility that comes with it.
Sartre addresses the most common objections to existentialism head-on: that it leads to despair, that it denies morality, that it is purely negative. His responses are clear and often surprising. The lecture format gives the text an energy that his academic philosophy sometimes lacks.
What to Expect
A short, direct philosophical argument written in plain language. Sartre uses concrete examples, a student torn between joining the Resistance and caring for his mother, a waiter performing his role, to illustrate abstract ideas. The Yale University Press edition (translated by Carol Macomber) includes the original lecture plus a transcript of the question-and-answer session that followed, which is fascinating in its own right.
