If you were asked to picture a typical existentialist, you might think of an angsty person situated in a Parisian cafe, adorned with a black turtleneck, drinking cocktails, miserably smoking cigarettes — a person who laments about the meaninglessness of life, and despairs that we must somehow forge a living for ourselves in strange societies into which none of us even asked to be born.

And, in many ways, this picture — based on the crude popular culture conception of existentialism — is entirely accurate. The Parisian cafe scene of the 1930s-50s was the hub for such famous existentialist figures as Jean-Paul Sartre, Simone de Beauvoir, Maurice Merleau-Ponty, and Albert Camus — all of whom discussed the meaninglessness of life and most definitely did fuel themselves with cocktails and cigarettes.

But beyond this fond caricature of the lifestyles and demeanours of existentialists, the philosophy of existentialism of course goes much deeper. For many, it's a fascinating way of thinking about the world, as well as our place in it.

So what is existentialism, exactly? Well, in a nutshell, existentialism concerns itself with finding ways to explain the individual human experience, focusing like a laser on what it means to exist as an individual human being in a universe we don’t understand.

Defining it further than this requires some clarification, for existentialism is a term not limited to philosophers, but also used to describe the work of novelists, playwrights, and artists — notably Fyodor Dostoevsky, Franz Kafka, and Samuel Beckett — making existentialism as much a general cultural movement as it is a specific philosophy.

Let's take a quick look at the cultural movement, before diving into the three key principles of formal existentialist philosophy.

Existentialism as a cultural movement

The broader cultural use of the term ‘existentialist’ typically describes any thinker who places an emphasis on individual lived experience — particularly on the tension between the fact we are ultimately responsible for our choices, yet lack a clear framework for knowing if the decisions we make are the right ones, or if they even matter at all.

This tension is generally accompanied by the suspicion that, beyond the everyday, there lies a deeper human need that natural science and traditional religions have not been able to fulfill. As such, existentialist works commonly feature themes like dread, boredom, anxiety, alienation, the absurd, freedom, commitment, nothingness, and what it really means to be an embodied being in an apparently uncaring, unknowable universe.

In this regard, Dostoevsky’s Notes from the Underground and Kafka’s The Trial are classic examples of existentialist novels, and the plays of Samuel Beckett and sculptures of Alberto Giacometti explore existentialist themes in fascinating, disturbing ways.

Existentialism as a philosophy

The more formal philosophical side of existentialism, meanwhile, grapples with its core themes and concepts more directly, and it’s worth taking a brief look at its history, which can be confusing.

For instance, the 19th-century Dane Søren Kierkegaard is commonly regarded as the first existentialist philosopher, though he himself never used the term — and probably would have dismissed the label, had he been alive to do so. In fact, 20th-century philosophers Martin Heidegger and Albert Camus did dismiss the label during their lifetimes, despite being considered core to existentialist thought.

‘Existentialism’ was explicitly adopted by the French philosopher Jean-Paul Sartre, who came to define the subject around his own works. Only then were earlier thinkers like Kierkegaard and Friedrich Nietzsche retrospectively recognized as precursors to the movement — with a number of Sartre’s contemporaries also lumped in under the term, regardless of whether they explicitly identified as such.

Given the confused allocation of who is and who is not an existentialist, some argue that only the work of Jean-Paul Sartre should be labelled pure existentialism, seeing as he was the most explicit in defining the term. It’s true that Sartre perhaps provided the main thrust of existentialism as a movement, but as we shall see his work was deeply influenced and informed by his precursors and contemporaries.

Of this work, there are generally three core principles that emerge as central to existentialist philosophy: phenomenology, freedom, and authenticity. Let’s take a quick look at each in turn.

1. Phenomenology

Phenomenology is a philosophical movement developed by Edmund Husserl in the early 20th century and later adapted by Heidegger and others. Phenomenologists are interested in examining the underlying structures of consciousness and experience, typically emphasizing the crucial importance of the first-person perspective in understanding ourselves and the world around us.

For example, if we were to describe our experience of, say, looking at a bowl of fruit, typically we would rather passively describe the distinct objects we see: a banana, an apple, some oranges, the bowl itself.

But phenomenologists would encourage us to take a step back here. What do we actually experience when looking at the bowl of fruit? Is it just these distinct objects? Or is it rather a unified multitude of shapes, textures, colors, sounds, smells, the passing of time, our mood, perhaps a brief desire for an orange, the overpowering repulsion of a fruit we don’t like?

The point is that, when you think about it, our experience of the world is characterized wholly by intentionality.

Though we may typically describe our experiences as though we are mere subjects passively perceiving objects, we do not actually experience the world in this way. Rather we are immersed in whatever we are experiencing, existing in the world through an ever-shifting kaleidoscopic lens of memory, desire, mood, attention, inattention, intention.

So, when looking at the bowl of fruit we see not mere passive objects but a potential snack — or even a potential allergic reaction. We cast our own selves into the world and they stick to every object of our experience: our perceptions are our concepts and intentions mirrored back at us. Thus we see not just a piece of wood attached to some metal but a hammer, a tool — something we can intentionally use.

This intentional, first-person perspective — the way we actually experience life — is all too often stripped from our descriptions of the world, phenomenologists argue, when it is precisely in examining this moment-to-moment, direct kind of experience that rich philosophical insight is to be found.

For our first-person intentionality is not just a property of our minds, Husserl argues: it is the framework through which the world and our minds become intelligible. Removing it from our considerations (as we attempt to do in science to create a third-person ‘objective’ perspective) leaves an unintelligible picture of human experience, and causes strange philosophical problems between mind and body that led to centuries of confusion arising from Descartes’s skepticism and cogito ergo sum.

So, reclaiming the first-person perspective in all its immediacy and complexity — and acknowledging how entangled this perspective is with the world we perceive — lies at the heart of phenomenology, and became a useful way of thinking about the world for existentialists like Sartre. As philosophy professor Steven Crowell writes in his summary of existentialist thought:

The phenomenological approach gave philosophical shape to the basic existential insight that thinking about human existence requires new categories not found in the conceptual repertoire of ancient or modern thought; human beings can be understood neither as substances with fixed properties, nor as subjects interacting with a world of objects.

2. Freedom

If the principle of phenomenology gave existentialism its basic shape — i.e. a technique for getting at how things really are, for going behind the stale categorizations of common sense and natural science to describe human existence for what it really is — then the principle of freedom gave existentialism its founding value. As contemporary philosopher Jonathan Webber argues in his 2018 work, Rethinking Existentialism:

As originally defined by Simone de Beauvoir and Jean-Paul Sartre, existentialism is the ethical theory that we ought to treat the freedom at the core of human existence as intrinsically valuable and the foundation of all other values.

As many existentialist thinkers were atheists, they believed no pre-ordained paths or objectives are assigned to any of us, and that human beings do not possess any inherent ‘nature’ or ‘value’ more fundamental than the fact we exist. In other words, being conscious of our own existences is the most fundamental thing about what it means to be a human being.

Sartre sloganizes this thought with his famous saying, existence precedes essence, and concludes that it is thus up to us, moment to moment, to use our existences to shape our own natures and values, to create whatever ‘essence’ — whatever human being — we choose to become.

The upshot of this is that, on the existentialist view, we bear total responsibility for who we are, and the decisions we make are ours (of course, many neuroscientists and philosophers today disagree that we have such freedom, arguing that free will is an illusion).

But for the existentialists, in a universe apparently devoid of direction, purpose, or meaning, this dizzying freedom is the source of much of our anxiety — leading Sartre to assert that we are in fact ‘condemned’ to be free.

Kierkegaard summarizes this thought — that our existential freedom leads to anxiety about the limitless possibilities available to us — in his 1844 work, The Concept of Anxiety:

Anxiety may be compared with dizziness. He whose eye happens to look down the yawning abyss becomes dizzy. But what is the reason for this? It is just as much in his own eye as in the abyss, for suppose he had not looked down. Hence, anxiety is the dizziness of freedom, which emerges when the spirit wants to posit the synthesis and freedom looks down into its own possibility, laying hold of finiteness to support itself.

3. Authenticity

Finally, once we’ve acknowledged the importance of the first-person perspective, and recognized the ultimate freedom we have in our lived existence moment-to-moment, we come to another core principle of existentialist philosophy: adopting a stance of authenticity.

To overcome the anxiety and alienation that a recognition of our ultimate freedom and responsibility can cause in us, we should face up to who we are — including the fact that we are mortals who will one day die, as other philosophies like Epicureanism advise — and be true to it, refusing to bow down to anything that compromises our personal freedom or authenticity, be it external pressures, societal norms, or escapist pleasures.

As Webber puts it, the existentialism of Sartre and de Beauvoir begins with “eudaimonist arguments for the virtue of authenticity” and finally affirms “a categorical moral imperative of authenticity”.

Yale professor Noreen Khawaja, meanwhile, in her work The Religion of Existence confirms that “the idea of personal authenticity [is] at the center of existential thought.”

Where does existentialism leave us?

In summary, then, while the popular conception of existentialism rather narrowly revolves around dread and angst in a meaningless universe, the formal philosophical movement is more holistic, and generally involves three core principles.

Firstly, it involves a recognition of the foundational importance of the phenomenological, intentional first-person perspective in properly understanding ourselves and the world. Secondly, it refers to an acknowledgement of the freedom and responsibility we have in our lived experience. And finally, it defends the idea that personal authenticity is our chief virtue, for it allows us to face up to who we are, live in harmony with the world, and thereby reduce our feelings of anxiety and alienation.

This rather spiritual struggle takes place against the backdrop of an uncaring, Godless universe — one that we have been ‘thrown’ into and left to deal with ourselves — meaning that though many existentialists were atheists, their writing, as Khawaja puts it, “feels religious to its readers.”
