Existentialism is perhaps the most enduring “mood” in the history of Western thought. To the casual observer, it is synonymous with mid-century Parisian cafes, black turtlenecks, and a certain grim obsession with the pointlessness of life. However, beneath the cinematic aesthetic lies a rigorous, demanding, and ultimately transformative framework for understanding human agency.

At its core, existentialism is the study of the individual’s struggle to find meaning in a universe that appears to offer none. It is a philosophy of action, a rejection of pre-determined “systems,” and a radical call to personal responsibility.

The Origins: Gabriel Marcel and the Naming of a Movement

To understand the definition of existentialism, one must first look at its naming—a process that was itself a point of philosophical contention. While Jean-Paul Sartre is the name most frequently associated with the movement, he did not coin the term. That credit belongs to Gabriel Marcel, a Catholic philosopher and dramatist.

In 1943, Marcel used the term existentialisme to categorize the growing school of thought shared by Sartre and Simone de Beauvoir. Ironically, Sartre initially found the label reductive and rejected it. It was not until his landmark 1945 lecture, Existentialism is a Humanism, that Sartre adopted the term as a badge of honor to defend his ideas against public misconception.

This historical nuance is vital. It reminds us that existentialism was never a monolithic “club.” It was a heated, decades-long conversation between:

• Theistic Existentialists: Such as Marcel and Søren Kierkegaard, who argued that while we are free, our freedom finds its ultimate fulfillment in a relationship with the Divine.
• Atheistic Existentialists: Such as Sartre and Beauvoir, who argued that because there is no God, humans are “abandoned” to create their own values from scratch.

The Core Tenet: Existence Precedes Essence

The foundational pillar of existentialist thought is Sartre’s dictum: “Existence precedes essence.”

To appreciate the gravity of this statement, consider almost any object in our world—a paperknife, a clock, or a software program. For these objects, the “essence” (the purpose, blueprint, or definition) comes before the physical object ever exists. A craftsman has a concept of what the tool is before he builds it. Its purpose is fixed; it can never be anything other than what it was designed to be.

Existentialists argue that human beings are the sole exception to this rule. We are “thrown” into the world without a blueprint. We appear on the scene, we exist, and only then do we define what we are through our actions. There is no “human nature” to hide behind, no biological destiny that dictates our character, and no divine script. As Sartre put it, “Man is nothing else but that which he makes of himself.”

The Rebellion: Why Existentialism is an “Anti-System”

Throughout the 18th and 19th centuries, philosophy was dominated by “System-Builders.” Thinkers like Georg Wilhelm Friedrich Hegel attempted to create grand, logical architectures that could explain the entirety of history, logic, and the human spirit. In these systems, the individual was often treated as a mere component—a cog in the machinery of “Universal Reason.”

Existentialism was born as a violent rebellion against these structures. Søren Kierkegaard, the 19th-century Dane often called the father of the movement, argued that systems are for abstract concepts, not living people.

The Critique of Abstraction

Kierkegaard pointed out a fundamental flaw in systematic philosophy: it can explain the mechanics of a heart, but it cannot explain the experience of a heartbreak. A system is static and dead; an existing individual is in a constant state of “becoming.” By the time a philosopher has built a system to describe life, life has already moved on.

Is “Anti-System” Still a System?

Critics often argue that by creating a vocabulary of “Authenticity,” “Bad Faith,” and “The Absurd,” existentialists simply built a new system in a different guise.

• The Argument for “System”: If Sartre says we are “condemned to be free,” is that not a universal law? If Authenticity is the goal, is that not a new morality?
• The Existentialist Rebuttal: The existentialist would argue that their philosophy is a method, not a system. A system provides answers (The “What”); a method provides tools (The “How”). Existentialism refuses to give the reader a map, insisting instead that they learn to navigate by their own internal compass.

The Burden of Freedom: Anguish and Abandonment

If existence precedes essence, then we are entirely responsible for our own definitions. This freedom is not a gift in the traditional sense; Sartre famously noted that we are “condemned to be free.” This “condemnation” stems from the fact that we did not choose to be born, yet once we are here, we are responsible for everything we do. This realization triggers three distinct psychological states:

1. Anguish: This is the anxiety of realizing that our choices have weight. When I choose a path, I am not just choosing for myself; I am creating an image of what I believe a human being ought to be.
2. Forlornness (Abandonment): This is the feeling of being alone in a universe without an external moral authority. If there is no “God’s-eye view” to validate our choices, we must realize that we are the sole source of value.
3. Despair: This is the recognition that we can only rely on our own will and the probabilities that make our actions possible. We cannot control the external world; we can only control our commitment to our own projects.

Authenticity vs. Bad Faith (Mauvaise Foi)

If there is no objective meaning handed down from above, how should one live? The existentialist answer is Authenticity. To live authentically is to acknowledge one’s total freedom and take full ownership of the consequences.

The opposite of authenticity is “Bad Faith.” This is the act of lying to ourselves to escape the “anguish” of freedom. We fall into Bad Faith whenever we say:

• “I had no choice.”
• “That’s just the way I am.”
• “I’m just following orders.”

Facticity and Transcendence

To avoid Bad Faith, one must balance Facticity and Transcendence.

• Facticity refers to the brute facts of your life: your place of birth, your body, your past.
• Transcendence is your ability to project yourself beyond those facts.

Bad Faith occurs when we lean too far into either. If you say, “I am just a waiter” as if it were a biological fact like your eye color, you are denying your transcendence. If you say, “I can fly” while ignoring gravity, you are denying your facticity. Authenticity is the thin line where you acknowledge the facts of your life while asserting your freedom to choose how you relate to them.

The Absurd: Camus and Sisyphus

While Sartre focused on freedom, Albert Camus explored The Absurd. The Absurd is not simply that life is meaningless; it is the “divorce” between the human mind’s desperate longing for order and the “unreasonable silence” of the universe.

Camus famously used the Myth of Sisyphus to illustrate this. Sisyphus, condemned to roll a boulder up a hill for eternity only for it to roll back down, is the ultimate “absurd hero.” Camus argues that “the struggle itself toward the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.” By accepting the futility of the task and continuing anyway, Sisyphus triumphs over his fate.

Critiques: Marxism and Structuralism

No exploration of existentialism is complete without addressing those who sought to dismantle it.

The Marxist Critique

Marxists argued that Sartre’s “absolute freedom” was a luxury of the middle class. If a person is starving or working 16 hours a day in a factory, are they truly “free” to choose their essence? They argued that economic systems dictate our lives far more than individual choices do. Sartre eventually spent much of his later life trying to reconcile existentialism with Marxism, acknowledging that “need” can limit freedom.

The Structuralist Critique

In the 1960s, Structuralists like Claude Lévi-Strauss and Michel Foucault argued that we are “spoken by” our culture, language, and biology. They suggested that the “Individual” is an illusion and that we are actually just intersections of various unconscious systems. To them, the existentialist focus on “choice” was naive.

---

Conclusion: The Sovereign Individual

Despite these critiques, existentialism remains a vital philosophical force because it addresses the “inner life” that structuralism and sociology often overlook. It provides a framework for those moments when an individual stands at a crossroads and realizes that no system or external authority can make the final choice for them.

Ultimately, existentialism suggests that meaning is not something to be discovered, but something to be forged. It proposes a philosophy of sovereignty rather than despair. By stripping away the comfort of “destiny” or “divine plan,” the movement leaves the individual with a challenging but potentially liberating premise: we are the sum of our actions.

In the existentialist view, the universe may remain silent and the boulder may eventually roll back down the hill. However, as long as a person exists, the philosophy maintains that the “brush” remains in their hand. The canvas—however limited by the brute facts of history and biology—is still theirs to paint.

In the modern attempt to map the human mind, there is a figure who stands at the crossroads of every major theory, holding a “Stop” sign. Raymond Tallis—a retired Professor of Geriatric Medicine and a neuroscientist—is a man who knows the literal “meat” of the human brain as well as any surgeon. Yet, he has become the most formidable critic of the idea that the brain is the mind.

Tallis is a “Professional Dissenter.” He is an atheist who rejects the “Ghost in the Machine” (Substance Dualism) because he finds no evidence for a separate soul. However, he also rejects the “Machine” (Materialism) because he finds it logically hollow. He argues that we are currently suffering from a collective intellectual ailment he calls Neuromania: the mistaken belief that by looking at brain activity, we are looking at the human person.

The War on Neuromania and Darwinitis

Tallis’s project begins with a stinging critique of the two pillars of modern secular thought. He believes that in our rush to be “scientific,” we have actually lost sight of what it is like to be a person.

1. The Coordinate Gap

The cornerstone of Tallis’s critique is what he calls the Coordinate Gap. When a neuroscientist uses an fMRI to watch a brain, they see neural firing at specific spatial coordinates (x, y, z). These are “public” facts. However, when you experience the smell of a rose or a memory of your first day of school, that experience has no location in space. There is no “redness” in the neurons, and there is no “smell” in the synapses.

Tallis argues that even if we had a “Super-Neuroscience” that could track every atom, we would still be describing the Object while ignoring the Subject. To say that a surge of dopamine is the feeling of love is a category error. One is a physical process; the other is a meaningful state. By ignoring this gap, Neuromania treats the “user” as if they are just another part of the “hardware.”

2. The Fallacy of Darwinitis

The second pillar of Tallis’s critique is Darwinitis—the tendency to explain every human behavior purely through the lens of evolutionary survival. While Tallis accepts Darwinian biology for the body, he argues that humans have “stepped out” of the biological stream. We are the only animals that lead “lives” rather than just moving through “biological sequences.”

For a materialist like Daniel Dennett, our behaviors are “sub-routines” for survival. But Tallis points out that humans do things that have no biological utility: we write poetry, we study ancient history, and we debate the nature of consciousness itself. To explain a political revolution or a symphony purely as a survival tactic for “selfish genes” is to ignore the vast, non-biological space humans inhabit. Tallis argues that we are Agents, not just organisms.

The Failure of the “Meat Computer” Metaphor

One of Tallis’s most persistent targets is the casual use of computer jargon to describe human biology. This “computational theory of mind” finds its most famous champion in Daniel Dennett, who views the human brain as a biological machine running “user-illusions.” We have become accustomed to saying that the brain “processes data,” “encrypts memories,” or “runs programs.” Tallis argues that this is not just a metaphor; it is a profound misunderstanding of both computers and humans.

A computer does not “know” it is calculating a square root; it is simply a series of physical switches governed by the laws of electromagnetism. It only becomes “information” when a conscious human observer interprets the output. By calling the brain a “meat computer,” materialists like Dennett are smuggling a “miniature human” (an interpreter) into the biology without explaining where that interpreter came from. For Tallis, the difference between a pulse of electricity in a silicon wire and the intentional thought about that pulse is an unbridgeable chasm. He insists that a machine has “outputs,” but only a human has “meanings.” This refusal to conflate calculation with consciousness is what sets Tallis apart from Dennett and the “Silicon Valley” school of philosophy.

The Critique of the “Information” Metaphor

In our investigation of Integrated Information Theory (IIT), we looked at the idea that consciousness is a mathematical result of data integration. Tallis is deeply skeptical of this “Informational Turn.” He argues that “Information” is a metaphor we have borrowed from technology and mistakenly applied to nature.

Nature, on its own, does not contain “data”; it contains events. Information is something that happens to a mind, not the “stuff” the mind is made of. This puts him at odds with the “It from Bit” school of thought, as he believes it confuses the mathematical map for the actual territory of felt experience.

The Philosophy of the Hand and the “Thatosphere”

If the mind isn’t a “soul” and it isn’t just “brain-states,” where does it exist? Tallis’s positive position—Humanist Naturalism—suggests that consciousness is a networked phenomenon. He believes humans evolved through a process of Explicitness.

Most animals live in a state of “sentience” (reacting to stimuli). Humans live in a state of “explicitness” (knowing that we are reacting). Tallis traces this back to a physical act: The Pointing Finger.

When the first human pointed at an object, they did something revolutionary. They created a “distance” between the Subject (“I”) and the Object (“That”). This physical distance eventually became a mental distance, allowing us to think about things rather than just reacting to them. This led to the creation of the Thatosphere—a shared, virtual world of meanings, facts, and history that exists between people.

The “Mind” is not in the neurons; it is in the shared world we build through language and culture. We inhabit a “community of minds” that has been under construction for thousands of years. Tallis argues that we belong to a “we” that cannot be reduced to an “it.”

The Rejection of Panpsychism and Process Philosophy

Because Tallis is committed to a rigorous, objective science, he finds the recent move toward Panpsychism (the idea that atoms are conscious) to be a “lazy verbal maneuver.” He is equally critical of Process Philosophy, such as the “Actual Occasions” of Alfred North Whitehead.

Tallis argues that Whitehead is guilty of the “Fallacy of Misplaced Sentience.” By redefining the building blocks of the universe as “throbs of experience” or “prehensions,” Process Philosophy attempts to solve the mind-body problem by projecting human qualities onto physics. To Tallis, an electron does not have a “primitive feeling” or an “aim”; it has a trajectory governed by physical laws. He believes these theories actually devalue the human mind by “thinning out” what it means to have an experience, spreading it so thin across the universe that the word “consciousness” loses all specific meaning.

Similarly, he parts ways with George Berkeley’s Idealism. While Berkeley argues that the world is a “Great Thought” in the mind of God, Tallis remains a staunch naturalist. He believes the physical world is real and existed long before we did. His “heresy” is simply the claim that the physical language we currently use (the language of mass, charge, and neurons) is the wrong language for describing the mental reality of being a subject.

Principled Ignorance

The most frequent critique of Tallis is that he doesn’t have a “final answer” to replace the theories he dismantles. He calls his stance Principled Ignorance. He argues that we are currently “Pre-Copernican” regarding the mind. Just as ancient people thought the Sun moved because it felt that way, we currently think the mind is “produced” by the brain because that’s where the “hardware” is located. Tallis refuses to settle for a “cheap” answer like Swinburne’s “Ghost” or Dennett’s “Illusion.” He believes that admitting we don’t know is more professional—and more scientific—than pretending that an fMRI scan is the same thing as a first-person experience.

Conclusion: The Gap in the Map

Raymond Tallis’s work serves as a necessary check on the “explanatory exuberance” of modern science. While he does not offer a supernatural alternative, he insists that a complete map of the brain is not the same as a complete map of the human person.

By identifying the Coordinate Gap and the Thatosphere, Tallis suggests that the “mind” might not be a thing we can find inside a skull, but a relational state that exists between people, language, and history. He leaves us with a version of Naturalism that is far more complex and open-ended than a simple machine. He doesn’t make the mind a miracle, but he makes the “Machine” of the world far more extraordinary than we have been led to believe.

Tallis doesn’t ask us to believe in the supernatural; he simply asks us to recognize that the “I” remains an outlier—a subject that refuses to be reduced to a collection of objects. In the end, his philosophy is a defense of the human agent: the creature that points at the stars and, in doing so, steps out of the dark, silent world of “dead matter” and into the light of shared meaning.

Galen Strawson	A fundamental property of all matter (Panpsychism).	A “verbal maneuver” that fails to explain the unique nature of human agency.
George Berkeley	The universe is fundamentally mental (Idealism).	Too extreme; we must respect the independent reality of the physical world.
Integrated Information	A mathematical result of complex data integration (Phi)	Confuses “information” (a human concept) with “causation” (a physical fact).
Raymond Tallis	An “Explicit” state of agency in a shared “Thatosphere.”	We are “Naturalized Subjects” who cannot be found on a brain map.

To the contemporary reader, skepticism is an intellectual defensive posture. It is the “baloney detection kit” of the scientist or the investigative journalist. However, the history of Western thought reveals that skepticism began not as a way to find facts, but as a specific methodology for achieving psychological neutrality. The transition from the ancient Skeptikos to the modern Skeptic represents a fundamental shift in the perceived purpose of human reason.

I. The Ancient Horizon: The Gift of Ataraxia

In the Hellenistic period, skepticism was a therapeutic art. As the philosopher Pierre Hadot explores in What is Ancient Philosophy?, the skeptic was not seeking to “debunk” external claims, but to transform an internal quality of life. The ancient practitioner did not view the inability to know the “truth” as a failure of the mind, but rather as the beginning of a life free from the agitation of dogmatism.

The Mechanism of Isostheneia

The ancient Pyrrhonist practiced the art of isostheneia—the ability to find an equal and opposite argument for every claim. This was not a dismissal of facts, but a rigorous intellectual training. When one school of thought argued that the universe was governed by a divine plan, and another argued for random atoms, the skeptic would observe that both positions carried significant weight.

By meticulously balancing the evidence, the skeptic reached a point where the mind could no longer lean toward one side or the other. This stalemate was the intended goal. Once the mind finds that arguments are balanced, it naturally enters a state of Epoche, or the suspension of judgment. In this silence, the ancient skeptic found Ataraxia, or “untroubledness.” While others spent their lives in the heated pursuit of absolute truth, the skeptic was able to live simply according to appearances and custom, unburdened by the psychological weight of needing to “know” for certain.

The Ten Tropes: A Toolbox for Neutrality

To help students achieve this state, the ancient skeptics utilized a list of arguments known as the Ten Tropes of Aenesidemus. These were not used to prove others wrong, but to remind the practitioner of the relativity of perception.

• Differences in Animals: A rose appears differently to a bee than it does to a human. Both perceptions are valid within their own biological context, yet they differ, suggesting that the “true” nature of the rose remains hidden.
• Differences in People: One individual finds a room cold; another finds it warm. There is no “correct” temperature independent of the observer.
• Circumstances: The world looks different when a person is in a state of joy versus a state of grief, or when awake versus when dreaming.
• Positions and Intervals: An object looks different from a distance than it does up close; a mountain looks like a smooth cone from afar but is jagged and broken when standing upon it.

By running every claim through these tropes, the ancient skeptic found that they could gracefully step away from the conflict of “The Truth.” For them, skepticism was a place of rest.

II. The Social Context of the Ancient Skeptic

To understand the ancient aim, it is necessary to look at the environment in which it flourished. The Hellenistic world was filled with “Dogmatic” schools—Stoics, Epicureans, and Platonists—each claiming to have the final answer to the nature of reality. These claims often led to intense social and intellectual friction. The skeptic functioned as a neutral party within this landscape. By refusing to commit to any single school of thought, the skeptic avoided the social conflicts that arose from being “right.” This allowed for a life of relative ease. They followed the laws of the city, participated in religious festivals, and maintained professional lives, but they did so with an internal detachment. They did not believe the laws were “True” in an ultimate sense; they simply followed them because it was the most peaceful path through a complex world.

III. The Cartesian Transition: Establishing the Foundation

The shift away from this tranquility began in the 17th century with René Descartes. This era marked a move toward using doubt as a temporary “solvent” to find a foundation that could never be dissolved. It was the moment skepticism moved from being a destination to being a grueling passage.

Doubt as a Pre-Condition for Certainty

Descartes’ “Methodological Doubt” was a rigorous intellectual exercise that required immense mental stamina. He famously doubted his own senses, the existence of his body, and the reality of the physical world. Unlike the ancient skeptic who found comfort in the “grey areas” of these uncertainties, Descartes viewed doubt as an obstacle to be overcome—a dark night of the soul that had to be endured to reach the light of certainty.

The Theological Context

In his Meditations on First Philosophy, Descartes sought to use this newfound certainty to provide a logical “rock” for the existence of God and the soul. After reaching his famous conclusion—”I think, therefore I am”—he argued that the idea of a “perfect being” in his mind could only have been placed there by an actual perfect being.

For Descartes, the goal of skepticism was to reach a point where God’s existence became a matter of mathematical certainty. He believed that once the mind was “cleared” of false beliefs through doubt, the “natural light” of reason would reveal the divine. While the ancient skeptic found peace by simply stopping the search for the “ultimate nature” of things, Descartes felt that human reason could, through intense labor, bridge the gap to the divine. He turned doubt into a tool for building massive, complex systems of thought—systems that required a new level of intellectual vigilance to maintain.

IV. The Enlightenment: Skepticism as a Methodological Tool

Following Descartes, the 18th century brought about a move toward the empirical. Thinkers like David Hume moved skepticism out of the realm of spiritual exercise and into the realm of probability.

Hume observed that while absolute certainty might be unattainable, human life requires a practical level of belief. He argued that while it is impossible to “prove” the sun will rise tomorrow using pure logic, experience makes it highly probable. This “Mitigated Skepticism” was a survival tactic. It wasn’t about the ancient Ataraxia, nor was it about Cartesian certainty. It was about finding a way to act in a world where absolute knowledge is impossible.

Hume’s skepticism was famously “mitigated” because he recognized that while we cannot rationally justify our belief in cause and effect, we cannot live without it. This turned skepticism from a path to silence into a tool for practical living. Skepticism began to be used to evaluate evidence and moderate dogmatism. This period saw the birth of the skeptic as a social critic—the person who uses doubt to protect the public sphere from unverified or extreme claims. The focus shifted from the internal peace of the individual to the external accuracy of the claim.

V. Modernity and the Active Filter

In the 20th and 21st centuries, skepticism has taken on a primarily investigative role. Often summarized by the “Baloney Detection Kit” popularized by Carl Sagan, modern skepticism is a set of tools used to evaluate the validity of claims in an information-heavy world.

The Investigative Duty

Today, skepticism is an active process of verification and interrogation. In an environment of constant data, the modern skeptic utilizes doubt as a filter.

• The Ancient Skeptic: Viewed a conflict of information as a signal to relax and let go of the need for an answer.
• The Modern Skeptic: Views a conflict of information as a signal to gather evidence, apply logic, and resolve the discrepancy.

Modern skepticism involves a state of perpetual intellectual engagement. To be a skeptic today is to be a participant in the collective effort to refine the understanding of reality. It is a role that rewards accuracy and the defense of evidence-based truth.

VI. The Divergent Paths: A Comparative Summary

The history of these two approaches shows a shift in the lived experience of the practitioner.

The ancient skeptic achieved a form of immunity to the “war of ideas” by simply refusing to join the battle. They maintained a peace that was unavailable to the dogmatists of their time. Modern skepticism, while effective at filtering out falsehoods and advancing scientific knowledge, keeps the individual firmly engaged in the process of evaluation. It is a move from the therapeutic to the methodological.
