Depressed people often feel “empty” not merely because they are sad, but because depression can alter the body’s energy-regulation systems: immune signalling, stress hormones, sleep, cellular energy production, and the brain circuits that assign value to effort. The result is a felt mismatch between the energy available and the energy a task seems to require.

The core mechanism: effort feels too costly

In depression, the brain’s effort-cost calculation is biased. Tasks that would normally feel neutral or rewarding begin to register as disproportionately demanding, while anticipated reward feels weak or unavailable. This is why “running on empty” is not simply sleepiness: one can sleep for hours and still experience every ordinary action—showering, replying, cooking, speaking—as requiring enormous effort.

Inflammation appears especially relevant to this symptom cluster. Pro-inflammatory signalling can reduce dopamine-related reward and motivation, producing motivational anhedonia: not only reduced pleasure, but reduced willingness to initiate effortful action.
Inflammation and “sickness behaviour”

A major biological pathway involves low-grade inflammation. In depression, particularly in an immuno-metabolic subtype, researchers find elevated markers such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-alpha), alongside fatigue, hypersomnia, increased appetite, and “leaden paralysis.”

These cytokines can signal across the blood–brain barrier and activate microglia, the brain’s immune cells. The resulting state resembles sickness behaviour—the adaptive response during infection in which the body withdraws energy from exploration, social contact, and activity in order to fight illness and repair tissue. In depression, this ancient conservation programme may be activated without an infection that warrants it, producing exhaustion, withdrawal, sleep changes, and loss of interest.

Experimental evidence supports the link: inflammatory challenges such as vaccines or endotoxin can induce fatigue, sleepiness, and anhedonia in healthy people, while interferon-alpha treatment—a deliberately inflammatory therapy—can produce depressive and fatigue-like symptoms.

Stress hormones become miscalibrated

The hypothalamic–pituitary–adrenal (HPA) axis governs the response to stress, including cortisol release. In chronic stress and depression, this system can become dysregulated: cortisol rhythms flatten, feedback control weakens, and glucocorticoid receptors become less responsive.

This matters because cortisol normally helps regulate inflammation and mobilise energy. When its signalling becomes resistant or mistimed, the body may remain in a prolonged defensive state: inflammation persists, sleep and arousal rhythms are disrupted, and the subjective sense of being depleted deepens.

Cellular energy is impaired

“Running on empty” also has a literal metabolic dimension. Mitochondria generate most cellular ATP, and inflammation, oxidative stress, and chronic stress can impair mitochondrial function and reduce the efficiency of energy production.

This does not mean every depressed person has a measurable mitochondrial disease. Rather, it suggests that in some forms of depression, the machinery that converts nutrients into usable cellular energy is under strain. That can contribute to physical fatigue, cognitive slowing, reduced resilience to stress, and the sensation that even minimal exertion depletes one.

Sleep stops restoring

Depression commonly disrupts sleep architecture: sleep may be fragmented, shallow, excessively long, or non-restorative. Poor sleep increases inflammatory signalling, including IL-6 and NF-kappa-B activity, which can in turn worsen fatigue and mood.

This creates a loop: depression disturbs sleep; disturbed sleep amplifies inflammation and reduces daytime functioning; fatigue then makes behavioural activation, exercise, social contact, and routine harder; those losses further entrench depression.
Neurotransmitters and motivation

The older “chemical imbalance” story is too simple, but monoamine systems still matter. Dopamine is central to motivation, reward anticipation, and effort-based decision-making; norepinephrine supports alertness and mobilisation; serotonin affects mood, sleep, and appetite regulation.

Inflammation can interfere with these systems. For example, cytokines can activate the enzyme IDO, shifting tryptophan away from serotonin synthesis toward kynurenine pathways, and can reduce tetrahydrobiopterin (BH4), which is needed for dopamine synthesis.

So the depressed person may not merely “lack willpower”; the neural systems that make action feel worthwhile and feasible may be operating in a low-reward, high-cost mode.

Why it feels like emptiness

Phenomenologically, the experience has several converging sources:

Physical depletion: inflammation, impaired mitochondrial energy metabolism, and non-restorative sleep produce bodily heaviness and low endurance.


Motivational collapse: dopamine and reward-circuit disruption make action feel unrewarding before it is even attempted.


Cognitive fatigue: concentration, working memory, and decision-making require more effort, so ordinary tasks feel mentally expensive.


Stress-system exhaustion: HPA-axis dysregulation keeps the organism in a defensive, poorly regulated state.


Behavioural withdrawal: reduced activity and social contact can further reduce stimulation, circadian stability, and reward, reinforcing the state.

An important qualification

However, the best current account is biopsychosocial: depression-related emptiness arises from interacting biological, psychological, and social processes—not from a single deficient neurotransmitter, and not from a failure of character.

 AI Overview

Emil Cioran’s famous line, “j’ai mal” (“I am in pain”), comes from his 1973 book The Trouble with Being Born. The quote captures his core philosophical view that personal suffering is absolute and completely locked away from the rest of the world. [1, 2, 3]

The Full Quote

“At this very moment, I am suffering—as we say in French, j’ai mal. This event, crucial for me, is nonexistent, even inconceivable for anyone else, for everyone else. Except for God, if that word can have a meaning.” [1]

Key Themes in Cioran’s View of Pain

• Subjective Isolation: Cioran argues that intense pain is deeply private. While others may see you suffer, they cannot feel it; to them, your agony is an abstract or nonexistent concept. [1]
• Pain as Reality: He often claimed that pain is the only true measure of reality. In his view, "Everything turns on pain; the rest is accessory, even nonexistent, for we remember only what hurts." [1]
• Radical Pessimism: Unlike philosophers who try to find a noble or redeeming purpose in suffering, Cioran rejected the idea that pain makes you stronger or wiser. [1]

 

Humans are more like a horde looking for a leader than a herd.

 For Jean Baudrillard, money is not merely a neutral medium of exchange; it is one of the principal engines through which reality is replaced by signs, models, and simulations. Money becomes hyperreal when its value no longer refers to a tangible substance, labour, or use, but circulates as a self-referential code—culminating in credit, digital balances, derivatives, and speculative capital.plato.stanford+1

Money as a sign-system

Baudrillard’s early work argues that commodities possess not only Marxian use-value and exchange-value, but also sign-value: the prestige, distinction, and social position they communicate. A luxury watch is not bought only to tell time or store value; it is bought to occupy a place within a code of status.plato.stanford+1

Money participates in this logic because it is the general equivalent that converts heterogeneous things—labour, nature, culture, knowledge, relationships—into commensurable economic value. In Baudrillard’s account, this abstraction is the first step toward hyperreality: once everything can be expressed in monetary terms, the qualitative differences among things begin to dissolve into a system of interchangeable signs.web.mit

From money to virtual capital

Baudrillard treats money as a “cool medium” that enables participation in the economic system, while itself becoming increasingly detached from material grounding. He describes its evolution into a global system of floating, speculative capital: money no longer primarily measures production or exchange but circulates through financial models, indices, and codes.pages.gseis.ucla

This is why money is hyperreal in a precise sense:

• A bank balance is not a pile of gold or even paper; it is an entry in a database.

• Credit and derivatives refer to future flows, risks, and models rather than present goods.

• Financial markets can move because of narratives, expectations, and signs—a tweet, rating, or rumour—rather than changes in underlying productive reality.

• Cryptocurrency intensifies the tendency: value rests on collective belief in a coded, distributed ledger rather than a physical referent.csmt.uchicago+1

The result is not that money becomes “unreal,” but that it becomes more real than real: its simulated forms increasingly determine what counts as economic reality.pages.gseis.ucla+1

Hyperreality and the end of political economy

Baudrillard’s stronger, later claim is that simulation supersedes production as society’s organising principle. In that diagnosis, money ceases to be the foundation of a stable political economy and becomes one sign among many in a wider circuit of images, information, and models.plato.stanford+1

This marks his break from Marx. For Marx, money and exchange-value arise from commodity production and labour; for Baudrillard, signs and codes increasingly precede and structure production itself. Wages, work, and consumption become markers of one’s position in the system rather than straightforward expressions of productive activity.plato.stanford+1

Sign-value versus symbolic exchange

Money belongs to the order of sign exchange: equivalence, calculation, accumulation, and status. Baudrillard opposes this to symbolic exchange—gift, reciprocity, expenditure, festival, and obligation—which does not reduce relations to price or profit.plato.stanford+1

In his analysis of art auctions, money is “spent” not simply to acquire an object’s use, but to transmute economic value into prestige and distinction. The auction demonstrates how money can be sacrificed or displayed in ways that produce sign-value rather than merely purchasing utility.web.mit

So the relationship is dialectical but pessimistic:

Money’s function	Baudrillardian consequence
General equivalent	Abstracts all values into a common monetary code. web.mit
Medium of exchange	Facilitates participation in consumer and financial systems. pages.gseis.ucla
Store of value	Becomes detached from material referents as credit and digital capital expand. csmt.uchicago
Marker of status	Converts wealth into sign-value, prestige, and distinction. plato.stanford+1
Speculative capital	Becomes a self-referential simulation, helping produce hyperreality. pages.gseis.ucla+1

The essential point

For Baudrillard, money is hyperreality’s most successful simulacrum because it is universally accepted as real while having no stable “original” behind it. It begins as a convenient representation of value, then becomes a model that generates value, desire, debt, and social identity. In the hyperreal economy, we do not simply use money to buy things; money’s signs increasingly organise what we take reality itself to be.

Matthew Segall is a process-relational philosopher working at the intersection of Whiteheadian metaphysics, evolutionary theory, cognitive science, and pluralistic cosmology. His central project is to articulate a metaphysics capable of integrating scientific insight with an ontology of subjectivity, creativity, and experiential depth — without collapsing into either scientific reductionism or idealist monism.

His work can be summarized in five coordinated commitments:

---

1. Metaphysics Must Be Processual and Pluralistic

Segall’s primary philosophical lineage is Alfred North Whitehead, William James, Henri Bergson, and early American pragmatism. From these he inherits:

• Reality is process (not substance).

• Creativity is the ultimate category (not matter, spirit, or consciousness).

• Every actual entity prehends the world (takes account of others, feels relations).

• The cosmos is made of many centers of experience (plural actualities, not one monistic Mind).

Segall deploys this to counter two dominating contemporary metaphysical options:

Against physicalist reductionism

He argues that the attempt to treat matter as inherently dead or mindless is a philosophical fiction that makes consciousness unintelligible and science internally inconsistent.

Against monistic idealism

He critiques the idea that the world is a manifestation of a single universal consciousness (e.g., Kastrup), emphasizing that such monism erases multiplicity, evolution, learning, and becoming.

Segall’s alternative: a many-centered, creative, evolving cosmos.
A “pluralistic creality.”

---

2. Experience Is Ubiquitous (But Not Uniform)

Segall defends a form of panexperientialism (not classical panpsychism). Experience is relational feeling — prehension — and it is basic to nature.

But:

• Experience exists in degrees, not as a universal mind-stuff.

• It is structured, vectorial, and world-responsive, not an undifferentiated consciousness.

• Organisms and higher minds are evolved intensifications of an experiential ontology already present at smaller scales.

This view grounds his broader claims:

• Learning is metaphysically basic (panmatheism).

• Nature is internally oriented, not inert (vector-feeling).

• Knowledge and value emerge from relations, not from detached observers.

His version of panexperientialism is an anti-reductive but also anti-idealist account of experience.

---

3. Evolution, Cognition, and Cosmology Are Continuous

A constant through Segall’s writing is the integration of:

• Whitehead’s metaphysics

• Evolutionary biology and developmental systems theory

• Cognitive science, especially predictive processing and the Free Energy Principle

• Cosmology and physics

His thesis:
The biological, psychological, and cosmological levels differ by degree, not kind.

Meaning:

• Evolution is a story of increasingly complex learning architectures.

• Organisms are self-evidencing systems that maintain themselves by modeling their environments.

• Consciousness is an evolutionary refinement of basic prehensive functioning.

• Physics itself describes patterns of relation and feeling, not dead matter.

Thus, the cosmos is not a brute mechanism; it is a learning process.

Panmatheism (“knowledge everywhere”) appears here as an ontological interpretation of self-evidencing and adaptive behavior.

---

4. Scientific Theories Are Abstractions Rooted in Concrete Reality

One of Segall’s most distinctive philosophical moves is his emphasis on concrete abstraction — the idea that:

• Nature itself performs abstraction (via evolution, selection, constraint).

• Organisms are embodied abstractions of the environments they evolved to track.

• Predictive processing models, Bayesian brains, and effective theories are themselves abstractions constrained by ecological, historical, and biological concreteness.

He argues that:

• Science reveals nature’s structured abstractions, not the “mind-independent world” in a naïve sense.

• Scientific models work because they participate in nature’s own processes of abstraction.

This move allows him to articulate a rigorous metaphysics that honors:

• scientific practice,

• cognitive science,

• phenomenology,

• and evolutionary biology

without collapsing any domain into another.

It’s one of the clearest bridges he builds between Whitehead and contemporary science.

---

5. Metaphysics Without Final Ground (Creative Un-grounding)

Segall insists that metaphysics must not rest on a final substance, ground, or first principle (e.g., “Mind,” “Matter,” “Absolute Consciousness,” “Being”). Instead:

• The ground is creativity,

• which is not a substance but a generative principle.

• Everything emerges from relational processes of becoming.

This gives him room to incorporate:

• modern physics’ openness (indeterminacy, emergence),

• evolution’s historical contingency,

• psychology’s layered complexity,

• and cosmology’s developmental arc.

This “un-grounded” metaphysics resists both dogmatism and nihilism.
It makes space for what he sometimes calls the divine lure toward novelty (Whiteheadian theocosmology) without requiring a personal or doctrinal deity.

---

Structural Summary of Segall’s System

Think of his philosophy as having four interlocking axes:

(1) Ontological:

• Reality = process

• Creativity = ultimate

• Multiplicity = fundamental

(2) Cosmological:

• Universe as a learning process

• Experience everywhere in degrees

• Emergence without reduction

(3) Epistemic:

• Knowledge arises from embodied, embedded abstraction

• Predictive minds = evolutionary abstractions

• Psychic reality is real (not reducible, not literalizable)

(4) Ethical/Political (implicit):

• Rejects eliminativism as nihilistic

• Resists monistic metaphysics as authoritarian

• Advocates relational responsibility grounded in the creative advance of the world

(He seldom foregrounds ethics, but it is present as a consequence of his relational ontology.)

What Distinguishes Segall? (In 5 Points)

1. He is one of the clearest contemporary interpreters of Whitehead.

Not merely exegetical — he updates Whitehead for 21st-century science.

2. He integrates the Free Energy Principle without collapsing into scientism.

He treats cognitive science as metaphysically expressive, not triumphant.

3. He defends metaphysical pluralism against both reductive materialism and monistic idealism.

4. He treats abstraction as an ontological process, not a mental one.

A genuinely novel contribution.

5. He frames the cosmos as a learning, creative, many-centered process.

This is his “panmatheist” contribution to process cosmology.
