This blog post was born to contemplate the meaning of life, as the name itself suggests, but ended up being a repository of everything that my laziness in creating something specific for something that interested me produced, and I didn’t want to face the work of creating something new, and it ended up becoming a mixed bag.
I’m going back to the origins of this question about why the mosquito exists, AI-powered , which will fulfill my intuition and what I can think about it, and which my ignorance would require me to do work I wouldn’t do without AI to bring it to an intellectually decent format.
I will focus on the philosophical/rational/literary aspect, and the subject is “Metaphysical Bestiary,” which has a name that suggests irony, but which actually refers to a concept that combines the idea of a bestiary—a catalog or work that describes animals, often with symbolic or allegorical meanings—with metaphysics, which is an area of philosophy that investigates the nature of reality, existence, and what lies beyond the physical.
⚖️ 1 Scientific explanation, moral justification, and the metaphysical meaning of the mosquito’s existence.
The biological angle — the mosquito as a function in the system of life.
From a rational-scientific perspective , the mosquito exists because it evolved to occupy an ecological niche .
- It is a link in food chains (fish, birds, and insects depend on its larvae).
- It is a vector for diseases , which, paradoxically, regulates populations and puts pressure on the evolution of resistance.
- Its existence is a result, not an end in itself : evolution doesn’t ask “what for?”, only “why?” — the mosquito exists because it functioned in natural selection.
- Although we often think it would be good if mosquitoes disappeared forever, the reality is that the functions these insects perform are essential for life on Earth . The balance that mosquitoes help maintain around the planet makes them indispensable, and therefore our coexistence with them is necessary .
👉 Therefore: the mosquito has a causal reason , not a teleological one. It exists by functional chance , not by moral purpose.
⚖️ 2️⃣ The philosophical angle — the scandal of natural evil
From the Stoics to Leibniz and Voltaire, the mosquito was a symbol of natural evil , that is, of pain that does not result from human action .
- Leibniz would say that it belongs to the best of all possible worlds —even discomfort has its place in a universal harmony known only to God.
- Voltaire , ironically in Candide , would answer: “the mosquito is the living argument against theodicy”—if the world were truly good, why would something so small have the power to kill millions?
- Schopenhauer would see in him the reflection of the blind Will , the irrational force that wants to live even at the cost of suffering for everything else.
- Camus and existentialism would say: the mosquito has no “reason for being,” just like us—absurdity arises from the clash between our search for meaning and the indifference of nature.
👉 Here, the mosquito becomes a symbol of universal meaninglessness : existence as it is , without justification.
🧘 3️⃣ The spiritual angle — the mosquito as a mirror of humility and interdependence
In Eastern and mystical traditions , the mosquito can be seen as:
- A reflection of human pettiness — “if a mosquito has life, who are we to decide who should exist?”.
- A moral test of compassion (Buddhism, Jainism): even the smallest creature feels pain, and its existence compels us to reconsider our everyday violence.
- A symbol of human imbalance : the mosquito only becomes a pest when humans alter ecosystems and disrupt the balance of natural predators.
👉 Thus, it serves as an ethical mirror : the discomfort we feel is a reminder of the arrogance of wanting a world “tailor-made” for us.
🧩 4️⃣ The epistemological angle — the limit of our knowledge
The mosquito poses the question: what is a sufficient explanation?
- For science, an efficient cause is sufficient .
- For philosophy, we want an ultimate reason .
But nature may not have “purposes”—only processes.
👉 Therefore, the question “why does the mosquito exist?” confronts the very structure of human reason , which tends to seek purposes where there are only causes.
It is a reflection of the inadequacy of teleology —and, at the same time, of the human need to ask “why?”.
🎭 5️⃣ The symbolic angle — the mosquito as an existential metaphor
In culture and art, the mosquito often embodies:
- The insignificant that challenges the giant — fragility that overcomes strength.
- The irritating noise of conscience — something small that prevents the spirit from resting.
- A reminder of vulnerability — that even an empire can fall before an invisible virus.
👉 In symbolic terms, the mosquito is the memento mori of our time: not the angel of death, but the buzzing of precariousness.
🧠 6️⃣ General Synthesis
| Perspective | What the mosquito reveals | Type of sense |
|---|---|---|
| Biological | Adaptation and causality without purpose | Functional |
| Philosophical | Scandal of evil and absurdity | Existential |
| Spiritual | Humility and interdependence | Ethical-mystical |
| Epistemological | Limits of rational explanation | Critique of knowledge |
| Symbolic | Fragility and discomfort as a metaphor | Poetics |
🪰 Conclusion
The mosquito is not “useless”: it is a point of tension between meaning and chance , between the order we project and the chaos that surrounds us.It exists—and the simple fact that we ask why reveals more about us than about it.
The angle that most attracts me and that I intend to explore is the idea that meaning is not something that exists in reality, but a projection of the human mind , and that the mosquito is merely a mirror of this rational need to give meaning to what simply is .
The Mosquito and the Meaning of Existence
There are questions that seem naive, but touch the core of philosophical thought.
One of them is: what is the reason for the existence of the mosquito?
The apparent banality of this question hides the metaphysical abyss it opens: if we ask why something exists, it is because we assume there must be a reason . This assumption is the clearest reflection of our rational condition—a reflection that nature, indifferent and blind, does not return.
1️⃣ Reality has no whys — only causes.
From nature’s point of view, the mosquito has no “reason” to exist.
It exists because it was possible , because the combination of mutations, ecological niches, and environmental pressures kept it alive.
Biology doesn’t speak of purpose, it speaks of functionality ; evolution doesn’t know the verb “ought,” only the verb “to survive.”
The mosquito, like any other being, is a successful accident .
And, at the same time, it is a reminder that the world doesn’t need to justify itself.
Meaning is a human invention—a cognitive filter that the mind projects onto the silent flow of events.
2️⃣ The Scandal of Chance
The discomfort caused by mosquitoes is not merely physical; it is ontological .
The mere idea that something so minimal, so useless from our perspective, could exist—and still cause pain, illness, and disturbance—offends the rational impulse of a moral or finalistic order of the universe.
- Leibniz would try to include it in the “best of all possible worlds”.
- Voltaire would reply: the mosquito is living proof of the absurdity of that idea.
- Schopenhauer would see in it the purest expression of the irrational will of life , which reproduces itself without reason, moved only by itself.
- Camus would conclude: there is no meaning at all — and the true human tragedy is to continue asking as if there were.
The existence of the mosquito, therefore, is a metaphor for the absurd :
the collision between our hunger for explanation and the silence of the world.
3️⃣ Meaning as a product of the mind
Human rationality is a tireless machine.
It creates connections, hierarchies, values, purposes—not because they exist in reality, but because our consciousness cannot tolerate the vacuum of chance .
When we say, “What is the purpose of a mosquito?”, we are, in fact, asking:
“Why doesn’t the world organize itself according to my desire for coherence?”
The mosquito has no purpose; we are the ones who attribute one to it .
We call this “meaning,” but meaning is merely a side effect of language , an attempt to narrate a world that does not speak.
4️⃣ The Mirror of Insignificance
Paradoxically, the mosquito reflects back to us what we try to deny:
that we, too, are a conscious cosmic accident .
The difference is that, unlike it, we know we exist and are troubled by it .
The mosquito merely buzzes and bites; we, when bitten, ask “why?”.
And in that question lies all the tragedy and the grandeur of humanity: the animal that demands meaning in a universe that offers none.
🧠 Conclusion: the mosquito isn’t absurd — it’s us who are symbolic.
The mosquito has no reason to exist, but it has a cause.Man has reason to ask, but finds no answer.
Life has no intrinsic meaning; it only has structure , process , event .
Meaning emerges later , like a mirage projected by consciousness onto the indifferent flow of reality.
To ask about the mosquito’s reason is, in essence, to ask about our own reason—and to discover that perhaps neither exists outside the thought that formulates them.

The mosquito, like us, is simply a fact that reason tries to make sense of.
I’ll stop here because I’m entering deep waters that might be too deep to touch, and it’s easy to drown if I don’t have some kind of buoyancy device, which, perhaps unfortunately, my nature doesn’t allow me to do.
