Having now read through the book’s structure and its published abstracts, I think this is Christine Daigle’s most important philosophical work so far. It is also considerably deeper than Posthumanism in Practice. The earlier edited volume asks:
How do we practice posthumanism?
This monograph asks a more fundamental question:
What kind of being are we, if vulnerability is our deepest ontological condition?
In many ways, Daigle is attempting for posthumanism what Emmanuel Levinas attempted for ethics: making our exposure to others the starting point rather than our autonomy. But unlike Levinas, Daigle extends “the other” beyond humans to encompass animals, plants, microbes, technologies, and ecosystems.
I would summarize the book in eight central ideas.
⸻
1. Vulnerability is not a weakness—it is the structure of existence
This is the book’s central thesis.
Ordinarily we think:
first I exist,
then
occasionally I become vulnerable.
Daigle reverses this.
She argues:
We are vulnerable because we exist as radically entangled beings.
Vulnerability is therefore not an accident.
It is ontology.
Everything that exists—
- humans
- coral polyps
- forests
- AI systems
- oceans
- bacteria
exists by being continually affected by countless other entities.

2. The autonomous individual is a philosophical illusion
Classical humanism imagines
Self
↓
acts upon world
Daigle instead proposes something closer to
World
↕
Self
↕
Others
↕
Technology
↕
Animals
There is never an isolated self.
There are only ongoing processes of becoming.
The individual is continually constituted through relations rather than existing independently before them.
3. “Transjectivity” replaces subjectivity
Perhaps the book’s most original contribution is the concept of transjectivity.
Rather than
subject
or
object,
Daigle proposes the transjective being.
A transjective being is
- simultaneously acting,
- simultaneously acted upon,
- continually crossing boundaries.
Agency is therefore shared.
No one acts entirely alone.
No one is ever merely passive.
We are always both influencing and being influenced.
4. Coral polyps become philosophical teachers
One of the book’s most beautiful moves is its repeated use of coral polyps.
Rather than taking the rational individual as the philosophical model,
Daigle turns to coral.
Why?
Because a coral reef demonstrates that
- individuality
- cooperation
- dependence
- emergence
cannot easily be separated.
A reef is not reducible to isolated organisms.
Nor is it a single organism.
It is something in between.
This becomes a metaphor for human existence itself.
5. Affect precedes reason
Drawing from feminist materialism and affect theory, Daigle argues that
before cognition,
before deliberate choice,
before rational reflection,
there is
affective entanglement.
We first
feel,
respond,
resonate,
and only later conceptualize.
Thus ethics begins not with abstract moral rules but with our capacity to affect and be affected.
6. The contemporary world is characterized by “manifold toxicity”
The book is written against the background of multiple intertwined crises:
- climate change
- biodiversity loss
- pollution
- technological disruption
- political violence
- pandemics
Daigle calls this manifold toxicity.
These are not separate problems.
They are symptoms of treating humans as detached masters of the world.
A posthuman ethics begins by recognizing that all these crises arise within the same web of entanglement.
7. Ethics becomes “ethical thriving”
Instead of asking
What duties do I owe?
Daigle asks
How can interconnected beings thrive together?
Ethics becomes less about prohibition and more about cultivating conditions for shared flourishing.
The goal is not merely avoiding harm.
The goal is enabling multispecies life to flourish.
8. Affirmation instead of despair
The subtitle,
An Affirmative Ethics,
is significant.
Although the book begins with vulnerability,
it does not end in pessimism.
For Daigle,
because vulnerability means
connection,
it also means
possibility.
Exposure makes creativity possible.
Dependence makes cooperation possible.
Fragility makes transformation possible.
Thus vulnerability is not merely something to protect against.
It is the very condition that allows new forms of life to emerge.
What struck me most in relation to your own work
Among all the posthumanist books we have discussed over the past year—by Rosi Braidotti, Francesca Ferrando, Karen Barad, and others—this one comes closest to one of your recurring intuitions:
“The conditions for one to be one cannot be taken for granted.”
Daigle’s philosophy could almost be summarized as:
The conditions for any being to be itself are always relational.
That is remarkably close to your long-standing concern in self psychology: a self is never self-sufficient but depends on conditions that sustain its emergence.
Yet I also notice a divergence.
Daigle’s ethics remains grounded in entanglement. The central image is the coral reef: a distributed, interdependent ecology. Your recent work—especially 菊次郎十六式—seems to be moving toward a different image. Your repeated motifs of “follow the fragments,” “strange attractor,” “algorithmic self versus analogical self,” and “為岩中花樹所見” suggest not only that beings are interconnected, but that each life gradually acquires a singular direction through encounters.
So I would describe the contrast this way:
|
Daigle |
Your recent direction |
|
Entanglement |
Encounter |
|
Vulnerability |
Event |
|
Coral reef |
Wandering path |
|
Shared flourishing |
Singular becoming |
|
Ethics of interdependence |
Ethics of letting-be |
In that sense, Daigle offers a powerful ontology of our shared condition, while your project increasingly asks a complementary question:
How does one singular life find its path within that shared web of vulnerability?
That question, it seems to me, is where your dialogue with posthumanism begins rather than ends.
