From the publisher’s description, table of contents, and related writings by Manu Bazzano, Difference and Multiplicity: Adventures in Philosophy and Psychotherapy is arguably his most ambitious attempt to weave together existential psychotherapy, phenomenology, psychoanalysis, Zen, Deleuzian philosophy, Simondon, post-structuralism, and political critique into a single vision of psychotherapy.
The book revolves around one central proposition:
A person is not a unified self but a multiplicity—a living coalition of affects, desires, memories, voices, and becomings.
Everything else follows from that premise.
Here are what I see as its major themes.
1. Against the unified self
Bazzano argues that most psychotherapy still assumes there is a coherent “real self” waiting to be discovered or integrated.
Instead he proposes:
- the self is multiple
- identity is provisional
- contradiction is not pathology
- therapy should help people live creatively with multiplicity rather than force coherence.
This echoes:
- Nietzsche
- Deleuze & Guattari
- Simondon
- contemporary affect theory
rather than traditional ego psychology.
2. Difference is something to cultivate
Rather than treating difference as deviation from normality,
Bazzano asks:
What if difference is precisely where life happens?
Difference includes:
- conflicting affects
- cultural differences
- sexuality
- race
- political disagreement
- unexpected desires
- inner contradictions
Psychotherapy therefore becomes less a project of normalization than one of protecting difference from premature closure.
3. Therapy as adventure
One of my favorite aspects of the book is the subtitle:
Adventures in Philosophy and Psychotherapy
For Bazzano,
therapy is not primarily
- symptom reduction
- adaptation
- resilience training
Instead it is an existential adventure.
A therapist accompanies someone into uncertainty.
The aim is not certainty but courage.
This appears repeatedly throughout the publisher’s description:
risk,
exploration,
courage,
compassion,
becoming active citizens of the world.
4. Against integration
One chapter is explicitly titled
Against Integration.
This does not mean celebrating fragmentation for its own sake.
Rather,
Bazzano questions the assumption that psychological health always means producing one harmonious personality.
Sometimes living means remaining productively unfinished.
Multiplicity is not necessarily a deficit.
Sometimes it is vitality.
5. Transindividuation
This is one of the book’s most philosophical ideas.
Drawing heavily on Gilbert Simondon,
Bazzano argues that
people never exist as isolated individuals.
We become ourselves through ongoing relations.
Yet this is more radical than relational psychotherapy.
Simondon’s “transindividuation” means:
individuation always exceeds the individual.
There are
- pre-individual potentials,
- collective processes,
- shared affects,
that continually generate who we become.
Bazzano has developed this idea in a related article, arguing that psychotherapy must move beyond both “psychologism” (seeing only individuals) and “sociologism” (seeing only social structures).
6. Therapy is political
The second half of the book widens psychotherapy into public life.
Topics include:
- climate change
- race
- gender
- colonialism
- neoliberalism
The implication is:
suffering is never purely private.
Psychotherapy cannot ignore
economic systems,
political violence,
or social exclusion.
7. Critique of neoliberal psychology
A recurring theme in Bazzano’s work is criticism of therapy becoming another instrument of productivity.
Instead of asking
“How can I function better?”
he asks
“What kind of life is worth living?”
He is skeptical of therapeutic cultures centered on
- resilience
- optimization
- performance
- measurable outcomes
because they risk serving neoliberal values more than human flourishing.
8. “Legitimate strangeness”
Another memorable chapter title is
Legitimate Strangeness.
The implication is profound:
Not everything strange needs curing.
Some forms of strangeness
are precisely what keep life alive.
This recalls
- Winnicott’s play
- Deleuze’s becoming
- Zen’s beginner’s mind
rather than psychiatric normalization.
9. No hope, no fear
This Zen-inspired phrase also appears as a chapter title.
Rather than optimism or pessimism,
Bazzano advocates
presence.
Neither clinging to hope,
nor being ruled by fear.
This reflects both Zen practice and existential philosophy.
Why I think you, Kelly, would find this especially interesting
Knowing the themes we’ve discussed over many conversations, I was struck by several resonances between Bazzano’s book and your own developing framework.
For example:
What strikes me most is that Bazzano is trying to move psychotherapy from an ontology of identity to an ontology of becoming. Therapy is no longer about discovering “who I really am,” but about remaining open to what one might become through encounters, differences, and events. That shift is deeply influenced by Deleuze, Simondon, Zen, and existential phenomenology, and it aligns with the overall trajectory of Bazzano’s work over the past decade.
