Irreversible process
“All complex natural processes are irreversible” means:
👉 Once they happen, they cannot be perfectly undone to return everything to its exact original state.
This idea comes from physics—especially Thermodynamics—but it applies much more broadly (biology, psychology, history… even your “van life” thinking).
1. The Physical Meaning (Entropy)
At the core is the concept of
👉 Entropy
- Entropy roughly means disorder, dispersion, or spreading out of energy/information.
- The Second Law of Thermodynamics says:
In a closed system, entropy tends to increase.
So:
- Ice melts → water spreads out
- Smoke disperses → fills the room
- A glass shatters → fragments scatter
All of these processes:
- happen naturally
- but do not spontaneously reverse
You can refreeze water or rebuild a glass—but:
- it requires external work
- and you never recover the exact original state
2. Why “Complex” Matters
Simple systems can look reversible (in equations):
- A single pendulum swinging
- Idealized frictionless motion
But real-world processes are complex:
- billions of particles
- interactions across scales
- tiny fluctuations amplified
👉 Complexity = information gets lost into the system
Once lost:
- you cannot reconstruct every detail
- therefore, you cannot go back
3. Everyday Intuition
Irreversibility shows up everywhere:
- You can’t “unmix” milk from coffee
- You can’t “unburn” paper
- You can’t return to yesterday with the same mind
Even if you recreate the appearance:
- the underlying micro-state is different
4. Time’s Arrow
This is why we feel time has a direction:
👉 From past → future
👉 From lower entropy → higher entropy
This is called the arrow of time
Without irreversibility:
- time would feel like a loop
- memory, causality, history would collapse
5. A Philosophical Turn (closer to you)
Now, if we translate this into your language:
- Ereignis (event) happens
- It cannot be “un-happened”
- It becomes history, wound, trace
So:
A life is irreversible
A session is irreversible
A word spoken cannot return to silence
This aligns with what you’ve been circling:
- “被事件事件”
- trauma → event → problematique
Irreversibility is what makes:
- ethics necessary (you cannot undo harm)
- witnessing meaningful (you stay with what cannot be reversed)
6. A Quiet Reformulation (in your tone)
Let me say it in a more 菊次郎式 way:
水倒在地上，
不是問題。
問題是，
你還想把它，
倒回杯子裡。
——
於是你終於明白，
生命，
不是修復，
而是承受。
If you’d like, we can go one step further (this would fit beautifully into your system):
👉 map irreversibility → 菊次郎十六式的臨床 micro-gestures
(i.e., how a therapist acts differently once they truly accept that nothing can be undone)
That would be very precise—and very quiet.
