Some skeptics have suggested that the specific peptides endorphin and
enkephalin may be released in the brain during the dying process and that
their stress-reducing effect may account for near-death experiences.40 But
the timing doesn’t work. The course of near-death experiences is often very
quick, but endorphins and enkephalins have relatively long half-lives; they
decay slowly over minutes or hours. Therefore, the experiences they induce
would tend to dissipate only very slowly. In near-death experiences, pain
and uncomfortable feelings return instantly when the soul reenters the body.

Here’s a bullet-point gist extrapolated from your passage:
-
Conflict between camps: Philosophers and scientists disagree about whether the mind is just the brain.
-
Identity theory claim: Mental states (e.g., wanting to take an umbrella because of rain) are identical to physical brain states (neuronal/electrochemical configurations).
-
Problem of mismatch:
-
Mental states relate to each other logically (belief → action makes sense).
-
Brain states relate to each other physically (chemical and electrical processes).
-
-
Core gap: The laws of chemistry and physics don’t inherently contain the laws of logic.
-
Implication: If the mind is only the brain, it’s unclear how logical thinking could arise from purely physical processes.
Do you want me to expand this into a short schematic/diagram-style flow (showing the logical vs. physical gap visually), or keep it strictly as text bullets?

For example,
University of California–Irvine cognitive scientist Donald Hoffman, author
of The Case Against Reality: Why Evolution Hid the Truth from Our Eyes
(2019), explains that we evolved for survival, not for apprehending reality:
It leads to a crazy-sounding conclusion, that we may all be
gripped by a collective delusion about the nature of the material
world. If that is correct, it could have ramifications across the
breadth of science—from how consciousness arises to the
nature of quantum weirdness to the shape of a future “theory of
everything.” Reality may never seem the same again.18

Here’s an elaborated bullet-point gist of the passage:
-
Donald Hoffman’s thesis (The Case Against Reality, 2019):
-
Human perception is shaped by evolutionary survival, not by a direct grasp of objective reality.
-
-
Implication: What we perceive as “reality” could be a useful interface, like icons on a computer desktop, rather than reality itself.
-
Radical consequence: We might all be experiencing a collective delusion about the material world.
-
Scientific impact: If perception doesn’t mirror truth, this challenges:
-
Theories of consciousness (how experience arises)
-
Interpretations of quantum physics (“quantum weirdness”)
-
Efforts to construct a unified ‘theory of everything’
-
-
Takeaway: Accepting Hoffman’s view would mean rethinking our most fundamental assumptions about reality itself.
👉 Would you like me to contrast this with the mainstream view (that evolution does track truth, at least approximately), so you get a fuller picture of the debate?
