Paper presented at the
42nd Annual Conference of the
Jean Piaget Society
31 May – 2 June, 2012, Toronto, Canada
Conference Theme:
Rethinking Cognitive Development
I. Piaget as Epistemologist —
(Knowledge Theorist)
•
XEPISTEMOLOGY
• What is knowledge?
• How is it assembled?
• x(& by what mechanisms?)
• How does it relate to the
x reality it “depicts”?
• How are advanced ideas
“written” and retrieved?
• XXXXXX etc.
(a)
His main agenda -- & ours:
xxxxx Knowledge in ●the Brain
(b) but also agenda in a 2nd domain:
x Knowledge in ●Science / Society
(c ) Then there are 2+ further xxx
Knowledge-learning domains
1
(“epistemologies”):
xx●Immunology & ●Darwinian Evolution
•
•
X “Training”
x antibodies
D NA
(c ) That makes 4+ altogether. xxx
(Each offers helpful analogies):

II. Use Piaget’s Approach to
the“Science domain”
   
to enhance his Account of
the “Brain domain”
i.e. …
II. Can JP’s “Science domain” tackle
deep mysteries of his “Brain domain”?
• (d)
• Note the scientific
vagueness of most
psychology concepts:
• x Ego, motive, … ,
x & even Scheme
• Is there a cure???
?ψ?
?
(e) Science just by Observation? x
Piaget (& Hume) saw that as naive:
• “Popperians” insist on direct observation
BUT: 
• Hume (1748): that’s never rigorously sound
• Piaget (1949) Traité de Logique; (intro.)

(j) Piaget’s potentially stable
element-of-thought = “Schème”:
• Each is a hypothetical brain-encoding for some
__specific action-sequence, including:
• Internal & External actions
• Overt & Covert
actions
• Genetic & “Learned” actions
• Each Preformed:
--------- “In the beginning was the deed!” (Faust / Furth!).
• Such spontaneous “Trial & Error acts” (chez l’enfant)
- seem comparable to Darwinian Trial-&-Error

IV. Implications & Consequences
(m1) Possible 1D material schemes:
•
•
•
•
•
Very specialized strings of neurons !? – Never seen? – inefficient+vague
Protein? – too lumpy! – and too like bricks!
PNA? – too rare and unstable??
DNA (basic code)? -- too stable!
DNA (epigenetic switch-setting)? -- Maybe in part. See below!
• RNA? Best guess:x ●Mediumxstability
x●Flexibility x
x●97% available as “ncRNA” for this-&-as-regulators!!
xx(Mattick 2000+). [Only 3% used as protein-templates!]
x●Direct evidence of involvement (Hydén 1967+, etc.),

(n1) Pre-1980 belief in RNA-role
for memory
Hydén (1967+) and others showed that RNA-changes did
accompany learning.x–– But why largely forgotten now??
The problems seem to have been:
●Everyone assumed that RNA was merely an aid
to synapse-changes – [actually autonomous?]
●No plausible mechanisms – except very vague!
●Distraction over perhaps-irrelevant experiments on
injecting “RNA-memory” into naïve animals.
●In short: The ideas did not really make sense.
But now it seems timely to reconsider such work;
& Piaget himself took it seriously (“Biol.&Knowl.” 1967).

(o1) So de-throne synapse as THE
key element – (of intellect at least)
Key Elements for our intelligence-coding?
Synapse? No!
RNA? Probably!
Yet Synaptic systems still clearly have vital roles:
● Contact with outside world – Obviously!
● Pattern-recognition (copied commercially!)

● IF such coordinating signal-networks exist,
xxxmight these also confer mutual stability???
(If so, this could help explain self-organization
of Long Term Memory)
(q1) Efficient communication for
such sites? – Needs infra-red (IR).
Serious Technical Hitch:
• The textbook “voltage-spike” signals are much x---too coarse for sub-molecular code-sites !!
• Natural quantum-jumps for such sites would
---require infra-red photons instead !!!!!
That clue quickly leads to new realizations:
• Myelinated nerves  co-axial cables for IR!
• Vastly improved “broadband” now available!
• =? “ultra-weak” IR photons known since 1923!

These allow a radical re-think, e.g.
Now feasible for memory-“writing” to
be a Darwinian choice from many waiting
pre-schèmes, thus solving the “write” enigma!

(t1) Deliberate design? Sometimes:
if one domain interferes with another:
• Obviously
when our
human brains override
the randomness of:
natural immunity
genetics
the apparent autonomy
of Social institutions!!!
• But intention & design
within the Brain itself?
Suppose some Schèmes
get the sole role of
directing the “normals”
(so now less random)
That offers a
1st step to
design and
intelligence.

So Pre-op. alters Sensori-motor, etc.
NB – The cascade
of “interference” –
Apparently the key
to human
intelligence
Formal operations

its own Schèmes
Concrete operations
subdomain with
its own Schèmes
Pre-operational
subdomain with
its own Schèmes
Sensorimotor
subdomain with
“Normal” Schèmes
(z) Unforeseen “spin-offs” from
the idea of Infra-Red involvement!
That’s another story – not today!
[Morphology, Optical interference effects etc.
See (2011a) paper – J.Phys.]
BUT TO SUM UP:
SUMMARY
1. Piaget’s epistemology helps Science-study.
2. So let’s use his method on his own Brain-study
(of which the detail has been impossible to “observe”).
3. Conclude: Key Element = RNA (not synapse!)
4. And
Key internal-signals are INFRA-RED
5. This offers a 109-fold increase in efficiency!
6. & … a Darwinian “recording” technique;
7. + … seems to solve enigmas in other bio-fields,
including design-ability – and morphology.
