A Critical Point for Science?Lecture to the Cambridge University Physics Society

Basic themes:

• Current physics implicitly assumes matter isfundamental, life and mentality being secondary

• There are reasons for thinking that such a picturemay be incomplete, leading to error

• A new conceptual foundation reverses the order ofthings, making life and mentality more basic thanmatter.

Wheeler’s picture(see The Goldilocks Enigma by Paul Davies)

• Cosmos > Life > Mind > CosmosPicture based on ‘participatory observers’

Physics has always presumed matter

Newtonian mechanicse-m theory/classical mechanicsBasic QMQuantum field theoryString/M theory

• Matter (‘things’) features at every stage

Page 7: critical point CUPS.web - University of Cambridge

What is/may be left out

• Observer problem• Life (complementarity)• Higher cognitive capacities• Paranormal phenomena

Page 8: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 8

Observer issue

What we see is not what we get (from thetheory)

[many worlds problem: the statisticalinterpretation helps only if one avoidslooking too closely!]

Page 9: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 9

Life issue

Measuring a biosystem may change itsproperties (Bohr)

QM provides no clear specification fordealing with ‘unprepared systems’;there is no clarity regarding ‘quantumorganisation’.

Page 10: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 10

Higher-capacities problem

Again, there is little clarity as to how onemight explain, e.g.:

• Mathematical insight• Musical appreciation• ESP, etc.

Gravity problem

• Gravity can’t be fitted into StandardModel

• Extending this to fit makes ‘What YouSee’ still further from ‘What You GetFrom The Theory’ (many extradimensions)

The epicycle saga

• Epicycles gave quantitatively correctresults but were ultimately seen not tobe the right approach: ‘magnitudes arenot everything!’

• Might science similarly be wrong remind and life?

Page 13: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 13

Which is more fundamental?

• Usual view: matter is more fundamental,and life emerges from it

• Alternative: life, mentality etc. emergefrom a more fundamental level ofexistence

Page 14: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 14

Wheeler’s picture

• Cosmos > Life > Mind > CosmosPicture based on ‘participatory observers’Problem: idea too vagueRemedy: find a more advanced

formulation of the idea!

How to make life/mind fundamental?

• Start with a fundamental theory of life Use this as the basis for everything

(instead of starting with a conventionaltheory)

Page 16: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 16

The spinoff, given a proper theory:

• ‘Mind’ would decide what a universeshould be like, not ingenious schemesdreamt up by physicists following thelatest bandwaggon!

• Mind decides on basis of what wouldbest support life, > biofriendly universe.

The Critical PointOrigin of critical-point idea: Samantha Parton on musical

creativity (from interview with Triste magazine):“when you stare into that space and that deepness, you get

close to the place where things begin, and that's a [good]place to be … [for making music]”

Then ...

… an article by Stuart Kauffman et al. inNature reminded me that I had in myoffice a copy of Kauffman’s book ‘TheOrigins of Order’!

Page 19: critical point CUPS.web - University of Cambridge

A different order of things

• Kauffman proposes that life happens at‘the edge of chaos’, a situation poisedbetween order and disorder

• Bohm refers to ‘unmanifest order’becoming manifest

• Rosen refers instead to ‘apeiron’, a‘primal chaos’, from which order springs

Page 20: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 20

Some key concepts

• Edge of chaos• Structures• Differential stability• Attractor• ‘Smart systems’

Page 21: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 21

Smart systems• Stable• Cooperate to form smart complexes• ‘do things’, compute (= I/O + dynamics)• Communicate, make requests, anticipation• Mutual support in a group• Societies live longer• Melt-freeze strategy at edge of chaos• Development of specialisations

Manifestations of mind

• Direct; or• Indirect via universes

Minds and universes

• ‘Deep’ life can use mind to builduniverses

• Mind needs universes thata) It knows how to build (symmetry?)b) Are useful

• Elegance as such is not of interest!

Page 24: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 24

Space and time

• Space: a resource that things can movearound in, provides proximity,separation, place

• Scientist time: a resource that assistssynchronisation, ‘being on time’: timelike that shown by a clock, not ‘actualtime’

Page 25: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 25

Space and time are non-trivial!Space: act of becoming separate

Time: cycles

Space and time represent organisation(Rosen, after Heidegger)

Page 26: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 26

Space-time going cheap!S

pace-time

Universes are created, and organised — somehow!(cf. flocking of birds, termites’ nests)

Creativity

• Can all of creativity (e.g. higher maths,subtle music) be understoodbiologically?

• Does it instead come from our deepersource?

Page 29: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 29

Source of music?

• Place where things begin• Comprehensible ‘germs’• Like a gene, function in a computer

program• Elementary components that can

perform tasks and which we can learnto combine

Page 30: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 30

What are the components of mind?

• Atoms of mind are the units of intelligence,elementary ideas, are ‘physical’ at this deeplevel, come from self-organisation.

• Ideas are systems with a specific innerdynamics, manifesting in their ability toorganise and to create.

Page 31: critical point CUPS.web - University of Cambridge

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 31

In conclusion

• We have proposed an extension ofscience

• Where will this lead?• Will strange, taboo ideas become a

respectable part of science?

Occult Sciences Tripos? CU Institute of Astrology?

Telepathy, ‘memory of water’, ‘cold fusion’?Scientific theology, intelligent design?
