Basic themes:
• Current physics implicitly assumes matter is fundamental, life and mentality being secondary
• There are reasons for thinking that such a picture may be incomplete, leading to error
• A new conceptual foundation reverses the order of things, making life and mentality more basic than matter.

Physics has always presumed matter
Newtonian mechanicse-m theory/classical mechanicsBasic QMQuantum field theoryString/M theory
• Matter (‘things’) features at every stage

What is/may be left out
• Observer problem• Life (complementarity)• Higher cognitive capacities• Paranormal phenomena
![Page 8: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/8.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 8
Observer issue
What we see is not what we get (from the theory)
[many worlds problem: the statistical interpretation helps only if one avoids looking too closely!]
![Page 9: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/9.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 9
Life issue
Measuring a biosystem may change its properties (Bohr)
QM provides no clear specification for dealing with ‘unprepared systems’; there is no clarity regarding ‘quantum organisation’.
![Page 10: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/10.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 10
Higher-capacities problem
Again, there is little clarity as to how one might explain, e.g.:
• Mathematical insight• Musical appreciation• ESP, etc.
![Page 11: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/11.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 11
Gravity problem
• Gravity can’t be fitted into Standard Model
• Extending this to fit makes ‘What You See’ still further from ‘What You Get From The Theory’ (many extra dimensions)
![Page 12: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/12.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 12
The epicycle saga
• Epicycles gave quantitatively correct results but were ultimately seen not to be the right approach: ‘magnitudes are not everything!’
• Might science similarly be wrong re mind and life?
![Page 13: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/13.jpg)
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. emerge from a more fundamental level of existence

Wheeler’s picture
• Cosmos > Life > Mind > CosmosPicture based on ‘participatory observers’Problem: idea too vagueRemedy: find a more advanced
formulation of the idea!
![Page 15: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/15.jpg)

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 conventional theory)
![Page 16: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/16.jpg)

The spinoff, given a proper theory:
• ‘Mind’ would decide what a universe should be like, not ingenious schemes dreamt up by physicists following the latest bandwaggon!
• Mind decides on basis of what would best 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. in Nature reminded me that I had in my office a copy of Kauffman’s book ‘The Origins of Order’!
![Page 19: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/19.jpg)

A different order of things
• Kauffman proposes that life happens at ‘the edge of chaos’, a situation poised between order and disorder
• Bohm refers to ‘unmanifest order’ becoming manifest
• Rosen refers instead to ‘apeiron’, a ‘primal chaos’, from which order springs
![Page 20: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/20.jpg)
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: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/21.jpg)
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
![Page 22: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/22.jpg)

Manifestations of mind
• Direct; or• Indirect via universes

Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 23
Minds and universes
• ‘Deep’ life can use mind to build universes
• Mind needs universes thata) It knows how to build (symmetry?)b) Are useful
• Elegance as such is not of interest!
![Page 24: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/24.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 24
Space and time
• Space: a resource that things can move around in, provides proximity, separation, place
• Scientist time: a resource that assists synchronisation, ‘being on time’: time like that shown by a clock, not ‘actual time’
![Page 25: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/25.jpg)
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: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/26.jpg)

Creativity
• Can all of creativity (e.g. higher maths, subtle music) be understood biologically?
• Does it instead come from our deeper source?
![Page 29: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/29.jpg)
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 learn to combine
![Page 30: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/30.jpg)
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 deep level, come from self-organisation.
• Ideas are systems with a specific inner dynamics, manifesting in their ability to organise and to create.
![Page 31: A Critical Point for Science?](https://reader036.vdocument.in/reader036/viewer/2022081604/56816799550346895ddcd5cc/html5/thumbnails/31.jpg)
Mar. 5, 2008/CUPS A Critical Point for Science / Brian Josephson 31
In conclusion
• We have proposed an extension of science
• 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?
