Title: Quantum Theory of the Human Person


1
Quantum Theory of the Human Person
  • 1. The most important twenty-first-century
    development in science will be about the nature
    of human beings.
  • 2. The basic unsolved question there is the
    nature of the causal relationship of mind to
    brain.
  • 3. Von Neumanns Process I and II, applied to
    the human person, constitute genuine causal
    top-down and bottom-up mind-brain connections.
  • 4. Process I involves Free Choice.
  • 5. These Free Choices Can Influence Behavior.

2
The Most Important Question
  • Human Beings Are More Important To Human Beings
    Than Quarks Or Big Bangs.
  • Physical and Mental Health Funding Is Big and
    Growing (16 vs 2.8 of GNP).
  • The Mind-Brain Question is of Towering
    Importance in Neuroscience and in
    Psychology/Psychiatry.
  • Its Legal/Cultural/Institutional/Moral
    Ramifications Control Human Destiny.

3
Mind and Brain in Neuroscience
  • At the start of the new millennium, it is
    apparent that one question towers above all
    others in the life sciences How does the set of
    processes we call mind emerge from the activity
    of the organ we call brain? Antonio Damasio
  • The overwhelming question in neurobiology today
    is the relationship between the mind and the
    brain.
  • Francis Crick.

4
Legal, Cultural, Institutional, Moral
  • Australian Supreme Court Justice David Hodgsons
    book The Mind Matters describes the growing
    effects upon Law of the concepts of classical
    physics. (Recall the infamous Twinkie Defense
    of Dan White for the murders of SF Mayor Moscone
    and Supervisor Harvey Milk.)
  • The thesis that Genes Environment determine
    behavior is not backed up by the evidence. (Books
    by S. Pinker and by J. Schwartz and S. Begley)

5
The Problem of Causation
  • Classical physics reduces us to robots.
  • Intuition insists that mental effort matters.
  • This conflict is the basis of much philosophical
    debate Materialism vs Idealism vs Pragmatism.
  • The issue colors all aspects of our lives.
  • The basic question is the nature of causal
    connection between mind and brain.
  • Bottom up verses Top Down causation.

6
Von Neumanns Process I
  • Process II Generates a Continuum of Overlapping
    Possibilities.
  • Environmental Decoherence Does Not Resolve The
    Problem!
  • The Experimenter Chooses A Particular Action From
    A Continuum Of Possibilities!
  • S ? S PSP (I-P)S(I-P)
  • Discrete Possibilities Yes or No
  • Geiger Counter Clicks or Doesnt Click

7
Process I Free Choice
  • "The freedom of experimentation, presupposed in
    classical physics, is of course retained and
    corresponds to the free choice of experimental
    arrangement for which the mathematical structure
    of the quantum mechanical formalism offers the
    appropriate latitude N. Bohr

8
The Process I Free Choice
  • In Copenhagen QT the experimenter stands outside
    the quantum system.
  • Thus the Experimenters Choice is not determined
    by any known law.
  • Process I is essential to von N QT.
  • Von Neumann places the Process I choice in the
    Abstract Ego.
  • No known law determines the Experimenters Free
    Choice!

9
Effort and Feedback
  • The experimenter exerts an effort that he expects
    will produce a direct experiential feedback, and
    perhaps a response.
  • A human being exerts an effort that he expects
    will produce the feeling and sight of moving his
    finger towards the stove, and perhaps the feel of
    the hot stove.
  • Infants, children, and adults learn by trial and
    error what sort of feeling of effort will
    produce what sort of feedbacks, and possible
    feedbacks

10
Mind_Brain Interaction
  • There is evidently a causal connection between
    feeling of effort and experiential feedback.
  • Non-Interactive Parallelism? (Synchronized
    clocks Geulincx, Occasionalism)
  • Monism? (Mind is Matter is Mind!) But how are
    feelings connected to geometry?
  • Interactive Dualism! (Science has two kinds of
    descriptions. Von Neumanns Process I dynamically
    connects them.)

11
Quantum Psycho-Physical Theory
  • Each course of action conceivable-to-the-agent is
    represented in QT by a P that specifies an
    associated pattern of brain activity.
  • Effortful attention on the action represented by
    P causes rapid repetition of the Process I
    specified by P.
  • William Jamess ideo-motor theory
  • Effortful attention on an intended action
    normally initiates the brain activity that
    produces the expected action.

12
The Quantum Zeno Effect
  • Suppose S describes slowly changing degrees of
    freedom of the brain.
  • Suppose a sequence of freely chosen Process I
    events consist of a rapid repetition of events
    with the same P.
  • Then S is trapped in the subspace of states of
    the form PXP if the original state has this form
    transitions to the other possibility (I-P)Y(I-P)
    are suppressed
  • (I-P)exp-iHt(PXP)expiHt(I-P)O(t squared)

13
Willful Effort Influences Action
  • The rapid repetition of Process I with the same
    P (or slowly changing P) holds the state in the
    form PXP!
  • The essential achievement of the will, in short,
    when it is most voluntary, is to attend to a
    difficult object and hold it fast before the
    mind. Wm. James.
  • Everywhere, then, the function of effort is the
    same the keep affirming and adopting the thought
    which, if left to itself would slip away. Wm.
    James.

14
Effort and Top-Down Causation
  • Within classical physics the efficacy of effort
    is an illusion the feeling of effort
    accompanies the apparent effect, but the causal
    structure is completely explained, in principle,
    in terms of geometric concepts with no rational
    or logical link to feelings of effort.
  • Within quantum theory the free choices by the
    agent can produce a top-down causal effect on the
    brain.

15
Conclusions
  • Von Neumann QT brings physics in line with our
    intuition that our thoughts can influence our
    actions.
  • We are not the robots that classical physics
    proclaimed us to be.
  • The philosophically corrosive conclusion of CP is
    negated.
  • This is just the beginning! (A paradigm shift.)
