 
Form, Substance and Dynamics
Back to basic analysis:
 There are three categories of terms in physics:
 existential terms
 formal terms
 about the structure & static properties of what exists
 dynamical terms
Examples of Formal Terms
 shape, number, form, relation, configuration, symmetry
 function, field, oscillation, wave, flow,
 point, length, area, volume, amplitude,
 vector, matrix, operator, Hilbert space, bra, ket,
 ratios, relative frequency, probability, ...
Examples of Existential Terms
 particle, material, matter, corpuscle, body,
 fluid, ether,
 substance, actuality, reality,
 event, interaction, outcome,
 person, experience, observation, sensation, thought, feeling, ...
 (we know we exist!)
 world, universe, ...
Examples of Dynamical Terms
 cause, propensity, disposition, power, capability, potentiality,
 energy (kinetic and potential),
 mass, charge, field coupling,
 force, pressure, momentum, impetus, elasticity/rigidity,
 (for people: intention, motivation, skill, desire, intelligence, …)

What makes a Complete Physical Theory?
 Our challenge is to describe the quantum world in existential and dynamical
terms, not just formally.
 That is, talk of ‘wave function’ or ‘probability amplitude’ is not really
sufficient.
 Existence must contain/imply some dynamics!
 We want to say ‘what exists’ as well as ‘what form’ it has:

What exists with the wave function as its form?

What is its dynamics?
New idea: ‘Dynamic substance’
Try to derive ‘existence’ from ‘dynamics’
For example:
 ‘electromagnetic force field’,
 ‘potential energy field’
 ‘matter is a form of energy’
 wave function is a ‘propensity field’
 propensity to interact, or
 propensity to choose actual outcome
Propensity (of some kind)
is substance.
