Hi Bruno Marchal
Good question. It's a difficult question to answer, but here's
my best answer at present.
Monads or substances are the fundamental entites of Leibniz's
universe.
They are all substances of one part.
-----------------------------------------------------------------------
Here's Bertrand Russell's view of Leibniz's definition of substance
http://www.ditext.com/russell/leib1.html#3
"Every proposition has a subject and a predicate.
A subject may have predicates which are qualities existing at
various times.
(Such a subject is called a substance.) "
---------------------------------------------------------------------------------------------
The phrase " predicates which are qualities existing at various
times"
gets me off the hook with regard to wavicles and numbers. Both
quanta and
numbers are substances of one part and so are monads. And all monads,
whatever they be,
must have a fixed identity.
Subject predicate(s)
(of fixed identity)
ordinary matter always both 1. physcal matter 2. mental matter
wavicle either 1. physical matter or 2. mental
(quantum) matter
numbers always 2. mental matter.

Hi Roger,
How can you have a wave without some notion of spatial/temporal
dimensions?
I don't see why we cannot have purely mathematical waves (easily
related to
lines and circles), and physical waves, like water wave or tsunami,
or sound
waves.
A propagating wave is a sort of oscillation contagious to its
neighborhood.
Summing waves gives arbitrary functions (in some functional
spaces), so
simple wave can be see as the base in the space of "arbitrary"
functions
(for reasonable functional spaces, there are any natural
restrictions here).
The whole problem with QM, is that the wave's physical
interpretation is an
amplitude of probability, and that we can make them interfere as if
they
were physical. But in MWI, the quantum waves are just the map of the
relative accessible physical realities. An electronic orbital is a
map of
where you can find an electron, for an example.
I would say it is something physical (even if it emerges from the non
physical relations between numbers).

Hi everything-list,
I don't believe that Descartes would accept the MWI.
Here's why:
I think that the ManyWorldsInterpretation of QM is incorrect,
due to the mistaken notion (IMHO) that quantum waves
are physical waves, so that everything is physical and
materialistic.
This seems to deny "quantum weirdness" observed
in the two-slit experiment. Seemingly if both the wave
and the photon are physical, there should be nothing weird
happening.
My own view is that the weirdness arises because the
waves and the photons are residents of two completely
different but interpenetrating worlds, where:
1) the photon is a resident of the physical world,
where by physical I mean (along with Descartes)
"extended in space",
2) the quantum wave in nonphysical, being a resident of
the nonphysical world (the world of mind), which has no
extension in space.
Under these conditions, there is no need
to create an additional physical world, since each
can exist as aspects of the the same world,
one moving in spactime and being physical, the other, like
mind, moving simulataneously in the nonphysical world
beyond spacetime.
