. HISTORICAL NOTE
The best that has been
said, perhaps,
about cause andeffect,
wassaid the most
simply
in statements like thefollowing by
ETIENNEGILSON ;
« Where
.there
is efficientcausality, something
new, which we calleffect,
isbrought
into existenceby efficacy
of its cause » . There las been consider- able discussion on thequestion
whether thissomething
isalways unique.
Since any answer to the
question
will involvelogic,
and causeproceeds
from some
reality
as abeginning,
and effectpredicates
someend,
we firstconsider the nature of some
possible beginnings
ofthouglt concerning causation,
and certainpossibilities
for classification of realities.Our attention will be
required
to atype
ofnullity
callednon-effect
and some illnstrations of the null may well be mentioned first. In a
proof
of any formula
by
mathematical induction webegin
with aspecial
case inwhich a
special
value of eachparameter
in the formula is iu the properplace
for thatparameter,
so the law of the formula can be abstracted.Thus to prove,
we may start with the case
(a +
or(a + b)2,
but not with the null case,(a -~- b)°.
The latterexpression
has to bearbitrarily
defined and then is’
out of
conformity
with the binomial law.The
representation
of thepositive integer
M as apolynomial
in anarbitrary integer k
as abase,
ispossible uniquely,
for if we couldhave,
x’ - x would be divisible
by k, Dividing
out k from what is left in(2), 1 ’ = 1 , .. , a’ = a ,
which is aproof.
Hence wewrite,
but if some
term, as fl )cm-l,
is notactually present,
in the case of the ][Ichosen,
asymbol 0
is inveiitedhaving
the character of apositive integer
and the
property
that it nullifies any term of M that has it as coefficient.If no other term is
missing
we then have Munchanged,
thatis,
but the existence of the zero is a
postulate;
also thesimplest beginning
To make the
algebra
of classeslogically complete, (i)
it was foundnecessary to introduce the null
(enpty) class, whereupon
it became expe- dient to revise Aristotelianlogic.
But the null class cannotfigure
as thebeginning
of an induction :The
orderedsystem E of types
ofreality.
KANT mentioned the fact that the
weight
of onobject
issomething
that remains outside
the object,
whilestanding
in some connection with it.The
judgment
that theobject
has theweight
istherefore,
in the usualterminology, synthetic,
and thisprinciple
has beenshown, by
thewriter (2)
to establish a classification of the
totality
of existent realities.For,
in thecase of any two
realities,
thejudgnent
that A has B issynthetic
if B iswithout A
(and analytic
if B is’covertly
contained inA).
If we rule that B lies above A whenthe jndgineiit
issynthetic,
thetypes
ofreality
areordered into a of
degrees
in which the’ realities essential to anydegree
aresyntheses
fromrespective
realities of thepreceding degree. By
this rule alone E can be ordered in the form of a succession of ten
degrees
of rank n
extending
from 0 to9,
space and timeforming
the realities ofzero
degree.
We herereprodiiee -Y,
from our earlier paper;also,
for illus-tration,
formulations like asyllogism connecting
onedegree
with the nexthigher,
thatis,
thestep
from(E)
to(~) ,
it = 5 . There are realities withoutsynthetic
connections is the sense but these same realities will haveanalytic
connections in I.’ (i) R. OSBORN, Mathematics Magazine, vol. 26, (1953)y p. 175.

iii regarding
areality
as intuitiverepresentation,
y(abstraction),
in acognition,
y the latterconsisting
of aconcept plus
itsrepresentation.
We avoid fundamentalism in discussion of the apriori, (3).
This .province
of the mind was built upevolutionally
before the dawn ofhistory,
and it is thereforepre-history
that maintains it now. Pre-historicman did not know, of course, wlat an
objective reality
was. It was he whofirst said Ich verstelie nicht einmal was ein
Ding
ist >>.Nevertheless
hecould
represent
aconcept
of areality
in his sensuous intuition. This we stilldo,
but the mind has notstopped
there. We arefinding
outsomething
about
things
inthemselves,
aboutfreedom,
lifeitself,
and so on. Thishistoric
something
is notyet engnossed, evolutionally,
on the scroll of thea
priori.
It remains asempirical generalization,
intuitiveexcepting
whathas been made
conceptual by
actual inductiveproof. During
historicaltimes wave-intuition has
developed perhaps
more than any other function of the mind.However, reality,
which ispretty generally
a manifestation of energy, has been found to beinseperable
from thethought concerning
it.The

However,

asimplied by
thephrase
« a senseof »,
while it will be connected with a subliminal mentalreality [E],
it will not be apart
of[E].
It is anunproved

Thejudgment

lies above(E)
in 1.The reader will wish to consult the authors
previous
paper for corre-sponding
verifications of the othereight syntheses,
andperhaps
HEGEL’Stheory
ofsynthesis
also. The theorem on theuniqueness
of connection has beenproved only
for thesynthesis (a , fl),
where it takes the form of aknown theorem in the calculus of
variations,
viz. Aunique (straight)
lineis the shortest distance between two
points
in space. Here thisreally
means two
points
in(fl). Any degree
in ~ may contains anyreality
from alower
degree in
but none that is essential to anyhigher degree.
In will be noted
that,
within(a) ,
since space affords us nocognitions (KANT),
we are unable torepresent
any extension[AB]
from aspatial point
A to aspatial point
B. To use ageometric
line AB would be todepart
fromdegree (a)
todegree (p) (CLIFFORD).
The former conclusion is consistent with intuition. Measure is relative to motion of the extensionmeasured,
and the earth has two kinds of motion. The solarsystem
as awhole is in motion. On the other
handy
relativitistsquestion
whether there is any suchthing
as absolute motion.Hence,
anyattempt
torepresent [AB]
in(o&)
becomesnaturally illusory,
thatis,
null.Non-effect
Non-effect is a state of a combination of realities when no law is
operating
upon it to effect anotherreality.
As one can
verify by
asimple experiment,
H,large objective reality,
falling
in a vacuum toward the center, of theearth,
has noweight
while itis
falling.
It is a combination ofobject
with thephenomenon
offalling,
and is a state of non-effect. ARISTOTLE siiid that the
planets in
their orb- its had no attractiontoward
the center(suu).
FRANKLINsuggested
that itmight
some time bepossible
todeprive
anobject
of itsweight
aod move itabout
easily
fromplace
toplace. (4)
A
planetary body P,
in itsregular plane orbit,
is in a, state of non-ef-fect, dynamically.
It tries to fall into the sun butgot
startedobliquely.
The
negative
of the vector PV of the radialcomponent
of thetangential
inertial
force, equals
the vector PW of the central forceF (r),
y(See Figure I).
The
equation,
is the condition for orbital
stability.
But it is knownthat, (5)
Eliminating
t between PV and the differential form of KEPLER’S law of areas,r2 d 8 = h d t,
I theequation (3) becomes,
which is the known
equation
for central orbits.An inward
perturbation
of the,orbit,
atP,
7 isequivalent
to an increaseof PW .
Stability
thenrequires
an increase in- PV ,
y which is to say thata force of reversion arises.
(The principle applies
tospatial
orbitsalso).
In the case of the
unperturbed
orbit there is neitherweight
towardthe sun nor force
along
thetangential
direction. The idea that there must be anintervening
medium ofgreat
tensilestrength,
betweenplanet
and sun, seems therefore to be false.Apparently
auysystematic
motion in nature issubject
to a force ofreversion toward some state of non-effect. An
atom,
considered as asystem involving
electrons in motion likeplavets,
is a state of non-effect that will continue for an indefinite time unless an external force intervenes. The seed of aplant
is a state of non-effect with atendency
to beperpetual.
Under some conditions a
grain
of wheat may retain its power togerminate
for a thousand years. When it does
germinate
it isonly
to return to anothergrain,
which will be the same state ofnon-effect,
after a fixedcycle
of events.(4) BENJAMIN FITANKLIN, Letter to Joseph Priestley, (1780).

The
cycle
of events after an orbit isperturbed
If a
planet
runs into acomparatively
small alteration of its usual fieldof force, its subsequent
niotion will include acycle
,ofdiminishing
vi-brations transverse to its
original
orbit. Itspath
settles into a state ofuou effect
which, according
tocircunistaiices,
may or may not coincide with itsoriginal
1 orbit. -For historical reasons
mainly
we mention also acontemporaneous theory
ofvibrations,
also transverse to theorbit,
but borneby
ahypothe-
tical
aether, and,
in someunspecified
manner,keeping
pace with the mo-tion of the
planet
orcorpuscle.
These vibrations or waves have been repre- sentedby
means of apair
of vectorsD ,
7 j67 drawn from themoving body considered
’as apoint
andsatisfying
fourequations
which have beenobscurely
said torepresent
the state of the aether ». Theequations

We would want toduplicate
the wave motionby
a chosen oscillation of the axes. Hence the

Now it is known that any curved orbital
segment,
for any astralbody,
can be considered as a central
orbit, (7)
witlinacceptable approximations,
and so will have ao associated force of reversion. A
straight
orbit of alight corpuscle,
considered as theboundary

plane orbits, slightly
curved away from theboundary (or
considered asthe central filament of a tube of orbits all of wicich are

that ~5y may beregarded

For when we trans- forrn Sby T1 (u1 ~ v1 ~ w1)

by solving

that,

as must be the case if the transformation isby Uo ~

into existence if aperturbation

applied
and the electrons recede torespective
orbits of a new level of energy,according

1 .From the
point
of view of mathematical culture it is fundamental thatwe can have an
operator
U whichfigures
as a causal law and the effectof which is
non-unique,
but when this law combines with its relevantobjective reality (a planet
in its state ofnou-effect),
theoperator picks
upa sufficienf revision or fulfillrnent to inake the effect one
thing
or the otherbut not
both,
that is to say, makes it either a secularperturbation
ofthe original
orbit or a finite shift to a different orbit. In this and the pre-ceding
section we have shown how twophysical phenomena, relating
toorbits,
conform to the usual law of cause and effect. The inference had beenquestioned.

Concerning

An effect may be
compound,
with one effectoccurring
as a concomita,nt of another. What is described above as avibration,

contains the effect calledfrequency.

conclusion
is coiisistent with results in the authors paper of 1937 iu the Annali of the Pisan Scuola NorinaleSuperiore, (vol. 6,

in the case of a stable

the force of reversionwhich, along t-

The conclusion thatsome materials are forms of energy, y or
nearly that, gives siguificant unity
to our scatea of realities 1. For it is evident that the realities in any

forms of energy. This leaves the
space-time
order(a)
as theonly
nne wherethe
specific
realities are notexpressible
iu terms of energy, unless it canbe shown that space is a cache for latent energy, wlich seems
improbable.
For a more
empirical reference,
in one case, asimple
snbsistentialreality
,
(8)
may be considered. Itsprimary
function was to aidself-perpettlation
ofa
phenomenon,
but theouly thing
that could beardirectly
upon apheno-
menon~ considered as an occurrence and therefore as a manifestation of energy, would be another manifestation of energy. Hence the assumedreality
in

would bedescriptable
in terms of energy. ,In a

representation
could be in a lowerdegree
but agiven degree
can include realities of any lower
degree.

An element of subliminalmentality

can bedepicted
on a chosenreality

One could choose aspecific

an then find that agiven reality (~) ,

hadnothing

we could state that not allspatial extensions,

Mathematical laws
play a leading part
in the rise of many if not of all causes. We here mean deterministic and notprobabilistic
mathematical laws. KAN1’ has written that it is notmanifest,
apriori, why reality,
ingeneral,
shouldpresent
the case of aspecific reality A,
as cause, asbeing
connected with a second
reality B ,
aseffect, by
law. It isprobably
truethat no
specific reality,
ofitself,
causes a secondreality.
If so the secondreality
mostlikely
would havepiled
up on the earth. Areality
becomesinvolved in a cause when it is its fortune to combine with a relevant law of
combination,
and we can go along
way with thehypothesis
that thislaw is
always,
iii itsesseutials,
mathematical.An element that is
necessarily conjectural
may well be introducedhere,
in the forrnnlation. We assume that intuition functions like a mathe- matical law associated with the atomism of thebrain,
and acts on occasionin combination with a
reality
toproduce
a cause, in the manner character- istic of mathematical laws whichproduce
causesby aligning
themselves, withrespective
relevant realities.Light effects,
as we havenoticed,
exist inconformity
with the rulestated,
as effects of combination ofspecific reality
with relevant mathemat.ical law. BERTHOUD has iden ti fied the fundainentals in chemical
chantey
under the
principle
of the conservation of the chemicalelements,
with per- turbations of the electronic orbits within theatoms,
and theseperturba-
tions follow mathematical laws. An electron may be iu a
given vicinity
and a proper nucleus may be
incipient
theretoo,
butonly
the mathematical law of central orbital motion can cause the electron toproduce
an atomas its effect. The process in
general
may be statedformally :
The law Lcombines with the
reality
toproduce
a cause the effect of which is areality b .
Thereality a
may be a combination ofrealities, (1°)
in a state ofnon-effect. Also it seems to be true
always
that transition from cause to effect is itself areality (y),
thatis,
aphenomenon.
