Abstract
Emergence may be defined as the point at which an entity is subject to a new and different class of
rules. Given that we can describe entities at one level (e.g. the properties of hydrogen and oxygen) in
terms of their probable rules of behavior, and can describe entities at a higher level (e.g. the properties
of water) in the same manner, the essential question of emergence becomes "How does an entity
become subject to a completely new and different set of rules?" This paper describes the notion of
emergence operationally, by means of a very simple "emergence rule" that declares the existence of
new entities whenever existing entities achieve certain defined statuses. Conversely, any time an entity
becomes subject to a new and different class of rules, it operationally becomes a new entity. Entities
change statuses only as a by‐product of processes, which processes can perform only "addition" or
"subtraction" in the broadest senses of the words. Under this approach, there exist two broad classes of
phenomena: those that follow the classical rules of arithmetic (called resultants), and those that don't
(called emergents). Both of these may be described by means of qualitative, conditional rules. The
paper illustrates these concepts with examples of emergence from intentional systems (the U.S.
Constitution) and natural systems (basic chemistry).

Introduction
The paradoxes of complexity, and in particular the phenomena of emergence, have forced me to
reconsider how we represent the basic and ubiquitous transactions of addition and subtraction. My
conclusion to date is that we must create another "grammar" that distinguishes resultant from
emergent1 transactions.
The class of transactions that I will call resultant transactions causes no real difficulties for modern
quantitative notation. These transactions arise when two or more entities can be "added together" in
any order, and their interaction is zero or negligible. In these transactions, one plus one equals two,
now and forever; in other words, they are additive simpliciter. In pure arithmetic, this denotes the
union of two sets; in the real world, it may refer to two entities being mixed, or placed nearby each
other, or in some other sense "added". The notational systems that have been built around numbers
presume the following:
entities in toto can be added or subtracted simpliciter in all interesting cases
properties of entities can be added or subtracted simpliciter in all interesting cases

such transactions are commutative (i.e., that adding A to B is identical in effect to adding B to A)
they are associative (i.e., that adding A to B and then to C is identical to adding B to C and then to A)
they are monotonic (i.e. if A < B, then A + X < B + X)
they are reversible (i.e. that if A has been added to B, then A can be subtracted from B to derive
separate entities again).
These transactional presumptions hold true of all vector spaces, i.e. all sets "of objects or elements that
can be added together and multiplied by numbers (the result being an element of the set), in such a
way that the usual rules of calculation hold" (Gellert et al, page 362). They work quite well for the
natural numbers, for many other kinds of mathematical entity (e.g. angles), and for many entities in the
real world (e.g. unbalanced forces); but many transactions in the real world do not fit these criteria.
Such transactions ‐‐ for which I will hijack the phrase emergent transactions ‐‐ occur when two or more
entities are "added together" or "subtracted", and their interaction is significant. There are several signs
that indicate when an emergent transaction has occurred:
the resulting number of entities cannot be inferred from the number of the components (the quantity
of the sum cannot be computed from the quantities of the summands)(i.e., a unit increase in summands
produces a non‐unit increase in the sum2)
the resulting properties cannot be inferred from the properties of the components (the properties of
the sum cannot be computed from the properties of the summands)
the order of addition (or subtraction) is significant and is not reversible.
The transactions that have created matter, life, society, consciousness ‐‐ and perhaps even notations like
number3 ‐‐ are emergent transactions. The classic example is the combination of two flammable gasses
‐‐ hydrogen and oxygen ‐‐ to form a non‐flammable liquid: water. An example of non‐commutativity is
the addition of water to acid versus the addition of acid to water.
One of the seminal thinkers about emergent evolutionism, C. Lloyd Morgan, suggested that emergent
transactions produce qualitative changes; but I observe that they can also create quantitative changes.
Conversely, resultant transactions also produce qualitative changes, such as the addition of blue and
yellow watercolors to make green watercolor. Figure 1 illustrates the key distinctions between a
resultant grammar of interactions and an emergent grammar:
Resultant Resultant Emergent Emergent
Grammar Grammar Grammar Grammar
Addition Subtraction Addition Subtraction
Quantitative 1 + 1 = "11" = 2 "111" ‐ 1 = "11" 1 + 1 = ¬2 2 ‐1 = ¬1
Qualitative A + B = "AB" "ABC"‐B= "AC" A + B = C C ‐ B = A, B

-- Thus non-linear transactions are a subset of emergent transactions.

-- In January 1994 I gave a talk exploring the idea that notations are real in the Platonic sense of being pre-existing
rather than emergent. I confess I am presently confused about my beliefs in this area.

and water plus heat makes steam. Thus we may model an entity (e.g. water) plus attributes (e.g. state);
but because the resultant acts so differently, we treat certain cases as distinct entities each subject to
their own rules. It does not matter whether the new entity is apparent or real; only that it behaves
differently.
In a strictly descriptive sense, we can imagine a notation having a grammar whereby adding or
subtracting Entity X and Entity Y does not follow the classic (resultant) grammar of arithmetic. By
definition we cannot specify what any two (or more) entities will add up to; thus the properties that
emerge must be declared; they cannot be deduced. And they must be stated contingently, as
conditional rules. Furthermore, "adding" cannot be treated as an abstract operation, because in fact
what is being added matters: we must define more concrete operations such as "added to X", "added to
Y", "added to Z", etc. Each such situation can then be treated as a predicate of an entity: i.e., a status.
Thus, in the general case,
If Entity X acquires status C, then it (becomes) (is treated henceforth as) New Entity Y.
Examples are:
X = bill, C = approved by House, Senate, and President, Y = law
X = ordinary citizen, C = wins election, Y = U.S. Senator
X = U.S. Senator, C = loses election, Y = ordinary citizen
X = hydrogen, C = added to oxygen, Y = water
X = water, C = heat, Y = steam
X = pawn, C = reaches 1st rank, Y = queen.
I call these "emergence rules", and the class of such rules I call an "emergence ruleform", for by
effectively redefining (renaming) the type of entity one is dealing with in an Ultra‐Structure model, that
entity becomes immediately subject to completely new and different rules. This and like facts cannot be
expressed in mathematics, which is the notation of resultants; it can only be expressed by a contingent‐
rule‐expressing notation such as Ultra‐Structure.
In the most general case, for every permutation of statuses that an entity may have, it may be subject to
new and different classes of rules. Therefore if its status changes for any reason (including the mere
passage of time), it (or the new entities it becomes) may behave in unexpected ways. Perhaps it is for
this reason that the general semanticists like to index words: so we don't always presume that an entity
at t=1 is the same entity at t=2. It does not matter whether the changes are the result of human
intention or not: the application of a rule that declares the existence of new entities whenever existing
entities achieve a defined status permits us to replicate, in a computer model, the characteristics that
we see in real‐world emergent transactions: they are novel; they are sudden; and they are not
predictable by an understanding of their causes.
Conclusion
We may speculate, like Sellars, that emergence occurs because "at specific degrees of complexity of
organization, new properties are formed in order to establish a fresh and simpler point of departure"

commutative: a+b = b+a
associative: (a+b)+c = a + (b+c)
monotonic: if a < b, then (a+x) < (b+x)

Quantities of entities and properties of entities are not necessarily additive and
subtractive simpliciter; most transactions in the real world are:
non‐commutative: a+b b+a
non‐associative: (a+b)+c a + (b+c)
non‐monotonic: if a < b, then (a+x) >, =, or < (b+x)
non‐reversible: if c = a+b, then c‐a b

1 + 1 = ???
Which are a Special (Limited) Case of the Assumptions for Resultant Transactions

Summary
We currently create "Numbers‐Plus" by:
adding dimensions to represent qualities
adding extra operational procedures to represent special handling rules
But we must also:
explicitly add environmental conditions ("factors") onto the operations
add other "considerations" besides UM that affect how a rule is to be executed.
This will permit us to better represent known facts about:
emergent behavior (i.e. properties of sum not predictable from properties of
summands)
nonlinear behavior (i.e. quantity of sum not predictable from quantities of
summands; output not commensurate with input)
