- Question What are mathematical objects and is
mathematics in a trap when it considers the
foundations of mathematical knowledge? Is
Mathematics Invented? - Biologists think they are biochemists,
Biochemists think they are Physical Chemists,
Physical Chemists think they are Physicists,
Physicists think they are Gods, And God
thinks he is a Mathematician. - (inference math is the ultimate truth.)
- Mathematics is made of 50 percent formulas, 50
percent proofs, and 50 percent imagination. - Philosophy is a game with objectives and no rules
whileMathematics is a game with rules and no
objectives.
5Alternative Views on Foundations of Mathematics
(FOM)
- Whats the Issue?
- Mathematical structure seem to mirror physical
theory and often points the way to further
advances in that theory and even to empirical
predictions. So by induction we believe that this
is not a coincidence but must reflect some larger
and deeper truth about both mathematics and
physics. - Math is the foundation for the physical sciences.
But what is maths foundation? - Foundations of mathematics is a term sometimes
used for certain fields of mathematics, such as
mathematical logic, axiomatic set theory, proof
theory, model theory, and recursion theory. - The search for foundations of mathematics is also
a central question of the philosophy of
mathematics On what ultimate basis can
mathematical statements be called true? - Mathematical truth is demanded to have a
rigidity, an absoluteness, that is tantamount to
Platonism - Platonist mathematical realism, seems exemplified
by Kurt Gödel, who explored the existence of a
world of mathematical objects independent of
humans - In this view the truths about these objects are
discovered by humans. - In this view, the laws of nature and the laws of
mathematics have a similar status, and maths
effectiveness ceases to be unreasonable. - Not our axioms, but the very real world of
mathematical objects forms the foundation. The
obvious question, then, is how do we access this
world? - Alternate View
- The foundations of mathematics is, at least
partly, a scientific study of mathematical
practice. - In this view what mathematicians actually do and
actually say is of direct interest to the
foundations of mathematics. We are Trapped into
Believing otherwise.

Knowledge and the Manner in Which it is Acquired - The Decisive Influence of Language Use on the
Conduct of Mathematical Research
7The Process of Entrapment
- Since the late 19th century mathematicians with
the help of logicians have been digging
themselves deeply into a trap, but it is not
perceived as that. - The trap is built from certain structures of
logic and language reflecting beliefs and
habits of thought. - Assumptions that are treated as givens/reality -
reifications. - Theres a role for proper scientific inquiry to
help us out of a closer system, but most
mathematicians arent asking the questions - We need to step out of the trap to see it.
8The Concept of an Act of Acceptance as Such
Acts in the Doman of Language Use
- To accept something (experience or object) as
such is to take it for what it appears (or is
purported to be), and proceeding on that basis. - In science we should explore the consequences of
such assumptions. We should not easily
accept/reify something that is an assumption. - But in math the structures are built by ACTS
which are accepted because they establish new
theorems they become objects to manipulate. - Suppose we find a problem with accepting a
conclusion. Only then do we check the proof. - But maybe what happened with Euclids 5th axiom
(suppose IT is not TRUE) is more broadly
applicable and this supposition testing should be
the approach. - Conclusion adopt an activist policy concerning
the invention and following of procedures that
entail the undoing of accepted belief and the
habits of thought. - A particular problem concerns language habits
- that make us accept some statements.
9Story of a Definition that was too good to be
true - PI
- We LEARN the DEFINITION but Its NOT obvious that
the ratio of large small circles will have the
same C/D ratio - Proof should PRECEED definition in a well founded
theory! - Otherwise we have just knowledge of definitions
- We are victims of an education that teaches
definitions w/o proof or checks - Result is that our reasoning seems objective but
is really standpoint oriented.
10Belief Systems Attitudes about Undoing Accepted
Belief
- We fall into traps from certain habits that
include acceptance - A natural motivation to have a world view
- But we can fall into the sin of certainty
(Maturana) a belief system - Therefore we need a method that doesnt yield to
such habits of acceptance and untested belief
thats scientific. - If we accept a belief into our system, which
then doesnt allow that belief to be challenged,
then we are trapped. - We might have been trapped by a formalist
approach. - To a Formalist, like Hilbert, mathematical
theorems can be formulated as theorems of set
theory. - The truth of a mathematical statement, in this
view, is then nothing but the claim that the
statement can be derived from the axioms of set
theory using the rules of formal logic. - But in pure math the only criteria is consistency
the consistency of the system itself. This may
trap us in a System of thinking. - As a counter we need adequate acceptance
criteria.
11Descriptive Fallacies Produced by a Failure to
Respect Considerations of Standpoint
- Examples of Beliefs
- The sun is largely made of hydrogen
- Every mathematical statement is either T or F.
- Is this true or false?
- Does everyone see it this way? No we can have
deviant logics modal, - many-valued, dialethic, intuitionist, fuzzy etc.
- In 1951 Quines Two Dogmas Of Empiricism
challenged received notions of knowledge, meaning
and truth. - He arguing that logic and maths, like factual
statements, are open to revision in the light of
experience. - Experience, says Quine, does not confirm or
falsify individual statements, but instead
confronts an interlocking theory-laden system of
statements, which has to be adjusted as a whole. - And there cannot be any universally-held system
of beliefs, he argued in his major work Word And
Object (1960), since the way any theory describes
the world is relative to that theory's linguistic
background webs of belief. - We use other criteria like simplicity and beauty
when comparing systems and our logic SEEMS BETTER
than the deviant ones when considering these. - But even Quine found it difficult to break out of
our classical logic system. - Hes still an insider looking at the deviant
outside from insider - criteria.
12The Case of Pure Mathematics Contemporary
Mathematicians Attachment to His Belief
- Mathematicians are trapped by their shared math
experiences (reality) in terms of math objects
belonging to a set. - This is learned and is seductively simpler than
the deviant approaches, such as not accepted the
law of excluded middle in the form that for any
real numbers a, b, either a b or a ? b. - The failure of these seemingly unquestionable
principles in turn vitiates the proofs of a
number of basic results of classical analysis. - Most mathematicians consider the language of set
theory foundational, simpler and more intuitive
than that of lambda calculus (or the related
category theory). So why switch? - BUT we might reconsider if we ask, how does
accepting the law of excluded middle contributes
to the construction of what we call mathematical
reality?
13A View from the Edge of the System The Tug of
Language that Pulls one Inside - Intuitionist
Logic
- Looking from the edge we have a better chance of
freeing ourselves from being too inside a system.
We can contrast inside and outside views by
considering Goldbach's Conjecture, that all even
numbers larger than 4 is the sum of two primes
18 13 5, or 102 97 5. - At the edge or our understanding taking an inside
stance (realist perspective) it makes sense to
suppose that this conjecture might be true
because every one of the infinite series of even
numbers exists as a sum or two primes, even
though there might be NO proof to be discovered. - To a realist the answer already exists, but is
unknown to us, its real, a thingthat we
discover. - Our author GS follows Mike Dummetts approach
(anti-realism). To understand this assertion
means being capable of recognizing what would
count as evidence for or against it. - Evidence is based on a procedure.
- As far as the intuitionist/anti-realist is
concerned, the only thing that COULD make the
conjecture TRUE is that there be a proof, a
procedure to establish it. We construct it.
Before that it is indeterminate. - For all we know, according to the intuitionist,
there might be NO PROOF and no counter-example,
in which case there is nothing to give the
conjecture a truth-value. - The belief that every proposition is
determinately true or false is - the principle of bivalence. Its an assumption.
- Dont accept that knowing an answer means
something EXISTS
14On Not Being Taken in by Language and Statements
to Signals Using Language to Make Knowledge
Sharable
- Indeterminacy seems distasteful especially when
each step we think of is determinant. - Why this reaction to the idea that an answer may
not exist before a procedure was carried out? GS
proceeds as follows- - Is it the Platonic conceptual habits of language?
Discovery not Creation of answers" in
statements. Answers need not be things. - Consider that the role of language is to make
knowledge sharable (Sq root of 2 is not a
rational ) - We must already share an understanding of how
language is used to share this new info. - When we establish this initial understanding we
may limit other understandings. - Thus a statement in nothing more than a signal
of being in possession of some piece of
knowledge. - To inquire about a statements veracity is
independent of our knowing it. Statements arent
things they are only acts of stating.

15Two mathematical Statements a Procedure for
Getting into Position to Make at Least One of Them
- An invented example (you can invent your own)
- The author, GS, considers the fractional part of
the sequence (3/2)n and - discusses an assertion on where they fall as n
goes from 1 to 2,000,000. - We can assert (S) that more than 1 million fall
in the interval 0-1/2. - Or we can assert (T) that more than 1 million
fall in the interval interval ½ to 1. - It seems clear why one or the other will be true
procedurally. - So is it discovery or creation? GS argues that
it is better captured by a metaphor/sign of
creation and not discovery.
16Understanding Mathematical Statements One Way
of Making Mathematical Language Work
- If you ask a philosopher what the main problems
are in the philosophy of mathematics, then the
following 2 are likely to come up - what is the status of mathematical truth, and
what is the nature of mathematical objects? That
is, what gives mathematical statements their aura
of infallibility, and - what on earth are these statements about?
- W. T. Gowers, Does mathematics need a
philosophy?, presented at Cambridge University
Society for the Philosophy of Mathematics 2002 - Heres the confusion. The statements more than
a million terms of the sequence", and
fractional part etc. all are in present tense
and thus seem to say that the terms already
exist. - Present tense is oriented to the world of
objects. - But all that is in the present tense is our
signaling that we understand, which is a
convention established in our language. - And if we accept this view, then perhaps lack of
existence is also true when we talk about
number sets functions. - As scientists we should not be uncritically using
language like this - In GSs view mathematical language should signal
mathematical knowledge involves conventions
that govern the use of mathematical language. - Conventions are established by usto a purpose
such as K or acts of strict counting and
performing computation. - E.g. conventions on what ABC mean for 57 and
AB etc. - The present tense in these is purely
metaphorical. - It means if I want to be in the state of
knowing I have a procedure/computation to arrive
at something that witnesses the validity of the
assertion.
17The Contemporary Mathematicians Unfulfilled
Task Making Mathematical Language function the
Way He Wants it To
- Using a constructive method as convention, math
proofs would be of genuine scientific use in the
traditional sense the proofs do say something
about acquiring knowledge. - But the Contemporary Mathematician prefers to say
that 347 is not about acts of counting but
about the relation of numbers. - Our author claims that we dont have proper
conventions to really support this. - What sort of thing is a set? We have
intuitions but structures to model these seem
insufficient to outsiders. - Better to talk about operational interpretations
of sets.
18A Pseudomystery about the nature of Mathematical
Knowledge and the Manner in Which it is Acquired
- Here we enter the faculty of mind issue which
is a Pseudomystery, since the Mathematician cant
explain Mathematical Knowledge and how it is
Acquired. - Mathematicians conclude that it tells us about
limits of our mind. - Both S and its negation are unprovable,
- The First Incompleteness Theorem
- What Gödel points out is that if a formal logical
system contains a statement S, "This statement is
unprovable" which can be proven true, then we
have a contradiction. - Because the statement is provable, despite claims
to the contrary. - On the other hand, if the statement is false,
then the theory is incompleteit contains a
statement which is not able to be proved. - This means no formal logical system can be both
consistent and complete. - But this may tell us nothing really interesting
about the mind only the incorrect assumptions
about mathematical objects. - Consider
- A great truth is a statement whose opposite is
also a great truth. Niels Bohr - We have to do mathematics using the brain which
evolved 100,000 years ago for survival in the
African savannah. Stanislav Dehaene
19The Decisive Influence of Language Use on the
Conduct of Mathematical Research The Influence
of Talk About Statements Being True
- Does this understanding of language problems etc.
lead to a mathematics that is useful and a method
that is practical in daily work? - Yes we can reformulate mathematical statements to
eliminate talk about mathematical objects. - If, for each X, either statement A(x) or B(x) is
true then either all statements A(x) are true or
some statement B(x) is true. - What is present tense is the statement and not an
object referenced by the statement. - As for everything else, so for a mathematical
theory - beauty can be perceived but not explained.
Arthur Cayley
20Concluding Remarks - The Title Question Answered
- In mathematics how do we attain knowledge of
object independent of us? Maybe
we dont. - Its more an Illusion, produced by acceptance of
beliefs that is encouraged by language habits
than a special mental faculty. - Its not knowledge acquired in a special way, it
is subject to scientific criteria, its
empirical. - Numbers are tools, not rules.
- Numbers are symbols for things the number and
the thing are not the same. - Skill in manipulating numbers is a talent, not
evidence of divine guidance. - The product of an arithmetical computation is the
answer to an equation it is not the solution to
a problem. - Arithmetical proofs of theorems that do not have
arithmetical bases prove nothing.

24More on Hilberts Influence
- German mathematician who reduced geometry to a
series of axioms and contributed substantially to
the establishment of Formalism in foundations of
mathematics. - His work in 1909 on integral equations led to
20th-century research in functional analysis his
Formalism, which treats mathematics as a series
of symbols which can be rearranged according to
various formal rules, sheds no light on the
obvious relevance of mathematics to natural
science, but led to the development of
meta-mathematics, the systematic study of the
comparative structures of mathematical theories,
which was essential to subsequent elucidation of
the problems of the foundations of mathematics by
Gödel and others. - Hilbert completed his PhD at the University of
Königsberg in 1884, remaining there till 1895,
after which he was appointed Professor of
Mathematics at the University of Göttingen, where
he remained for the rest of his life. - Hilbert introduced a highly original approach to
the consideration of mathematical invariants
which allowed the structure of mathematical
theories to be themselves the subject of
mathematical analysis in a way hither to
unimagined. - An invariant is that aspect of something which
remains the same when a corresponding
transformation is applied to something. - The meaning of invariant is most easily
understood in terms of geometrical
transformations such as displacement (where shape
and size are invariant) or dilation (where shape
but not size are invariant). - Hilbert proved that all invariants can be
expressed in terms of a finite number. His new
method allowed him to produce a set of axioms for
Euclidean geometry which marked a turning point
in the theory of axioms.
25Foundations for Classical Logic
Classical logic rests upon 3 axioms. These axioms
are held to be 'self evident'because all
syllogisms rely on them, and because they can be
defended through retortion. "Retortion" means
that any syllogism used to refute these axioms
will have to rely on them (!!!!!) - leading to a
self refutation (we call this type of self
refutation the "Stolen concept fallacy"). You
can see why GS talks about being trapped in a
system!!!

The map is not the territory, and the name is

He was part of the Cybernetics era. The
anthropologists Gregory Bateson and Margaret Mead
contrasted first and second-order Cybernetics in
the diagram on the right (1973). It emphasizes
the requirement for a possibly constructivist
participant observer in the second order case as
shown in their figure.
Second-order cybernetics was created from the
attempts of classical cyberneticians to construct
a model of the mind. Researchers realized
that . . . a brain is required to write a theory
of a brain. From this follows that a theory of
the brain, that has any aspirations for
completeness, has to account for the writing of
this theory. And even more fascinating, the
writer of this theory has to account for her or
himself. Translated into the domain of
cybernetics the cybernetician, by entering his
own domain, has to account for his or her own
activity. Cybernetics then becomes cybernetics of
cybernetics, or second-order cybernetics. Heinz

28Other Critiques of mathematical Foundations
- Karl Popper believed that mathematics was not
experimentally falsifiable and thus NOT a
science. - However, other philosophers, e.g. Imre Lakatos,
have applied a version of falsificationism to
mathematics itself. - An alternative view is that certain scientific
fields (such as theoretical physics) are
mathematics with axioms that are intended to
correspond to reality. - The theoretical physicist, J. M. Ziman, proposed
that scienctific knowledge is public knowledge
and thus includes mathematics.? - What mathematics seems to share with many of the
physical sciences is the exploration of the
logical consequences of assumptions. - Intuition and experimentation also play a role
in the formulation of conjectures needed grow
both mathematics and the (other) sciences. - Experimental mathematics continues to grow in
importance within mathematics, and computation
and simulation are playing an increasing role in
both the sciences and mathematics, weakening the
objection that mathematics does not utilize the
scientific method. - In his 2002 book A New Kind of Science, Stephen
Wolfram argues for a new kind of computational
mathematics deserves to be explored empirically
as a scientific field in its own right. Maybe it
is the real math.
