Part 1. How Philosophy Began
1.1 From Mythos to Logos
In all ages of recorded history, human beings around the world have asked fundamental questions. Why are we here? Why does the universe exist? What is truth? How do we distinguish knowledge from opinion, reality from illusion, right from wrong? What is justice? Universal questions like these are fundamental in the sense that the answers we give to many other questions depend on the answers we have already given to these. The “fundamental questions of life,” as they are sometimes called, are important because the answers we give form the foundation of our worldview—our general understanding of the universe and our role within it. And whether we realize it or not, the choices we make in life all reflect, to one degree or another, our worldview.
At the beginning of the sixth century BC, most people around the world turned to their society’s myths (from the Greek root mythos) for answers to the fundamental questions of life. The ancient myths presented authoritative answers in the form of colorful, easily memorized stories that could be handed down orally from generation to generation. Here are three, from ancient Egypt, China, and Africa, respectively.
· A god named Khnemu, depicted as a man with a ram’s head, built an egg. When the egg hatched, the sun popped out. Khnemu then “sculpted the first man on a potter’s wheel.” This is the origin of man.[endnoteRef:2] [2: . “Khnemu (Khnum),” Ancient Egypt: The Mythology, last updated April 11, 2017, http://www.egyptianmyths.net/khnemu.htm.]
· In the beginning “there was darkness everywhere, and Chaos ruled. Within the darkness there formed an egg, and inside the egg the giant Pangu came into being. For aeons, safely inside the egg, Pangu slept and grew. When he had grown to a gigantic size he stretched out his huge limbs and broke the egg. The lighter parts of the egg floated upwards to form the heavens and the denser parts sank downwards, to become the earth. And so was formed earth and sky, Yin and Yang.”[endnoteRef:3] [3: . “Chinese Myths: Pangu and the Creation of the World,” Living Myths, last updated April 12, 2016, http://www.livingmyths.com/Chinese.htm.]
· In the beginning there was only darkness, water, and the great god Bumba. One day Bumba, in pain from a stomach ache, vomited up the sun. The sun dried up some of the water, leaving land. Still in pain, Bumba vomited up the moon, the stars, and then some animals: the leopard, the crocodile, the turtle, and, finally, some men. This is the origin of man.[endnoteRef:4] [4: . “African Creation Myths,” last modified Jul.

Mythbusting: Are Science and Religion Really at War?Maya Bohnhoff
An exploration of common myths surrounding the historical relationship between science an religion. From a Baha'i perspective, though the information is largely from Ronald Numbers's anthology on the subject of science and religion: Galileo Goes to Jail.
This article describes a new way to calculate binomial confidence limits, ones that define an interval that is narrower than the limits calculated by the Score, Wald, or Exact methods, and that is more defensible from a theoretical point of view since, unlike other binomial confidence limits, these Reasonable Limits are not statistically significantly different from the sample proportion on which they are based.
Teaching the meaning of the correlation coefficient is difficult enough without having to use a confusing formula for it. This "introduces" a "new" equation whose very form helps explain the meaning of the correlation coefficient.

4. Introduction
• As seen in the preceding headlines and cartoons, we grow up these days
bombarded by the use of statistics and probability.
• In spite of this, new students to the subject dread taking it:
• Students have a “natural psychological reaction unfavorable to the study of
statistics.”
– (introductory statistics textbook, 1934)
• "Statistics implies, for most students, a new way of thinking ⎯ thinking in
terms of uncertainties or improbabilities....When confronted with statistics
for the first time, some may find a mental hurdle which can be emotionally
upsetting."
– (introductory statistics textbook, 1960)
• The reasons for such reactions may lie buried in mankind’s own story of
discovering the subject.

5. Philosophical Probability thru the End of the
Renaissance
Probability and Chance in Ancient Greece
• In ancient times, probability was a concept without any mathematical
connotation.
• In ancient Greece, even tho the equivalent of our word “chance” was used, it
referred only to unexpected events caused by meddling deities.
• Likewise, the word “probability” was used, but only to refer to an intuitively
sensed degree of uncertainty about future events, events that could be predicted
only by learning what the Gods planned to do next.
• Socrates suggested that life’s unexpected events might not be due not to deities
but rather due to other causes which are simply unknown to us. For this, he was
condemned to death — his crime was that he “denied the reality of the gods and
corrupted the youth of Athens.”
• Plato wrote that arguments derived from probabilities are “impostors and ... apt
to be deceptive.”
• Aristotle wrote: “that which is probable is that which happens generally.” A
modern historian has written that “Aristotle was the first to attempt an
explanation of chance….[he stated that] chance is opposed to mind and reason
and its cause cannot be determined.”
• An important comment (to be recalled later in this seminar) is that Hippocrates,
the “Father of Medicine” and contemporary of Socrates, wrote that
experimentation, in our sense of the word, was “futile” because the Gods
controlled the outcome of any experiment. His approach to science was to
collect what information existed, and to philosophize about it.

6. Medieval Rules of Evidence
• The classical, theo-centric view of probability and chance and its anti-science
stance was almost universally held until the Middle Ages.
• One notable exception was Roger Bacon, who today is sometimes called
the “Founder of Science”, but who in his day had little impact on the
beliefs of society at large. Even tho he preached the value of
experimentation, he did not depart significantly from the Aristotelian
philosophical approach that still dominated all aspects of thought:
“… the Medieval [scientific] philosopher [including Roger Bacon]
fitted the results on his experiments into a theory already firm in his
mind [the theory having been obtained from Aristotle, the Church, or
other authoritative sources]. He knew what “light” was before
making experiments on refraction; he knew the cosmological
significance of “weight” before attempting to determine the speeds at
which heavy bodies fall.” (a modern historian)
• At last, the first substantive change in philosophy came in the area of civil
justice. In 1215, the Church outlawed torture in civil matters, torture sometimes
being the way the courts asked for God’s input on the guilt or innocence of the
accused (e.g., if the accused drowns when forcibly submerged, then he must
have been guilty, otherwise God would have saved him). The alternative chosen
was a system called the Roman-Canon Theory of Proof.
• In that system, evidence was assigned a fractional numerical value. At the end of
a criminal proceeding, the judge added up the numbers — he literally added up
the evidence, as we still say today — and guilt or innocence was proven by the
magnitude of the sum. This procedure was called the “arithmetic of proof.” In a
sense, it was incipient mathematical probability, that is, the higher the number
the greater the probability.
• Later in the 13th century, the preeminent theologian Thomas Aquinas
constructed a philosophical basis for the “arithmetic of proof.” He built his view
upon probability’s classical definition: the Greek word for probability meant
literally “resting on opinion” and the Latin equivalent meant “worthy of
approbation.” Aquinas wrote that evidence was probably true if it were based on
authoritative opinion — the more authoritative the source, the more probable its
truth.

7. Mid-Renaissance Natural Philosophy
• Omens have always been both fascinating and terrifying, because they have
been viewed as “signs” (i.e. messages) from God. An authoritative opinion
about an omen would have a large numerical value in the “arithmetic of proof.”
• Similarly, tarot cards, tea leaves, and especially the outcome of a roll of 3 dice
were considered controlled by God, and so therefore were signs from God,
which could be interpreted if one knew how to read the signs (that is, read the
tea leaves etc.)
• In the 1500’s, nature’s everyday appearance came to be recognized as much as
“signs” from God as omens or tarot cards. This recognition was an outgrowth of
a new philosophy called the Doctrine of Signatures that came to be accepted in
a relatively short period of time as the norm in all walks of life, as the result of
proselytizing by a well-known German physician named Paracelsus.
• The Doctrine of Signatures stated that Nature is the highest, most
authoritative, most “probable” of all testimony. Accordingly, Nature is
not just a work of God but his actual word, which is readily decipherable
by those who know how to “read” the words, or rather “read the signs.”
• The Doctrine of Signatures helped mankind begin to realize the
relative importance of internal evidence such as shape, weight, and
texture as compared to external evidence such as omens, books, and
opinion.

8. Late-Renaissance Natural Philosophy
• Francis Bacon was a lawyer who, in the early 1600’s, in the latter part of his life,
became famous as a natural philosopher because of his publications on the
experimental method, which came to be called the “Baconian Method.”
• Prior to Bacon, almost all scholarly opinion agreed with Hippocrates’
ancient claim that experimentation is futile. As a result of which, except
for the mechanical arts, “..in the early 17th century one knew for certain
little more than Aristotle had known” (according to a modern historian).
• No one had previously made experimentation a philosophical principle.
“That men should deliberately experiment -- as distinct from merely
observing nature [as stressed by the Doctrine of Signatures]-- had seldom
been advocated, certainly not with the systematic thoroughness which
Bacon proposed…. To Bacon, experiment was the one true necessary
ingredient of scientific endeavor…the one true way.”
-- This philosophical principle was expressed clearly and forcibly in
Francis Bacon’s writings in 1620, which were read by Blaise
Pascal’s father. According to one of Blaise Pascal’s biographers, his
father’s “enthusiasm had taken fire… [as a result of reading Bacon]
[and he became] a fervent believer in experimental science. No Jesuits
for him! No royal road to learning…a fig for the schools and their
traditions! The training that he gave his children [he home-schooled his
son, Blaise] was based upon physical notions [as well as religious
ones]…” Based upon such philosophy, Blaise Pascal was soon to
become the co-founder of mathematical probability.
• Possibly his greatest contribution was as a proponent of inductive logic.
“The method of induction was Bacon’s bid for a new logic to replace
Aristotle’s [method of deduction]….” It is important to note that the
approach taken to experimentation by Roger Bacon (the “Founder of
Science”), 3 centuries earlier, was thoroughly Aristotelian.
“…to doubt Aristotle on one issue [such as that the earth revolves around
the sun] was to doubt him on all, and consequently some problems of
the scientific revolution…implied the annihilation of extant learning”
and “the whole established body of natural philosophy”.

9. Gaming Odds before Mathematical Probability Was Understood
• The Doctrine of Signatures and the Baconian Method produced in some
Renaissance gamblers the belief that they or their mathematician friends could
somehow objectively calculate gaming odds and thus gain an advantage over
their less-experienced opponents. Aristotle’s implied claim that chance could
not be calculated was about to be proven wrong.
• The science of mathematical gaming odds might have developed earlier than the
late Renaissance had not Christian theologians since at least the 4th century
condemned gambling of all types. Justification for this ban was given by citing
Old Testament passages in which God’s will had been sought by choosing lots
⎯ Christians were taught that to seek God’s viewpoint in this way was more
than presumptuous, it was profane!
• A few early publications included attempts to quantitate chance and/or provide a
philosophy on which to base mathematical probability.
• In 1525, Gerolamo Cardano wrote a 15 page manual on the
rudimentary principles of gaming odds, entitled Book on Games of
Chance.
• In the early 1600s, Galileo published his own short pamphlet
entitled On Playing Dice, which explained most of the same ideas
as had Cardano.
• In 1619, a Puritan minister named Thomas Gataker, in his Of the
Nature and Use of Lots, echoing the writings of some renegade
ancient Grecian and Roman philosophers, explicitly proposed that
natural laws, rather than divine ones, determine who profits at
games of chance.
• What is also amazing about these writings of Cardano, Galileo, and
Gataker is that they appeared at a time when nearly everyone, except for
a few professional gamers and mathematicians, still believed that God or
a personified Fate controlled the outcome of gaming events. For example,
the throw of three dice was still commonly used to foretell the future — a
practice that was at that time over 2000 years old!

10. Mathematics & Statistics Thru The End Of The
Renaissance
Mathematics in Ancient Times
• The earliest known textbook on mathematics dates from Greece 2400 years ago,
at the time of Socrates
• After the Roman armies conquered the “world” two millennia ago,
mathematical study among the peoples of the Empire went into decline.
Supposedly, the obsessively practical ancient Romans were culturally
disinclined from theoretical mathematics — no less an ancient Roman luminary
than Cicero literally boasted that his countrymen valued mathematics only for
counting and measuring.
• However, some Roman figured out the odds of life expectancy, to the extent
that they were able to develop a reasonable chart of annuity cost based on age
of the applicant. This information was lost when Rome fell, and not
rediscovered for more than a millennium:
Many Renaissance municipalities and governments were funded in large
part by the selling of fixed-rate lifetime annuities — that is, and old and
young buyers paid the same price for a lifetime of the same annual
payout. Only in the late 1600s (after the discovery of the principles of
mathematical probability and Statistical science) did some governments
begin to put their annuity prices in line with mathematical probability
and actuary data,. But the English government waited another 100 years
to abandon fixed-rates, for fear of interfering with one of its primary
means of financing wars: “no British government before 1789 appears to
have made the cost of an annuity a function of the age of the purchaser”
• An Indian poet who lived in the early Christian era, seems to have been
the first person in the world to discover the principles of Statistical
science. The principles are included in the Story of Nala, in the great epic
poem Mahabarata. The story contains explanations and examples of
sampling and gaming odds; however, it appears that nobody but the
author understood that this was not science fiction, for no further
discussion can be found in any extant Indian texts.

11. Mathematics and Pre-Renaissance Church Teachings
• In the early Christian era, St. Augustine emphatically proclaimed that “the good
Christian should beware of mathematicians [because they] have made a
covenant with the devil to darken the spirit and to confine man in the bonds of
Hell.” What he meant was that mathematicians were invariably astrologers.
• The Roman Code of Mathematics and Evil Deeds condemned the art of
mathematics because of its astrological connection.
• In the early medieval era, the word “mathematics” actually meant
astrology, and teachers of astrology were called mathematicii.
Universities, all of which were run by the Church, took a theologically
conservative stance by teaching only arithmetic and geometry.
• “In no one of the civilizations that have contributed to our modern one
did mathematical learning exist on as low a level as it did in medieval
Europe. All in all, a learned European mathematician of a thousand years
ago knew far less than any elementary-school graduate does
today....From the years 500 to 1400 there was no mathematician of note
in the whole Christian world.” (Noted mid-20th century mathematics historian)
• In the late medieval era, after algebra was introduced and was deemed to
greatly improve on astrological calculations, the words physician and
“algebraist” came to be almost synonymous.

12. Mathematics during the Renaissance
• Laws were passed that mandated the exclusive use of Roman numerals, and
forbade the used of “Arabic” numerals, in commercial contracts and official
documents (e.g. in Florence as late as the year 1299). Although Arabic
numerals gradually became accepted in Italy in the early Renaissance, it wasn’t
until the late 1500s that they became the commercial standard in all of Europe.
• "The long and strenuous work of the most gifted minds was necessary to
provide us with simple and expressive notation which...enables even the less
gifted of us to reproduce the theorems which [previously] needed the greatest
genius to discover....Our notation is an instance of the great spirit of economy
which spares waste of labour"
• “The very concept of averaging is a new one, and before 1650 most people
could not observe an average because they did not take averages. Certainly a
gambler could notice that one strategy is, in Galileo’s words, ‘more
advantageous’ than another; but there is a gap between this and the quantitative
knowledge of mathematical expectation.”

13. The Birth of Mathematical Probability & Statistical
Science
The Birth of Mathematical Probability
• “By 1630, two generations of effort [to advance knowledge beyond that of the
ancients] had hardly seemed to be rewarded, and science appeared as much
unorganised as ever. Yet…all reached fruition in the next thirty years.” (noted
20th-century historian of the scientific Renaissance)
• In late 1654, Blaise Pascal, a celebrated mathematician and inventor, became
enthralled with solving a gambling problem that had stumped mathematicians
for over 150 years. By mail, he consulted other mathematicians, including
Pierre de Fermat, a lawyer and part-time mathematician. The letters that these
two sent to each other in the next few months, discussing how to solve the
problem, are generally considered to comprise the first real theory of
mathematical probability.
• During the late-Renaissance, the word “probable” was generally reserved
for assertions that were "not completely ...impossible" or had "an
appearance of truth" or were "midway between truth and error." By the
mid-1700s, after decades of mathematical treatment of probability by
mathematicians and gamblers who followed in the footsteps of Pascal
and Fermat, use of the word “probable” among the general public shifted
to the somewhat mathematical concept expressed by Kant as "more than
half certain."

14. The Birth of Statistical Science
• The science of Statistics was born as the result of a hobby indulged in by John
Graunt, a prosperous London shopkeeper and amateur collector of numerical
data. In 1662, apparently not yet aware of Pascal and Fermat’s achievement, he
published his Natural and Political Observations Made Upon the Bills of
Mortality. It contained practical applications of his independent discovery of the
basic concepts of statistical methods and sampling.
• His book was the first published account in the Western world where
inductive logic and a sample of data were used for what we call statistical
inferences.
• The first such statistical inference in Western history was
Graunt’s calculation of London’s population size.
• Another famous Graunt inference was that slightly more
males babies were born than females, year in, year out, in all
socio-economic and ethnic categories.
• The first abuse of statistics: What did this
male/female ratio mean?
• Statistical Science was known 300 years ago as “Political Arithmetic,” because
the information it generated was primarily used for decisions by the body
politic, i.e., the State; such information about the State came to be called
“Statistics” (from root German words that mean “relating to the State”). The
term Statistics completely supplanted the term Political Arithmetic in the 1800s.

15. Why Was/Is It So Difficult to
Discover/Learn/Understand Statistics & Probability?
• No one really knows (1975, by a well known historian of statistics and probability)
• “The mind all too readily tends to mould facts into the forms of prior
conceptions” (1896, from a textbook on “inductive logic”); and many of our prior
conceptions run contrary to a view of the world consistent with mathematical
probability and statistical science.
• For example, as a society, we still think much like people did millenia ago:
• “To say an event is determined by chance is to say we do not know how
it is determined” (1940, from a book designed to “popularize” mathematics).
• When an unexplainable event occurs (such as the remission of a serious
illness), many of us say that a miracle has occurred. After the bonfire
tragedy at Texas A&M University in 1999, which followed on the heals
of a tragic car accident on campus, one student was quoted in the national
press as saying that “I guess we’re just having a string of bad luck.”
• If the local baseball team hasn’t won in long time, we say “they’re due.”
• Almost all of us believe that it’s much less likely for the numbers 1, 2, 3,
4, 5, and 6 to be drawn in the lottery than other combinations.
• We still believe that certain people are lucky (“She always wins when she
goes to Reno”), or that we ourselves are “just not lucky.”

16. In Conclusion:
Probability and Statistical Science are new ways of thinking about our
physical world. Some paradigms held by our culture predispose us to have
great difficulty, or an impossibility, in comprehending this view.
• This subject will always be difficult for those with a fatalistic view of life.
• This subject will always be difficult for those to whom formal authority
(or a con-man) takes precedence over their own logic and observations.
• A Statistic’s teacher’s challenge is more about teaching new attitudes,
philosophy, and independent thought processes than about teaching
math.
