Philosophies of Life
Ontology = Philosophy that deals with meaning of existence
Stoics (after Zeno of Citium) seek tranquility of mind, and
thereby happiness, as their way of life
Cynics (after Greek philosopher Antisthenes) believe in
renunciation of material possessions and living like a hermit as
their way
Epicureans (after Greek philosopher Epicurus) embrace
material wealth, fame and fortune
Hedonists seek pleasure- all forms of it- as their ultimate goal.

Think of the endless cruelties visited by
the inhabitants of one corner of this
pixel on the scarcely distinguishable
inhabitants of some other corner. How
frequent their misunderstandings, how
eager they are to kill one another, how
fervent their hatreds. Our posturings,
our imagined self-importance, the
delusion that we have some privileged
position in the universe, are challenged
by this point of pale light. -Carl Sagan

Vs.
Post-Copernicanism
Heliocentrism
Felix Bast
9.
Nicholas Coppernicusfalsified Ptolemaic geocentrism by scientific
methodology and put forth theory of heliocentrism
Heliocentrism was originally put forth by Aristarchus in 280 BCE
but not supported by Greek authorities
The heliocentric theory was successfully revived nearly 1800 years
later by Copernicus, after which Johannes Kepler described
planetary motions with greater accuracy, with Kepler's laws, and
Isaac Newton gave a theoretical explanation based on laws of
gravitational attraction and dynamics.

Scientific Methodology
Logical,rational, systematic, reproducible, empirical, and
evidence-based methodology to test a hypothesis in question
The scientific methodology involves observations,
experiments and statistical hypothesis testing
Proving or disproving, a principle called “Falsifiability” of Karl Popper
the famous British Philosopher of Science
Developed with Francis Bacon’s Novum Organum published in 1620
Felix Bast

Pseudoscience
has noneof the elements of scholarly scientific methodology;
instead of logic and reason it tries to appeal through emotion such
as mysteries and miracles, and irrational anecdotal records.
Examples:
UFOlogy (Unidentified Flying Objects as aliens), BermudaTriangle,The
Bigfoot, Alchemy, Polygraph
Alternate medical practices: Ayurveda,Yunani, Siddha, Homeopathy,
Telepathy, Reiki, and Acupuncture
Astrology and other predictive systems of divination such as ESP (Extra
Sensory Perception), Clairvoyance, Illuminati, and predictions of
Nostradamus
Hoaxes, Conspiracy theories, Supernatural concepts etc.

Origin of ReligiousThought
‘Making sense of world’; ‘life events have a deeper meaning’,
‘things happen for a reason’; ‘living and non-living things are
there for a purpose’ >> anthropocentrism
Religion is based, I think, primarily and mainly upon fear. It is partly the
terror of the unknown and partly, as I have said, the wish to feel that
you have a kind of elder brother who will stand by you in all your
troubles and disputes. [...] A good world needs knowledge, kindliness,
and courage; it does not need a regretful hankering after the past or a
fettering of the free intelligence by the words uttered long ago by
ignorant men.
—Bertrand Russell
Felix Bast
13.
Geocentrism Vs. Anthropocentrism
Earth is the centre of universe
Rationale:
You live in this planet and this is
your “world”, universe surrounds
you
Human being is the centre of universe
Rationale:
You are a human being, and you
deserve a privileged position among
other living beings
Confirmation Bias, a Cognitive Bias
Felix Bast
14.
Humanties Vs. Science
Study of human culture
History
Languages
Law
Literature
Performing Arts
Philosophy
Psychology
Religion
Methodology is mostly critical or
speculative
Pseudo-humanity
History denialism (E.g. Holocaust
denials)Vs. Historical Revisionism
Anthropocentric perspective
“there is nothing either good or bad, but thinking makes it so”
–Shakespeare (Hamlet)
Felix Bast

“Applied” Sciences too
Medicine
Pharmacology
Agriculture
Aquaculture
Engineering
Biotechnology
All suffer a fallacy called
Anthropocentrism, or its
glorified synonyms,
“humanitarianism” and
“philanthropy”
Felix Bast
16.
Creation Myth
Theearth is only 6000 years old.
17th CEVC of Cambridge University, John Lightfoot “precisely”
calculated age of earth be 6019 years!
Entire life on earth created as it is by the god
God made the world for us
Earth, as well as its life, is “static” (not moving/evolving)
Felix Bast
17.
Brief Diversion: Hinduism
According toVedas age of earth is 1.97 billion years (precisely
197,29,49,116 years, in year 2015)
Vedas regarded that cosmos is eternal, recurring and cyclic,
which is strikingly close to the current scientific understanding
that the earth underwent cycles of warming and ice ages.
Pralayas and Mahapralayas as Extinction events
Dashawatara = Matsya (Fish)-Kurma (Tortoise)-Varaha (Boar)-
Narasimha (man-lion)-Vamana (dwarf man)-Parashurama

Felix Bast
18.
Theory of evolution
That haughty self-importance and elusive privileged position of
humanity were completely torn apart with Charles Darwin’s theory
of evolution through natural selection, first published in 1859.
Human beings, as we know them, developed from earlier species
of animals
We are evolved from apes and that the entire life on earth are
interconnected in a giant tree of life fashion with a common
ancestor for the entire living organisms that appeared only once in
the origin of life, the so-called principle of common descent.
Felix Bast
19.
Theory of Evolution
Entire life on earth are related
and can be drawn on “tree of
life”
By Natural Selection
Nature selects best-fit individuals
of a population that are well-
adapted
Felix Bast
Voyage of theHMS Beagle
Darwin was a great natural historian who read humanity papers too
(Thomas Robert Malthus’ papers on Economics and demographics)
And an explorer, he circumnavigated earth in HMS Beagle
He was to spend the next 27 years developing a theory to explain what he
observed.
Felix Bast
22.
Darwin’s theory ofDescent with
modification
Species that diverge
from a common
ancestor were at first
very similar (B & C are
more similar than either
with A)
Descent with
modification is how
new species are formed
Felix Bast
• Common descent: Entire life originated from
one individual (marked 1 in tree)
23.
Darwin’s Principal Observations
Observation 1: Overproduction:
Populations of all species have ability
to produce more offspring than the
environment can possibly support
with food, space and other resources.
This makes struggle for existence
inevitable: Inspiration from Malthus’
essay on population explosion
Observation 2: IndividualVariation:
Individuals in a population vary in
many heritable traits Felix Bast
24.
Darwin’s inference:
variational theoryof evolution
Over Production Individual variation
Differential reproductive success
Individuals with traits best suited to the
local environment (adaptations) thrives
(Natural Selection)

Goal/Purpose of life?
After becoming parent
Support kids till they find mate,
have sex, and make more
babies!
Direct reproduction
If could not find a mate (too
recalcitrant!), or could not make
a kid, try support your cousins
(Inclusive Fitness)
Indirect reproduction
Survive to find a mate, have sex, make babies
(transfer your genes to them)
Felix Bast
27.
Inclusive Fitness
Givesloud alarm call when attacked by a
predator to warn its local group
By emitting the alarm, it gives its own
location away, putting itself in more
danger, altruistic behaviour
Protecting other squirrels in the immediate
area will lead to the passing on of more of
the squirrel’s own genes than the squirrel
could leave by reproducing on its own
-Indirect reproduction
Felix Bast
Evolution in Action
Kettlewell’s Moths: England’s industrial revolution killed
tree lichen and added soot to trees, allowing the
population of peppered moths to shift in favor of the black
variety (previously rare mutation)
Felix Bast
Evolutionary Arms Race
Evolution selects fastest running predators (e.g. cheetah) and
preys (e.g. deer) however, within the limits dictated by the
economy of speed with lean and long limbs, versus probability of
having a fractured limb if it is too lean and long
Or, increasing height of trees to outcompete its neighbors for
maximum light harvest is within the limits set by the economy
of higher photosynthesis if tall, verses need to invest more
resources towards building stronger lignified vasculature for
water transportation.

Evidences of Evolution
•Fossil Evidence & Biogeography
• Homologous & Analogous Structures, Atavism
• Hip-bone in whales!
• Vestigial Structures
• Human tail bone &Vermiform appendix, Dolphin Hip bone
• Embryology
• “Ontogeny recapitulates phylogeny”
• Molecular Comparisons: Molecular Phylogenetics

Quiz
Penicillin isan antibiotic (anti-bacterial chemical produced by
a living organism) serendipitously discovered by Alexander
Fleming in 1928
After some 10 years, penicillin-resistant microbes were
reported from around the world; now most of the pathogenic
bacteria are resistant to original penicillin formulation
Which among the following is true regarding penicillin
resistant bacteria?
A. They existed before the invention of penicillin
B. They evolved after the invention of penicillin
Other analogous e.g.:
• Liquidator: Mosquito
• Trap: Rats
• Insecticide/herbicide
resistance
Felix Bast
40.
Answer A!
Theyexisted before the invention of penicillin
Variations are spontaneous, caused by mutations in DNA,
which is not directed by environment.
All nature does is to “Select” the best-fit variation
Salvadore Luria and Max Delbruck (ca. 1943)
Demonstrated spontaneous gene mutations in bacteria (not directed by
the environment).
Mutations arise in the absence of selection
Felix Bast
41.
Fluctuation Test (1943)
(A)If mutations
are induced by
the media,
roughly the
same number of
mutants are
expected to
appear on each
plate.
Should follow
Poisson
Distribution with
Mean=Variance
(B) If mutations
arise spontaneously
during cell divisions
prior to plating,
each plate will have
a highly variable
number of mutants.
Variance was much
greater than mean,
did not follow
Poisson. Non-
Random
Felix Bast
42.
Philosophical issues postDarwinism
StaticVs. Dynamic
Is static, ceaseless universe made by god (Plato’s Essentialism), or
‘change’ or dynamicity the natural order? Supersonic you.
PurposeVs Function
Before Darwin, philosophers asked ‘why’ questions citing the purpose:
possible purpose that god could have had in creating them.
Darwin found random, purposeless variation acted on blind, random,
purposeless natural selection answer to various “why?”
Evolutionary biologists of today seek “function” of pink color of
magnolia flower, not its purpose.Astronomers do not seek purpose of
comets or supernovas; chemists do not seek purpose of H2 bonds
Felix Bast
43.
Mediocrity principle
Darwin’stheory of evolution through natural selection paved
way for revolutionary mediocrity principle (against
anthropocentrism)
Nothing very unusual about the evolution of the Solar System,
the Earth, humans, or any one nation
Felix Bast
44.
Theology
Pre-Copernicanism (earthcentred universe) and human as top
of evolutionary ladder
Vs. Copernicanism and Darwinism (human are merely an
animal, no special position and no ladder of evolution)
Our great grandfathers were apes (not god)
Felix Bast
45.
Argumentum ad consequentiam
“Teach the children that they are animals; they will behave like
animals”
X is true (or false) because how much I like (or dislike) its
consequences
Even if teaching evolution encourage immorality, that does
would not imply that evolution was false.

Conflict between Humanitiesand
Sciences
AnthropocentrismVs. Mediocrity principle
Ethics and Morality in light of mediocrity
Racism
Altruism
Sexuality
Felix Bast
47.
Eusociality: Racism!
Lookingat community of ants; wherein worker ants act like slaves
and do not contribute in perpetuation of gene (which Queens do),
isn’t it seems like a natural law to consider racism and slavery (in
human society!?)
Eugenics
Felix Bast

Trolly problem (PhilippaFoot, 1967)
a trolley is hurtling down a track towards five people.You are
on a bridge under which it will pass, and you can stop it by
dropping a heavy weight in front of it. As it happens, there is a
very fat person next to you – your only way to stop the trolley
is to push the person over the bridge and onto the track,
killing the person to save five. Should you proceed?
What if this person if your Son? Daughter? Father? Mother?
Altruism is seen in a number of animals too!
Ponder on AltruismVs.Terrorism!
Felix Bast
Sexual cannibalism/ Altruism
Spider/praying mantis male gets eaten upon copulation by
females…sole purpose of its life was to copulate and
transmit own genes down the generation…how about
ours? Aren't our genes selfish?

Promiscuity isnatural order for majority of animals. It is a
social taboo for most of the countries, while prostitution is
legalized in many.
Age of consent =12 at Angola and 22 in Bahrain
Orgy normal for Bonobos and Chimpanzees, even for
uncontacted tribes of human beings, for conflict resolution
Violent gang rape is the natural order for ducks, dolphins and
spiders
Mediocrity principle doesn’t go very well with the morality,
ethics and human value system
Felix Bast
53.
Exaptation Vs ExtendedPhenotype
Exaptation/Co-option: Shift in the function of trait
E.g. Feather
Extended Phenotype: Phenotype should not be limited to
biological processes such as protein biosynthesis or tissue growth,
but extended to include all effects that a gene has on its
environment, inside or outside of the body of the individual
organism.
E.g. Bird Nest, Beaver’s Dam
An animal's behaviour tends to maximize the survival of the genes
"for" that behaviour, whether or not those genes happen to be in
the body of the particular animal performing it
Felix Bast
54.
Spandrels
A characteristicthat is a byproduct of the
evolution of some other characteristic,
rather than a direct product of adaptive
selection (after Stephen Jay Gould)
Examples: Language, Culture, Religion etc.
But are these merely byproducts?

Right Vs. LeftIdeologies
Rightists:
Conservatives
Religious
Sexual monogamists
Uni-culturalists
Uni-linguists
Racism
Naturalists
Leftists
Liberals
Atheists/Agnosts
Sexual liberalists
Multi-culturalists
Multi-linguists
Egalitarianists
Scientists
Felix Bast
57.
Marxism vs. NaturalSelection
Marxism and its ideology of welfare state/utopia is
unnatural; there is no struggle for existence and no natural
selection
Unequal distribution of wealth is natural order
Felix Bast
Right: Speciation; Left:Hybridization
Majority of Rightist perceptions are not merely spandrels, but
specific adaptive selection mechanisms that act in unison to
minimize intra-population variability, and therefore contribute
directly in speciation
In contrast, Leftist ideologies are scientific inventions that
foster hybridization of diverging populations by means of
multiculturalism, liberal sexuality and egalitarianism.
NatureVs. Nurture
Question is does the humanity want to split or not!
Felix Bast
60.
Left-Right Conflict
Conflictbetween Leftists and Rightists, and scientists and
naturalists, have analogy in the form of shared abstraction,
and is of enormous significance for determining future of our
species; as our future eventually depends on which of these
ideologies wins.
Felix Bast
61.
Future of humanity
If Right, we will embrace naturalism, continue to be territorial
animals (ultra-nationalism/jingoism), demote
multiculturalism, and are eventually set out for
speciation…Evolutionary autopilot
Emotion > Amygdala
if Left, we will espouse nurturism (science), continue to be
anti-nationalists, promote multiculturalism, and will continue
to hybridize (no speciation)
Logic > Cerebral Cortex

A Word onHuman Rights
Always remember pale blue dot perspective
Like you, animals have rights too. Plants
and microbes too. Mosquitos and
pathogenic microbes too.
Non-living “matter” has its right too;
world’s oceans, rivers, mountains;
entire earth and entire universe!
