3Who the Hell Do You Think You Are!?
- Are you nothing more than a squirming mass of
memories enveloped by an ego boundary? - At some level, we seem to know that what we call
matter, as the physicist David Bohm once
observed, is just a ripple on the ocean of
reality.
4The Natural History of the Self"
- But alongside our insignificance, we have the
sentiment that we are largethat we contain
multitudes, as the poet Walt Whitman so famously
said. - Part of the resolution of this seeming paradox is
that humans are part of one another. To be a
part of the main, as the poet John Donne put it,
is among the hallmarks of the mystical
experience.
5The Natural History of the Self"
- But mystical experiences are transformative!
- Sorry, Im not myself. I just had a mystical
experience - MYSTICAL EXPERIENCES are not only Ineffable, but
Noetic, Transient, and Passive - they may be facilitated by preliminary voluntary
operations, like meditation, but once it begins
it seems out of ones control as if he or she
were grasped and held by a superior power - William James 1918
6There are moments, and it is only a matter of
five or six seconds, when you feel the presence
of the eternal harmony ... a terrible thing is
the frightful clearness with which it manifests
itself, and the rapture with which it fills
you. Dostoyevski
7WHAT are our NEEDS?
Why do we need to know our selves?
- Health? Safety? Belonging? Prestige?
Self-Actualization? (Maslow) - For many of us, once other needs are met (or
rendered irrelevant), to become one with the
truth you seek is a key need. Attaining truth
can be a peak experience, and one that can, in
part, be facilitated or enhanced by an
understanding of the proximate (physiological)
and ultimate (evolutionary) aspects of its
natural history.
8The Natural History of the Self"
- DEEP ETHOLOGY the convergence of complementary
perspectives Development, Ecology, Evolution,
and Physiology - The evolutionary significance of KNOWING ONES
SELF - The LIMITS of KNOWLEDGE (the world is more
continuous than our fragmentary knowledge of it) - The SELF as concerned with CAUSES and
CONSEQUENCES (history and future) - TRUTH the convergence of correspondence and
coherence (expressions of the way the brain is
organized)
9At this point, to more fully understand the
relationship between humanity and nature, we can
invoke the powerfully integrative perspective of
DEEP ETHOLOGY
10DEEP ETHOLOGY
- Description
- Development
- Ecology
- Evolution
- Physiology
11SELF CONSCIOUSNESS
- "Before the connection of thought and brain can
be explained, it must be stated in elementary
form and there are great difficulties about
stating it. . . . Many would find relief at this
point in celebrating the mystery of the
unknowable and the "awe" which we should feel. .
. . - It may be constitutional infirmity, but I can
take no comfort in such devices for making a
luxury of intellectual defeat. . . . Better live
on the ragged edge, better gnaw the file
forever!" - (William James 1950177-199)
12DEEP ETHOLOGY
- Description
- We need to have consensus about the phenomenon
- Describing preceding and correlated phenomena
nibbles at causation, but - Post hoc ergo propter hoc
- if you cant explain something, describe the
hell out of it
13CAN the SELF be DESCRIBED?
- there are multiple attributes of SELF including
competing attributes any one of which can
dominate. - These ordinarily converge in varying proportion
on what we recognize as who we are. - As in other aspects of behavior, each of these
has a distinctive development, context,
evolutionary history and mechanism of expression.
14(No Transcript)
15Distributed but integrated systems for
motivation, affect, and cognition, mediate
behavioral patterns from reflex to reflection
- Homeostatic functions and archaic reflexes of
motivation are - energized by the systems of affect and
- modulated by more recent systems employing
cognition - The ensemble represents the self as well as the
outside world.
16SO WHAT IS THE SELF
- A graded integration of nested cognitive
abilities that yield a more-or-less unified sense
of who we are. - In James view, the self consists of
- The material Self
- The social Self
- The spiritual Self
17SO WHAT IS THE SELF
- internal self call it centripetal, in which
ones deepest core values are borne, nurtured,
reside, and provide an overarching personality - external self call it centrifugal, in which
the boundaries of ones competencies are defined
and extend out to influence those around us.
This is extrasomatory self, those external
expressions of inner meaning that are initially
manifest as we test, explore, and exercise our
competencies - . . . as in reafference (feedback that
fine-tunes our intended actions) - . . . supremely manifest as art.
18DEEP ETHOLOGY
- Development
- Progressive change within an individual
- Epigenesis genes affect and are affected by the
environment
19The scientist in the crib
- we were all scientists in the crib developing
and testing hypotheses about the nature of our
environments and how best to control them, how
best to relate to one another. - Like scientists, rejecting hypotheses that are
false - It is a necessary stage of our cognitive
development. It is the phenomenon of mind that
ultimately makes learning possible . . . and it
is the beating heart of the scientific method.
20DEEP ETHOLOGY
- Ecology
- Context geology, climate
- Context conspecifics, predators, prey
- Presents challenges (selection pressures) to
individuals or groups with which they must cope
to maximize their fitness
21DEEP ETHOLOGY
- Evolution
- Ultimate Causation (why?)
- Transmission of information between the
generations - Progressive change
22DEEP ETHOLOGY
- Evolution
- Bricolage (the pandas thumb)
- pleiotropy (collateral effects, epiphenomena)
- adaptive traits meet needs
23Bricolage using whats available minute
phenomena can be dramatically transformed e.g.,
from thermoregulatory reflex to social display
- feathers raised by pilomotor muscles
- an ancient autonomic theromregulatory mechanism
- ordinarily hidden
- displayed when aroused
24The Lizards Flag
- Erected by the hyoid apparatus
- an ancient mechanism activated by stress
- ordinarily hidden
- displayed when aroused
25MEETING NEEDS
- Maslows need hierarchy
- Physiology (homeostasis, health)
- Safety (security, order, protection)
- Belonging ( sociability, acceptance, love)
- Esteem (status, prestige, acknowledgment)
- Self-Actualization (personal fulfillment)
26MEETING NEEDS
- ALL our biological adaptations have been
preserved by natural selection because of their
ability to help us meet our needs more
effectively and efficiently. - THIS includes BEHAVIORAL PATTERNS
- Not the least of which is the creation of
narratives about causes and consequences. - Spiritual experiences are unusual states of
consciousness interpreted to support narratives
about unseen forces that appear to guide us.
27MEETING NEEDS
- Be all you can be . . .
- (US Army recruiting slogan)
- For most creatures, self-actualization is
manifest as fitness - "The aim of life is self-development. To realize
one's nature perfectly - that is what each of us
is here for. . . . - (Oscar Wilde, from The Picture of Dorian Gray)
28MEETING NEEDS
- Meeting NEEDS is the basic business of life.
When real (or perceived) needs are not met,
stress is created. - Organisms have ancient and powerful mechanisms
for relieving stress - Needs exist in a hierarchy of urgencies. When
the most urgent need is met, all the organisms
energy is focused on the next need.
29DEEP ETHOLOGY
- Physiology
- Proximate causation (how)
- Maintenance of homeostasis the dynamic balance
of multiple systems - Negative Positive feedback loops
- Input (e.g., sensation) integration (e.g.,
cognition, perception, memory) output (motor
coordination, endocrine activation)
30The mind consists of countless layers of
overlapping, interconnected nets, each sharing
millions of knots called neurons, and deployed to
catch and control whatever experiences will
advance our fitness -- our relative success in
the meeting of needs to survive and thrive. No
single net can catch much of anything of great
use, each catches fragments at best. Art
Organism
31What is the urgent need that is shared by those
who would know their selves
- We need to know the TRUTH
- We are powerfully motivated to develop the
highest possible confidence in the reality of our
beliefs . . . and their internal and external
validity - TRUTH is an amalgam of reality-testing
(correspondence) and story-telling (coherence).
These two separate functions of brain and mind
converge to give us confidence that empowers our
actions in the world.
32TRUTH in the BRAIN
- TRUTH is a BELIEF in which you have HIGH
CONFIDENCE - CONFIDENCE derives from specific neural functions
associated with - AFFECT (sensuous, emotional, empirical,
experiential, real) and - REASON (linear, narrative, coherent, ideal)
We can speak of two critical PROBLEMS and our
two coordinated COPING MECHANISMS
33SELF CONSCIOUSNESS
- THE BRAIN "multitasks" --lots of things go on
simultaneously --and often compete with each
other for control of behavior. Surely you have
had almost debilitating episodes of being unable
to "make up your mind?" There always seems to be
multiple explanations for phenomena -- which
shall you select? why that one? - --Art Organism
34TRUTH in the BRAIN
TRUTH is a quality of a belief we hold in our
heads -- It has met certain tests
- CORRESPONDENCE our experience of the world
matches the reality of the world reality
testing (Novelty evokes stress it is
anxiogenic it evokes the stress response) - COHERENCE our experience fits in with all our
other experiences story-telling (Familiarity
mitigates stress it is anxiolytic it relieves
stress)
35A Mind at Rest . . .
- There are two modes of knowing, through argument
and experience. Argument brings conclusions and
compels us to concede them, but does not cause
certainty nor remove the doubts in order that the
mind may remain at rest in truth, unless this is
provided by experience - --Roger Bacon, 1268 . .
36COHERENCE
- The pieces come together
- A congenital synthesizer, I held onto the dream
of a unifying theory (p312) - ". . . the years writing these two syntheses The
Insect Societies and Sociobiology were among
the happiest of my life" (p323) - -- EO Wilson in Naturalist (1994)
37 We NEED explanations
- Coherence helps us feel better A world that can
be explained even with bad reasons is a familiar
world. But on the other hand, in a universe
divested of illusions and lights, man feels an
alien, a stranger. . . .
Albert Camus
38TRUTH in the BRAIN
LEFT HEMISPHERE Coherence creates a stable and
internally consistent belief system (Ramachandran
1998) Probabilistic reasoning (Osherson et al
1998) Abstract object recognition (Marsolek 1999)
RIGHT HEMISPHERE Correspondence tests reality
and if damaged, confabulation runs
rampant (Ramachandran 1998) Deductive
reasoning (Osherson et al 1998) Specific object
recognition (Marsolek 1999)
Kant "The senses cannot think, the
understanding cannot see.
39What is the urgent need that is shared by those
who would know their selves
- SCIENCE and ART are the human endeavors that
seek truth - Foster our self-knowledge
- Explore beneath mere appearances
- Exercise and integrate our skills at intuition
(based on experience and sensory information of
which we may not be consciously aware) and reason
(organized coherent matrices of probable causes
and effects)
40"The intuitive mind is a sacred gift and the
rational mind is a faithful servant. We have
created a society that honors the servant and has
forgotten the gift. --Albert Einstein
41G????? sea?t??GNOTHI se AUTON
- To be an effective, competitive organism, we
would be wise to follow the advice of the Oracle
at Delphi - Gnothi se auton
- (Know thyself)
- Is this the primal function
- of art? Of science?
the ancient ruins of the sanctuary of
Apollo at Delphi. is spread out over the southern
slopes of Mount Parnassos, beneath the Phaidriad
rocks.
42What are my LIMITS?
- KNOWING who you are is an artifact of cerebral
mechanisms for helping you maximizing your
fitness! - Being ALL YOU CAN BE
- Emotions and cognition, ART and SCIENCE,
intuition and rationality, senses and reason, are
ways our minds tell us who we are and exercise
and extend our boundaries and potential
Vitruvian Man by Leonardo reflects
his conviction that all things can be measured
43- "The senses cannot think.
- The understanding cannot see."
- Immanual Kant
- Critique of Pure Reason
44The Natural History of the Self
- The LIMITS of KNOWLEDGE
- the world is known only in fragments . . .
a sense of continuity depends upon neural
mechanisms. - We have an instinctive conviction in an
intellectually accessible mechanistic order in
nature. (AN Whitehead 1967)
45We see the world not as it is, But as we are .
. .
(Talmud)
46What we know of nature is necessarily limited
- Reality is out there . . . truth is in here
- Our umwelt world of senses is limited to what
our sense organs can detect and we have evolved
to detect only that which is essential to
survival to the meeting of our needs. - One such need is for the connections that create
stories an understanding of the causes and
consequences of phenomena - A predictable world is much less stressful
47The organism imposes limits
- Science seeks (and often succeeds) in
transcending them We have prosthetic eyes and
ears . . . - BUT we live in our unique Umwelt our sensory
and perceptual world -- for example - Vision 390-780nm
- Hearing 20-20K Hz

52Causes and Consequences
- "A warp in the simian brain....made us insatiable
for patterns--patterns of sequence, of behavior,
of feeling-- connections, reasons, causes
stories." (Kathryn Morton, 1984) - . . . the need for a narrative is absolutely
primal (Oliver Sacks 1987)
53Connections
- The love of system, of interconnection, which is
perhaps the inmost essence of the intellectual
impulse . . . (Bertrand Russell, 1917)
54The biologists lensstress
- When our ability to accommodate real or perceived
needs is threatened, we experience stress Much
of our behavior is guided by the urge to minimize
uncontrollable stress. - Stress evoked for any reason positive as well as
negative changes we need to accommodate or cope
with, energizes our systems our perceptions,
our thinking, our actions. - Mild stress can be exhilarating, revealing our
great potential, intense stress can be
debilitating, even deadly, exhausting our
resources . . .
55The biologists lensstress is caused by
- Cognitive dissonance (mismatches between our
minds model of the world (derived from
correspondence and coherence) and the world as it
is) - Incomplete stories (the evidence on which we base
our understanding is necessarily fragmentary) - we ameliorate stress by extrapolating from areas
of confident knowledge to areas of ignorance.
Our biology does not require us to be perfect
just sufficient to be competitive and prosper - Relentless pursuit of (unattainable) perfection
leads us to being better than our competitors.
56Searching for truth . . . creating connections
57Searching for truth . . . creating connections
- We make the road by walking
58- "Our life is an appenticeship to the truth that
around every circle another can be drawn that
there is no end in nature, but every end is a
beginning, and under every deep a lower deep
opens" - --Ralph Waldo Emerson
59- "Our life is an appenticeship to the truth that
around every circle another can be drawn that
there is no end in nature, but every end is a
beginning, and under every deep a lower deep
opens" - --Ralph Waldo Emerson
60ACTION without INTENTION
IMPULSIVENESS Experience SPONTANEITY
- We are right to wary of IMPULSE (instincts,
emotions) - It is impulse control that distinguishes us
from lower animals
61Impulse control is what the prefrontal cortex is
all about
"The sleep of reason produces monsters"
