DEEP Ethics
Neil greenberg
2An ETHOLOGICAL Approach to the Ethics of
human-animal interactions
- Causes and consequences of behavior are both
proximate and ultimate - Complementary questions representing relevant
biological variables (DDEEP ETHOLOGY) - Epigenetic cascade of interacting biological and
environmental influences
3Domains of Ethology
- Morphology
- Development
- Ecology
- Evolution
- Physiology
- DEEP ethology
4The Ethological Perspective
- The most proximate is the neuromuscular junction
- (neural, endocrine, information flowing through
the organism) - The most remote aspect of causation is
evolutionary - (traits that serve fitness are transmitted
across generations)
- The way we relate to other individuals (of our
own or other species) is a behavioral pattern. - And that behavior can be best illuminated by a
coordinated consideration of its proximate and
ultimate causation

6BEHAVIOR is a result of INTERNAL and EXTERNAL
influences
- INPUT INTEGRATION OUTPUT
- INPUT involves stimulus, sensation, selective
perception - INTEGRATION involves how that information
interacts with previous information somehow
represented in the brain the path information
takes - OUTPUT involves selection of a response
7INTEGRATION
- MOTIVATION -- AFFECT -- COGNITION
- These critical functions of the brain influence
behavior in slightly different ways. - Their activation suggests that during
integration, information can take different
pathways through the brain, engaging these
functions in varying proportion depending on the
perceived urgencies of the moment.
8DISTRIBUTED systems INTEGRATED in the service of
behavior
- MOTIVATION
- Fundamental biological needs
- AFFECT
- Energizing action depending on perceived urgency
- COGNITION
- Modulated by cognitive processes such as stimulus
feature detection and predicting the future -
9MOTIVATION -- AFFECT -- COGNITION
- MOTIVATION associated with fundamental needs
the nexus for coordination is hypothalamus - AFFECT associated with energizing influence of
emotions the nexus for coordination is the
limbic system - COGNITION associated with cognition, planning,
control of behavior coordinated at lower
centers (instincts, impulses) the nexus for
coordination is the prefrontal cerebral cortex
10MOTIVATION -- AFFECT -- COGNITION
- MOTIVATION / hypothalamus
- AFFECT / limbic system
- COGNITION / cerebral cortex
- These functions and their associated centers
make more-or-less use of more-or-less OPEN or
CLOSED programmes of responding
11DETERMINISM
- Variables determining behavior are rarely
exclusively - Biological (genetic or nature) or
Environmental (nurture) - They are
- Epigenetic reflecting the cascade of interacting
genetic and environmental variables (Open and
Closed Genetic Programs)
12DECIPHERING DETERMINISM
- . . . grant me the serenity to accept the things
I cannot change, - . . . courage to change the things I can,
- . . . and the wisdom to know the difference.
-
- (from Reinhold Neibuhrs adaptation of a 14th c
English prayer)
13DECIPHERING DETERMINISM
- Although real wisdom may be beyond science
- . . . the aim of science is not to open the
door to everlasting wisdom, but to set a limit on
everlasting error. -
- (from Bertolt Brechts Life of Galileo)
14Is Error Detection the way the brain work?
- It certainly is the way science works!
- "I haven't failed, I've found 10,000 ways that
don't work. - -- Thomas Edison
- "Knowledge increases not by the matching of
images with the real world ... but by a
relentless bias toward the perception of error."
- -- Kenneth Boulding
- "When you have eliminated the impossible,
whatever remains, however improbable, must be the
truth. - -- Sherlock Holmes
15An Ethical Dilemma
- The long-standing rationalist tradition in moral
psychology emphasizes the role of reason in moral
judgment. - A more recent trend places increased emphasis on
emotion.
16The Runaway Trolley
- A runaway trolley is hurtling toward five people.
They will all be killed - BUT you can just about reach and throw a switch
that will steer the trolley onto a spur, where it
will kill just one person instead of five. - Should you throw the switch?
17The Runaway Trolley
- A runaway trolley is hurtling toward five people.
you are standing next to a large stranger on a
footbridge that arches over the tracks. - Because you are small but agile, the only way to
save the five is to push the large stranger off
the bridge onto the tracks below it is certain
that he will die, but his heavy body will stop
the trolley, saving the five others. - Should you push the stranger to his death?
18NEUROETHICS
- Using fMRI, researchers showed that individuals
judged personal moral dilemmas using areas known
to regulate emotion (medial frontal, posterior
cingulate, and angular gyri). - areas regulating working memory (middle frontal
and parietal) were less active, - compared with neural activity during judgments of
nonmoral dilemmas and impersonal moral dilemmas. - Participants also had longer reaction when making
difficult, personal, moral decisions that
adversely affected others. - Greene et al. An fMRI investigation of
emotional engagement in moral judgment. Science
Sept 14, 2001 2932105-2108
19- Another team of researchers investigated the
neural correlates of moral emotion in normal
individuals using functional magnetic resonance
imaging (fMRI). - Because damage to the orbitofrontal cortex can
result in a lack of empathy and antisocial
behaviors while leaving social cognition and
basic emotions intact, Moll colleagues
hypothesized that this brain region would be more
activated by the visual perception of stimuli
evocative of moral emotions compared with
emotional stimuli without moral content - In addition, they predicted that basic and moral
emotions would evoke overlapping activations in
brain regions involved in emotional processing,
such as the amygdala, insula, and subcortical
nuclei.
20NEEDS
- Organisms have several more-or-less obvious NEEDS
related to their capacity to prosper - Behavior can be viewed as an adaptation that
helps organisms COPE with challenges to those
needs
21NEEDS
- Maslows need hierarchy
- Physiology (food, drink, exercise)
- Safety (security, order, protection)
- Belonging ( sociability, acceptance, love)
- Esteem (status, prestige, acknowledgment)
- Self-Actualization (personal fulfillment)
22NEEDS PHYSIOLOGY
- HOMEOSTASIS . . .
- "It is the fixity of the milieu interieur which
is the condition of free and independent life" - (Claude Bernard, 1878)
23HOMEOSTASIS . . .
- The highly developed living being is an open
system having many relations to its
surroundings. - . . changes in the surroundings excite
reactions in this system, or affect it directly,
so that internal disturbances are produced. . . - the coordinated physiological reactions which
maintain most of the steady states in the body
are so complex, and so peculiar to the living
organism, that it is suggested that a specific
designation for these states be employed--
homeostasis" (W.B. Cannon 1929)
24NEEDS Physiology
- Food comes first, then morals (Brecht)
- Picassos Frugal Repast (1904)
25NEEDS Safety
- (security, order, protection)
- For a mans house is his castle
- (et domus sua cuique est tutissimum refugium Sir
Edward Coke, - The Third Part of the Institutes of the Laws of
England, 1628)
26NEEDS Belonging
- (sociability, acceptance, love)
- He who is unable to live in society, or who has
no need because he is sufficient for himself,
must be either a beast or a god. - (Aristotle, Politics bk. 1, 1253a 279)
27NEEDS Esteem
- (status, prestige, acknowledgment)
- "I have a burning wish that you should know me
wholly, wholly. Why is it so unutterably
beneficial, the thought that someone besides
myself knows me?" - (Karen Danielsen writing about Oskar Horney)
28NEEDS Esteem
- (status, prestige, acknowledgment)
- ". . . the most terrifying burden of the creature
is to be isolated, which is what happens in
individuation One separates himself out of the
herd . . . . His creative work is at the same
time the expression of his heroism and the
justification for it. (Becker)
29NEEDS Self-Actualization
- (personal fulfillment)
- For most creatures, self-actualization is
manifest as - DIRECT and/or INDIRECT 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)
- Be all you can be . . . (US Army recruiting
slogan)
30Beyond Biology? spiritual
self-actualization
- Those who hunger for illumination, those who
see, remain on the fringe. They are derided,
they are treated as mad. But these few rare
souls resist and are vigilant. They have an
obscure need for spiritual life, for knowledge,
for progress. -
- (Wassily Kandinsky 1866-1944)
31Stressors and Coping ResponsesWhen needs are
not met . . .
- The organism manifests a remarkable sense of
biological priorities - A stressor is a real or perceived challenge to an
organisms ability to meet its real or perceived
needs.
32STRESS . . .
- Is both a cause and a consequence to be more
precise, we should speak of - STRESSORS challenge our capacity to meet our
needs, and - STRESS RESPONSE our body's attempt to cope with
a stressor by evoking neural and endocrine
compensatory mechanisms.
33Coping . . .
- STRESSORS are internal or external changes which
by challenging an organisms ability to meet its
needs evokes a coordinated coping response - . . . constrained by a threshold for detection of
the change, for attention based on real or
perceived relevance, and capacity to respond at
any particular level once the challenge is
detected.
34COPING RESPONSES constraints of the system
- Input (stress can change the sensitivity of sense
organs (e.g., Gandelman 1983) resolve
competitive parallel afferent pathways,) - Integration (receptive field modulation stress
can affect arousal, selective attention (e.g.,
Archer 1973, R.J. Andrew 1972) differential
regional sensitivity to hormones or
neurotransmitters (e.g., Amy Arnsten 2000)
control of microcirculation (e.g., Palmer 1986) - Output (resolve competitive parallel efferent
paths to action energetic reserves and the
ability to mobilize them)
35STRESS can drive the adaptive process
- . . . continuous assimilation of internally
mediated consequences of the organisms action on
the environment and the resulting accommodation
of these action schemes into the previously
formed structure - (Piaget 1980)
36ADAPTATION is . . .
- The processes by which organisms or groups of
organisms - maintain homeostasis in and among themselves in
the face of both - short-term environmental fluctuations and
long-term changes - in the composition and structure of their
environments. (Rappaport, 1971)
37Efficiency Many challenges, few responses
- the manifest versatility of the organisms
coping responses presupposes a nervous system
endowed with an unfailing sense of biological
priorities, and is characteristic of the
economy with which the body defends itself. - Instead of depending on a large number of
separate mechanisms, each one of which is
exclusively reserved for its own particular type
of emergency, the body improvises responses to
the threat of injury by assembling new
combinations of pre-existing functions.
(Miller, 1978118).
38PATHOLOGY
- There are many systems in the body which, because
of misuse or misfortune, may have their services
to the organism as a whole so altered as to be
actually harmful. - Thus vicious circles of causation become
established which may lead to death . . .
39Optimal Arousal
- A range of stimulation is not only tolerable, it
is desirable (adaptive scope) - But stimuli from different sources may contribute
to this range - So a stimulus is meaningful only in the context
of possible convergence with others
40Do ethics meet needs?
- Social contract theory is the view that morality
is founded solely on uniform social agreements
that serve the best interests of those who make
the agreement.
41Are ethics outside nature?
- When T.H. Huxley lectured on Evolution and
ethics at Oxford he regarded ethics as outside
of nature -- a human invention. - Dawkins in The Selfish Gene appeared to agree
. . . let us try to teach generosity and
altruism, because we are born selfish. - St. Augustine would agree.
42Are ethics outside nature?
- Altruism acting in a way that diminishes ones
fitness in order to contribute to the fitness of
another - Direct Indirect Fitness (personal fitness
the fitness of others with whom you share more or
less genes) - Is there any real altruism?
