Transcript The Science of Morality
Philosophical Foundations
Three different domains of Morality
Character
Action
Consequences
Different ethical theories focus on the moral appraisal of
one of these domains
Character
Virtue Ethics
Aristotle
Philosophical Foundations
Two ways to evaluate action
Deontological – Ethical decisions and actions are based on
Rational appraisal
Sentimentalism – Ethical decisions and actions are based on
emotional appraisal
Evaluating Consequences
Utilitarianism – ends justifies the means
Jeremy Bentham
John Stuart Mill
David Hume (1711-1776)
Sentimentalism
Moral distinctions are not derived from
reason, but from Emotion
Our emotions enable us to evaluate the
difference between virtue and vice
• Emotions provide an objective measure for morality
based on a common sentiment towards humanity
• Although moral virtue is rare, persons do not act
purely out of self-interest
Deontological Ethics
Immanuel Kant
(1724-1804)
Moral principles are based on a rational
appraisal
Morality is based on duty
Categorical Imperative
Universal Principles of Conduct
Moral laws are based on rational principles
that are universally binding
Jeremy Bentham
(1748-1832)
Utilitarianism says that the Result or the
Consequence of an Act is the real measure of
whether it is good or bad.
Utilitarian Calculus
In determining the quantity that may be
produced by an action, we evaluate the possible
consequences
Those consequences that lead to a greater
amount of happiness are good
Jonathon Haidt
Julie and Mark are brother and sister. They
are traveling together in France on summer
vacation from college. One night they are
staying alone in a cabin near the beach. They
decide that it would be interesting and fun if
they tried making love. At the very least it
would be a new experience for each of them.
Julie was already taking birth control pills, but
Mark uses a condom too, just to be safe. They
both enjoy making love, but they decide not
to do it again. They keep that night as a
special secret, which makes them feel even
closer to each other.
What do you think about that? Was it OK for
them to make love?
Morality Story
Jonathon Haidt
Social Intuitionist Model
Emotion serves as an intuition that directs our
assessment of a moral situation
Moral reasoning follows based on the intuition
Ad hoc explanation based on defending our
intuitions
Used to influence the intuitions of others
Thus, one feels revulsion at the idea of incest
in the story
Then, seeks to find a way to rationally defend
the intuition
Trolley Problem
Trolley Problem
Joshua Greene
Competing Processes Theory
Cognitive and emotional processes compete
in moral decision-making
Impersonal
Cognitive (Rational) Processes used in
appraisal
Thought of pulling a lever does not activate
emotional centers of brain
Personal
Emotional process used in appraisal
Thought of pushing someone more
emotionally engaging
Marc Hauser
Moral Decision-making based on Moral Module
Similar to Chomsky and Pinker’s view of language
module
Instinctive Moral Grammar directs analysis of
perceived actions
Most cognitive processes are unconscious and
implicit
Moral cognition is largely unconscious
Not developed through instruction
Not dependent upon religious institutions
Marc Hauser
Prior to emotional and cognitive moral appraisals
Evaluate actions based on three categories
Permissible
Obligatory
Forbidden
Color our perceptions
Constrain options for moral decision
Moral appraisal occurs within specific cultures,
but follows the grammar set by the moral module
Exemplars
Wesley Autry
Put his life in jeopardy to save
a stranger
Jumped onto subway train
tracks to cover a person in
danger
Later replied, “I don’t feel like
I did something spectacular; I
just saw someone who
needed help. I did what I felt
was right.”
Exemplars
The Story of Wesley Autry
Exemplars
Holocaust Rescuers
Risked their own life to
save Jewish persons
during the holocaust.
When asked, many
rescuers didn’t feel like
they did anything
extraordinary
They could not of
imagined doing
anything different
What is a Exemplar?
Common definitions
Someone who embodies certain admirable
traits
Serves as a point of reference
By observing an exemplary person, one learns
how to exercise a particular trait
For Virtuous exemplars
These persons have characteristics that are
essential for the moral life
These persons are examples for how to behave
morally
Aristotle and Virtue Ethics
Eudaimonia – happiness or the
good life
Virtues are those those aspects of
character that lead to a good life
Virtues flow naturally from the
character of moral exemplars
Exemplars are persons who have
developed certain habits that
embody moral virtues
Aristotle and Virtue Ethics
Acquiring virtue is not like
other intellectual pursuits
Requires “phronesis” or
practical wisdom
Virtues are acquired like the
skills of a master craftsman
More of an unconscious
process
Contemporary Virtue Ethics:
Linda Zagzebski
Exemplars are the starting point for virtue
ethics
Concrete example of virtue to begin the
development of conceptual definitions
Exemplars are distinguished by their
exercise of practical reason or phronesis
Exemplars have the right motive, at the
right time
Contemporary Virtue Ethics:
Linda Zagzebski
Motives are emotional states that lead to
correct moral actions
Each emotion has a thick concept that
represents the intentional object of the
emotional state
Emotions enable a person to see a situation
from a particular moral perspective
Their emotions ready them for action
Contemporary Virtue Ethics:
Linda Zagzebski
Emotions form the basic
dispositions of a person’s character
Enduring moral traits
Produces reliability and consistency in
moral character despite the context
Developmental perspective on acquiring
virtue
