Enquiry of the Principles of Morals
By David Hume
Hume’s Approach
• Hume takes a generally naturalistic approach
to explaining behavior and ideation. His
earlier work, A Treatise of Human Nature,
sought to ground philosophical discussion in
observations of the kinds of beings we are.
• His approach to ethics is no different, and the
Enquiry represents a refinement of his
perspective expressed in the Treatise.
Impressions vs. Ideas
• One distinction crucially important to
understanding Hume:
• Impressions: Immediate information from the
senses.
• Ideas: are complex notions built up out of our
impressions.
From whence is morality derived?
Reason
• Moral proofs are supplied
• Moral arguments are
intelligible, and nobody
argues about mere
sentiment
Sentiment
• Nobody has strong
reactions to purely rational
exercises.
• Why do we care so much
about morality if it is
ultimately derived from
reason?
Utility
• Hume’s main purpose is to settle the question
of the ultimate source of morality, but puts off
the question until the end of the essay.
• Whatever the answer to the question, it is
worth pointing out that what is useful to us
and what is dangerous or useless to us tends
to affect how we feel about the beauty or
ugliness of things.
Our aesthetic impressions:
Useful and thus beautiful:
• Waving fields of grain,
loaded vineyards,
cooperation, etc.
Useless and therefore ugly:
• Brambles, thorns, serpents,
etc.
When appearances deceive:
• Of course, Hume concedes, some things look
terrible but are really good for us, and some
things look good that aren’t really good.
• It is the task of our faculty of reason to tell the
difference between them by investigation and
the application of reasoning.
Benevolence as a social virtue:
• Hume devotes Section II to an examination of
benevolence (good-will).
• It is notable that benevolence is a purely good virtue.
Wealth or power can be misused or envied, but pure
benevolence is not susceptible to either. This is an
impression we receive from those who demonstrate
benevolence (it is sentiment).
• As before, some things look benevolent (e.g. almsgiving) but are ultimately not useful. It is the task of
reason to sort these things out (to give us an idea of
what benevolence is).
Justice:
• Hume devotes the third section to this second
major social virtue.
• To illustrate some tings about the anture of
justice, he asks us to consider some thought
experiments:
Resources:
Abundance
• In the situation in which
there is more than enough
of everything for everybody,
the rules of justice would be
meaningless.
• It would be a kind of
paradise.
Scarcity
• In the situation in which
there is not enough of
anything for anybody, the
rules of justice are
suspended.
• In a shipwreck, it is no crime
to grab onto what floats,
whether it belongs to you or
not.
Justice and Resources:
• Given that we live in a situation with less than
plenty, but not so little that survival is our only
concern, the laws of justice have application
for us.
Character:
A Just man among Ruffians
• In this case, the man must
grab a sword and buckler,
no matter who it belongs to
and defend himself.
• The rules of justice are of no
benefit without
cooperation.
A Ruffian among the Just
• The rules of Justice are
suspended in the case of
the ruffian.
• Ordinarily we would not be
able to fine or imprison
people, but in this case, we
must to preserve justice for
everyone who cooperates.
A just-so story of the origin of Justice:
• Of course the “state of nature” never really
existed, but the idea of it explains why certain
people (probably families to start with) band
together and cooperate for mutual benefit
and protection.
• Say that then many families unite to the same
purpose, you have the beginnings of a larger
scale society.
Particular rules of Justice
• Initially, it seems as if we ought to reward
those who would do the most good with the
most resources (and much of our social
structure is arranged to encourage this). This
is called meritocracy
• Hume says it is difficult because merit is so
obscure and difficult to pin down
Absolute equality
• Although there is certainly something wrong
with too extreme a rich/poor gap, Hume
points out that absolute resource equality
would not work.
– The differences in peoples’ talents would make
the absolute equality not last long.
– If we continually redistribute things to maintain
absolute equality, people have no incentive to do
anything useful at all.
The origins of Justice
• Some parts of our notion of justice seem
instinctual, while others are clearly the result
of reason and custom.
• Both, however, are susceptible to the ultimate
usefulness to society at large.
Natural mechanisms that encourage
justice and morality:
• When we witness others in pain, we often feel
some measure of that pain ourselves, or have
a strong reaction to it. Same with the
pleasures of others.
• This represents mechanisms of sympathy and
empathy whereby we recognize what causes
good for others and bad for others.
• These mechanisms tend to reinforce moral
and just cooperation.
The source of ethics
• Hume finally turns back to the initial question.
• In many ways both positions are right but
insufficient.
• Hume concludes that without the particular
sentiments that we have we cannot explain
moral feelings and reactions. However, reason
has a crucial role to play in examinations of
what is useful to us and what is not.
