Had recently been rediscovered when
Aquinas was working
Influenced Aquinas' ideas
Morality is an innate understanding
present in everyone
Basic idea
There is a natural order determined by a
supernatural power:God
Rooted in our human nature and
our search for happiness/
fufillment
We should use our reason to discover our purpose
It's following God's plan
We have a rational nature given
by God
Natural laws are
universal and unchanging
Perfection
Humans are made in the image of God
so our aim is to achieve perfecton
Impossible to achieve in this life
We discover how to achieve this
perfection by following reflections
of Natural Moral Law
1- Eternal Law
principles by which God made
and controls the universe
We can't fully understand them
We can only see reflections of it
2-Divine law
law of God
revealed in the Bible
A reflection of eternal law
can only be seen by those
who believe in God
3- Natural Law
A natural sense of
good within all
humans from God
Doesn't depend on
belief in God
reflection of eternal law
We need to use
reason to apply it to
a situation
4-Human laws
e.g. laws
Stoics
God is everywhere, in everyone
Humans have a divine spark
within them
The divine spark shows us how
to live according to God's will
Humans must use reason to
understand nature/ cosmic laws
We have a choice whether or not to
follow these laws
Good
Do good avoid evil
most fundamental inclination
we are designed for perfection so
would not knowingly pursue evil
real and apparent good
we must use our reason to
discover which is the real
good
Both the interior act and exterior
act must be good
actions are
intrinsically good or
bad
do good, be closer to God
an action can't just be good
for you but also the rest of
society
Precepts
Primary precepts
apply to everyone without
exception
a direct reflection of eternal law
W.O.R.L.D
worship of God
Ordered society
Reproduction
Learning
Defence of
the innocent/
preservation of
life
Secondary precepts
dependant on our own judgements
can lead to faulty reasoning
require experience and
use of reason
Doctrine of double effect
it's always wrong to carry out a
bad action to bring about
good consequences
it's sometimes right to do
a good thing knowing it will
bring bad consequences
Evaluation
strengths
clear to follow
deductive-doesn't just tell you
what to do
Helps us follow nature
based on human reason
values human life equally
Promotes order in society
fits with
christian
beliefs
common sense
fair-applies to everyone equally
doesn't require a belief in God
both absolute and relative
secondary precepts make it flexible
secondary precepts are
easy to work out
gives a universal moral code:
primary precepts are things most
cultures/religions would support
doctrine of double effect can
overcome problems
Weaknesses
less applicable if
you don't believe
in God
difficult to determine what is natural
e.g. death is natural, should we stop
trying to prevent it?
Kai Nielson- different
people/cultures have different
ideas about what is right
What happens when precepts
contradict each other?
not everyone tries to do good, some
people intentionally do wrong
Aquinas said all humans have the same
purpose- in the Bible God gives different people
different purposes
Darwin-living things are
naturally motivated by the will to
survive not a divine pupose
Unfair- reproduction is a precept, Aquinas was
a monk,said it was okay he didn't reproduce as
long as others did, could use this justification
to break any precept suggests rules don't apply
to everyone,
Barth- genesis 3 shows human reason is fallible
Vardy criticised the view of sex
Moore:naturalistic fallacy, just because we can
do something doesn't mean we ought to
