1. There are different kinds of law, including divine law, natural law, canon law, and civil law. Natural law participates in divine law and is known through reason, while civil law is man-made. 2. Basic human goods include life, knowledge, play, friendship, religion, and integrity. These goods form a hierarchy and serve as the basis for deriving more specific moral precepts from the fundamental principle of doing good and avoiding evil. 3. Through free choice, a person shapes their own moral character and identity. Repeated choices to do good or evil over time determine the kind of person one becomes.

5. Divine Law
Divine Law is that which is enacted by God and made known to
man through revelation. We distinguish between the Old Law,
contained in the Pentateuch, and the New Law, which was
revealed by Jesus Christ and is contained in the New Testament.

6. Canon Law
Canon law (Church law) is the body of laws and regulations
made by or adopted by ecclesiastical authority, for the
government of the Christian organization and its members.

7. Civil Law
Civil law: man made law. Can be just or unjust, depending
upon how it squares with natural law. I.e., one must be 18 in
order to vote, 19 in order to drink, one must drive on the
right side of the road, etc.

8. Natural Law
Cicero writes of the natural law: “True law
is right reason in agreement with Nature...it
is of universal application, unchanging and
everlasting.... we need not look outside
ourselves for an expounder or interpreter
of it. And there will not be different laws at
Rome and at Athens, or different laws now
and in the future, but one eternal and
unchangeable law will be valid for all
nations and for all times, and there will be
one master and one rule, that is, God, over
us all, for He is the author of this law, its
promulgator, and its enforcing judge.”

9. Civil and Natural Law
Martin Luther King Jr. wrote in his Letter from the
Birmingham Jail: “Now what is the difference between
the two? How does one determine when a law is just or
unjust? A just law is a man-made code that squares with
the moral law or the law of God. An unjust law is a code
that is out of harmony with the moral law. To put it in the
terms of Saint Thomas Aquinas, an unjust law is a human
law that is not rooted in eternal and natural law. Any law
that uplifts human personality is just. Any law that
degrades human personality is unjust. All segregation
statutes are unjust because segregation distorts the soul
and damages the personality. It gives the segregator a
false sense of superiority, and the segregated a false
sense of inferiority. …”

10. Natural Law
First principle of speculative reason:
Nothing can both be and not be at the same time and
in the same respect.
First principle of practical reason:
Good is to be done, evil is to be avoided

11. Part II – The Good

12. The Good
The good: that which all things desire. All things desire
their own perfection, that is, their own complete flourishing.
Human beings have natural inclinations or desires (to be
distinguished from acquired desires, and/or perverted
desires).

13. Apparent goods
True goods
Apparent goods appear to be
perfective of the human person,
but they are destructive of the
human person.
True goods are truly perfective
I.e., a poison apple, associating of the human person. Self-
with criminals, an adulterous
relationship, living a life of total
control, honest friendships,
leisure without ever working, healthy foods, etc.
etc.

14. Sensible Goods
Some of the desires (goods) we have are common to animals.
These goods are sensible goods (desire for warmth, sense
pleasure, etc).

15. Intelligible Goods
But other desires (goods) are specifically human. These latter
goods are intelligible (known via the intellect), and so they
have no color, taste, feel, etc. For example, friendship cannot
be sensed, nor can justice.
This is not justice, but a
symbol of justice
unintelligible to a brute
animal

16. Natural Law
From these intelligible human goods (natural), more specific
moral precepts (rules, regulations, laws) can be drawn out.
If we know what is humanly good, we can begin to draw out
the more specific demands of natural law.

17. Human Goods
• Religion: God is the Supreme Good, and so that part of
justice that seeks harmony between oneself and God is
called religion.
• Integrity (integration of the elements of the self, harmony
between reason and my choices, and the will and the
passions)
• The Common Good (sociability): The harmonious
relationship that exists between oneself and the civil
community as a whole.
• Marriage/family.
• Friendship: relationships based on common qualities and
interests.
• Knowledge
• Leisure (the enjoyment of the beautiful/art and play)
• Life (bodily goods)

19. External Material Goods
Wealth and Shelter
These serve human life
and the higher
goods, such as truth,
leisure, friendship,
etc.

20. Goods of the Body
» Life (health)
• Pleasure

21. Life
• The human person has a
natural inclination to
preserve his life; for he
sees his life as basically
good. That is why he acts
to preserve it, and why
married couples choose to
beget life.

22. Goods of the Soul
Intellect and Will
Intellect
Knowledge Contemplation of Beauty
(Art/Play)

23. Knowledge
• We desire to know, to contemplate. Man has
a natural sense of wonder. Human beings ask
questions, seek answers, wonder about the
causes of things. Man is a knower.

24. Leisure (Contemplation
of the Beautiful)
• Man is inclined to behold
the beautiful. Beauty
captivates us, whether it is
beautiful music, a beautiful
sunset, a beautiful painting,
a beautiful face, or a
beautiful life.
• Although the possession of
truth is a distinct good,
truth is beautiful, especially
in its order. The higher we
climb (wisdom), the more
beautiful truth becomes. In
fact, truth and beauty are
one in God.

25. Leisure (Making
and Play)
• Man is a maker. He
loves to produce or
make things. He likes
to build, to play
(games/sports), to
create, to recreate,
simply for its own
sake. Making and
play are intrinsically
good.

26. Religion
Goods of the Will
Integrity
Sociability/the common good
Marriage/family
Friendship

27. Goods of the Will
Friendship: relationship founded upon
common qualities and common interests.
3 types based on:
• Pleasure
• Utility (useful friend)
• Benevolence
(genuine friendship):
friend is loved for his
sake, not for the sake of
what he does for me
(I.e., useful or pleasant
to me)

28. Goods of the Will
Marriage/family
• Man is inclined to marry, to give himself
completely to another, to belong to
another exclusively and permanently in
one flesh union that is open to the
begetting of new life. Both husband and
wife will to beget human life because
goodness is effusive, and their unique
conjugal relationship is good.

29. Goods of the Will
The Common Good of the Civil
Community
Man is a social and political animal.
He enters into relationship not only
with friends, but with the civil
community as a whole. There is a
difference between his own private
good and the common good of the
whole. Just as a hockey player has
his own private scoring record, his
end as a player is a common good,
namely victory for the whole team.
The common good is a good in which everyone can participate without
diminishing any other member’s share in it. Just as a good player thinks of the
team before his own private scoring record, a good human person lives for the
common good, not merely his own private good. The criminal is different in that
he has no regard for the common good, but puts himself before civil community as
a whole.

30. Goods of the Will
Integrity (Virtue)
• Man is inclined to seek integration within
himself, an integration of the complex elements
of himself. This is because he seeks to be most
fully, and one (along with good, beauty, and
true) is a property of being. He is inclined to
bring about a more intense unity within
himself, namely 1) an integration between truth
and his acts, 2) his actions and his character, as
well as 3) his will and his emotions. Bringing
order to the passions (cultivating temperance
and fortitude) is good in itself, but is also a
means to a higher end. A person aims to be
temperate and brave for the sake of possessing
the highest good (God), the possession of
which is threatened by excessive sensuality
and/or by inordinate fear and daring.

31. Goods of the Will
Religion
• Man aspires after what is higher than him
because he is aware of his thirst, among other
things. He beholds his own finitude and the
finitude of creation. He aspires to what is beyond
the temporal to the eternal, yet he cannot
transcend the limits of his nature. But he dreams
about it. He seeks to know the giver behind the
gift of his existence. As a spiritual nature, he is
open to the whole of reality, the whole of being
(universal being). He seeks to know the “whole of
reality”, that is, to possess the bonum universale.
We know from revelation that he is not going to
attain it on his own; Scripture reveals that this
can only happen through God’s initiative (divine
grace). He cannot, of his own nature, attain God.
If he is to attain the bonum universale, it can only
be through another gratuitous giving, distinct
from creation (divine grace). He depends upon
the divine initiative. In fact, even his own natural
happiness is dependent upon the gratuitous self-
giving of others; for he cannot force people to be
his friends. And so this dependency upon the
divine initiative is not incongruent at all, for man
knows already that an element of his own
happiness is the feeling of having a debt that
cannot be paid.

32. These intrinsic human goods form a hierarchy
Although human
goods are good in
and of themselves
and are sought for
their own sake, they
also exist “for the
sake of” higher
goods

33. Part III - Character

34. Character
Moral: from the Latin mores: character. Moral Identity: the kind of
person one is or has made oneself to be.
Morality is not about choices that promise to bring about
an external state of affairs most conducive to the quality
of life one desires for oneself or others.

35. Rather, it is about the making of character.
We determine our character, our moral identity, by the
free choices that we make, and our very destiny is
determined by the kind of persons we’ve made ourselves
to be.
Your character is more intimately yours than anything
else you may have.

36. The human person is like a blank cheque. He has an already
given structure (I.e., human nature with definite powers), but there
is a space for him/her to “fill”, to complete, and this is one’s
moral identity or character.

37. Character vs. Personality
Character is not the same as personality.
You can have a great personality, but
depraved character, like serial killer Ted
Bundy on the left.
You can also have a grumpy, or bland
personality, but saintly character.
Much of our personality is determined,
either inherited or environmental.
But character is entirely ours.

38. Choice
(the relationship between what I choose and what I am)
doing & being
I choose to lie I become a liar
(even a nice liar)
I choose to steal I become a thief
(even a nice thief)
I choose to kill I become a killer
(even a nice killer)
I choose to gossip I become a gossip
(yes, even a nice gossip)

39. Man is an artist who sculpts his
own moral identity, the kind of
person he is or is becoming. By
my own choice, I become either a
good person, fully orientated
towards “the good” (God, who is
the Supreme Good), or an evil
person, that is, a person deficient
in my relationship to the entire
spectrum of human goods.

40. Part IV – Secondary Precepts of
Natural Law

41. Secondary Precepts
The first principle of morality is “good is to be done, evil is to be
avoided”.
This, however, is very general. It breaks down into more specific
moral precepts when seen against the background of the basic
human goods.
Human goods
Specific
First principle precepts actions

42. Secondary Precepts
One notices that the basic human goods form
a hierarchy:

43. God
Society
Family (others)

44. Good
is God
to
be Family
done,
Evil Others (the social whole)
is
to Individual good
be
avoided
Given the first principle of practical reason and the human goods,
one can draw out the following practical implications or precepts

45. Secondary Precepts
1. God is to be loved above all things (Recall that the virtue of
religion is the most perfect part of the virtue of justice)
2. One ought to render due honour to one’s parents (The virtue of
piety)
3. One ought to reverence the marriage bond
4. Do not harm others (One ought not to do anything
that harms the common good of the civil community –
the virtue of patriotism

46. Do not harm others
One ought not to do anything that harms
the common good of the civil community.
This precept can be logically expanded
One must direct one’s life for the common good (general justice).
4a) Hence, one ought not to act purely on the basis of emotion, either on the
basis of fear, aversion, hostility, or desire for sensible goods, but ought to
act on the basis of reason, in pursuit of intelligible goods.
4b) One ought not to act individualistically for intelligible human goods, but
in community with others.
4c) One ought not to treat certain others with a preference based purely on
feeling, unless a preference is required by human goods. In other words,
one ought always to treat others in a way that respects their status as
equal in dignity to oneself.

47. Do not harm others
4d) One ought not to willingly destroy an instance of an intrinsic human good for
the sake of some other intrinsic good. In other words, one must not do evil to achieve
good.
4e) One ought not to treat another human person as a means to an end. Persons
must be loved, not used; things must be used, not loved.

48. 5. One ought not to lie (an immediate violation of integrity)
6. One ought not to take what rightfully belongs to another (property)

49. Part V – The Elements of the
Human Act

50. • Moral Object
• Motive
• Circumstances

51. Moral Object
• Answers the question: What is being done?
What are you choosing to do?

52. Motive
• Answers the question: Why is this being
done? What is the reason why you are
choosing this course of action?

53. Circumstances
• When? Where? How? Why? Who? By
what means?
• A moral circumstance modifies the act, but
it does not cause the act to be the kind of
moral act that it is.

54. Moral Principle
Evil is a deficiency, a lack of something that ought
to be there.
Therefore:
• In order for an action to be morally good,
all three elements must be good.
• If any of the elements are evil, the entire
action is evil (defective).

55. Example (Moral Object = Evil)
• Moral Object: A married man has an affair
(adultery).
• Motive: In order to comfort the woman with
whom he’s having an affair.
• Circumstances: She’s depressed, she’s
married but going through a tough time, etc.
Secondary precept violated: revere the marriage bond (do not
commit adultery)

56. Example (Motive = Evil)
• Moral Object: Helping an old lady cross the
street.
• Motive: Merely in the hopes that she will
give you some money.
• Circumstances: Winter, icy road, need
money for cigarettes, etc.
Secondary precept violated: One ought not to treat another
as a means to an end.

57. Example (Circumstances that render an
otherwise good act immoral)
• Moral Object: Practicing my putting stroke.
• Motive: In order to improve my game.
• Circumstances: Where? At a funeral home
with nice green carpet. When? At my
mother’s funeral wake.
Secondary precept violated: Lack of due reverence for the
deceased. One ought not to treat certain others with a preference based
purely on feeling, that is, to treat others in a way that fails to respect their
status as equal in dignity to oneself.

58. Part VI - The Principle of Double
Effect

59. Sometimes an action has two effects: a good effect
and an evil effect. What does one do?

60. The Conditions
There are certain conditions which must be observed
before one may perform the action in question. Should
any of these conditions be violated, one may not
perform the action.

61. The Conditions
1. The action itself (which has two
effects) must be a good action, or at
least morally indifferent. In other
words, it cannot be an evil act.
Otherwise, we'd be doing evil to
achieve good.

62. The Conditions
2. One must not positively will the
evil effect. That is, one must not
intend the evil effect. One may only
permit or allow the evil effect.
Permitting and intending are two very
different ways of relating to human
goods.

64. The Conditions
3. The good effect must proceed
directly from the action and not from
the evil effect. For this would
involve doing evil to achieve good.

65. Here, the good effect proceeds from the evil
effect. If this were the scenario, one would
have to will the evil effect in order to
achieve the good effect. This violates the
second condition. For one must not will
evil for the sake of a good.

66. The Conditions
4. The good effect must be
sufficiently desirable to compensate
for the allowing of the evil effect.

70. Intending vs. Accepting
No one intends to wear out their
shoes. One wills that they never wear
out, that they last forever.
But one accepts the inevitable. One accepts the fact that when
I choose to wear my shoes, they are going to wear out.
