Augustine vs. Aquinas

If reason and faith conflict,
Natural or Philosophical Theology
Using reason alone Aquinas thought he
could prove:
The existence of God
The attributes of God
The immortality of the soul
The highest good is eternal life
The basic laws of morality
Aristotle on divine knowledge
God is a perfect knower.
God can only perfect things
There are no perfect things below the
orbit of the moon.
Therefore, God cannot know anything below
the orbit of the moon.
Aquinas responses
I. God know himself
God is the first cause of the cosmos
God knows himself as first cause.
If one knows the cause, one must know the
effect. The mover analogy
II. Gods own ideas are the prototypes
for creation; therefore, by knowing them, God also knows creation.
A critics response
In response to II, if God knows the
prototypes, then God knows only their essence not their full existence.
Humanity itself, not particular human beings.
Following upon this conclusion, the mover
analogy fails because would you trust a moving company that could only move
things according to tables and chair but not your tables and chairs?
Aquinas: Five Ways to Prove Gods
Existence
The Argument from motion:
There is motion in the universe--movers
moving things that in turn are moved by other movers.
There cannot be an infinite regress of
movers.
Therefore, there must be an unmoved mover
(=God), the cause of all movement.
The argument from efficient cause
There are effects in the universe that
are caused by causes that are effects of other causes.
There cannot be an infinite regress of
causes.
Therefore, there must be a first cause
(=God) that remains uncaused.
Contingent vs. necessary things
A contingent thing is one that is
A necessary thing is one that is
A substance is a
The argument from
contingency
There are contingent things.
Contingent things require a
non-contingent, necessary thing for their existence.
Therefore, a necessary thing (God) must
exist.
The argument from morality
Comparative moral judgments are made--the
good, the better, the best.
Such judgments are intelligible only on
the basis of a moral standard that embodies the best.
Therefore, such a moral standard (=God)
exists.
Note the Platonic idea that the highest
reality is also the highest good.
The argument from design
There is order and structure in the
universe.
Such order requires a cosmic ordering
agent.
Therefore, there must be such an agent.
No other word describe such an agent
except God.
Aquinas on Revealed Theology
Basic Articles of Faith:
Incarnation:
Trinity:
Creation out of nothing
Beatific Vision of God
Certainty of individual redemption
Rational vs. Theological Eudaimonism
Both Aristotle and Aquinas agreed that
Rational Eudaimonism:
Aquinas rejected Aristotles
Theological Eudaimonism:
The Overendowment Thesis
Premise: there are ways in which all
natural appetites are fulfilled in some fashion.
It is inconceivable to me that nature
should have endowed us with a set of appetites if there were no ways for them to
be satisfied. If our hunger for eternity--the deepest hunger of all--should
turn out to be the one hunger for which there is no satisfaction, it would be a
cruel trick."
Aquinas argument
Humans have a natural desire for perfect
happiness.
It is impossible for a natural desire to
be empty and vain. (Even animals have their natural desires fulfilled.)
The desire for perfect happiness cannot
be fulfilled in this life.
Therefore, it must be fulfilled after
this life.
The Argument from Analogy

Was Jesus a theological eudaimonist?
An ethics of love:
You should love your neighbor as
yourself.
You should love your enemies.
You should lay down your live for
another.
Greek concepts of love:
eros.
philia.
Theological Agapeism
Jesus used the word agape:
Christians must be self-sacrificing and
Christ-like,
Eudaimonists have confused
Must avoid a barter system of ethics.
Theological vs. Rational Agapeism
Rational Agapeism:
Michael Scriven: if it is one-on-one,
then one counts the value of the person. If there are more than two people, all
persons then count as equal.
If Martha can save the lives of two
people only by sacrificing her life, then she is morally required to.
Scrivens proof
Selfish society subjected to a
series of natural catastrophes
Three soldiers from this society
in a fox hole
Altruistic society subjected to
the same calamities.
Three soldiers from this society
in a fox hole
Determinism vs. free-will
Scientific determinism:
No thing is a cause of itself, such as
the human will.
Humans have no free-will and
Does divine power and determinism
undermine human freedom?
Three Types of Divine Power
DP 1:
Martin Luther rejects free-will.
John Calvin and predestination.
Luther:
Delegating divine power
DP 2:
God reserves veto power for
Aquinas and most contemporary Christian
philosophers.
A critique of DP2
Are science and morality properly
supported under DP2?
Not if free-will requires a power truly
our own.
And not if science and its laws require
immunity from divine intervention.
Divine Persuasion
DP3:
God has no veto power.
Full autonomy for both moral agents and
the laws of nature.
Process and feminist theologians. A truly
humanist theology?
What is a proposition?
Proposition
Statement in ordinary language.
The house is red
Analytic propositions
Aquinas calls them self-evident.
All circles are round
All triangles have three sides
All squares have four sides
All bachelors are unmarried males
A test for analyticity
Use the law of contradiction by negating
the predicate.
All circles are NOT round.
All triangles are NOT three-sided.
All squares are NOT four-sided.
All bachelors are NOT married.
Reductio ad absurdum.
The original statements are necessarily true.
Synthetic propositions
The truth of synthetic propositions are

Aquinas Proof: Short Form

kill!
Thou shalt kill!
Thou shalt steal!
Thou shalt commit adultery!

Aquinas agrees in Ro. 2:14-15.
Aquinas Intentionism

Consequentialism:
Proof of Intentionism:
Proof of Consequentialism:
The Doctrine of Double Effect (DDE)
The meaning of double:
.
Note: Aquinas explicitly rejects the
assumptions of this theory. Therefore, it is not his theory.
Four Criteria for DDE
The action in itself must be good.
The agent must intend only the good
effect and not the evil effect. The evil effect is foreseen, not intended.
The evil effect cannot be a means to the
good effect.
There must be a favorable balance between
the good and evil effects of the action.
Fourth criteria added in 19th Century.
Any problems with it?
Actions allowed by DDE
One may use medication to save pregnant
mother's life, even if it is known to produce miscarriages.
One may remove the cancerous womb of a
pregnant woman because of same reason.
One may draw off amniotic fluid if the
intention is to save the mother's life.
If the fertilized egg implants itself
outside the uterus (an "ectopic" pregnancy), then it can be removed surgically.
But fetal craniotomy is not permissible?
