A. Part I: Reason,
Science, and Religion
- 1.
Introductory remarks
- Literary genre: Who speaks for Hume?
- Philo's strategy: play Demea and Cleanthes off against
one
another
- Three realms:
- Common life and experience
- Natural science
- Metaphysics (including natural theology)
- 2. Demea and
Philo: Pessimism about natural
reason (aka skepticism)
- Read from pp. 3-5 as Philo explains why a two-course
philosophy requirement is a really bad thing.
- 3. Cleanthes:
Optimism about natural reason
- Read from pp. 5-6 as Cleanthes explains why skeptics
are
laughable:
"What will it be, the door or the second-story window? Either way, you
lose. Sure, we can work ourselves up into a skeptical frenzy, but it
can't last very long. Furthermore, how can you doubt the great advances
made in recent science, e.g., Newton's analysis of the rainbow? And yet
this science is no less subtle, no less abstract, no less esoteric than
natural theology. (And, surely, you do not want to align yourself with
those who reject subtle reasoning of any sort and then embrace 'the
most absurd tenets which a traditional superstition has recommended to
them'.)"
Note in passing Cleanthes's invocation of John Locke's principle that
we ought always to proportion our assent to the evidence. Is this
principle compatible with Christian faith or any other that reveres its
martyrs?
In reply Philo implicitly distinguishes two kinds of skepticism -- one
good, the other bad -- and two ways of thinking about natural
science -- one of which is just an extension of "animal faith," the
other of which is open to theoretical skepticism.
4. Reason and "animal
faith": two kinds of
skepticism
- Metaphysical or speculative
skepticism:
- Reason cannot give a theoretical or speculative
demonstration of any important metaphysical or moral thesis -- or of
any
common sense belief, for that matter. On Philo's view this sort of
skepticism is true, but, lucky for us, we have good enough cognitive
and affective "animal instincts" to help us get by in the
ordinary affairs of life.
- Moral or practical
skepticism:
- The resolve to snuff out any "animal faith" that
leads us
to accept as practically certain what cannot be demonstrated by
speculative reason. This would indeed be dangerous, but is not at all
what Philo (or Demea, for that matter) is recommending.
5. Two views
of natural science
- Accepting a scientific theory involves believing with
a high
degree of certitude that the unobservable structure of reality is as
the theory says it is -- the aim of natural science is to get
to real
causes
- Accepting a scientific theory should involve believing
only
that the theory is an accurate guide to what is observable and what
will be observable in the future --the aim of natural
science
is just
to order our experience and not to get to real
causes
- We can bring these last two sections (4 and 5)
together as
follows:
Let
(i) = common life and experience
(iia) = natural science with respect to its empirical part, where it is
simply common life and experience writ large
(iib) = natural science with respect to its speculative (theoretical)
part
(iii) = metaphysics, including natural theology
Then,
- according to Philo, we have animal
faith
regarding (i) and (iia), but no speculative certitude
with
respect to any of (i), (iia), (iib), or (iii). On this view, we are
best off never having troubled our minds with philosophical inquiry.
(The combination of (1) deep pessimism with respect to natural reason
and (2) the abandonment of the search for wisdom as beyond our
capabilities is sometimes called pragmatism,
whereas the
combination of (1) deep pessimism with respect to natural reason and
(2) firm belief in revealed religion is sometimes called fideism.
At this point Philo could go either way.)
- according to Cleanthes, since we
have speculative
certitude with respect to (iib), there is no reason in
principle
why we can't have speculative certitude regarding
(iii) in at
least some of its parts
B. Parts II-V: The
Argument from Design
- 1. Obscurantism
asserted by Demea and
Philo [previously intimated on pp. 4, 7, & 8].
- 2. The argument
(1) The universe resembles the productions or effects of human
intelligence. [premise]
(2) Similar effects proceed from similar causes. [premise]
(3) So the universe is the production or effect of some intelligent
being. [from (1) and (2)]
(4) But the universe is much more complex than any production of human
intelligence. [premise]
(5) So the production of the universe required an intelligence much
greater than human intelligence. [from (2) and (4)]
Therefore, there is a designer of the universe whose
intelligence far surpasses ours. [from (2) and (5)]
- 3. First-level
objections and replies
These objections are aimed at (1), the application of (2) to the
present case, and the inference from (1) and (2) to (3).
- OBJECTIONS:
- Objection 1: The analogy between
the universe and
human artifacts is weak. [pp. 16-18]
- Objection 2: Intelligence is
only one of the
active causes in the world. [p. 19]
- Objection 3: Even if
intelligence is everywhere
operative now, we cannot properly ascribe it to the
origins
of the universe. [p. 20]
- Objection 4: The origin of the
universe is a
single unique case and so analogies are pointless. [p. 21]
- REPLIES:
Note: The general form of Cleanthes's replies is to show that Philo's
objections prove too much, since exactly the same objections could be
proposed even with regard to effects that no sane person would deny
have an intelligent cause. So since no one would take Philo's objection
seriously in these cases, neither should they take them seriously in
the case at hand.
- Reply to 1: The voice in the
clouds [pp. 23-24]
- Reply to 2: The vegetating
library [p. 25]
- Reply to 3: The eye [p. 25]
- 4.
Second-level objections: metaphysical
attributes
Here the objections accept the conclusion of the argument, but argue
that the being whose existence is proved is either incomprehensible or
finite.
- Anthropomorphism vs. Obscurantism (Mysticism) [pp.
28-29]
- The fruits of anthropomorphism: A FINITE GOD
The big objection: In the absence of an
independent
argument for the designer's perfection, the design argument does not
necessarily yield -- nor does Cleanthes want it to (p. 29) -- a being
who is infinite in perfection (or
power or
knowledge or goodness, etc.) or indefectible or one
or eternal
or necessary or incorporeal
..............
C. Parts IX-XI: The
Metaphysical (A Priori)
Argument
- 1. The argument
(1) For any contingent being x, x's
existing requires a
causal explanation that is ultimate.
(2) To attribute x's existing to a,
b, c
.... is not ultimate if each of a, b,
c .... is
itself a contingent being.
[For in that case the composite fact of a's existing and b's
existing and c's existing itself requires an explanation.]
(3) So any ultimate explanation of x's existing
must invoke the
existence of a being whose own existence neither requires nor admits of
a causal explanation.
(4) Every being in the material universe is contingent, and every
temporal being is contingent, and every composite being is contingent
Therefore, there is an immaterial, eternal, and
non-composite being that is the cause of existence for every contingent
being
- 2. Objections
and Replies
- OBJECTIONS:
- Objection 1: The being in
question can be
conceived not to exist (p. 55).
- Objection 2: Why can't matter
be the
being in question? (p. 56)
- Objection 3: An explanation for
each element
of a series just is an ultimate explanation for the
whole
series (p. 56).
- Objection 4: Why not several
necessary
beings?
- Objection 5: The argument does
not inspire a
movement to piety (p. 57).
- REPLIES:
- Reply to 1: Can it really? In
any case, what's
conceivable or imaginable need not be metaphysically possible.
- Reply to 2: A separate argument
must be given
to rule out this possibility. (Recall St. Thomas's natural
theology.)
- Reply to 3: This is not at all
obvious once I
ask why there is something (contingent) rather than nothing.
- Reply to 4: Same as reply to 2,
including
parenthetical remark
- Reply to 5: Why think that this
is a criterion
for the success of the argument?
- 3. God's moral attributes and evil: Exit Demea
- Is pessimism with respect to the human condition the
friend or foe of religion? [Part X: Demea vs Cleanthes]
- Is the mere existence of evil compatible with the
existence of an all-knowing, all-powerful, and perfectly good God?
Philo in the end admits that there is no incompatibility, but the point
that he's really after is that, given our epistemic position,
the
existence of evil makes the thesis that there is an all-knowing,
all-powerful, and perfectly good God less probable than its contrary.
(This becomes clear at the beginning of Part XI.)
- The visitor from another world (Part XI): two possible
starting points
- antecedent belief in a perfect creator
- antecedent neutrality with respect to the existence of
a perfect creator
- QUESTION:
WHICH STARTING POINT IS OURS?
- Four puzzles about the world (in effect, Philo is
pointing out why, with sufficient power, he could have done a much
better job creating and governing the world than God is reputed to have
done):
- Why any pain at all?
- Why govern in accord with general laws that are
beneficial to species but not to individuals?
- Why such skimpiness in the allocation of powers to
creatures?
- Why so many defects in workmanship?
- Four hypotheses (p. 75): The first causes are either
- all good (Christian view) or
- all malevolent or
- some good and some malevolent (cosmological dualism of a Manichean sort) or
- indifferent (the view of the Epicureans)
- A surprising possibility: Is Christianity as a whole
easier to defend than classical theism, which is a proper part of it?
(St. Francis and the contemporary problem of understanding him.)
D. Part XII: Religion
and Society
- 1. Cleanthes: religion as a positive influence
- Fear of eternal punishment and hope for eternal reward
[p. 82].
- Consolation in the midst of suffering and in the face of
death [p. 86]. The alternative is a sort of default Epicureanism
that sees great pain and suffering as meaningless and that, in the
face of death and without hope of immortality, recommends striving for
a "comfortable" existence until one dies. One could argue that
such a view leads to excessive individualism and weakens one's desire
to make sacrifices for others.
CONCLUSION: Religion, however much corrupted, is an
important positive influence in society. So the disagreements between
believers and skeptics are not merely verbal. There is potentially a
big difference between the sort of social conditions produced by
religious faith, on the one hand, and by religious skepticism, on the
other.
- 2. Philo: religion as a baneful influence
- Eternal reward and punishment hold sway only over those
who are willing to sacrifice "natural virtue" for fanaticism [pp. 83-85]
- Religion is too morbid to hold sway over common
people -- devout people are "gloomy and melancholic." [p. 87] And
when Philo points out that the tenets of morality often diverge from
the demands of one's religious philosophy, it must be said that in
certain Protestant understandings of atonement there is a very unclear
connection between being saved and being morally upright. This is what
Philo is talking about here.
- Notice
that Philo's position is based on the assumption that human beings have
preponderant "natural motives of justice and humanity" (p. 84) and that
it is these benevolent "natural motives" that tend to be corrupted by
religion. From a Christian perspective this constitutes an
outright denial of the doctrines of original sin and of the
consequences of original sin (disordered sentient desire, ignorance,
weakness, and malice). Moreover, even non-Christian classical
moral philosophies of the sort propounded by Plato, Aristotle, the
Stoics and even the Epicureans begin from the assumption that our souls
are disordered from the beginning and that we need to work hard to make
our motives benevolent and other-directed. Also, there is an
interesting contrast here between Philo's views and those of Alexis de
Tocqueville in his Democracy in America.
CONCLUSION: Since religion is always found in a corrupted
state, society is better off without it.
- 3. Reprise: skepticism and faith
- Religious skeptics as the favorites of God after
philosophical theists [p. 86]
- Skepticism as a prelude to accepting Christian revelation
[p. 89]
