Causality, pantheism, and deism
Agere sequitur esse (“action follows being” or “activity follows existence”) is a basic principle of Scholastic metaphysics. The idea is that the way a thing acts or behaves reflects what it is. But suppose that a thing doesn’t truly act or behave at all. Would it not follow, given the principle in question, that it does not truly exist? That would be too quick. After all, a thing might be capable of acting even if it is not in fact doing so. (For example, you are capable of leaving this page and reading some other website instead, even if you do not in fact do so.) That would seem enough to ensure existence. A thing could hardly be said to have a capacity if it didn’t exist. But suppose something lacks even the capacity for acting or behaving. Would it not follow in that case that it does not truly exist?

Martin and Murray on essence and existence
The real distinction between a thing’s essence and its existence is a key Thomistic metaphysical thesis, which I defend at length in Scholastic Metaphysics, at pp. 241-56. The thesis is crucial to Aquinas’s argument for God’s existence in De Ente et Essentia, which is the subject of an eagerly awaited forthcoming book by Gaven Kerr. (HT: Irish Thomist) One well-known argument for the distinction is that you can know thing’s essence without knowing whether or not it exists, in which case its existence must be distinct from its essence. (Again, see Scholastic Metaphysics for defense of this argument.) In his essay “How to Win Essence Back from Essentialists,” David Oderberg suggests that the argument can be run in the other direction as well: “[I]t is possible to know that a thing exists without knowing what kind of thing it is. (Such is our normal way of acquiring knowledge of the world.)” (p. 39)
Which brings
to mind this old Saturday Night Live

Knowing an ape from Adam
On questions
about biological evolution, both the Magisterium of the Catholic Church and
Thomist philosophers and theologians have tended carefully to steer a middle
course. On the one hand, they have
allowed that a fairly wide range of biological phenomena may in principle be
susceptible of evolutionary explanation, consistent with Catholic doctrine and
Thomistic metaphysics. On the other hand,
they have also insisted, on philosophical and theological grounds, that not every biological phenomenon can be given
an evolutionary explanation, and they refuse to issue a “blank check” to a
purely naturalistic construal of evolution.
Evolutionary explanations are invariably a mixture of empirical and
philosophical considerations. Properly
to be understood, the empirical considerations have to be situated within a
sound metaphysics and philosophy of nature.

Causality and radioactive decay
At the
Catholic blog Vox Nova, mathematics
professor David Cruz-Uribe writes:
I… am currently working through the
metaphysics of St. Thomas Aquinas as part of his proofs of the existence of
God… [S]ome possibly naive counter-examples from quantum mechanics come to
mind. For instance, discussing the principle that nothing can change
without being affected externally, I immediately thought of the spontaneous
decay of atoms and even of particles (e.g., so-called proton decay).
This might be a very naive question:
my knowledge of quantum mechanics is rusty and probably out of date, and I know
much, much less about scholastic metaphysics. So can any of our readers
point me to some useful references on this specific topic?

Working the net
The Daily Beast nominates
Aristotle for a posthumous Nobel prize.
(Even Aristotle’s mistakes are interesting: Next time you see a European
bison, you might not want to stand behind it.
Just in case.)

Progressive dematerialization
In the
Aristotelian-Thomistic (A-T) tradition, it is the intellect, rather than
sentience, that marks the divide between the corporeal and the
incorporeal. Hence A-T arguments against
materialist theories of the mind tend to focus on conceptual thought rather
than qualia (i.e. the subjective or “first-person” features of a conscious
experience, such as the way red looks or the way pain feels) as that aspect of
the mind which cannot in principle be reduced to brain activity or the like. Yet Thomistic writers also often speak even
of perceptual experience (and not just of abstract thought) as involving an
immaterial element. And they need not
deny that qualia-oriented arguments like the “zombie
argument,” Frank Jackson’s “knowledge
argument,” Thomas Nagel’s “bat
argument,” etc. draw blood against materialism. So what exactly is going on here?

Interview with the metaphysician
Recently I
was interviewed by two different websites about Scholastic
Metaphysics: A Contemporary Introduction. Both interviews have now been posted. The
first interview is at Thomistica.net,
where the interviewer was Joe Trabbic.
The second interview is at Strange
Notions, where the interviewer was Brandon Vogt. The websites’ respective audiences are very
different, as were the questions, so there isn’t any significant overlap
between the two interviews.

Augustine on the immateriality of the mind
In Book 10,
Chapter 10 of On the Trinity, St.
Augustine argues for the immateriality of the mind. You can find an older translation of the
work online, but I’ll quote the passages I want to discuss from the
McKenna translation as edited by Gareth Matthews. Here they are:
[E]very mind knows and is certain
concerning itself. For men have doubted
whether the power to live, to remember, to understand, to will, to think, to
know, and to judge is due to air, to fire, or to the brain, or to the blood,
or to atoms… or whether the combining or the orderly arrangement of the flesh
is capable of producing these effects; one has tried to maintain this opinion,
another that opinion.
On the other hand who would doubt
that he lives, remembers, understands, wills, thinks, knows, and judges? For even if he doubts, he lives; if he doubts,
he remembers why he doubts; if he doubts, he understands that he doubts; if he
doubts, he wishes to be certain; if he doubts, he thinks; if he doubts, he knows
that he does not know; if he doubts, he judges that he ought not to consent
rashly. Whoever then doubts about
anything else ought never to doubt about all of these; for if they were not, he
would be unable to doubt about anything at all…

DSPT symposium papers online (Updated)
Last week’s
symposium at the Dominican School of Philosophy
and Theology in Berkeley was on Fr. Anselm Ramelow’s anthology God,
Reason and Reality. Some of the
papers from the symposium are
now available online. In my paper, “Remarks on God, Reason and Reality,” I comment
on two essays in the anthology: Fr. Ramelow’s essay on God and miracles, and
Fr. Michael Dodds’ essay on God and the nature of life. Fr. Ramelow’s symposium paper is “Three Tensions
Concerning Miracles: A Response to Edward Feser.”
UPDATE 11/16: Fr. Dodds' paper "The God of Life: Response to Edward Feser" has now been posted at the DSPT website. Also, a YouTube video of all the talks and of the Q & A that followed has been posted.

DSPT interviews (Updated)
Back from another
very pleasant and profitable visit to the Dominican School of Philosophy
and Theology in Berkeley. Many thanks to
my hosts and to everyone who attended the symposium. The DSPT has just posted video interviews of
some of the participants in the July
conference on philosophy and theology.
John Searle, Linda Zagzebski, John O’Callaghan, and I are the interviewees. You can find them here
at YouTube.
Update 11/14: The DSPT will be adding new video clips weekly to its YouTube playlist. This week an interview with Fred Freddoso has been added.

Walking the web
Bishop
Athanasius Schneider is interviewed about the
recent Synod on the Family. On the
now notorious interim report: “This document will remain for the future
generations and for the historians a black mark which has stained the honour of
the Apostolic See.” (HT: Rorate

Meanwhile,
as Rusty

Dreher report, other Catholics evidently prefer the Zeitgeist to the Heilige Geist.
Scientia Salon on everything
you know about Aristotle that isn’t so.
Choice line: “While [Bertrand] Russell castigates Aristotle for not
counting his wives’ teeth, it does not appear to have occurred to Russell to
verify his own statement by going to the bookshelf and reading what Aristotle
actually wrote.”

Voluntarism and PSR
Aquinas
holds that “will follows upon intellect” (Summa
Theologiae I.19.1). He means in part
that anything with an intellect has a will as well, but also that intellect is
metaphysically prior to will. Will is
the power to be drawn toward what the intellect apprehends to be good, or away
from what it apprehends to be bad.
Intellect is “in the driver’s seat,” then. This is a view known as intellectualism, and it is to be contrasted with voluntarism, which makes will prior to
intellect, and is associated with Scotus and Ockham. To oversimplify, you might say that for the
intellectualist, we are essentially intellects which have wills, whereas the
voluntarist tendency is to regard us as essentially wills which have
intellects.

Nudge nudge, wink wink
Suppose you
go out on a blind date and a friend asks you how it went. You pause and then answer flatly, with a
slight smirk: “Well, I liked the restaurant.”
There is nothing in the literal meaning of the sentence you’ve uttered,
considered all by itself, that states or implies anything negative about the
person you went out with, or indeed anything at all about the person. Still, given the context, you’ve said
something insulting. You’ve “sent the
message” that you liked the restaurant but not
the person. Or suppose you show someone
a painting and when asked what he thinks, he responds: “I like the frame.” The sentence by itself doesn’t imply that the painting is bad, but the overall
speech act certainly conveys that message all the same. Each of these is an example of what H. P.
Grice famously called an implicature, and they
illustrate how what a speaker says in
a communicative act ought not to be confused with what his words mean.
Obviously there is a relationship between the two, but they are not
always identical.

Could a theist deny PSR?
We’ve
been talking about the principle of sufficient reason (PSR). It plays a key role in some arguments for the
existence of God, which naturally gives the atheist a motivation to deny
it. But there are also theists who deny
it. Is this a coherent position? I’m not asking whether a theist could
coherently reject some versions of
PSR. Of course a theist could do
so. I
reject some versions of PSR. But could a
theist reject all versions? Could a
theist reject PSR as such? Suppose that
any version of PSR worthy of the name must entail that there are no “brute facts” -- no facts
that are in principle unintelligible,
no facts for which there is not even in
principle an explanation. (The “in
principle” here is important -- that there might be facts that our minds happen to be too limited to
grasp is not in question.) Could a
theist coherently deny that?

Della Rocca on PSR
The principle
of sufficient reason (PSR), in a typical Neo-Scholastic formulation, states
that “there is a sufficient reason or adequate necessary objective explanation
for the being of whatever is and for all attributes of any being” (Bernard
Wuellner, Dictionary
of Scholastic Philosophy, p. 15).
I discuss and defend PSR at some length in Scholastic
Metaphysics (see especially pp. 107-8 and 137-46). Prof. Michael Della Rocca
defends the principle in his excellent article “PSR,”
which appeared in Philosopher’s Imprint
in 2010 but which (I’m embarrassed to say) I only came across the other day.
Among the arguments for PSR I put forward in Scholastic Metaphysics are a retorsion argument to the effect that if PSR were false, we could have no reason to trust the deliverances of our cognitive faculties, including any grounds we might have for doubting or denying PSR; and an argument to the effect that a critic of PSR cannot coherently accept even the scientific explanations he does accept, unless he acknowledges that there are no brute facts and thus that PSR is true. Della Rocca’s argument bears a family resemblance to this second line of argument.

Meta-comedy
While we’re on
the subject of Steve Martin, consider the following passage from his memoir
Born
Standing Up. Martin recounts the
insight that played a key role in his novel approach to doing stand-up comedy:
In a college psychology class, I had
read a treatise on comedy explaining that a laugh was formed when the
storyteller created tension, then, with the punch line, released it... With
conventional joke telling, there's a moment when the comedian delivers the
punch line, and the audience knows it's the punch line, and their response
ranges from polite to uproarious. What
bothered me about this formula was the nature of the laugh it inspired, a vocal
acknowledgment that a joke had been told, like automatic applause at the end of
a song...

Thomas Aquinas, Henry Adams, Steve Martin
In his conceptual
travelogue Mont-Saint-Michel
and Chartres -- first distributed
privately in 1904, then published in 1913 -- historian Henry Adams devoted a
chapter to Thomas Aquinas. There are oversimplifications
and mistakes in it of the sort one would expect from a non-philosopher
interested in putting together a compelling narrative, but some interesting
things too. Adams rightly emphasizes how
deep and consequential is the difference between Aquinas’s view that knowledge
of God starts with sensory experience of the natural order, and the tendency of
mystics and Cartesians to look instead within the human mind itself to begin
the ascent to God. And he rightly notes
how important, and also contrary to other prominent theological tendencies, is Aquinas’s
affirmation of the material world. (This
is a major theme in Denys
Turner’s recent book on Aquinas, about which I’ve been meaning to
blog.) On the other hand, what Adams
says about Aquinas and secondary causality is not only wrong but bizarre.
