Aristotelians ought to be presentists

Presentism holds that within the temporal domain, only the present exists and the past and future do not.  Alex Pruss thinks that Aristotelians shouldn’t be presentists.  That would be news to Aristotle, Aquinas, and other presentist Aristotelians.  I agree with them rather than with Alex, and I think that presentism is in fact the natural view to take if one starts with an Aristotelian view of the nature of physical reality, and of the nature of time in particular.  I spell all this out at length in Aristotle’s Revenge.  Here I will just try briefly to convey the general idea.

Vallicella on existence-entailing relations and presentism

Bill Vallicella continues his critical response to my defense of presentism in Aristotle’s Revenge.  In the first part of his critique (to which I responded in an earlier post), Bill raised the influential “truthmaker objection” against presentism.  In his latest post, he rehearses another popular objection, which appeals to the nature of relations.  I don’t think this objection is any more formidable than the truthmaker objection, but here too Bill disagrees.

Vallicella on the truthmaker objection against presentism

Among the many ideas defended in Aristotle’s Revenge is the A-theory of time, and presentism in particular.  Relativity, time travel, the experience of time, and other issues in the philosophy of time are treated along the way, and what I say about those topics is crucial to my defense of presentism.  (See pp. 233-303.)  My buddy Bill Vallicella objects to my response in the book to the “truthmaker objection” against presentism.  Let’s consider Bill’s misgivings.

Presentism is the thesis that only the present exists, and that past and future events and objects do not.  To be more precise, it is the thesis that in the temporal realm, only present objects and events exist.  (For one could also hold – as I do, though other presentists might not – that in addition to what exists in time, there is what exists in an eternal or timeless way and what exists in an aeviternal way.) 

Review of a new volume on Neo-Scholasticism

My review of Rajesh Heynickx and Stéphane Symons’ anthology So What's New About Scholasticism? How Neo-Thomism Helped Shape the Twentieth Century appears at Notre Dame Philosophical Reviews.

Can you doubt that 2 + 3 = 5?

In his first Meditation, Descartes famously tries to push doubt as far as he can, in the hope of finding something that cannot be doubted and will thus provide a suitable foundation for the reconstruction of human knowledge.  Given the possibility that he is dreaming or that an evil spirit might be causing him to hallucinate, he judges that whatever the senses tell him might in principle be false.  In particular, the entire material world, including even his own body and brain, might be illusory.  Hence claims about the material world, and empirical claims in general, cannot in Descartes’ view be among the foundations of knowledge.

Artificial intelligence and magical thinking

Arthur C. Clarke famously said that “any sufficiently advanced technology is indistinguishable from magic.”  Is this true?  That depends on what you mean by “indistinguishable from.”  The phrase could be given either an epistemological reading or a metaphysical one.  On the former reading, what the thesis is saying is that if a technology is sufficiently advanced, you would not be able to know from examining it that it is not magic, even though in fact it is not.  This is no doubt what Clarke himself meant, and it is plausible enough, if only because the word “sufficiently” makes it hard to falsify.  If there was some technology that almost seemed like magic but could be shown not to be on close inspection, we could always say “Ah, but that’s only because it wasn’t sufficiently advanced.”  So the thesis really just amounts to the claim that people can be fooled into thinking that something is magic if we’re clever enough.  Well, OK.  I don’t know how interesting that is, but it seems true enough.

New volume on philosophers and Catholicism

Faith and Reason: Philosophers Explain Their Turn to Catholicism, an anthology edited by Brian Besong and Jonathan Fuqua, will be out next month.  You can pre-order at Amazon.  My essay “The God of a Philosopher” appears in the volume, and recounts how I came to reject atheism for Catholicism, specifically (rather than some other religion or a purely philosophical theism).  Other contributors to the volume include Peter Kreeft, J. Budziszewski, Candace Vogler, Robert Koons, Francis Beckwith, and several other philosophers.

Five Proofs on radio

Recently, John DeRosa interviewed me for the Classical Theism Podcast.  You can listen to the interview here.  We discuss my book Five Proofs of the Existence of God and Simon Blackburn’s criticisms of it, my conversion to Catholicism, my new book Aristotle’s Revenge, and other matters.  If you listen all the way to the end of the interview, John explains how you can enter to win a free copy of Aristotle's Revenge.

Wrath darkens the mind

A straw man fallacy is committed when you attack a caricature of what your opponent has said rather than addressing his actual views.  Hypocrisy involves blithely doing something that you admit is wrong and criticize in others.  But what do you call it when you bitterly criticize someone else for doing something you approve of and praise in yourself and others?  I don’t know if there’s a label for that.  “Being an unhinged weirdo” is about the best I can come up with, and I’ve got a couple of examples.

2019 Aquinas Lecture

In January I gave the 2019 Aquinas Lecture at the University of St. Thomas in Houston, on the theme “Classical Theism and the Nature of God.”  Before the lecture I was kindly awarded the Order of St. Thomas Medal by the Center for Thomistic Studies.  You can watch the video of the lecture at the CTS website.  (Click on the “Aquinas Lecture Series Videos” link.)  That’s the medal you’ll see me wearing.  The waiter joke at the beginning makes reference to something said in Steve Jensen’s opening remarks, which are not in the video.

ORDER NOW: Aristotle’s Revenge (Updated)

UPDATE 3/9: A reader points out that another option, for readers anywhere in the world, is to order through Book Depository.  You can now also order through Barnes and Noble.  The other options, to remind you, are Amazon.com and Casemate Academic (for U.S. orders) and Eurospan, Amazon.co.uk, and Amazon's other European sites (for European orders).
  
UPDATE 3/7: At the moment, Amazon is accepting pre-orders again.  These things tend to fluctuate, so check back periodically if the pre-order option temporarily disappears again.  As noted below, you can also pre-order through the U.S. distributor.  European readers can also order through Eurospan.

UPDATE 3/5: Looks like Amazon's pre-order stock sold out right away.  If you don't want to wait for Amazon to re-stock, it looks like you can also pre-order via the U.S. distributor.

Amazon has the U.S. release of my new book Aristotle’s Revenge: The Metaphysical Foundations of Physical and Biological Science scheduled for March 22.  You can pre-order now.  The book has already been available for a few weeks at Amazon.co.uk and other European outlets.   

Some pre-publication reactions to the book:

Byrne on gender identity

What is it to have a “gender identity”?  At Arc Digital, Alex Byrne examines some proposed definitions of the concept and common assumptions about it, and finds them problematic.  In earlier posts, we looked at Byrne’s views about whether sex is binary and whether sex is socially constructed.  As his earlier articles did, Byrne’s latest piece brings the cold shower of sober philosophical analysis to a discussion that is usually overheated and muddleheaded.

Surfing the web

At First Things, R. R. Reno concludes that Francis’s papacy is failing.  Cardinal Gerhard Müller issues a “manifesto of faith” to address the current theological crisis.  Meanwhile, Robert Fastiggi buries his head deeper into the sand.  (And wastes his time.  I already refuted Fastiggi’s position months ago.)

Jeremy Butterfield reviews Sabine Hossenfelder’s Lost in Math and Hossenfelder responds.  A review by Donald Devine at The Imaginative Conservative. 

Magician and actor Ricky Jay has died.  Reminiscences at The Federalist, Vulture, and NPR.  A personal remembrance by Jay’s friend David Mamet.

In the Harvard Journal of Law and Public Policy, Ryan Proctor argues that Catholic judges are not obligated to recuse themselves in capital cases.

Abortion and culpability

Yesterday at The Corner, Ramesh Ponnuru responded to a reader who criticizes opponents of abortion who express special outrage at late-term abortions.  If all direct abortion amounts to murder, the reader says, then it is only a cynical political tactic to speak of late-term abortions as if they were especially odious.  I more or less agree with Ponnuru’s reply to this (give it a read, it’s brief), but I would add a clarification and a qualification.

The latest on Five Proofs

My book Five Proofs of the Existence of God is briefly reviewed by Christopher McCaffery in the March 2019 issue of First Things.  From the review:

Addressing contemporary and historical objections, Feser explains the logic of each proof with impressive clarity… Five Proofs is a useful resource for anyone seeking an introduction to historical arguments about God’s existence and their relationship to contemporary philosophical scholarship.

Socialism versus the family

Yesterday I gave a talk at the Heritage Foundation on the topic “Socialism versus the Family.”  You can watch the lecture on YouTube or at the Heritage website.

Adventures in the Old Atheism, Part III: Freud

Our sojourn among the Old Atheists was briefer than I’d intended.  To my great surprise, I see that the previous installment in this series dates from roughly the middle of 2016!  So let’s make a return visit.  Our theme has been the tendency of the best-known Old Atheists to show greater insight vis-à-vis the consequences of atheism than we find in their shallow New Atheist descendants.  This was true of Nietzsche and of Sartre, and it is true of Sigmund Freud.  So lay back on the couch and light up a cigar.  And before you start speculating about what hidden meaning lay behind my sudden return to this topic, remember: Sometimes a blog post is just a blog post.

Early 2019 speaking engagements

I recently got back from Blackfriars in Oxford, where I gave talks on classical theism and cooperation with evil.

This Thursday, January 31, I will be giving the 2019 Aquinas Lecture at the University of St. Thomas in Houston.  

On February 11, I will be speaking at the Heritage Foundation in Washington, D.C., on the topic of socialism versus the family.

The Bizarro world of left-wing politics

I have only a little to add to what others have already said about the Kafkaesque Covington affair.  There were, as you all know by now, three main parties involved.  There was the group led by Nathan Phillips, who is now known to be a liar and rabble rouser who appears to have been trying to provoke a confrontation.  There were the “Black Hebrew Israelites,” classified by the SPLC as a hate group and who have been captured on video instigating the whole mess by shouting things that any left-winger would normally denounce as the worst sort of racist, sexist, homophobic, and fundamentalist bigotry.  And there are the Covington Catholic school teenagers, who were there waiting for a bus and got caught in the middle of these two groups of lunatics. 

Washburn contra the “new natural lawyers”

I highly recommend theologian Christian Washburn’s excellent article “The New Natural Lawyers, Contraception, Capital Punishment, and the Infallibility of the Ordinary Magisterium,” from the latest issue of Logos.  Is there anything new to say about the “new natural law” (NNL) position on capital punishment?  There is, as Washburn shows.

Materialism subverts itself

A naïve understanding of materialism attributes to it a naïve understanding of matter.  Matter, common sense says, is more or less the way it appears to us in ordinary experience.  It is solid, colored stuff that always tastes, smells, sounds, and feels a certain way.  Materialism, on a naïve understanding, is the view that everything that exists is like that.  Even unobservable particles are assumed to be tiny solid, colored objects that have their own tastes, smells, sounds, and feels to them.  Like little stones or marbles.

Finnis on capital punishment (Updated)

John Finnis holds that the Catholic Church could reverse her traditional teaching that capital punishment can be legitimate in principle.  I criticized his position in the course of an exchange at Public Discourse several months ago.  Last month Finnis replied in an article at Public Discourse.  Today I respond to Finnis’s reply in an article at Catholic World Report.

Meanwhile, at Denver Journal, Ben Crenshaw kindly reviews By Man Shall His Blood Be Shed: A Catholic Defense of Capital Punishment.  From the review:

The sexual revolution devours its children

In two recent posts, we looked at philosopher Alex Byrne’s criticisms of claims made by some transgender activists to the effect that sex is not binary and that it is socially constructed.  Byrne is by no means the only philosopher alarmed at the increasingly bizarre claims being made by such activists – and the shrillness with which they are making them.  Kathleen Stock worries that such ideas will cause harm to women.  Daniel A. Kaufman warns that they threaten nothing less than the end of civil rights.  Nor are these philosophers conservatives who are hostile to the sexual revolution.  They are progressives concerned about extremism and anti-intellectualism in their own ranks.  And as if to prove the critics’ point, some of the activists have in response tried to get the critics fired and otherwise to silence them.

Christmas every day

A Protestant friend once asked me what the point is of the Catholic doctrine of transubstantiation.  Why is it so important to think that Christ is really present under the accidents of bread and wine?  What is the cash value of this idea?  The answer I gave him is best understood in light of the meaning of Christmas.

Christmas is about Emmanuel, God with us.  In particular, it is about the second Person of the Trinity entering the material world by taking on flesh.  He did so by entering into Mary’s womb, and that is why Mary had to be without sin, whether original or actual.  She was, in the most intimate way possible, the tabernacle of God.  And the tabernacle of God must be spotless. 

Immateriality in Rome

Earlier this month I gave a talk on “The Immateriality of the Intellect” at a conference on neuroscience and the soul held at the Angelicum in Rome.  Video of the talk has now been posted at YouTube.
