Oh joy!

Via Maverick Philosopher, I have just discovered the website of philosopher Andrew M. Bailey. Bailey is collecting all of the articles and book reviews of certain philosophers to make them available to everyone. One of his collections is nearly every publication of Alvin Plantinga. Another is the same of Peter van Inwagen. Another is David Lewis, which is exciting since I've always felt the need to have a more intimate knowledge of his philosophy. I might even put these links on the sidebar. So, much thanks to Bailey.

If you like cello, here's a couple of videos you can put on and play all day in the background. The first is the two-hour long complete collection of Bach's cello suites (which I've mentioned before here):

The second is the four-hour long complete collection of Vivaldi's cello concertos:

A great SF author you've never heard of

Grant Callin wrote a handful of short stories -- four in total -- and wrote a novel that functioned as a sequel to one of them. He then expanded the short story into a novel. That's the entirety of his output. All I've read are his two novels. Saturnalia, the expansion of the short story "Saturn Alia", and the sequel A Lion on Tharthee, which I don't like as much, but it is still extremely good. Saturnalia is basically a treasure hunt in the Saturn system. It's glorious. It is, to my mind, very reminiscent of Heinlein's style of writing in how readable and flowing the narrative is. Yet despite its readability, it is definitely hard science-fiction: Callin knows his stuff, and what he doesn't know, he fakes very well. Take this passage from the beginning of Saturnalia:

"Listen Whitey," he came back. "I'm a SpaceHome maintenance specialist -- been one for twenty-five years. And if there's one thing I've learned, it's to expect the unexpected. We been livin' up here for over fifty years now, and we're still learnin' about the environment -- cosmic burst anomalies, vacuum-induced bearing creep, lubricant outgassing, trapped corona discharge, and on and on. Every time we think we've got a problem licked and begin to start congratulating ourselves, it shows up again in a different form, and -- bingo! -- we got a new long-term environmental phenomenon to worry about."

That sounds absolutely real to me, real conditions of living in space. Callin's focus on technology (and piloting spacecraft) may not be everyone's cup of tea, but I enjoy it, and engineers (and pilots) should absolutely love it. The only weakness to both books is that they have too much bonhomme camaraderie. You know what I mean: the main characters are diamonds in the rough in some sense, and people are always able to see through the exterior and recognize how truly deep and noble they are. Heinlein does this too, but Callin's is so over the top that it gets distracting. Another minor weakness is that Lion on Tharthee begins with a clear statement of the myth of conflict between science and religion, but that's so common to science-fiction that you can't hold it against anyone (although more recent science-fiction writings seem to be correcting this misunderstanding). Regardless whatever weaknesses the books may have are very minor and are heavily outweighed by the positives. I strongly recommend these books to everyone who likes science-fiction.

Breaking News from the Outer Planets

1. Neptune has a new moon. Well, new to you. It was discovered by going over old photos from the Hubble Space Telescope. The moon is 12 miles, or 19 kilometers, wide. So think about that for a moment: a telescope in orbit around the earth was able to spot a 12 mile-wide object in orbit around Neptune.

2. Tomorrow, on July 19, the Cassini spacecraft in orbit around Saturn will turn its cameras inward and will take a picture of the earth. From Saturn. It will take the picture between approximately 2:27 and 2:42 Pacific time -- add three hours for the east coast, five more for Great Britain, and one more for continental Europe. So make sure to look up and smile. They've done this before. Here's one,

which is reminiscent of the "pale blue dot" picture that Carl Sagan talked NASA into taking from Voyager 1. Of course, Sagan used this to argue that the earth and humanity are insignificant and that this contradicts the traditional view of humanity as the pinnacle of creation supposedly taught in the Bible -- and I can't help but think he already had the book half written when he asked NASA to take the picture. Unfortunately for Sagan, we've known since at least Aristotle that in comparison to the size of the universe the earth is, for all practical purposes, infinitely small, a mathematical point with zero volume. For more on this, read "Copernicus and the Tale of the Pale Blue Dot" by Dennis Danielson.

Update (26 July): Here's the new picture of earth taken from Saturn:

and here's one taken at about the same time from the Messenger spacecraft in orbit around Mercury:

C.S. Lewis's Argument against Naturalism, part 1

The following series of posts are an adaptation of a thesis I wrote for one of my Master's degrees.

Introduction and Background
So many books have been written about C.S. Lewis, that there are actually books to simply catalogue them.{1} His influence, however, has been more on the popular level than in academia. This is largely Lewis’s doing: he wanted to write for the common man, the layperson, rather than the scholar. Unfortunately, the result of this has been that professional philosophers and theologians often do not treat him with the seriousness he deserves. Lewis, however, taught philosophy at Oxford in the beginning of his academic career,{2} surrounded himself with philosophers all his life,{3} and had “outstanding philosophical instincts.”{4} Thus, the first chapter of a recent philosophical book defending him is entitled, “Taking C.S. Lewis Seriously.”{5} One of the minor premises in this series of posts is to point to several examples where Lewis anticipates issues that have since come to the fore in analytic epistemology.

Initial statement of argument
One of Lewis’s arguments is that our reasoning capacities cannot be accounted for on naturalistic premises, and so we are forced by the fact that we reason to posit a supernaturalist worldview. His most extensive treatment of this argument is in his book Miracles, but he expressed it many times in his writings. For example:

We are certain that, in this life at any rate, thought is intimately connected with the brain. The theory that thought therefore is merely a movement in the brain is, in my opinion, nonsense, for if so, that theory itself would be merely a movement, an event among atoms, which may have speed and direction, but of which it would be meaningless to use the words “true” or “false.”{6}

Another example:

Unless we can be sure that reality in the remotest nebula or the remotest part obeys the thought laws of the human scientist here and now in his laboratory -- in other words, unless Reason is an absolute -- all [science] is in ruins. Yet those who ask me to believe this world picture also ask me to believe that Reason is simply the unforeseen and unintended by-product of mindless matter at one stage of its endless and aimless becoming. Here is flat contradiction. They ask me at the same moment to accept a conclusion and to discredit the only testimony on which that conclusion can be based.{7}

These two quotes succinctly express the three aspects of Lewis’s argument. First: if matter is all that exists, our beliefs are entirely caused by purely material processes, since there would be no other processes available to cause them. In which case, they are not the result of following the logic of an argument to a valid conclusion. As such, our beliefs are not logical or rational, and are therefore suspect -- including the belief that our beliefs are entirely caused by purely material processes. Materialism is therefore a self-refuting hypothesis: if it were true, we could have no reason for thinking it to be true.

Second: physical events are brute facts, and so it is nonsensical to call them true or false. A physical object is not “about” another physical object. Thoughts, on the other hand, are about things, and can be true or false. Therefore, our reasoning processes are more than physical events.

Third: the pattern our reasoning takes must also be the pattern by which physical reality acts. Lewis sees such a correspondence as enormously implausible on materialistic grounds. For random physical events to produce such a correspondence would be like an explosion producing order; not merely order, but information; not merely information, but information about itself.

Lewis’s argument is thus more modest than similar arguments from consciousness or “noölogical arguments.”{8} In fact, Lewis explicitly states that he is “not maintaining that consciousness as a whole must necessarily be put in the same position [as reason]. Pleasures, pains, fears, hopes, affections and mental images need not. No absurdity would follow from regarding them as parts of Nature.”{9}

Following John Beversluis and Victor Reppert -- a critic and an advocate respectively -- I will refer to this as the argument from reason.{10} This argument can be divided into two parts: the first half argues that nature by itself cannot account for human reason, and the second half argues that something other than nature must therefore be posited. While Lewis took the argument in a specifically theistic direction, he also suggested, “There are all sorts of different ways in which you can develop this position, either into an idealist metaphysic or a theology, into a theistic or a pantheistic or dualist theology.”{11} Because of this ambiguity, here I will only examine the first half of the argument, the refutation of ontological naturalism.

Christian philosopher G.E.M. Anscombe criticized Lewis’s argument at a meeting of the Socratic Club at Oxford in 1948,{12} and Lewis was forced to reformulate it in response to her objections. In this series of posts, I will look at Lewis’s original version of the argument, analyze Anscombe’s objections with the help of several philosophers who have commented on the exchange, and see whether Lewis’s reformulation holds up to scrutiny.

A note on terminology: Lewis originally presented the argument from reason by contrasting valid and invalid inferences, and then moved from this to refer to valid and invalid reasoning in general. Anscombe challenged his use of the terms “valid” and “invalid,” and Lewis, in his response at the Socratic Club,{13} conceded the point, and suggested the terms “veridical,” “verific,” or “veriferous” in its stead (the latter two being neologisms). I think the most appropriate terms for what Lewis is trying to say are “veracious” and “veracity.” Nevertheless, to avoid going back and forth between different terms at different stages of the argument (he also occasionally uses the term “sound”), I will simply employ “valid” and its derivatives throughout, unless a direct quote employs a different term.

Background and sources
Of course, this argument was not original to Lewis. Perhaps the earliest argument that there is something self-defeating about any kind of mechanism or determinism, whether materialistic or otherwise, was expressed by Epicurus when he wrote, “The man who says that all things come to pass by necessity cannot criticize one who denies that all things come to pass by necessity: for he admits that this too happens of necessity.”{14} Consequently, such arguments are sometimes called “Epicurean” arguments.{15}

Similarly, arguments that mind cannot be reduced to matter were made in the ancient world by many authors, such as Plato, Aristotle, Plotinus, and Augustine.{16} Following the latter, the medievals developed the doctrine of divine illumination, which held that the acquisition of knowledge requires the action of God.{17} In the modern era the irreducibility of mind found expression in the writings of Descartes, Locke, Leibniz, Kant, and others.{18} Lewis’s argument about the correspondence between our minds and the universe also has a long history behind it. Thomas Oden cites Clement of Alexandria, Tertullian, Bonaventure, Aquinas, Peirce, Bergson, and others as defenders of it.{19}

While there is thus a tradition behind Lewis’s argument, there are three particular sources that informed him. The first is one Lewis cites in his autobiography:{20} his friend Owen Barfield. Barfield was a theosophist, and while he failed to convert Lewis that far,{21} he did manage to convince him that there is an inconsistency between accepting that mindless matter is the bedrock of reality, and also “that abstract thought (if obedient to logical rules) gave indisputable truth.” This, however, seemed inconsistent: “If thought were a purely subjective event, these claims for it would have to be abandoned.”{22} Mind, Lewis concluded, must in some sense be independent of the natural world.

A second source of Lewis’s argument is the philosopher and British Prime Minister Arthur James Balfour. In the late 19th and early 20th centuries, Balfour wrote several philosophical tomes defending the idea that “familiar beliefs” -- beliefs about the validity of ethics, aesthetics, and especially reason -- cannot be justified on materialistic terms,{23} receiving criticism from the likes of Bertrand Russell and G.E. Moore.{24} Lewis never cites Balfour in his statements of the argument, but he does refer to Theism and Humanism as “a book too little read,”{25} and lists it as one of ten books that exerted the most influence on his thought.{26} Balfour’s impact on Lewis’s version of the argument has only recently been recognized,{27} but it has been sufficient for Theism and Humanism to be republished with the subtitle The Book that Influenced C.S. Lewis.

A third source is G.K. Chesterton. In Orthodoxy (in a chapter entitled “The Suicide of Thought”), Chesterton argues that “If you are merely a sceptic, you must sooner or later ask yourself the question, ‘Why should anything go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape.’”{28} Similarly, in an essay entitled “The Wind and the Trees,” Chesterton compares the view that the mind is able to move the body, and therefore transcends the body, to the idea that the wind moves the trees. Just as we see the trees move and posit an unseen force moving them (the wind), so we see the body move and posit an unseen force moving it (the mind). This is the “great human dogma.” On the other hand, “The great human heresy is that the trees move the wind.”{29} This is the view that the body moves the mind, and that everything appearing in the mind is actually a product of the body. In this case, we try to explain the unseen in light of the seen rather than vice-versa. This might be reasonable except for the fact that it leads to the very absurdity that the argument from reason postulates: “The man who represents all thought as an accident of environment is simply smashing and discrediting all his own thoughts -- including that one.” All thinking must therefore “treat the human mind as having an ultimate authority,”{30} and this cannot be done if it is “an accident of environment.”

Lewis revered Chesterton as having “more sense than all the other moderns put together,”{31} and seems to obliquely refer to Chesterton’s essay in the same place where he praises Balfour:{32} “If minds are wholly dependent on brains, and brains on biochemistry, and biochemistry (in the long run) on the meaningless flux of the atoms, I cannot understand how the thought of those minds should have any more significance than the sound of the wind in the trees.”{33}

Of course, Lewis was extraordinarily well read, so these three were not the only influences on his development of the argument from reason. When he needed a succinct statement of it, he turned to J.B.S. Haldane: “If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true … and hence I have no reason for supposing my brain to be composed of atoms.”{34} The physicist Arthur Eddington, whom Lewis quotes for different points,{35} also presented a version in his lecture Science and the Unseen World.{36} One wonders whether Lewis had Eddington in mind when he wrote how science had compelled some “modern physicists” to “think about realities [they] can’t touch and see.”{37}

Further influences beyond this, however, are conjectural. Prior to, and concurrent with, Lewis’s original argument (as published in the 1940s), similar arguments were made by H.W.B. Joseph, A.E. Taylor, Wilbur Marshall Urban, and others.{38}

I have temporarily removed the content of three posts because they have some similarities with an article I wrote that is being published in an academic journal. Both the article and the blogpost share the same origin, a paper I wrote in my graduate studies. Even though a blogpost probably doesn't count as having previously published the material, I'm taking them off the blog in order to avoid the appearance of impropriety. I'll put them back online in a year or so.

Quote of the Day

...eternal living is a sense of place, of environment, where God is. In that place, one has no legitimate grounds for worry. Jesus is famous for saying just that. You can abandon yourself to God, who is present. "Let go and let God" is an old and wise saying -- unfortunately more widely said than practiced. Daniel's three friends, facing death in a "fiery furnace," were commanded to bow to the image set up by King Nebuchadnezzar. Their response to the king was that they did not even need to think about it (Dan. 3:16-18). Their God would or would not deliver them, but in either case all was well. They would not bow.

Philosophers in the Chronicle

The Chronicle of Higher Education has an interesting article on William Lane Craig, who remains an incredibly prolific spokesman for evangelical Christianity. He's published over 120 articles in academic journals, mostly of philosophy and theology. Here's his website. On the other hand, there's another article in the Chronicle on Colin McGinn who recently resigned over allegations of sexual harassment. That article, unfortunately, is only available to subscribers. Maverick Philosopher provides some links to McGinn's side of the story.

After Aristotle

I just added After Aristotle to the sidebar, under the "Site Seeing" rubric. It's a blog written by a philosopher, and going over what he's posted so far impressed me mightily. Check it out.

Update: I just added Edward Feser's blog as well, something I should have done a long time ago. Thanks to Pedro Erik in the comments for pointing it out. You might want to check out Feser's summary of his posts on Thomas Nagel's Mind and Cosmos. It's really outstanding.
