What Is Modus Ponens?


Modus ponens is a valid argument form. Because the form is deductive and has two premises and a conclusion, modus pones is an example of a syllogism. (A syllogism is any  deductive argument with two premises and a conclusion.)

The Latin phrase ‘modus ponens‘, translated literally, means ‘mode of affirming’.

Shown schematically, this form of argument looks like this:

Premise 1: If A then B.

Premise 2: A.

Conclusion: Therefore, B.

Arguments of this form are produced by substituting statements in English for A and for B. For example, suppose A = ‘Casey is a dog’ and B = ‘Casey has four legs.’ We can substitute as follows, for a valid argument:

Premise 1: If Casey is a dog, then Casey has four legs.

Premise 2: Casey is a dog.

Conclusion: Therefore, Casey has four legs.

Any argument of this form is valid. But not every argument of this form is sound. For an argument to be sound, it must meet two requirements. First, it must be valid; second, it must have true premises. The above argument about Casey is valid, but it’s not sound. Why? Because the first premise is false. It implies that all dogs have four legs. But this generalization, unfortunately, is not true.

Because modus ponens arguments are always valid, we may extrapolate from this argument form a rule of inference as follows:

“Always infer B from the conjunction of two premises, if one premise is a conditional statement of the form ‘If A, then B,’ and the other premise affirms A.” (The order of the premises doesn’t matter.)

Caveat:

Be careful not to confuse modus ponens with modus tolendo ponens. Modus tolendo ponens is an argument of the following form:

Premise 1: Either A or B.

Premise 2: Not-A.

Therefore, B.

Teaching Logic & Critical Thinking to Your Kids

Cover of Being Logical: A Guide to Good Thinking

It’s pleasing to know that parents are taking a more proactive role in the education of their children, whether or not they are homeschooling. I’ve been asked if I can recommend tools that could be used to teach children the elements of logic and critical thinking.

  1. My first suggestion is that the best way to teach children how to think critically is to be a visible model of critical thinking. Children have a far greater aptitude for critical thinking than adults credit them for. They tend to be good at inferential reasoning. Their powers are limited in part by their limited storehouse of information from which to make inferences.
  2. Modeling excellence in critical thinking presupposes skill in critical thinking. So parents need to be students of logic and critical thinking themselves. Unfortunately, most have not had the opportunity for formal education in these skills. But there are accessible books to consider. I’ll add a list of recommendations at the end of this post.
  3. If your children see you making the attempt to sharpen your skills in reasoning, this will itself be a good example to them. You can tell them what you’re learning.
  4. Learn the names of basic inferential moves (for example modus ponens, modus tollens) and use these labels with your children when they demonstrate their own ability to make such moves. This should reinforce their awareness of the significance of their mental powers, and affirm them in the use of their powers.
  5. Encourage your children to think about the implications of something they have said or heard. You’ll have to be alert to opportunities for this. But once you’ve been at it for awhile, you’ll get into a natural groove. It will eventually become a part of your routine interaction with your kids. How to do this? I’ll save that for another post sometime.
  6. Get your children reading at their grade level (or above!) books that exemplify and encourage critical thinking. Mystery and suspense novels, carefully selected for their sophistication and interest, can be useful. I read the Hardy Boys as a kid. I also liked the stories of the Sugar Creek Gang.
  7. If you’re home schooling (or not), you can include in the curriculum some materials that teach critical thinking. The Fallacy Detective is a good source for this. (See below.)

Recommendations:

So, here are a few of the many resources available. I’m recommending those that provide a good place to start. Each title is linked to its Amazon page.

Books that inspire parents and other educators to teach children these skills:

Books for self-education in logic and critical thinking:

With adequate preparation in the early years, children in junior high and high school may be ready to work through these books themselves. They don’t provide a complete education in logic, but they are satisfactory for pre-college preparation. For more rigorous study in high school, I recommend using one of two textbooks:

Like most textbooks, Copi and Hurley are pricey. So you may want to settle for a second-hand copy. The illustrations and exposition of old editions will be dated, but the logic will be the same! I shop for second-hand books at AbeBooks.com.

For grade school and up:

Fiction classics for youth:

Does “Somewhere in Between” Mean “Ideologically Neutral”?


At Politico.com, Michael Calderon has a piece assessing the significance of the drop in viewership at CNN—“CNN fades in prime-time picture.” The brief article is mostly just straight reporting.

  1. Viewers seem to rely on CNN the most at election time, while turning to other cable networks during the long intervals between elections.
  2. CNN just won a Peabody Award.
  3. Doubts have been raised about whether CNN will be able to compete with MSNBC and FOX.
  4. CNN president Jon Klein says yes and that he can explain evidence to the contrary.
  5. Anderson Cooper is CNN’s most valued trick pony, followed by Campbell Brown (who’s about to return from maternity leave).
  6. Cooper’s ratings have fallen off dramatically in recent months, and it’s expected that this will continue.
  7. CNN staffers and former staffers report that concerns within the ranks are greater than reported by Klein.
  8. The critical demographic is viewers ages 25-54.

These are the “facts”—except for the part about the trick ponies, which I slipped in. And there’s a reason why I use the term “trick pony” to refer to cable TV “news” anchors. To begin, the persona of an anchor is crucial to nabbing and keeping viewers. Everyone acknowledges that. But we should wonder why.

The answer may seem obvious. Take CNN, for example. They claim to be “the most trusted news . . .” Leave aside the question whether the tag captures the truth. Why would they be trusted more than the other networks? Remember, the answer has to have something to do with persona. So why would Anderson Cooper, the leading news anchor for CNN, be, in effect, the most trusted news reporter, period?

The answer we’re supposed to come up with is that CNN is ideologically neutral, and Anderson Cooper is the embodiment of that neutrality. And, we must remember, ideological neutrality is good . . . if it’s news you want.

Calderon begins to reveal this outlook early on, when he contrasts the CNN strategy with the “more opinionated programming” at FOX and MSNBC. Notice that—FOX and MSNBC are “more opinionated” in their programming. Maybe that’s true. But what does it mean, and why believe it?

Well, a network can be more or less opinionated. FOX and MSNBC are “more.” So CNN is “less.” Thus, it follows that CNN may also be airing “opinionated programming,” but just not as much as FOX and MSNBC. But then, what is this more or less of opinionated programming? And are viewers supposed to be able to tell when it’s happening and when it isn’t?

Surely things aren’t that simple.

I think we can agree that Keith Olberman is an opinionated guy, and that he unleashes his opinions pretty regularly on his show at MSNBC. Sean Hannity comes to mind when thinking of FOX. So does Bill O’Reilly, who has created a whole new meaning for the phrase “I’ll let you have the last word.” (If you’re a guest with whom he disagrees, he will, indeed, “let you have it.”)

We agree in thinking that prominent anchors at MSNBC and FOX are “opinionated” because it’s obvious. But here’s the significant point: what’s obvious is what their opinion is. That is, they make it obvious that they are presenting an “opinion” because they tell us when they are giving us their opinion.

Why is this so significant? Because opinions don’t always come flying at us with banners telling us that we’re in the trajectory of an opinion. Often they sneak up on us, clothed with disclaimers that their message is completely “objective.”

Calderon is mistaken in suggesting that CNN is ideologically neutral on the grounds presented by him in his piece. Being neither overtly conservative nor overtly liberal, in the style of FOX and MSNBC, respectively, does not mean that CNN is “in the middle” or “neutral.” It has been convincingly argued that they are not neutral but considerably left of center.

Viewers need skills in detecting the ideological commitments of media outlets, the more so when their commitments are more subtly packaged and publicly advertised as “neutral.”

President Obama’s Argument for Bipartisan Support for the Confirmation of Sonia Sotomayor


A few days ago, President Obama announced his first nominee for Supreme Court Justice. Among the various tools the President has used to get his message out is his website, where a 4-minute video announcement is posted here. I encourage you to view this video. I also encourage you to think carefully about what the President says at each stage in his announcement.

Here’s a specific question to consider:

  • Can you identify President Obama’s argument that Sonia Sotomayor should be a bipartisan slam dunk for confirmation by the Congress?

He makes an argument toward the end of his speech. He doesn’t say, “Let me give you a good argument for this.” But he does make an argument. If we’re paying attention, we’ll recognize the argument. And if we’re critically engaged, we’ll make a sober judgment about the plausibility of his argument.

So the second question I have for you is:

  • Does the President make a good argument that Sonia Sotomayor should be a bipartisan slam dunk for confirmation by the Congress?

These questions are rooted in my goal to encourage greater understanding of media messages—whether from the President, or anyone else.

By greater understanding I mean deeper awareness of what the message is and whether that message is reasonable. The President’s speech, because it is addressed to ordinary citizens and because it can be viewed very conveniently online, presents us with a great opportunity to hone the skills needed to be responsible citizens of a fragile democracy.

William Lane Craig vs. Christopher Hitchens: First Report


Tonight, Biola University hosted a debate between William Lane Craig and Christopher Hitchens on the question “Does God Exist?” The debate was moderated by Hugh Hewitt and seen live by several thousand in attendance at Biola and many more at remote locations in 30 states and several countries.

I’ve just returned home from the event and will record a number of my observations as a first report from the front lines.

  1. This event was no mere spectacle, but a legitimate debate that addressed substantive arguments.
  2. Everybody behaved themselves, including members of the audience.
  3. Bill Craig made two claims in his opening argument: (A) There are no good arguments for atheism, and (B) there are several good arguments for the existence of God (theism). The balance of his opening argument was devoted to four carefully delineated arguments and a fifth thesis about the role of experience in grounding belief in God. This organization of the case for God’s existence has been used by Bill Craig time and again. The first argument is a cosmological argument, based on the origin of the universe. The second was a version of the teleological argument that emphasizes the improbability of the existence of a universe inhabited by human beings, given the evidence of both physics and biology. Third, he argued that the best explanation for the existence of objective moral facts is the existence of God. Fourth, he stated three sets of historical facts that are uniformly accepted by New Testament scholars, which together provide ample evidence that Jesus Christ rose from the dead, implying the occurrence of an important miracle and hence the existence of God. Each argument was constructed as a valid deductive argument, so that rational denial of the conclusion would require a direct challenge to one or more of the premises in each argument. His fifth point was that belief in God can as well be grounded in direct experience of God, though this is not to be confused with an argument for the existence of God. He ended with a challenge to Christopher Hitchens to show how these arguments err, and also argue that God does not exist.
  4. Bill Craig made the interesting point that believers in God should not be so distracted by arguments for the existence of God that they miss the experience of God.
  5. In his opening argument, Christopher Hitchens argued first that Bill Craig is not a consistent evidentialist, and that, to the extent that Craig is an evidentialist, he is, like any evidentialist Christian, a “retrospective evidentialist” who appeals to evidence now that no theist could have centuries ago. Further to this point, Hitchens suggested that contemporary (Christian) theists have, in the face of scientific evidence for evolution, “retreated” from their earlier strategies by claiming that evolution is evidence for theism, or is at least compatible with theism. Next he argued that even if God did exist (by which I think he meant the God mentioned in the conclusion of Craig’s arguments), no reason has been given to believe that this God cares, while there are reasons to think this God is indifferent. (I think, consistent with his practice in his book god Is Not Great, Hitchens would use the word “god” without caps.) His third point was that Craig is obligated to “prove to a certainty” that God exists, while atheists like himself rightly value the role of doubt in the absence of evidence and intellectual humility. This led directly to disclaimers about Craig’s definition of the term “atheism”—Hitchens regards himself as an “a-theist” in the sense that he believes no good reasons exist for believing God exists and so he does not believe that God does exist. Thus, he does not claim to know that God does not exist; therefore, he has no obligation to argue that God does not exist. He concluded with a direct response to the teleological, or fine-tuning argument, for theism. First he said that most physicists acknowledge that “we hardly know what we don’t know” about the origin of the universe and its early history. This looks more like an objection to Craig’s cosmological argument, so Hitchens may have mispoken. He then said there were three “layman’s reasons” for rejecting the fine-tuning argument. I was only able to distinguish two, since they were not enumerated clearly. First, he asked whether prior to the beginning of the universe there was pre-existing matter, as a step toward the question, “Who designed the Designer?” Second, he asked whether theists have considered the “nothingness that is coming,” his point being that the universe will eventually fade into oblivion and that therefore the so-called “Designer” seems to have designed poorly.
  6. The two opening speeches differed dramatically. Bill Craig laid out a case in straightforward manner, with numbered premises and his conclusion. (A complete outline of his cumulative case was included on one sheet of the program that was printed for the occasion.) Christopher Hitchens adopted more of a narrative style that was more loosely argued and less linear in its progression. Both were articulate and engaging.
  7. In the rebuttal, cross-examination, and response portions of the debate that followed, Bill Craig pressed Christopher Hitchens on his conception of atheism, his reasons for being an atheist, and his responses to the arguments presented in Craig’s opening speech. In this respect, Craig was in greater control of themes in the debate. This was helped immensely by the clear progression, crisp identification, and repetition of his original arguments. Hitchens resisted Craig’s efforts to extract a more precise definition of Hitchens’s atheism than his simple denial that there is adequate evidence for theism. Hitchens claimed that if you believe the universe is designed, then you also have to believe the designer is short on the excellence attributed by theists to God. There is a tension between there being a god who is completely indifferent to human suffering, or a god who provides a bizarre remedy in the form of having “someone tortured to death during the Bronze Age” and Roman rule, a god who demands conformity to his requirements in order to be saved from damnation, and, in any case, who leaves countless individuals without opportunity to hear about and accept this remedy.
  8. The most noteworthy difference between these debaters consists in this: preparation. One may agree or disagree with Bill Craig’s claims, but there can be no question that he was thoroughly prepared for every aspect of the debate and never faltered in his response to objections by Hitchens. Christopher Hitchens, on the other hand, dropped several of Craig’s opening arguments, and seriously misunderstood or distorted the moral argument, the argument from the resurrection of Jesus, and Craig’s appeal to experience. I think Craig was most successful in demonstrating the error in Hitchens’s discombobulated rendition of Craig’s moral argument. Whether the audience followed the competing interpretations of N. T. Wright’s historical argument concerning the probability of the resurrection is another matter. But I can vouch for Craig’s construal of Wright’s argument, and, for that matter, for Hitchens’s confusion on the point. As for the appeal to experience of God (and the witness of the Holy Spirit), I might have put the point differently than Craig did and treat it as a kind of evidence that serves the subject of the experience without the need for argument. But Bill Craig and I may have a different view of the epistemology of such experience.
  9. Christopher Hitchens made a couple of odd points in his rebuttal, as if to answer arguments or objections that Bill Craig had not given. For example, he asserted that he believes in free will, and went on about it as if Craig had pressed him directly on this point. This was a strategic mistake, if only because it wasted valuable time that should have been devoted to what was already on the table. Worse, Craig could have challenged Hitchens’s claim to believe in free will, given his naturalism. I gather that Hitchens sensed this, saw its relevance to the question of moral conduct, and attempted to pre-empt Craig on the point. But Hitchens’s complete failure to understand the moral argument presented by Craig landed him in enough serious trouble as it was. Hitchens also digressed about the embarrassing canonization of Mother Theresa by the Roman Catholic Church. I suppose he couldn’t resist, since he had written a whole book on the subject. (See this link for the crass title of that book.)
  10. The only thing that surprised me about Bill Craig’s strategy in the debate was his determination to get Hitchens to specify more precisely his self-identification as an atheist. Much of Craig’s cross-examination time was taken up with this question. That is due in part to Hitchens’s bobbing and weaving on the point. I understand Craig’s rationale for tasking Hitchens with clarification of his position. I’ve encountered the same maneuver in my debates with Michael Shermer and Greg Cavin, for example. As I see it, regardless of the standards of formal debate, both parties to a debate of such existential significance should be clear about their own positions and be prepared to present good reasons for them. (While this is a burden of proof issue, the term “burden of proof” never came up, if I remember correctly.) Christopher Hitchens has a worldview. It is thoroughly naturalistic and scientistic, and indeed materialistic. It hardly matters what he means by “atheism” in application to himself, since this is clearly his positive stance. And he made no attempt to argue that his worldview is true. Bill Craig is right about this.
  11. Christopher Hitchens’s attempt to distinguish between the hubris of the argumentative theist (my term) and the intellectual humility of his kind of atheist was totally unconvincing. Hitchens’s tone in the debate, consistent with his hallmark practice, belied his disclaimers about claims to knowledge. Once, in his closing argument, Bill Craig drew attention to this point, and did so dramatically but graciously. He pointed out that Hitchens made his own truth claims on behalf of atheism, that he did so without supporting argument, and that “you’ve got to come to a debate prepared with arguments.” While Hitchens did make arguments, they were largely unfocused, sometimes disconnected, and often irrelevant.
  12. The second half of cross-examination must have been interesting to the predominantly evangelical audience. Christopher Hitchens asked Bill Craig directly whether he believes that there are devils, that Jesus was born of a virgin, that some nonChristian religions are false, and that some Christian denominations entertain false beliefs. Craig answered each, respectively: yes, yes, yes, and yes. But he added (a) that the existence or non-existence of demons has no bearing on his argument from the resurrection for theism, (b) that while he did not think the virgin birth could be proved, whether it happened is also irrelevant to his case for theism, (c) that Islam is among the false religions, and (d) that while there are differences among Christian brethren (Craig is not a Calvinist but more of a Wesleyan, for example), their differences are on less substantive points. While Craig may not have expected this line of questioning, he answered well. It was a sign of Hitchens’s lack of preparation, I believe, that his cross-examination of Craig was unproductive. (One further indication of this is that Craig’s answers were never brought up for special criticism.)
  13. The main development of the cross-examination period is that Hitchens allowed that morality could be “purely evolutionary and functional.” Given his comments on morality throughout the evening, I don’t see how they could be anything else than that on his view. Thus, he is, Craig would argue, caught in a contradiction if he also claims that morality is objective in the sense Craig defined. And Hitchens had made such a claim. Note: Hitchens could hardly have denied this and remained consistent with his condemnation of religion in his book.
  14. Speaking of Hitchens’s condemnation of religion, I think he found the balance that was needed if he was to remain faithful to the spirit and tone of his book without completely alienating his audience. His diatribes in god Is Not Great are mean and visceral in the extreme. During tonight’s debate, he was more cautious in his declamations. He did say “I’ll be damned” if I don’t say what I really think of religion and Christianity. But this was mild in comparison with what Hitchen is capable of. The problem is—and he knew this—his off-the-cuff remarks were not germane to the debate. Someone reading his book for the first time after seeing this debate may be surprised by the venom they find, but they probably will not be shocked. I say this because I do think it was a delicate balancing act for him to be more measured while still acting in character.
  15. Christopher Hitchens attempted to drag Old Testament accounts of “genocide” and other divine sanctions of dubious moral character into the debate. This was predictable. Bill Craig rightly noted that these complaints concern the inerrancy and inspiration of Scripture, and are not salient to his case for theism. Some in the audience may have wondered how Craig could avoid these issues and also invoke the New Testament in describing the grandeur of God’s plan of salvation. As it happens, Hitchens didn’t raise the point. But it also happens that there is no inconsistency in Craig’s view of the bearing of Scripture on aspects of the debate.
  16. Another comparison of interest to me has to do with the existential appeal of their respective points of view. Bill Craig seemed actually to be enjoying the dialogue (as one of my daughters noted). Certainly he was unapologetic about his Christian faith. He spoke convincingly of the transformation of his life after believing in Christ. And he explained the basis Christians have for hope in this life and the next. He even urged Christopher Hitchens to become a Christian, since Hitchens wants to say that there are objective moral values but can’t account for them in his worldview. Craig said this without seeming the least bit supercilious. I thought Craig struck an excellent balance in describing the future hope of Christians and its bearing on the endurance of suffering now, and a Christian activism on behalf of those who are oppressed or even deprived of life. For his part, Hitchens explained that he finds meaning in life by seeking liberty for himself and for others, and that, since so much violence against humanity is done in the name of religion, he is constrained to combat religion publicly.
  17. I’ve already mentioned how Christopher Hitchens responded to Bill Craig’s moral argument for theism. It struck me that this argument was the most widely discussed of them all. The irony is that for all that he had to say in response, Hitchens actually “dropped” the argument. (To say that he “dropped” the argument is to say, in debate-speak, that he didn’t actually address the argument.) In his response to Craig’s argument, Hitchens recast the argument as an argument that atheists can neither know what is morally right nor do the morally right thing unless they believe in God. That is not the argument at all. It baffles me that so many atheist, agnostic, and skeptical debaters distort this argument so consistently. The question is how to ground the objectivity of moral truths without reference to God, not whether moral truths can be known without believing in God or whether it’s possible to behave morally without believing in God. The point is neither epistemic nor behavioral, but ontological. My preferred formulation of the moral argument is a little different than Craig’s, but my experience has been the same as his. Debate opponents miss the point.
  18. Returning, finally, to something I mentioned previously, this debate exposed a difference in preparation on the part of these two debaters. This is far more significant than it might seem at first. William Lane Craig has debated this topic dozens of times, without wavering from the same basic pattern of argument. He presents the same arguments in the same form, and presses his opponents in the same way for arguments in defense of their own worldviews. He’s consistent. He’s predictable. One might think that this is a liability, that it’s too risky to face a new opponent who has so much opportunity to review Craig’s specific strategy. But tonight’s debate proves otherwise. Hitchens can have no excuse for dropping arguments when he knows—or should know—exactly what to expect. Suppose one replies that William Craig is a more experienced debater and a trained philosopher, while Christopher Hitchens is a journalist working outside the Academy. That simply won’t do as a defense of Hitchens. First, Hitchens is no stranger to debate. Second, he is clearly a skillful polemicist. Third—and most important—Hitchens published a book, god Is Not Great, in which he makes bold claims against religion in general and Christianity in particular. With his book, he threw down the challenge. To his credit, he rose to meet a skillful challenger. But did he rise to the occasion? Did he acquit himself well? At one point he acknowledged that some of his objections to the designer argument were “layman’s” objections. His book, I believe, is also the work of a layman. It appears to have been written for popular consumption and without concern for accountability to Christians whose lives are dedicated to the defense of the Gospel.

Much more can be said about the debate. I’m confident that it will elicit much discussion worldwide. Viewers and listeners will draw their own conclusions. But after tonight, there is reason to think—as Bill Craig suggested—that we may soon witness a great renaissance of Christianity.

Michael Dirda on “The Knowledge Most Worth Having”


My education in the value of the personal essay probably began in a time and space I don’t recall. But I was compelled to appreciate this specialized form of literature most memorably during my reading of Philip Lopate’s collection The Art of the Personal Essay. The enthusiasm inspired by his anthology resulted in a welcome appetite for more of the same. Lopate’s genius for selecting the best of the breed was proven by the difficulty I experienced during my search for collections of comparable value. The annual publication of books in The Best American Essays series, edited by Robert Atwan, sometimes approximates the Lopate standard. And there are other worthy collections. Thankfully, my quest for the best has put me in touch with individual authors, contemporary essayists of the first rank, whose writing is consistently creative, wise, and ennobling.

My favorite contemporary essayists include Michael Dirda, Joseph Epstein, John Updike, and many others. This post loiters in one section of one essay from Michael dirdabook-by-bookDirda’s book Book by Book: Notes on Reading and Life. The essay is titled “The Pleasures of Learning,” and the section I’ve isolated for consideration here is called “The Knowledge Most Worth Having.” This section consists of seven sentences, followed by a list of sixteen items, and a concluding sentence that reads:

Know these well, and nearly all of world literature will be an open book to you.

Clearly, Dirda’s reference to “the knowledge most worth having” is circumscribed by a specific purpose. He doesn’t mean to catalog all that it is most important to know. More precisely, he asks, “What should a person know of the world’s literature?” This question presupposes that some works are more worthy of our time and meditation than others, and that if we are to have a “structured reading program” we must have a criterion for determining which works are most deserving. Dirda gives us a criterion and then “a roughly chronological short  list of those that the diligent might read in a year or two.” Both the criterion and the list are interesting.

Dirda’s criterion—the test he uses in deciding which authors and which works are most rewarding for the reader who would attain a knowledge of the world’s literature—is simple. Devote yourself to those works “that later authors regularly build on, allude to, work against.”  Dirda does not elaborate on the principle, except to bestow a name on works that meet this condition; they are “the great patterning works.”

For further insight into the principle, we might consider Dirda’s list. He does not claim that it’s exhaustive. Actually, he implies that it is not. It’s a place to begin. Still, it’s a comfort to hear that “there aren’t many of these key books,” and it’s enticing to be told that “they aren’t all obvious classics.” One might spend a year or two in the company of these books, and then move on to others.

Before I reveal the list, I want to ask, again, what is the point of the list? It is to commend works with the potential to crack open the world of great literature. These works have this power because other authors have built on them, alluded to them, and worked against them. They are, in other words, touchstones for so much great literature that our capacity to appreciate and know the greatness of other works is unlocked by our acquaintance with these.

Now to the list. It is no surprise that it begins with

  • The Bible (Old and New Testaments)

Dirda recommends the Authorized, or King James, Version because it’s “the one that has most influenced the diction and imagery of English prose.” As a kid, I attended a Baptist Sunday School that used the King James Bible in Bible lessons, Scripture memory, and “sword drills.” (Incidentally, I never heard anyone seriously proffer a defense of the KJV on the grounds that “if it was good enough for Saint Paul, it’s good enough for me.” My Sunday school teachers were far more sophisticated than that.) In the third grade, taught by my mother, we children were awarded Bibles of our own—the King James Version, of course. Shortly after that, the production of new English translations began in earnest, and today the original KJV of 1611 is little known, even by those who know the Bible. I’m a proponent of the multiple versions doctrine, that individual versions or translations have their distinctive virtues, and that more than one should be consulted in the serious study of the Bible. But Dirda is hardly alone in proclaiming the incomparable linguistic beauty and legendary influence of the KJV, and I do not disagree. (For those interested in the translation debate, I recommend D. A. Carson’s book The King James Version Debate: A Plea for Realism.)

Next on the list:

The items listed by Dirda are not annotated. He doesn’t say why an entry meets the criterion he’s adopted. But some source containing the ancient myths of Greek, Roman, and Norse provenance is a no-brainer, and Bulfinch’s is the industry standard. Oddly, my copy of the generally reliable Benét’s Reader’s Encyclopedia (mine is the 3rd edition) has no entry for this classic collection. But then, neither does my handy paperback copy of The Reader’s Companion to World Literature. No matter. The important thing is that allusions to mythologies abound in acknowledged “great literature.” The reason for this is worthy of contemplation, but beyond the scope of this post.

Fine. If ancient mythologies must be known on the grounds that they are sources for innumerable allusions, then Homer’s influence is no less significant. The Ionian poet as a man is a mystery. Even his actual existence is doubted. The story of the composition, preservation, and function of “Homer” among the ancient Greeks is interesting in its own right, and is told with clarity uncompromised by brevity in . . . Benét’s.

We begin to suspect that the influence of the ancients runs deep in our literature. Plutarch, who lived in the first century of the Common Era, is best known as a biographer. It’s an irony of history and of literature that little is known about Plutarch himself—no biographer for the biographer. Shakespeare made use of Plutarch in two of his great plays. (Plutarch was, by the way, a master of the personal essay, and his compendium, the Moralia, has survived to please readers to this day.)

So far, Dirda’s choices are obvious. Of course Dante. But why the Inferno and not the whole the the Divine Comedy? Dirda doesn’t declare. So let’s speculate. The Inferno is the first part of the Divine Comedy. So maybe you read the first part and can’t put it down. Or you do put it down, but you’ve had enough Dante for the purposes envisioned by Dirda. Imaginative writing about hell does make for scintillating writing. For some, heaven is boring in comparison, and a proffered reason for indifference about the soul’s destiny. Strange logic.

Next in line:

I confess that I was initially surprised by this entry from the early Middle Ages. But I shouldn’t have been. This is our source for Ali Baba, Aladdin and his Magic Lamp, Sinbad the Sailor, and the phrase “Open Sesame” (which appeals to our get-rich-quick aspirations). The story of Sultan Shahriar and his clever wife Shaharazad is endlessly intriguing. But a guide to The Arabian Nights would be useful, if only because of its length.

The Middle Ages brings to mind the next fairly obvious choice:

  • Thomas Malory, Le Morte D’Arthur (tales of King Arthur and his knights)

Seeing the Monty Python movie is no substitute for reading the book. Take my word for it. But it does give a sense of the book that is somewhat surprising. (Take that with a grain of salt.) The written tales were probably composed in prison by a chap who commended the ideals  of chivalry and was notorious for violating those same ideals. Alfred, Lord Tennyson, was very much taken with these tales, and transcribed them into epic poetry in his Idylls of the King. Here is a clear case where one legendary author, the Victorian poet Tennyson, is understood better against background knowledge of a 15th century author of legend.

You knew he had to show up on the list eventually, and if you’ve been following the chronology, you may have suspected his appearance at any moment—William Shakespeare.

Some of these have been quite respectably adapted for film. Hamlet, starring Mel Gibson (1990) finally made sense of “words, words, words” to me. The Orson Welles film Chimes at Midnight (1965), featuring Welles as Falstaff and John Gielgud as Henry IV, was a favorite of Welles and is generally thought to be one of his greatest movies.

There have been a dozen or more adaptations of King Lear. Most celebrated is the 1983 version starring Laurence Olivier and Dianna Rigg. Another cinematic reprise is planned. How would you like to see Naomi Watts, Keira Knightley, and Gwyneth Paltrow as the three daughters of King Lear, played by Anthony Hopkins? It’s in the works. So now is an especially auspicious time to have a read of the original King Lear.

Film or television adaptations of A Midsummer Night’s Dream were released in 1935, 1968, 1996, 1999, 2002, and 2005. Enough said.

An adaptation of The Tempest is said to be in production. It won’t be the first. The Tempest was first “screened” in 1905, in a two-and-a-half minute production. The play enjoyed a science fiction adaptation in 1956 in the film The Forbidden Planet. Other adaptations were screened in 1982, 1991, 1992 (in animation that is faithful to Shakespeare).

These works by Shakespeare are immortal. The enjoyment of a worthy film adaptation is enriched by a reading of Shakepeare himself.

Michael Dirda’s list continues. But here the entries shade into the controversial.

Miguel de Cervantes Saavedra introduced his dubious but endearing hero, the Man of La Mancha, in two volumes (1605 and 1616). Cervantes is credited by many as the first modern novelist. Since he died in 1616, that’s quite a distinction. The only thing controversial about including Don Quixote on Dirda’s short list is that the list is so short. Some would argue that the inclusion of Don Quixote obliges the inclusion of some other great work not on the list. But the fact is, this grand novel supremely fits Dirda’s criterion. If you disagree, you’re tilting at windmills.

A shade more controversial are

and

Defoe wrote something like 250 works. They call that prolific. Businessman, journalist, government representative, spy, possibly even double agent, but best known for his novel Robinson Crusoe, or The Life and Strange Surprising Adventures of Robinson Crusoe, of York, Mariner. Through this depiction of a solitary figure stranded on an island, we learn how noble men might conduct themselves under such conditions. Crusoe is an admirable figure, with lessons to teach us all. Who hasn’t imagined what it would be like, what we would do, what we would become, if we were to live in such forced seclusion?

Swift was a genius. As evidence for this, I take the liberty of quoting:

Gulliver’s Travels is perhaps the sole major work in all English literature that has continuously led a double life: it has been at once one of the most glamorous of children’s adventure stories and one of the most pungent critiques of humanity addressed to the mature imagination. This almost incredible marriage of opposites is possible because in the main the disturbing satire for adults lurks inconspicuously behind the pleasantly exciting façade of the explorer’s tale; the child can rarely see behind the façade, and the adult can never cease seeing behind it or trying to pierce through it. Further, there are times when Swift is entirely concerned with the façade—of the elaboration of the details of the story for its own sake . . . and the presence of such passages assists the young reader—or the unperceptive reader generally—to take the whole story at the simplest level of meaning. . . . Swift’s obvious enjoyment of playing the game—of unusual sizes, mysterious phenomena, and strangely shaped creatures—gives zest to his narrative without in any way impeding him when he chooses to make the game philosophical. (The Reader’s Companion to World Literature, 226)

Dirda’s inclusion of Gulliver’s Travels is vindicted by the suggestion that this satire “draws upon at least five traditions of world literature,” and the claim that “the use of fantasy for serious statement, virtually eliminated by two centuries of emphasis upon realism, is reappearing in our own day” (The Reader’s Companion to World Literature, 229).

Dirda goes on to add items undeniably suited to his premise. But these, I confess, lie at the periphery of my own reading interests:

and

Fairy tales and folk tales. Their influence has been great. My interest is negligible. For the record, the noted study of folklore and human society is James Frazer’s The Golden Bough.

The final three works are perhaps the most controversial choices. Again, one could argue that some other work is more worthy of inclusion on such a list.

I believe a rationale may be built for each of these entries. Notice, Jane Austin is the only woman to be valorized on the basis of Dirda’s criterion. Some readers might object to this. I know some writers would have filled in with other great female authors just to avoid the appearance of impropriety and escape censure by enforcers of political correctness. But this is Dirda’s list.

There should be considerable pride in and no prejudice against the admission of Jane Austin to the august company of writers of seminal importance. (I hope that doesn’t sound like a bad pun or a contradiction in terms.) In 2003, the BBC sponsored a program called The Big Read, in quest of “the nation’s best-loved novel.” Pride and Prejudice was voted #2, after Tolkien’s Lord of the Rings. I suspect many titles voted onto the Top 100 list for The Big Read found their way there with the help of recent cinematic adaptations. But Dirda’s basis for including Jane Austin’s novel isn’t current popularity but lasting influence in the field of literature.

Lewis Carroll has to be acknowledged, even by someone without predilections for his plotting and style. Alice in Wonderland falls into that class of fairy tales and folklore that have little appeal for me.

As for The Adventures of Sherlock Holmes, I’m completely sympathetic with ranking it high on a list of entertaining and well-crafted fiction. I would even consider bringing Holmes along for my island exile. I’m less sure of the application of Michael Dirda’s criterion for educating ourselves in preparation for mastery of the world’s great literature. Doyle’s imagination, plotting, and writing style are both creditable and inimitable. But there are others. Agatha Christie has sold better—much better, in fact. Edgar Allen Poe is the acknowledged inventor of the mystery story, and is the namesake for the Edgar Award in mystery fiction. I suppose that Doyle gets the nod because Sherlock Holmes is the paradigmatic sleuth, the one who comes to mind first when that special expertise is needed. Fair enough.

So there you have it. A criterion and a list. I’ve tried to make sense of Dirda’s choices. Using his criterion, and limited to sixteen items, I think he succeeds.

BlogLogic—Rumors of Sarah Palin’s Affiliation with the Alaska Independence Party


It’s been interesting to see how things have unfolded on the Mudflats blog, which purports to be “tiptoeing through the muck of Alaskan politics.”

The host goes by the handle “AKMuckraker.” Today she published a post titled “Palin – Republican Party Infiltrator? Damning Video.” With a title like that, you hardly need to read further to know what’s up:

There’s a video that incriminates Sarah Palin by showing her past ties to the Alaska Independence Party (AIP) and her secret plan to advance that party’s aims by infiltrating the Republican party.

That’s the muckraker’s thesis.

If you want to know what’s so damning about the video, or whether it’s damning at all, then you might want to read the post. The muckraker connects the dots that lead to her conclusion. And she’s remarkably confident of her conclusion.

The only problem is, her evidence doesn’t support her conclusion. Her argument is fallacious. If it’s not a specimen of conscious bias against Palin, it’s at least a case of wishful thinking gone awry.

The video features a small gathering of crazies scheming about how best to achieve the secessionist goals of the Alaska Independence Party. So we’re told. We have to take the muckraker’s word for it that this video is not a setup. We’ll give her the benefit of the doubt here. We’re also told that a key participant seen and heard on the video is Dexter Clark, vice chairman of the Independence party. Fine. We’ll go with that.

The muckraker then provides transcripts of bits of the video. Since these are the portions she uses to make her argument, let’s assume that they are the most damning evidence in support of the muckraker’s conclusion.

The first excerpt shows Dexter Clark estimating the number of American soldiers and dependents who “could be eligible to vote” for Alaska “Statehood.” Of course, Alaska has been a state since 1959. Ah, but it isn’t yet a “State,” as in “independent nation state.” The excerpt doesn’t disambiguate for us, but I take it that Clark is referring to the independent-nation-state kind of state, and he’s calculating the number of votes his party might be able to count on in a referendum on Statehood.

OK?

Well, maybe not. The ensuing paragraph, where the muckraker explains things for us, leaves us in greater suspense. How is “Statehood” really being used here? It isn’t easy to tell.

It might not matter. The basic idea seems to be that the Independence party was shafted by a rigged vote about Alaska Statehood, and the desired result of the AIP went down in smoke.

We come, then, to the next excert, what the muckraker calls “the good part.” Here Clark lauds the election of Sarah Palin to become Alaska’s governor, even though she did so as a Republican. Clark explains why this is good news for his Independence party. Palin had once been a member of the party. The only reason she switched parties and became a Republican was to “get along and go along” (Clark’s words).

At this point, vagueness corrupts the argument. What does Clark mean by “get along and go along”? Presumably, he’s suggesting that at the time of Sarah Palin’s move to the Republican party, she was still an Independence party member at heart and that her new role as a town mayor might work out better if she had the appearance of being a Republican. She couldn’t have been much of a Republican, suggests Dexter Clark, since she discovered that “she all kinds of problems with their ethics.” This is clearly the message that muckraker gleans from Clark’s musings.

The joy in seeing Sarah Palin become governor of Alaska is rooted in Dexter Clark’s perception that Palin remains sympathetic with the AIP cause. And this is based on two things, Palin’s prior membership in the AIP, and Clark’s perception that Palin isn’t a sincere Republican. Clark’s perception that Palin isn’t a sincere Republican is itself based, in part, on Palin’s past association with the AIP. Clark’s perception of Palin’s continued affinities for the AIP is reinforced by his perception of a clash between Sarah Palin and the Republican party over the ethics of the party.

The net effect is supposed to be that Alaskans now have an AIP governor, disguised as a Republican, who can be counted on to reintroduce the issue of Statehood and perhaps facilitate the achievement of the AIP’s primary objective. What makes the whole thing really rich is that, because governor Palin is such a popular figure in her state, many Alaskans would probably vote with the AIP and everything turn out hunky-dory for the AIP.

So strategists in the AIP propose to infiltrate the two mainstream parties, get these pseudo-members elected to municipal and state offices, and watch them use their positions—synchronizing their efforts, of course—to bring about independence for Alaska.

This seems to be the basic trajectory of Clark’s reasoning process.

And the muckraker is floored by this. The video excerpts are so unbelievably damning that the muckraker thinks her readers might want to sit down before they are presented with the evidence she presents.

What’s truly unbelievable is that the muckraker finds the argument so compelling. Indeed, to sort it out you might need to sit down for a spell.

Here’s the argument:

  1. Dexter Clark is the vice chairman of the Alaska Independence Party (AIP). [Fact]
  2. If Dexter Clark is the vice chairman of the AIP, then his proposed strategy for achieving independence has been adopted by the AIP and its members. [Assumption]
  3. Dexter Clark’s strategy for achieving independence has been adopted by the AIP and its members. [MP, 1 and 2]
  4. Dexter Clark’s strategy for achieving independence is for members of the AIP to switch to one of the two main parties, get elected to government positions, and use their new authority to sponsor independence for Alaska.
  5. Members of the AIP agree to switch to one of the two main parties, get elected to government positions, and use their new authority to sponsor independence for Alaska. [Conjunction of 3 and 4]
  6. No member of the AIP ever leaves the AIP except in pursuit of Dexter Clark’s strategy for achieving independence. [Assumption]
  7. If a person who was once a member of the AIP and is now officially a member of the Republican party, then that person has left the AIP and inflitrated the GOP in order to advocate for independence. [Direct implication of 6]
  8. Sarah Palin was once a member of the AIP and is now officially a member of the Republican party. [Assumption or fact, as the case may be; that depends on the truth value of the first conjunct; we can safely believe that the second conjunct is true]
  9. Sarah Palin has left the AIP and inflitrated the GOP in order to advocate for independence. [MP, 7 and 8]
  10. If Sarah Palin has infiltrated the GOP in order to advocate for independence, then Sarah Palin is not a genuine Republican. [Direct implication of 7]
  11. Sarah Palin is not a genuine Republican. [MA, 9 and 10]
  12. If Sarah Palin is not a genuine Republican, then Sarah Palin is unfit to become Vice President of the United State. [Assumption]
  13. Sarah Palin is unfit to become Vice President of the United States. [MP, 11 and 12]
  14. If Sarah Palin is unfit to become Vice President of the United States, then we should not vote for John McCain in this year’s presidential election. [Assumption]
  15. We should not vote for John McCain in this year’s presidential election. [MP, 13 and 14]

Statements 10-15 do not appear in the muckraker’s post. They are gleaned from the tone and content of this and other posts at her blog, and my suspicion that she does not want John McCain to be the next President of the United States. In any case, we can dispense with them here.

The above argument can be simplified by extracting three of the numbered statements, 7-9. The resulting argument is as follows:

  1. If a person was once a member of the AIP and is now officially a member of the Republican party, then that person has left the AIP and inflitrated the GOP in order to advocate for the independence of Alaska. [Assumption]
  2. Sarah Palin was once a member of the AIP and is now officially a member of the Republican party. [Assumption or fact, as the case may be; that depends on the truth value of the first conjunct; we can safely believe that the second conjunct is true]
  3. Sarah Palin has left the AIP and inflitrated the GOP in order to advocate for the independence of Alaska. [MP, 1 and 2]

Notice three things about statement number 1.

First, it is an assumption that is never actually stated in the argument.

Second, it is crucial to the argument, since the muckraker never so much as hints that Sarah Palin was in the room when the video was shot, or even that Sarah Palin has unequivocally embraced Dexter Clark’s strategy for achieving Alaska’s independence.

Third, it isn’t true.

How’s that for a specimen of BlogLogic?

* * *

Why have I written this post?

One should not infer from what I’ve said here that I support the McCain/Palin ticket. That would require another instance of specious reasoning.

I have two reasons for writing this post.

First, Sarah Palin should be defended against arguments that violate the principles of sound reasoning. So should any other candidate. But Palin has been the target of incessant, vicious attack with arguments constructed on manufactured evidence. This seems to be the current number one priority of the muckraker. (Again, that’s what muckrakers do.)

Second, I can at least hope that exposing the barrenness of a BlogArgument—or Blogument, if you will—is a contribution to the common good, as a call to sound reasoning in the public square.
