False Dilemma and C.S. Lewis


(click image to go to original comic location)

Most people are familiar with the false dichotomy (or false dilemma) - the fallacy of presenting two possibilities and claiming they are exhaustive when they are not. The first panel of the comic above provides an example.

The last panel in the comic demonstrates a false trichotomy - the presentation of three possibilities as if they form an exhaustive list ("What about the Flying Spaghetti Monster?").

Although this fallacy should be easy to spot and recognize, I am amazed at how many Christian websites still use a text-book example of a false tri/dichotomy used in Mere Christianity by C.S. Lewis (an explicit example can be found here and here, though I have also seen sites that don't credit - let alone quote - Lewis, though they use his "argument"). Here it is, from Mere Christianity:
A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic - on the level with a man who says he is a poached egg - or he would be the devil of hell. You must take your choice. Either this was, and is, the Son of God, or else a madman or something worse. You can shut Him up for a fool or you can fall at His feet and call Him Lord and God.
This leaves out obvious possibilities. One that immediately springs to mind is that we don't accurately know the sayings of Jesus, so it is completely conceivable that Jesus was a great moral teacher and was misquoted on a few things. Perhaps Jesus was just mistaken - you don't have to be a liar or a lunatic to be mistaken - even about your own identity (especially when you have a group of dedicated followers). A case can be made that Jesus never existed, giving us yet another possibility.

As an aside, let's for a second accept the false trichotomy that Jesus was either a liar, lunatic, or a god. To me, the first two options are still far superior explanations. The fact that Lewis thought the latter was the best, and put this forward as his only argument in Mere Christianity of Jesus' divinity, really shows the depth of his bias. It's regrettable that so many Christian sites use this argument as if it holds any merit - no non-believer would be the least bit swayed by it.

Introductory Philosophy - A Student's Perspective

Anyone who knows me knows I love philosophy. I am currently getting a minor in philosophy along with my bachelor's degree, and plan on continuing my education with a graduate degree in philosophy. The following is my take on how introductory philosophy courses should be taught. Of course, I have absolutely no expertise in either education or philosophy, but this is my opinion as a student (I do have some expertise in being a student, at least!).

There is a stigma about philosophy - people often say it is boring or pointless or bullshit. I find this very odd. Most of the very same people have strong philosophical positions and will use philosophical argumentation to defend those positions (a friend I had who called philosophy bullshit but would use the argument from design to defend his belief in god comes to mind). There are very few people who don't find philosophical discussions of some kind at least a bit interesting. So why is there this stigma?

As a student, I've taken a number of philosophy courses. There is a definite trend in the way any introductory course to a subject in philosophy is taught. They are almost always taught historically. Knowing some history of philosophy is great, and I am not trying to say it isn't of any use. However, historical philosophy isn't the way to hook people new to the subject!

Much of what Socrates said is only really historically important - his theory of forms is sort of interesting, but pretty much any modern reader being introduced to philosophy would just scoff at it. Before we had developed scientific methods and a rich scientific understanding of the universe, much of philosophy was arm-chair philosophy. Philosophers would make grand claims about the way the world was from their proverbial arm-chairs without having these claims substantiated with a rich understanding of the world. This was fine for those times - they were doing the best they could for their time. But taken as a hypothesis nowadays, many philosophical theories that were put forth at some time seem naive and rest on strange assumptions about the way the world works. When put into context with all the scientific knowledge we now have, they just don't seem to cohere well with what we know now. It's hard to describe exactly why the ideas seem stupid because much of the time there isn't anything that directly contradicts them, it's just that much of our understanding makes the theory unlikely and it is hard to articulate (especially for someone new to philosophy) exactly why a theory seems ridiculous.

This makes philosophy seem pointless - all these philosophers just seem to be sitting around making stupid claims! It gives the impression that this is what philosophy is about. The frustrating claims made suck the fun out of philosophical argumentation. To top things off, all the theories seem to be bullshit.

Talking about old philosophical theories isn't always bad, though. Much ancient philosophy is quite good and can still be enlightening now - to take one example out of many, the problem of evil which was first articulated by Epicurus over two thousand years ago (I don't know if he was the first to put forward this argument, but if not that just further shows that really really old philosophy can be good). This argument is still essential in any philosophical discussion of gods. However, another problem in many introductory philosophy courses is to force students to read a translation of the original author. Even the best of translations are often hard to understand, vague to the point that the professor doesn't know exactly what the author is saying, and use strange analogies and examples that make little sense to the modern reader.

This just compounds the frustration. It's one thing to teach frustrating theories, but to make students read hard-to-understand writings just makes it annoying and boring to study philosophy.

When I first got into philosophy, the book I read was The Philosophy Gym by Stephen Law. This book, I think, takes the perfect approach to teaching philosophy. It starts out with the sort of question that would intrigue anyone - the sort of question you and your buddies might argue about sometime (like "Is time travel possible?" "Does god exist?" "Is homosexuality wrong?" "Can robots feel?" etc). It then goes on in a playful dialogue-style, with 2 people each taking side in the issue. It goes through different arguments in an easy to read way, sometimes using historical arguments, sometimes using modern arguments. This makes it very engaging and thought-stimulating.

The interest in philosophy is in every student. Teachers and professors need to take advantage of this, engage the students in a way that will interest them. Concise, engaging readings will encourage students far more than boring historical ones. Topics should be chosen that would actually be interesting for students to discuss. I think this can all be done in an engaging way while still teaching students critical thinking and good argumentation.

So maybe I am just naive about the process of educating students, but this is my opinion as a student. I'm sure things are much more complicated than I make them out to be (it must be hard to make structured lectures with a lot of student participation, and even harder to decide how to mark students if the lectures lacked many facts), but ideally, I think this is how an introductory philosophy course should be taught.

Religulous - A review of a review, and a review

Bill Maher's new documentary on religion, Religulous, is out. I went to see it on Friday, and I found it hilarious. Maher goes around asking religious folks questions. Now, if you're going to see it for a serious criticism of religion, you're going to the wrong place. Maher is a comedian, and this movie shows that. It's funny and engaging, but much less than philosophical. I recommend it to anyone who likes to have a good laugh at the expense of fundamentalist religious belief. If you want to see a much better and more in depth review, see this review on Pascal's Bookie (a new blog I hope you check out by a friend of mine).

I didn't really want to write a blog post reviewing the movie, though - I thought it was funny, and that's about it. Then I found a review of Religulous on the Catholic League's website. Well, I can't turn down an opportunity to criticize that.
[....]it is pure nonsense to play Catholicism off against science. After all, were it not for the role of the Catholic Church, there would have been no Scientific Revolution and no early breakthroughs in astronomy.
Did I miss the part of the movie where Maher "played Catholicism off against science"? If anything, Maher shows that Catholics are much more reasonable when it comes to science - he mentions that they believe in evolution and interviews an astronomer/reverend who works for the Vatican (one of the few interviews in the movie where the interviewee comes off sounding quite reasonable).
Equally dumb is the assertion that the Ten Commandments are flawed because they don’t speak to child abuse, rape and torture. Had Maher gone to more religion classes, he would have learned that the central taboos listed are umbrella strictures that cover a host of subsidiary sins.
It's true that, under Catholic theology, the ten commandments are seen as just the general structure of their ethical system. However, this misses the point - Maher was pointing out the absurdity of the commonly held beliefs about what the 10 commandments say (that they literally just restrict 10 different things). Even taken to be a criticism of Catholic theology (which I don't think it was ever meant to be) , I think Maher still has a point. Most of the commandments are irrelevant to modern law - commandments 1 through 4 can't be construed to be used in modern law (the fourth commandment, in the most charitable interpretation, tells you to follow the state's law - not exactly useful, it wouldn't make sense to make a law that says you have to follow the law).
More important, if Jesus is not the Son of God, as Maher contends, then why does he waste time—and make himself look silly in the process—by invoking Jesus’ name to give homosexuality a pass? In the flick, Maher argues that homosexuality couldn’t be so bad if Jesus never mentioned it.
Maher was making a point - assume, for a moment, that Christianity is true. Then why care so much about homosexuality? Jesus didn't seem so concerned about it. It was a reductio ad absurdum.
And, of course, Maher’s contention that religion kills looks rather feeble given that the 20th century was the most violent in history.
Recent history doesn't change earlier history, does it? Religion continues to kill today, and the fact that there are some other causes of death and war doesn't change that (although perhaps a valid argument may be made that Maher exaggerates the dangers of religion).

What I find very interesting about this statement about Religulous is more about what is left out than what is in it. The only criticism Maher levels specifically at Catholicism is that the grandeur of the Vatican seems contrary to Jesus' message about the rich and poor. The Catholic League's statement conveniently leaves this out. They seem much more bent on attacking the criticisms that weren't even directed at them.

Comics I Enjoy

XKCD

A pretty nerdy comic about math, science, and the internet. As a computer science major I find this comic particularly amusing as many of the comics refer to concepts in math, logic, or computer science. The humour tends to be hit-and-miss.

Some of them that I find particularly amusing:

Centrifugal Force
Fetishes (this probably isn't funny to about 99.9% of the population, but I find it hilarious)
Beliefs (okay, so this isn't the funniest XKCD, but I had to post this one for its content)

Cectic

A skeptic comic. Possibly my favourite webcomic of all. Common themes are religious skepticism (or lack thereof), conspiracy theorists, and "alternative medicine". Unfortunately it isn't updated frequently anymore, but it is still active. It's pretty consistently hilarious.

Ones I find particularly amusing:

ScientLOLogy
sry guyz my brain d/ced
Conclusive Proof

We The Robots

A comic about robots! Common themes are skepticism and office life.

The True Meaning of Christmas
An Atheist, Damned to Hell
Introduction, Chapter 002

Saturday Morning Breakfast Cereal


I don't even know how to describe this comic. Instead let me just give a sample of ones I find funny (they don't have names so I had to make them up!):

A Religious Look at the Origins of the Universe
The Most Elegant Language Ever Created (computer programming joke, but I think anyone can appreciate it)
Finished Building the Universe

I approve of this website

This is one of the best t-shirt sites I've ever come across. It makes me happy.

Sadly, I am receiving no money for plugging this site.

Maybe I should just stop it...

For anyone wondering, the young theist from earlier posts has not gotten back to me since my last message (which was sent over a month ago and is quoted in my earlier blog post). However, recently I have been trying to start correspondences with many different theists to see the kinds of explanations I get from them. Often I am just trying half-heartedly, as it seems pointless. After this latest one, I really feel like maybe I should just stop - I am not getting the answers I want and these conversations are just depressing me.

He started out sounding fairly intelligent. Very few grammatical mistakes, good grammar, and laid out his case fairly concisely. Things went downhill quickly from there, though. After explaining a strong piece of evidence for the common ancestory of humans and other apes, the telomere-telomere fusion of chromosome 2, this theist responded:

It's a common cop-out that evolutionists make, to try to psycho-analyze God. They claim that we have to understand the mind of the designer before they will admit that design exists. [....]

You have answered the way that every evolutionist I've spoken with does...you didn't answer my question and give me a piece of EMPIRICAL evidence proving evolution true. Empirical evidence is not "why else would it be this way." Empirical evidence is "this observable fact proves that it cannot be any other way." It's funny how many evolutionists don't understand the difference between scientific proof and assumption. They somehow think there is a difference between creationism and evolution, without realizing that both are belief systems. If there was empirical evidence for evolution, the theory of evolution would be the law of evolution. If there were empirical evidence for God, belief in God would be replaced with the scientific law of God, and I could show it to you. But faith is required.
It also appears you're assuming yourself greater than God, if you are laying down the terms by which you will accept him (insisting to know why the numbers of chromosomes are the way they are before you will believe). If God is real, then he is greater than us, and we must capitulate to him, not vice versa.

Err... Okay, so no matter how much the evidence points towards evolution, since a god could in theory have made things that way and we can't know the mind of god, there can't be any evidence for evolution! Amazing... This is worse than the person who claims dinosaur fossils were put there by god to trick the unfaithful, because this guy won't even give a possible explanation.

He then went on (after claiming I refused to tell him my objections to god, though I had tried to as best as I could explain why I thought god was unlikely) to say this:

If evolution is true, then you and I are just accidentally-glorified globs of dust, and there is no objective reason for one glob of dust to care what any glob of dust believes about its origin. The fact that you and other evolutionists strongly argue the evolutionary viewpoint proves that at least something in an evolutionist doesn't believe that evolution is true. It would be inconsistent with an evolutionary worldview for an evolutionary-believing glob of dust to care so strongly about whether the ideas of a creationist-believing glob of dust were "right" or "wrong", when the very concept of "right" and "wrong" is contrivance made up in the minds of globs of dust. Once the globs of dust die, they lose their memory, and have no recollection of whether they were "right" or "wrong" about what they believed. So why even discuss it, if evolution were actually true? If evolution is true, why fight so strongly against intelligent design in the school systems? If we globs of dust blow ourselves to kingdom come with nuclear weapons, so what? Our existence was an unintentional accident in the first place, and therefore has no objective value worth preserving. These are the necessary correlaries of evolutionary theory, yet I have never encountered a person who truly believes these correlaries, or who fully acts in a manner consistent with them.
*facepalm*

By the way, if any theists are reading this and think they are being represented unfairly by their fellow believers, feel free to speak up, either in the comments or in an email to me.

The Limits of Argumentation

Yesterday I was putting together a bunch of arguments against theism and rebuttals to common theist arguments for use by a friend in a debate. When I was done, I started considering the arguments and I just felt empty. Somehow, all of the arguments on either side just seem to completely miss the mark.

I doubt that many (if any) people believe in a god because of Pascal's Wager. Why, then, is it such a common argument? It seems to me it is a nice way of rationalizing belief. On the flip side, how many people disbelieve because of the problem of evil? Perhaps a fair number of people have deconverted from their religion because of it, but I don't think this even comes close to being an explanation as to why atheists, in general, don't believe.

I, as an atheist, find gods hard to believe in because they don't see a way for a god to coherently sit in the universe. An omnipotent, omniscient being that cares about humans seems absurd - it would have to be extremely complex to be all the things theists claim it is, and it seems far too anthropocentric to believe the creator of the universe (which we inhabit a fraction of a tiny speck of) cares specifically about us. This makes the claim that a god exists an extremely extraordinary one. The fact is, we would need really good evidence for this claim. This seems to be a fairly common way of thinking with atheists.

Let's take the other perspective now. I think at the base of much of theism is this idea that mind is a fundamental property (like mass or volume). It can't be broken down, and some things just have mind. I think when looked at this way, the god hypothesis becomes pretty appealing - gods don't have to be complex, they are just really big (or infinite) minds. Since mind is a fundamental property (according to this idea), it doesn't seem strange that there would be a giant mind - perhaps mind is just the most fundamental of essences. Of course a really big mind would care specifically about us, because we have minds too! Suddenly the god claim doesn't seem like such a huge claim. The god hypothesis seems to explain so much, so it seems adopting it makes the most coherent sense out of the universe - not only does it explain the big questions of how the universe began and why we exist, but things like free will, morality, death, etc. all are easily explained (again, according to this view). Of course, we should keep in mind there are also social factors and psychological biases that affect beliefs in the supernatural as well (and are very likely the causes of the theist worldview in the first place), but they aren't my subject here.

I think these are more or less the positions of most atheists and theists when they meet each other in a debate. They then carry on debating about evidence, but it would take a huge amount of evidence for the theist to convince any atheist, and the atheist would have to undermine a theist's understanding of many different concepts (morality, free will, etc) which have become integral to the theist's understanding of the universe. It frequently happens that people (atheists and theists) are amazed that people with views differing with theirs will be unwilling to change their views in the face of what seems to them to be a perfect argument.

Debating is good - maybe you will get someone watching thinking, or maybe you'll convince some fence-sitters (plus, debating is fun!). But as Daniel Dennett has said, the idea that you can disprove god's existence in order to convince everyone there is no god is a quixotic notion. I think a much better way of getting people to reject faith is to provide natural explanations which undermine theists' view of the world. Dennett himself has tried this by calling for a natural explanation for the origins of religious belief itself. Owen Flanagan does a very good job in The Problem of the Soul of trying to explain why people shouldn't be worried about a naturalistic explanation of the mind - we can still have all the good stuff people think the soul gives us, but without the metaphysical weirdness of the soul.

I think that education - particularly in cultural studies, history, psychology, cognitive science, critical thinking and biology - are all much more effective in undermining the average theist's position than argumentation could ever be.

Thoughts?
