Tuesday morning logic games

Oy. It's too early in the morning for logic, but Mrs Tilton just had to prod me with a link to this theological argument:

Think about it: what are the chances that a media whore like Gannon would turn out to be an actual whore? It's impossible. It boggles the mind how infinitely unlikely this is. It's like if you found someone pirating CDs, and it turns out he actually had a peg leg and a parrot on his shoulder and sailed around the Caribbean saying "arrrrrr!" and plundering booty. You wouldn't believe it. But there it is: impossible, but true. Impossible truths are miracles, and only God can work miracles. Ergo, God exists. Q.E.D.

I'm sorry, but there's nothing revolutionary or in the least bit novel about that, although I always appreciate philosophy that throws in a pirate or two. All theology sounds like that to me…"umpty-tumpty squigglety-poo, therefore God." Man, if you want those kinds of laughs, you don't have to read The Poor Man, just crack open your Bible.

Wouldn't you know it, though, at the same time that Wilkins fella is playing logic games (it's understandable, though, and so we should forgive him; he is a philosopher, you know.) He's gone and invented a new logical operator, the floogle, to describe another common line of argument.

Floogle is the "possibly-therefore-true" operator. It is possible that life was made by an intelligent design (despite the complete lack of any reason to think so), therefore it was. It is possible Iraq had WMDs, therefore they did. It is possible that Clinton was a sleeper spy for the Communist Chinese, therefore he was. And so forth.

Here's the floogle: logical operator

And here's its use:

Possibility logical operator God

The symmetry with the Poor Man's argument is obvious. Not being one to allow Wilkins to steal all the glory, I have therefore invented a complementary operator, the thingumagod.

Impossibility logical operator God

These together will allow us to compress all religious arguments about the existence of god into a series of floogles and thingumagods, thereby both shortening the discussion and making it immediately apparent that it is all a lot of fatuous twaddle. (We may also need a non sequitur operator to be truly complete, but I will leave invention of that one as an exercise for the reader.)


I've also invented another operator (wow, but logic is so easy!)

logical operator

It's a unary operator that negates the previous two operations. I call it the bullpoop.

"Impossible" things happen all the time, if by "impossible" we simply mean things that seem to defy some intuitive sense of probability we all seem to possess. Somewhere at home, I have a mathematical formula (based on the volume of the earth's atmosphere and the average human VO2) that purports to show that the odds that some of the air in your lungs right now having once been in the lungs of Jesus Christ approach total certainty - something like 0.998.

The world is a weird place, even without God.

Eh, well, if I am perfectly honest, I didn't really think that would persuade you to come down to the altar. (Nor do I think it a sound argument, although it's just barely possible that The Editors did not mean it seriously.) I just thought: if there's one argument for the existence of God that PZ would enjoy reading, it's got to be this one.

How'd you find the permalink, BTW?

If you use the comments link and cut the anchor thingamajig off it (the # and everything after it), it will work as a permalink.

Yeah, not a very good argument at all. Entertaining though...

My first thought when I read the Poor Man's argument was that someone hasn't been keeping up with their Douglas Adams:

The argument goes something like this: “I refuse to prove that I exist,” says God, “for proof denies faith, and without faith I am nothing.”

“But,” says Man, “the Babel fish is a dead giveaway isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.”

“Oh dear,” says God, “I hadn’t thought of that,” and promptly vanishes in a puff of logic.

I think too many people are taking The Poor Man seriously! I present to you this fragment.


I asked him to explain the grand strategy for victory in the war on terror, liberals, and the MSM.

“The situation is thus: one on side, we have the Enlightenment; on the other, Islamofascism,” explained Wretchard. “The paradox at the heart of this conundrum is that these are both two sides of the same coin: one light, one dark. The liberal-terrorist enemy cannot see this, because he is bound in the duality which sustains him, but which will ultimately destroy him. But that is only an illusion, for indeed, the two are like the two sides of a Mobius strip; looked at closely, quite distinct, but, from a far vantage, revealed to be the same, shifted only in phase, one eternally blending into the other. This Mobius strip is tied into a Gordian’s Knot, which must be severed. It is in this way that the ultimate historical paradox will be resolved.

“Now, save against Dragon Breath.”

“Heh. Indeed,” remarked Reynolds. “Read the whole thing.”

Looks more like the "Lost Toupee" operator.

Floogle-- isn't that the operator formerly known as Prince?

Today, instead of blowing my 10 - 12 free time window on blogging, I'm going to the gym. However, since I feel like it'd be a shame to blow our posting-every-weekday streak, I bring you new logical operators from one...

You mean kind of like the argument, "it's possible that everything happened randomly, therefore it did"?

(Note: evolution does not in any way require randomness; all it requires is gradual change following the rule, "whatever tends to make itself more common is usually more common". The idea that there's some unintelligent causitive agent (or agents) behind why the particular variations which crop up is a different idea entirely from evolution.)



#16142: — 02/15  at  09:22 PM
I am a regular reader of The Poor Man, and without question The Editors were joking. That, more than anything else, is what The Editors do.

Not quite, but you're almost there. Phenomena behaving according to the blind whims of the observable laws of the universe (or, as you call it, "randomly"), is a logical a priori assumption in the absence of evidence to the contrary. Jehovah or Allah or Shiva have not been observed to exist, and as such don't enter into the equation. Although you're free to keep looking.

Along those lines...

...all [evolution] requires is gradual change following the rule, “whatever tends to make itself more common is usually more common.”

Well, not if whatever (allele) makes itself common is disadvantageous.

Your "rule" is obviously looking at the individual (or species?) for the site of selection, but it is likely that evolution takes place at the level of genes (see Richard Dawkins).

Regardless, your "rule" is not a rule at all. It's an observation in hindsight. An observation, by the way, which also happens to work well with a would-be intelligently designed biodiversity...

...or, any other model for anything else.

In fact, it's more of an ontological statement (about the existence of stuff) than anything else.

But, by all means, continue to convince yourself otherwise if that makes you feel better, or if you actually think your God wants you to know less about the world around you.

Once in a while you get shown the light, in the strangest of places if you look at it right.

I love the operators! But just to be a techy geek, they're not so much operators as they are rules of inference. E.g. from

1) It is possible that God exists.

Floogle allows you to infer (conclude):

2) God exists.

Alternatively, you might want to take them as axioms. Then from

3) The floogle axiom: For all P, if P is possible, then P.

and

4) It is possible that God exists.

One could just use the inference rules of Universal Instantiation and Modus Ponens to infer (conclude):

5) God exists.

I would also like to add my own rule of inference. It's called "Modus Iwannit". From

6) I want God to exist.

it allows you to infer

7) God exists.

Dear d locke (any relation?)

Your confusion is apparent. The floogle is only an axiom in a formalistion in ordinary logic. But in flogic, it is a primitive operator. I hope this helps.
