Questions Frequently Asked of James Randi on myriad topics

In two earlier
blog posts, I mentioned that the James Randi Educational Foundation has offered one million dollars for proof of supernatural phenomena. Frauds and deluded folks have frequently repeated similar excuses to one another over the years, in efforts to either avoid being tested for supernatural feats they claim they can do, or in efforts to explain away their failure to pass a test that they agreed beforehand was fair. Now Randi has a list of questions that have frequently been asked about the JREF million dollar challenge.

More Rebuttal to "Tale of the Slave" / Sorites Paradox

In a recent post, I cited Nozick's parable, Tale of the Slave. Below is another rebuttal to Nozick's parable.

It took me more than 6 tries to get the following URL to work, so I will post the URL and the key points. I hope I do not violate the author's copyright by quoting the key part of it.
A Short Note on Nozick's "Tale of the Slave"

J. Bradford Delong wrote:
-------Begin DeLong Quote-------
There are, of course, two things that make this argument of Nozick's deceptive and objectionable:


1) The (false) implicit claim that there is a sharp dividing line separating "slavery" from "freedom," and that differences within the classifications are unimportant.
2) The (false) implicit claim that there are only two choices: Nozick's minimal state on the one hand, and a pure majoritarian dictatorship on the other. You have to go a long way beyond Nozick's #9 to get to anything that approximates what we have in America today.

One of the responders to this on DeLong's web page pointed out that DeLong's first point is akin to pointing out Sorites Paradox.

According to the October 2006 Wikipedia article, Sorites Paradox

-------Begin Wikipedia Quote-------

is a paradox that arises from reasoning with predicates which seem not to have a sharp cutoff, such as 'bald', 'tall', and the like.
For instance, it seems plausible that no heap of sand will stop being a heap just because one grain of sand is removed. This, however, leads to seemingly odd results.
1. One million grains of sand make a heap.
2. If some collection of grains of sand make a heap, then that collection minus one grain will still make a heap.
3. So, 999,999 grains of sand make a heap.
Repeated applications of premise 2 (each time starting with one less number of grains), will eventually allow us to arrive at the conclusion that 1 grain of sand makes a heap. On the face of it, there are three ways to avoid that conclusion. Object to the first premise (deny that one million grains makes a heap, or more generally, deny that there are heaps), object to the second premise (it is not true for all collections of grains that removing one grain cannot make the difference between it being a heap or not), or accept the conclusion (1 grain of sand can make a heap). Few, if any, reply by accepting the conclusion.

I found this to be a persuasive argument that Nozick's "Tale of the Slave" is less than it appeared to me at first. I still think that there is validity to the notion that we are less free than we ought to be, and that a pure democracy without guarantees of rights is not desirable, and that being allowed to vote in a large-enough group is little different in terms of changing results than being disallowed to vote, probabilistically speaking.

The Significance of the Octopus

The Significance of the Octopus: A dreamlike vignette or a haunting prose poem?

This one gets me right there.

The Tale of the Slave

This next parable made a strong impression on me for years, but I heard some rebuttals that got me thinking.

The Tale of the Slave

Here's the lesser of the rebuttals.

A response to libertarians and anarchists regarding the tale of a slave

And here's the preparation for the better of the rebuttals.

Grandpa Japan (Sero-Ojiisan)

This link requires a high speed connection. This is a magician from Japan. The first brief scene shows the youthful magician getting aging makeup. After that he has a few very clever close up magic acts. Understanding Japanese is not required, except that when he is on the passenger train, he repeatedly asks for tea just before reaching for the iced tea ad near the ceiling of the train.

Sagan and Nuclear Winter (Lies that Got Believed, part 2)

I was a fan of Carl Sagan's Cosmos science TV series. But heroes make mistakes and heroes have character flaws.

Sagan and Nuclear Winter (Lies that Got Believed, part 2)

Vangelis did the eerie and beautiful music to that series.

Lies that Got Believed, part 1

Lies that Got Believed (Nuclear Winter. Scholarly Paper Presentation Methods influence results.)

Here's a snippet

"My guess is that they were telling the truth about their analysis. They may even have been correct in their conclusion. But the degree of uncertainty implied by that article was strikingly inconsistent with the confidence with which the nuclear winter conclusion was being trumpeted--largely by people who wanted other people to believe it because they thought that belief would reduce the risk of nuclear war."

Monkey Tuesday Theme Lyrics

Definitely not in the category of Ideas Worth Reading, but I wanted to share
my delight anyway.

I wrote lyrics to a tune I'd heard on Penn Radio and emailed the lyrics in.

They played it on the radio. I was so delighted I jumped up and lept about.

Penn Radio on Tuesdays features folks calling in with stories about monkeys and mayhem. Whenever the host says "monkey Tuesday" the staff plays the Monkey Tuesday theme.


Monkey Tuesday Theme Lyrics
by David Oakey

monkeys on the air
monkey with the mike
screeching scratching biting
that we like

don't say chimpanzee
nor orangutan
all we say is monkey
bang bang bang

monkeys in the air
monkeys on the roof
tearing off the landau
wif their toof

now they have the pots
now they have the pans
let's go ape together
bang clang cans

Note: the "Monkey" in the second line is a verb, not a noun, and "Mike" could either be Michael Goudeau, the show's cohost, or microphone.
