Extraordinary Claims

Extraordinary claimsAs the poster for the Centre for Inquiry notes, extraordinary claims require extraordinary evidence. It’s a popular catchphrase for the skeptical movement, but should be an intellectual policy for everyone.

Regardless of what is being claimed, it requires evidence at the same level of the claim.

Anecdote is not evidence, please note, especially personal anecdote even with the corroboration of other witnesses. People often “see” what they choose to see, and interpret events and objects according to preconceived ideas. Seeing UFOs instead of ordinary aircraft, or chemtrails instead of mundane contrails are examples of this. Evidence is something concrete; a body of facts, not simply interpretation or disingenuous claim.

The Centre lists many claims as the poster indicates – a list that continues to grow – along with a brief introduction to each: claims, evidence and conclusion. Some like leprechauns, the Easter Bunny, tooth fairy, dragons and Xenu seem pretty obviously mythological or (like Xenu) totally fabricated. Others will certainly raise an argument among some religious believers  or the superstitious – angels, magic, Heaven, hell, the afterlife and similar religious topics included (it does not yet list Santa Claus, but I expect it will come)..

As RationalWiki puts it,

Extraordinary claims require extraordinary evidence was a phrase made popular by Carl Sagan. It is central to scientific method, and a key issue for critical thinking, rational thought and skepticism everywhere.

The actual phrase was coined by sociologist Marcello Truzzi, but it has been around in other forms for several centuries. In his 1748 work, An Enquiry concerning Human Understanding (chap. 10.4.), David Hume wrote:

In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence… No testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous than the fact which it endeavors to establish.

Simply because a lot of people believe in something, or accept it as factual doesn’t mean it is true. In a letter to Adam Smith, Hume wrote:

Nothing indeed can be a stronger presumption of falsehood than the approbation of the multitude…

Conrad Black: Off the Rails

Conrad BlackI generally read Conrad Black‘s columns for their entertainment value, but I also read them for the language. Black is the best tosser of pithy epithets since Spiro Agnew*. And like the former US VP, he’s a pompous git who puffs up his intellectual feathers like a pigeon in heat – that puffery of sound and fury that signifies nothing more than an ego he has to bring along in its own carriage. He is very amusing that way.

Now to be clear, I have little respect for Black’s uber-right ideologies. We are at polar opposites of the political spectrum: as a self-appointed spokesperson for the entitled one percent he annoys my modest socialist and humanist values.

And because  I also value loyalty to my native Canada, I detest that he gave up his Canadian citizenship in such a cavalier fashion. (I suggest strongly that he be tossed out of the country for that and because he’s also a criminal: he was convicted of fraud in the USA and served jail time for it. Criminality is another similarity he shares with Spiro Agnew, although the circumstances differ.)

But being a criminal doesn’t mean he can’t write. Damn, but he often turns a mean phrase and, even if I disagree with his haughty self-absorbed and pretentious politics, I like to read him because he wordsmiths brilliantly. Most of the time. Sometimes, of course, he’s just that pompous, self-righteous git we all loathe.

This past week, Black outdid himself in his NatPost column and took that pomposity and git-ness to a new level.

The piece was titled “The shabby, shallow world of the militant atheist,” and in it Black railed like a frothing Irenaeus against the likes of Richard Dawkins and Christopher Hitchens. Perhaps Black – who professes to having having his his prison sentence made endurable through his faith – is planning his new book; a 21st century version of Against the Heresies.

Black writes…

Nor can the atheists ever grapple plausibly with the limits of anything, or with the infinite. They rail against “creation” — but something was created somehow at some point to get us all started. They claim evolution debunks Christianity  (though all educated Christians, including Darwin, acknowledge evolution) — but evolution began somewhere. When taxed with the extent of the universe and what is beyond it, most atheists now immerse themselves in diaphanous piffle about a multiverse — but the possible existence of other universes has nothing to do with whether God exists.

I love that phrase, “diaphanous piffle…” although it exposes his ignorance. I was disappointed, because if nothing else, I always thought Black was well-educated. Clearly his education in cosmological concepts and quantum mechanics is less than that of the average scifi reader. Why must there be anything beyond this universe? Why can’t this be everything?

And as for evolution: of course it started somewhere but there is no reason to believe it is the result of divine intervention. We’ve created organic molecules in the lab; we’ve found them on comets and other moons. Life just got its start through nothing more exotic than chemical reaction. And who claims evolution debunks Christianity? The creation myths are in Genesis, not the New Testament. Such claptrap.

Richard Dawkins tweeted in response to Black’s column:

Spot the factual errors, illogicalities and failures to understand.

Reading Ukulele Tabs

Smile tabbed by Mike LynchOne of the things I want to discuss in our upcoming CPLUG workshop is how to read tab sheet music. In this post I’ve give you some pointers so you can practice on your own. It’s worth learning to read tabs because it gives you the ability to play melodies and solo pieces without having to read music.

Don’t be confused when you see a piece labelled “tab” but only showing the lyrics and chords. The name is often used for that purpose, although it’s not really a tab in the proper sense.

First you’ll need a properly tabbed song to work with. For this exercise, I’m going to use Charlie Chaplin’s song Smile, tabbed for ukulele by Mike Lynch. you can click on the image of page one at the upper right and download the PDF from his site. Mike offers a number of ebooks for sale on his site, as well as online ukulele lessons. This lovely piece is from his Ukulele Solo Instrumentals book, a collection of 52 songs. He also has two chord melody books. I’ll discuss chord melody techniques in another post, but what you learn here works with them, too.

Mike’s tabs are more comprehensive than some: he includes both the music staff and the tab, below, plus the words. Not all arrangers include the actual music. You can also see the chord names above the staff. Mike links the music notes on the staff with the string/frets on the tab with a vertical line – this can be helpful if you’re trying to learn to read music.

Let’s take a look at some of the parts of this song. First the start:

Smile 01

Smile 01What does this tell us? The music staff tells us this song is in the key of F (one flat – the ‘b’ sign) and is in 4/4 time. The first chord, shown above the staff, is F. Quite often the first chord is also the song’s key, as it is here. The F chord on the ukulele looks like the diagram on the right. This is also written out as 2010 which identifies the strings and frets, reading from the fourth string (leftmost) to the first.

2010 means: put a finger on the second fret of the fourth string, and another on the first fret of the second string, and play the other two strings open (0). These are the notes A-C-F-A, reading left to right (fourth to first strings). For those of us with re-entrant tuning (high G), the A on the fourth string is actually an octave too high for the note shown in the staff.

If a string should be dampened or not played, it is usually marked with an X. Now turn that diagram 90 degrees counterclockwise and you’ll see how tabs work.

Manufactured Terror: Bill C51

Stephen Harper wants you to be afraid. VERY afraid. If you’re frightened, you likely won’t question his and his party’s destruction of the country, the decaying economy, job losses, homelessness, the ignored murder of aboriginal women, the muffled and cowed bureaucracy, hobbling the CBC, undermining Canadian science and scientists, and our waning credibility on the world stage.

And if you’re scared, you certainly won’t challenge him or his party over the introduction of Bill C51 – ostensibly an “anti-terrorism” bill but one that threatens to take away your rights and advance Harper’s private agenda.

And, of course, it’s his tactic for winning the next federal election: by appearing Canada’s sole defender against the boogeyman of terrorism, while tarring his opponents with the epithet “soft on terror.”

But while all Canadians are concerned about the threat terrorist post to our society, our institutions and our way of life, it seems few of us think Harper’s Orwellian, Big Brother state is worth the trade. Some of us even wonder why the bill seems to ignore the growing cyber-security threats from Asia and Russia, and focus so much on Islamist extremists.

Harper has been accused by opposition leaders of fostering intolerance towards Muslims:

Tom Mulcair accused him of fostering “intolerance” and helping create “Islamophobia.”
Liberal leader Justin Trudeau, who began the attacks earlier this week by accusing Harper of spreading “fear” and “prejudice” of Muslims, jumped into the fray again on Wednesday.

But in reality, all Canadians should be worried by this bill. As the Globe and Mail noted in an editorial in February, “Anti-terrorism bill will unleash CSIS on a lot more than terrorists…”

Why does the bill do so much more than fight terrorism? One part of Bill C-51 creates a new definition of an “activity that undermines the sovereignty, security or territorial integrity of Canada” that includes “terrorism,” “interference with critical infrastructure” and “interference with the capability of the Government in relation to … the economic or financial stability of Canada….”
So what is this other class of security-underminer the bill refers to? A political party that advocates Quebec independence (there goes our “territorial integrity”)? Indian activists who disrupt a train line? Environmental activists denounced as radicals by a cabinet minister?
… if Bill C-51 passes, CSIS will be able to disrupt anything its political masters believe might be a threat. As the bill is currently written, that includes a lot more than terrorism.

But it’s not just Bill C-51 that’s a threat to civil liberty. The government also has Bill C-44, the Protection of Canada from Terrorists Act, in the wings. As the Huffington Post notes,

The bill would allow CSIS to seek a judicial warrant to investigate a security threat — “within or outside Canada.” The warrant could be issued “without regard to any other law, including that of any foreign state,” the legislation states.

An editorial on Rabble noted,

Bill C-44 is a systematic attempt by the government to circumvent the limits Canadian courts have placed on its investigative and surveillance powers, through legislative amendments. It expands the powers of CSIS to allow for surveillance activities in Canada and abroad, consequentially allowing CSEC to intercept, or allow other foreign agencies to intercept, telecommunications of Canadian citizens when travelling abroad.

Lucy and the 10% Brain Myth

LucyWe watched the film Lucy on iTunes last night and, while reasonably entertaining, its plot is founded on a persistent bit of pseudoscience: that people only use 10% of their brain capacity. It’s so widespread a myth that Wikipedia has a page on it that opens:

The 10 percent of the brain myth is the widely perpetuated urban myth that most or all humans only make use of 10 percent (or some other small percentage) of their brains. It has been misattributed to many people, including Albert Einstein. By extrapolation, it is suggested that a person may harness this unused potential and increase intelligence.

Sure, we all know people who don’t appear to use much of their brain’s potential power, but the simple truth is that we all use all of our brain’s capacity. We evolved a big brain to handle the growing demands of increased consciousness, speech and sophisticated motor control, and that’s what it’s for.

Sure, not all of it is used in a conscious manner. Much of the brain’s function is taken up in processing, storing and interpreting the huge bandwidth of information that is fed to it every second of every day. Even acts we do daily and take for granted – like walking upstairs with a cup of tea in one hand while talking – take a huge amount of processing power. Sight, balance, motor control, memory, logic, vocalization, muscles control… the brain takes care of it all without spilling a drop.

Your consciousness – the ego – doesn’t see all this work going on and never will because you would quickly be overwhelmed by the huge amount of data being managed by your unconscious. Yes, yes, a lot of people don’t appear to even use the whole capacity of their conscious brains – anti-vaxxers, chemtrail wingnuts, creationists and some local bloggers come to mind – but that’s just a portion of what the brain does. Critical thinking is a skill one has to acquire and practice, not an inherent brain function.

Email and Confidentiality

CouncillorA story in this week’s Connection titled “Private talk with CAO leads to Collingwood integrity commissioner complaint” sparked the following comment.

No, this is not about what strikes me as the unethical and secretive behaviour of the councillor in question and his defending that behaviour in the media as if the town’s Code of Conduct did not state at its outset that all members of council (emphasis added):

…are held to a high standard as leaders of the community and they are expected to become well informed on all aspects of municipal governance, administration, planning and operations. They are also expected to carry out their duties in a fair, impartial, transparent and professional manner.

Which it seems to me his behaviour was not any of those. Or that the code – which they all signed – also says (emphasis added):

…there are open and proper channels for decision making and approval of policy,

I do not believe having private discussions with senior staff over their employment and emailing one another to build consensus outside the public forum fits the “open and proper channels” requirement.

Or that the Code also says members will:

…conduct and convey Council business in an open and public manner so that the process, logic and rationale which was used to reach conclusions or decisions are available to the stakeholders.

Which clearly cannot be done if you hold your discussions via email or in back rooms. So far this council has not shown itself to adhere to the spirit of the Code, let alone its letter. But council’s hypocritical lack of ethics is something I’ll save for another post.

Revised Chord Wheel

Revised chord wheelI have revised my transposing chord wheel/circle of fifths tool this week. It is now a three-ring version for use by all musicians (ukulele players who want to learn music theory or work on arranging songs especially). You can click on the image on the right to download the PDF.

The outer ring shows the Roman numerals for the key. This lets you see the chords by number – uppercase is major; lowercase is minor. Turn this wheel to the I key is above the key on the middle ring. The names in dark blue are some of the chord forms you can use in that position (i.e. I: major, major seventh).

The two inner wheels show the circle of fifths, with notes for the major triads for each key in green, with the relative minors named in blue. Fifths move clockwise; fourths counterclockwise. The middle ring also shows the number of flats (b) and sharps (#) in a key signature.

The inner ring is used for the key a song is in. Turn the key so that letter points to the letter of the key you want to transpose into. The chords shown on the middle ring relate to the new key.

For example, if your song is C-Am-F-G and you want to play it in F, turn the inner ring so C aligns with F on the middle ring. A on the inner ring will align with D (which means Dm since the original was Am), F with Bb and G with C. So the new chords will be F-Dm-Bb-C. And in G it would be G-Em-C-D.

Print the pages, laminate those with the wheels, then cut them out, punch holes in the centres, and push a brass paper fastener through all three. Instructions are more fully described on page four. Page five is a larger version if you want something with bigger type. Print three copies of that page.

Please contact me if you find any mistakes on the wheels.
