The logic of science-1: The basic ideas

(For other posts in this series, see here.)

In the course of writing these blog posts, especially those dealing with religion, atheism, science, and philosophy, I have often appealed to the way that principles of logic are used in science in making my points. But these are scattered over many posts and I thought that I should collect and archive the ideas into one set of posts (despite the risk of some repetition) for easy reference and clarity. Besides, I haven’t had a multi-part series of posts in a long time, so I am due.

Learning about the principles of logic in science is important because you need a common framework in order to adjudicate disagreements. A big step towards in resolving arguments can be taken by either agreeing to a common framework or deciding that one cannot agree and that further discussion is pointless. Either outcome is more desirable than going around in circles endlessly, not realizing what the ultimate source of the disagreement is.

Livening up the fourth

Over at National Review Online, Dennis Prager has come up with an exciting new ritual to liven up that dull holiday known as the fourth of July that he hopes will instill in young people a better understanding of the true meaning of the event. He says he based it on the Passover seder and we know that there is nothing that children like to do on a holiday more than engage in solemn quasi-religious rituals instead of running around outside eating hot dogs and watching parades and fireworks. Here’s a sample of Prager’s ritual (I am not making this up):

Host holds up each symbolic item as he explains its symbolic meaning.

  • We drink iced tea to remember the Boston Tea Party. “No taxation without representation” was the patriots’ chant as they dumped British tea into the Boston Harbor.
  • We eat a salty pretzel to remember the tears shed by the families who lost loved ones in the struggle for freedom in the Revolutionary War and all the wars of freedom that followed.
  • We ring a bell to recall the Liberty Bell, which was rung to announce the surrender of the king’s army. On the Bell are inscribed these words from the Book of Leviticus: “Proclaim Liberty throughout all the Land unto all the Inhabitants thereof.”
  • We eat strawberries and blueberries dipped in whipped cream to celebrate the red, white, and blue of our flag.

Once this gem hit the internet, there was much merriment in the land, courtesy of Tbogg and James Wolcott.

Letting torturers go free

The slide into lawlessness by successive US administrations has been aided by the courts which have been cowed by the ‘war on terror’ to essentially give carte blanche to the administration to do whatever it claims it needs to do to ‘keep us safe’. For example, it was ruled that Jose Padilla could not even sue Donald Rumsfeld and others who were responsible for the brutal treatment he received. The Obama administration has continued the process, covering up its own crimes and those of its predecessors while making token gestures towards upholding the rule of law.

On the pursuit of happiness

On this independence day holiday, I am repeating a post on what to me is one of the most intriguing phrases in the US Declaration of Independence. It is contained in the famous sentence:

We hold these truths to be self-evident, that all men are created equal, that they are endowed, by their Creator, with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.

I have always found the insertion of the phrase “the pursuit of happiness” as an inalienable right to be appealing. One does not expect to see such a quaint sentiment in a revolutionary political document, and its inclusion sheds an interesting and positive light on the minds and aspirations of the people who drafted it.

While happiness is a laudable goal, the suggestion that we should actively seek it may be misguided. Happiness is not something to be pursued. People who pursue happiness as a goal are unlikely to find it. Happiness is what happens when you are pursuing other worthwhile goals. The philosopher Robert Ingersoll also valued happiness but had a better sense about what it would take to achieve it, saying “Happiness is the only good. The place to be happy is here. The time to be happy is now. The way to be happy is to make others so.” [My italics]

Kurt Vonnegut in his last book A Man Without a Country suggests that the real problem is not that we are rarely happy but that we don’t realize when we are happy, and that we should get in the habit of noticing those moments and stop and savor them. He wrote:

I apologize to all of you who are the same age as my grandchildren. And many of you reading this are probably the same age as my grandchildren. They, like you, are being royally shafted and lied to by our Baby Boomer corporations and government.

Yes, this planet is in a terrible mess. But it has always been a mess. There have never been any “Good Old Days,” there have just been days. And as I say to my grandchildren, “Don’t look at me, I just got here.”

There are old poops who will say that you do not become a grown-up until you have somehow survived, as they have, some famous calamity — the Great Depression, the Second World War, Vietnam, whatever. Storytellers are responsible for this destructive, not to say suicidal, myth. Again and again in stories, after some terrible mess, the character is able to say at last, “Today I am a woman. Today I am a man. The end.”

When I got home from the Second World War, my Uncle Dan clapped me on the back, and he said, “You’re a man now.” So I killed him. Not really, but I certainly felt like doing it.

Dan, that was my bad uncle, who said a man can’t be a man unless he’d gone to war.

But I had a good uncle, my late Uncle Alex. He was my father’s kid brother, a childless graduate of Harvard who was an honest life-insurance salesman in Indianapolis. He was well-read and wise. And his principal complaint about other human beings was that they so seldom noticed it when they were happy. So when we were drinking lemonade under an apple tree in the summer, say, and talking lazily about this and that, almost buzzing like honeybees, Uncle Alex would suddenly interrupt the agreeable blather to exclaim, “If this isn’t nice, I don’t know what is.”

So I do the same now, and so do my kids and grandkids. And I urge you to please notice when you are happy, and exclaim or murmur or think at some point, “If this isn’t nice, I don’t know what is.”

Good advice.

People don’t realize how much they rely on government programs

It is now the fashion to claim that the government should stay completely out of people’s lives and that we should manage on own own. What many of the people who make such claims do not seem to realize is that they are the direct beneficiaries of many government programs.

Steve Benen points out a chart shows the enormous number of people who say they have not used a government social program who have in fact benefited in some way or other.

This kind of cluelessness is only possible because, unlike the private sector, the government rarely broadcasts the fact that they are giving you a benefit. The public works signs that say “Your tax dollars at work” may be the only exceptions.

The most obtuse of such people may be the actor Craig T. Nelson who in a TV interview with Glenn Beck condemned government aid to the poor as coddling, giving himself as an example of someone who heroically struggled through difficult times entirely on his own. “They’re not going to bail me out,” Nelson said. “I’ve been on food stamps and welfare. Anybody help me out? No. No.”

Astute observation …

… from Paul Krugman:

[T]he surest way to get branded as not Serious is to figure things out too soon. To be considered credible on politics you have to have considered Bush a great leader, and not realized until Katrina that he was a disaster; to be considered credible on national security you have to have supported the Iraq War, and not realized until 2005 that it was a terrible mistake; to be credible on economics you have to have regarded Greenspan as a great mind, and not become disillusioned until 2007 or maybe 2008.

Why must we buy shoes in equal-size pairs?

Apparently 60% of the population have left and right feet that are of different sizes, and of those 80% have larger left feet, which apparently has something to do with right hand dominance. (I got this information after a quick search from this website but cannot vouch for its reliability.) So that means that 40% of the general population have feet of equal size, 48% have larger left feet, and 12% have larger right feet.

I belong to the larger left foot group. When I buy a new pair of shoes, if I forget to try it in the store with my left foot, I end up with a pair in which the left foot starts to feel pinched and uncomfortable later in the day when people’s feet start to swell. For some, the inequality is so great that they buy two pairs of shoes in two different sizes and use only one of each, which seems like a colossal waste. As a partial and somewhat clumsy solution, this website offers people a way of exchanging unused mismatched shoes.

But why must shoes be sold in equal size pairs at all when this does not suit the needs of more than half the population? Why not allow people to pick the correct size for each foot? Doing so should lead to little or no waste, even if 100% of the population had the same side foot being larger. For example, if I needed a size 11 left shoe and a size 10 for the right, someone else with a larger left foot would need a size 10 left and a size 9 right, and so on. So all the mid-range sizes would be paired off and sold, except to different customers.

There may be a few left over of the largest right shoe sizes and the smallest left sizes but assuming the above distribution is right, a quarter of those would be bought by people with larger right feet, leaving only a few unsold. And over time, manufacturers would be able to estimate production more accurately and eliminate even this waste.

So shoe manufacturers and retailers, what about it?
