In which I become Immortal

Time, according to common belief, is unending and infinite.  The Universe, but not time, began with the Big Bang.  For if time had started only with the Big Bang there was no time before the Big Bang in which to create the components thereof.  So time apparently stretches back into the infinite past.  And time will go on for ever; it stretches off into the infinite future.  Or does it? 

Some current scientific theories are suggesting that at some point in the future time ceases to exist, or perhaps becomes frozen (which seems to amount to much the same thing).  Other theories suggest that time has no independent existence anyway; it is but an artificial construct of our existence; it exists only because we are measuring it.  (There’s a mind-bending article on the science of all this in the September 2010 issue of Scientific American, but you’ll need to subscribe or buy the magazine.)

It seems to me eminently reasonable that something as intangible as time is purely a human construct.  Do animals (cats or dogs, say) measure time?  Does one not need a level of self-awareness, an understanding of self, to be able to measure time?

Logically therefore, if time has no independent existence, I am immortal.  Consider …

Before I was born (or conceived, or attained pre-natal consciousness, depending how one wishes to measure these things) there was no time.  It was not part of my existence, because I didn’t exist and therefore couldn’t measure it.

Similarly when I die, time ceases.  Again I am no longer able to measure or observe it.

Ergo I have existed for all time, and am thus, by definition, immortal.

Strange mind-bending things these scientific theories of everything!  Bishop Berkeley eat your heart out!

Quotes of the Week

Well if last week was quiet, at least on the amusing & interesting quotes front, this week has seen a glut. So here’s a selection:

I will also continue my preliminary work on Project Be-less-fat. Because I WAS working on that project and that was all going well and good, and then in the last couple of months that all dropped off a bit because there was stress and bother and worry and comfort needing to be had. I do so wish the words “Yes, it’s been dreadful, we’ve been so stressed out the weight’s simply been falling off us” ever fell out of my mouth, but I, my scales, the gym manager and the owner of our local chinese restaurant know this is very very not true. And much as I know in my clever new-brain that exercising stops me feeling sad or anxious, the only thing that I want to do when sad or anxious is curl up under a duvet and sleep, so it’s hard to balance the two.

Don’t ever show something is important to you or you feel strongly about something otherwise you will be ridiculed.
Accept all abuse without retaliating.
If someone accuses you of breaking any rules or laws – don’t rise to it and defend yourself – you’ll only end up in the wrong.
Everything you think is insulting is actually humorous and you’re the stupid one for taking it seriously – no good expecting your own comments to be taken as a joke because they won’t be.

Flora or Fauna?
Do you mean which would win in a fight, which is better company when I’m lonely, or what do I prefer to spread on my toast?

The formalism of post-selected teleportation closed time curves shows that quantum tunnelling can take place in the absence of a classical path from future to past.

Great people talk about ideas, average people talk about things, and small people talk about wine.

A well-organized society is one in which we know the truth about ourselves collectively, not one in which we tell pleasant lies about ourselves.

Good taste is the worst vice ever invented.

Give sorrow words. The grief that does not speak
Whispers the o’er-fraught heart, and bids it break.
[William Shakespeare]

Worry never robs tomorrow of its sorrow, it only saps today of its joy.

High Heels Cause Long-Term Damage says the headline.

We needed scientific research to tell us this?

Twenty years ago I had a colleague who was having serious physiotherapy because she was unable to put her foot flat to the ground, caused by spending too many years wearing 4 inch heels.

Accountability of Religious Leaders

1 Comment

Prof. Lawrence Krauss writes a typically hard-hitting column in the August 2010 issue of Scientific American. I’m not sure if the piece is available online without subscription (I have access as I subscribe to the paper version of the magazine) so here are the key paragraphs.

I don’t know which is more dangerous, that religious beliefs force some people to choose between knowledge and myth or that pointing out how religion can purvey ignorance is taboo.
[…]
Last May I attended a conference on science and public policy at which a representative of the Vatican’s Pontifical Academy of Sciences gave a keynote address. When I questioned how he reconciled his own reasonable views about science with the sometimes absurd and unjust activities of the Church – from false claims about condoms and AIDS in Africa to pedophilia among the clergy – I was denounced by one speaker after another for my intolerance.
[…]
[In] Arizona, Sister Margaret McBride, a senior administrator at St. Joseph’s Hospital in Phoenix, recently authorized a legal abortion to save the life of a 27-year-old mother of four who was 11 weeks pregnant and suffering from severe complications of pulmonary hypertension; she made that decision after consultation with the mother’s family, her doctors and the local ethics committee. Yet the bishop of Phoenix, Thomas Olm­sted, immediately excommunicated Sister Margaret, saying, “The mother’s life cannot be preferred over the child’s.” Ordinarily, a man who would callously let a woman die and orphan her children would be called a monster; this should not change just because he is a cleric.
[…]
Keeping religion immune from criticism is both unwarranted and dangerous. Unless we are willing to expose religious irrationality whenever it arises, we will encourage irrational public policy and promote ignorance over education for our children.

For my part I’m not sure which is more worrying: Krauss being shouted down at a scientific conference or the Bishop of Phoenix.  Both are very worrying.

Quotes of the Week

It’s generally been a quiet week and I’ve been doing lots of Anthony Powell Society work, hence the lack of activity and only a couple of recent quotes …

If you allow annoying people to annoy you, then you’ve allowed them to win.
[Hypersexualgirl]

Nature does not say that cats are more valuable than mice; nature makes no remark on the subject. She does not even say that the cat is enviable or the mouse pitiable. We think the cat superior because we have (or most of us have) a particular philosophy to the effect that life is better than death. But if the mouse were a German pessimist mouse, he might not think that the cat had beaten him at all. He might think he had beaten the cat by getting to the grave first.
[GK Chesterton]

Quotes of the Week

Another in the series of things which have struck me, or amused me, this week.

So look, I’m going to say this thing, and you’re going to listen and believe me because … I don’t know, why would you believe me if you haven’t believed it from anyone else? […] Because in the patient corners of your heart, you’ve ALWAYS known it’s true. It’s this:
You’re not broken. You are whole. And there is hope.

There is evidence that male babbling (what you kindly call Punditry) is a Zahavian handicap.
During both foetal development and puberty, male brains are subject to damage from hormonal processes that convert the female body and neural system into a male one (more or less). This causes males to be, on average, poor at communication. They don’t understand what they hear as well as females, can’t form their thoughts into words as well, and most interestingly, can’t think about one thing while carrying on a conversation with another human at the same time, as females routinely do.
Therefore, ability to communicate at all, let alone well, is very difficult given the handicap of this developmental brain damage. Public communication (babbling/punditry) would indicate relatively high quality for any male that could do it. Thus, all that male babbling.

The Chap Olympiad has a number of things to recommend it, apart from the variety of potential experiences. One is that its resolute promoting of amateurism, eccentric sporting and events cocks an elegant snook at the revolting orgy of corporate arrogant dullardism that infuses all major sporting events. We don’t need their cocacolaMacanike extravaganzas in citizen murdering nations. Stuff ‘em.

There are two means of refuge from the miseries of life: music and cats.

Just as we should cultivate more gentle and peaceful relations with our fellow human beings, we should also extend that same kind of attitude towards the natural environment. Morally speaking, we should be concerned for our whole environment.

Quotes of the Week

Another in our occasional series of quotations encountered during he week which have struck me.

Bodies are … I mean, what are they? They’re these sacks of bone and meat and water held together by 2 meters of integumentary tissue. They’re battlegrounds of infection and injury
[…]
A body is a life. My opinion is that bodies, lives, people who have suffered and survived are the MOST beautiful. The marks left on their skins tell us of the strength, the resilience, the power of the person. The so-called flaws of a body show you what a person has made of themselves

Real bodies, real lives, real people. Real things have scratches.

“Yeah, me Aunty Jean got me a goat, but they delivered it somewhere in Africa … unbelievable”

Let us be grateful to people who make us happy: They are the charming gardeners who make our souls blossom.
[Marcel Proust]

A mind committed to compassion is like an overflowing reservoir – a constant source of energy, determination and kindness. This mind can also be likened to a seed; when cultivated, it gives rise to many other qualities, such as forgiveness, tolerance, inner strength, and the confidence to overcome fear and insecurity.
[Dalai Lama]

Put three grains of sand inside a vast cathedral and the cathedral will be more closely packed with sand than space is with stars.

Don’t Assume

1 Comment

In interacting and communicating with other people we make a lot of assumptions about the other person. Sure, we have to make some assumptions to even begin to communicate (for instance that the other person can understand our language); if we didn’t we would have to start every conversation by asking a complete set of detailed questions – so many we would end up never communicating anything. But making too many, and too deep, assumptions, and not testing those we must make, is highly dangerous. Along with not listening to what the other person actually says, is in my experience the root cause of the majority of misunderstandings.

So I decided to set out those things which it seems to me we assume about the other person or the situation at our peril:

  • Any one person speaks for everyone
  • Anyone is right about anything
  • “Culture” or “society” is the same everywhere and for everybody
  • Someone else’s ethics and morals are the same as yours
  • How young or old or young the person is
  • Someone else is of a given race or nationality
  • What someone else’s religion or spiritual belief system is
  • What someone else’s first language or nationality is
  • What someone else’s politics are
  • What someone else’s personal values are
  • What someone else’s economic class is
  • What someone else’s financial situation is
  • What someone else’s level of education is
  • What someone else’s level of intelligence is
  • What someone else’s experiences or background are
  • What someone else’s life history is
  • What the person’s family or home background is
  • What someone else’s sexuality is or that someone else’s sexual ideals or ethics are the same as yours
  • Someone else has the same body or beauty ideals you do
  • Someone else has the same values, desires, interests, likes and dislikes as you
  • All things have the same effect on all people
  • Anything is universally yucky or universally yummy
  • What someone else’s skills and aptitudes are
  • What you find easy or hard they will also find easy or hard
  • What worked for you will work for anyone else
  • Someone else is better, worse, the same or different to you
  • Any given word means the same thing to everyone
  • One kind of learning works for everyone
  • Your logic is someone else’s logic
  • What they think is the same as you think
  • Someone else’s common sense is the same as your common sense
  • What is right for you is right for anyone else, and vice versa
  • Anything is possible or impossible

Yes we often can (and do) make pretty good guesses at many of these and we base our initial communications on them, but we’d better be prepared to test our guesses and change our position accordingly. I’m sure we’ve all been in situations where we’ve made an assumption about (say) someone’s education only to find we’re totally wrong – haven’t we all come across someone with a doctorate doing a job we wouldn’t expect (driving a taxi or a bus, dealing in second-hand books, selling insurance). Or we’ve spoken to a colleague on the phone and then been surprised on meeting them to find they’re a Sikh, a Muslim or Afro-Caribbean. 

Beware quicksands! … Orator caveo.
