Universal language of genes
The Genetic Code is the language with which DNA talks to the rest of
your body chemistry. The function of a gene is to give the body
instructions for making a particular protein. One gene, one
protein. And the letters in the DNA molecule (A, C, T, G) combine
in 3-letter words, in which each 3-letter word stands for an amino acid.
Cells are equipped with machinery that speaks this language, and reading
3-letter codons from the DNA template,
ribosomes add one
amino acid at a time until a protein is built to spec.
Biochemists since Francis Crick in the 1950s have taken the Genetic
Code to be an arbitrary language. Now it turns out not to be so
arbitrary. There is a natural chemical affinity between each
3-letter codon and the corresponding amino acid. This is a big
hint about how the Genetic Code came to be. It is possible that
the Code was created first, and ribosomes came later, as a refinement.

Squirming
Every practitioner of mindfulness learns that the longer we sit still,
the deeper and more uncomfortable are the truths we are invited to
confront.
Acknowledging the truth about who we are is a process that demands
ruthlessness and tenderness in equal measure.

Invocation to Kali
It is time for the invocation, to atone
For what we fear most and have not dared to face:
Kali, the destroyer, cannot be overthrown;
We must stay, open-eyed, in the terrible place.
Every creation is born out of the dark.
Every birth is bloody. Something gets torn.
Kali is there to do her sovereign work
Or else the living child will be stillborn.
It is time for the invocation:
Kali, be with us.
Violence, destruction, receive our homage.
Help us to bring darkness into the light,
To lift out the pain, the anger,
Where it can be seen for what it is—
The balance-wheel for our vulnerable, aching love.
Put the wild hunger where it belongs,
Within the act of creation,
Crude power that forges a balance
Between hate and love.
Help us to be the always hopeful
Gardeners of the spirit
Who know that without darkness
Nothing comes to birth
As without light
Nothing flowers.
Bear the roots in mind,
You, the dark one, Kali,
Awesome power.
— May Sarton, born this day in 1912

Paradigm and Paradox
Reason and imagination. Theme and improvisation. Structure and chaos.
Sometimes we stay within the lines, at other times, though not often
enough, we bravely step outside the box to fly high or free fall or
float along unencumbered.
We encounter paradigm daily in the norms and expectations, roles and
regulations of religion and society.
Paradigm is clear and convincing and difficult to remove. Paradox, on
the other hand, is contradictory and unbelievable, absurd and often
compelling, impossible but true. It projects the tension of opposites
that are held simultaneously, and is therefore given short shrift by the
logical Western mind. We come up against it everywhere, and more often
than not we dismiss it by saying, that’s just the way it is, or, it’s a
mystery.
— Miriam Therese Winter, from
Paradoxology.
It is time we refuse to accept disempowering models that mimic community,
time to reject outrageous behavior from those in leadership roles.

New Scientist on quantum weirdness
It is tempting, faced with the full-frontal assault of quantum
weirdness, to trot out the notorious quote from Nobel prize-winning
physicist Richard Feynman: “Nobody understands quantum mechanics.”
It does have a ring of truth to it, though. The explanations attempted
here use the most widely accepted framework for thinking about quantum
weirdness, called the Copenhagen
interpretation after the
city in which Niels Bohr and Werner Heisenberg thrashed out its ground
rules in the early 20th century.
With its uncertainty principles and measurement paradoxes, the
Copenhagen interpretation amounts to an admission that, as classical
beasts, we are ill-equipped to see underlying quantum reality. Any
attempt we make to engage with it reduces it to a shallow classical
projection of its full quantum richness.
Lev Vaidman of Tel Aviv University, Israel, like many other physicists,
touts an alternative explanation. “I don’t feel that I don’t understand
quantum mechanics,” he says. But there is a high price to be paid for
that understanding - admitting the existence of parallel
universes.
In this picture, wave functions do not “collapse” to classical certainty
every time you measure them; reality merely splits into as many parallel
worlds as there are measurement possibilities. One of these carries you
and the reality you live in away with it. “if you don’t admit
many-worlds, there is no way to have a coherent picture,”
says Vaidman.
Or, in the words of Feynman again, whether it is the Copenhagen
interpretation or many-worlds you accept, “the ‘paradox’ is only a
conflict between reality and your feeling of what reality ought to be”.
Read more: Seven
wonders of the quantum world
You’ll forgive me if I don’t make a quantum leap to Vaidman’s
Many
Worlds perspective. Which world do I live in? Does it
matter if I am the one making the measurement, or if it is someone else?
Is a measurement made whenever a macroscopic particle is affected, or
only a conscious mind perceives something? I remain mystified.

Beyond all Shores and Seas
LIES yet a well of wonder
All shores and seas beyond,
Where shines that dimness under,
More deep than in a dream,
Full many a diamond
With elfin gleam,
Glows up the glimmering water
Full many a ruby’s fire:
If ever an earth-born daughter
Their wizard light behold,
She may no more desire
Our gems and gold.
|
Nay, some in sooth, who only
A dream thereon did gaze,
Thenceforth fare wandering lonely,
And seek with sorrow vain
The glory of such rays
To find again.
Oft, oft, high-heavenward turning
The quivering stars have conned,
Or watched the wide west burning
Nor shall their hearts appease,
Whose hope lies hid beyond
All shores and seas.

Five Hindrances + One
In the Theravada Buddhist tradition, there are
five obstacles
to the ongoing practice of mindfulness:
- Clinging (I want)
- Aversion (Get that away from me)
- Agitation (’nuf of this sittin’ around)
- Torpor (yawn)
- Cynicism (yeah, yeah)
... to which Bob Chapra adds
- Doctrine (especially the making of numbered lists)
Just eliminate these tendencies from our minds, and we’ll be fine.
I guarantee it.

How to teach
The lowest form of teaching is to repeat what has been taught to you.
Better is to share your experience with your students.
Best is to create a space in which students may have experiences of
their own, process and share their responses with you and with each other.

Birthday indulgence
I have come to realize that the way my emotional life has
something in common with the way
Charles Ponzi
managed money. That is, I am constantly engaged in
planning for the future, promising myself a success or a joy, and (what
is ironic) delighting for real in the anticipation of a reward which is a
mirage.
On days that I work hard, exercise for health, create something,
learn something, reach for a political goal, I am genuinely happy.
On days that I seek to reap my reward (Happy Birthday!) I feel
shortchanged, and consumed by emptiness. ‘Is this all there is?’
When I see through this it can be a Cosmic Tragedy, but equally well it
may seem a Cosmic Joke.

Genetic basis for morality
‘With the help of well designed experiments, you can see glimmers of
moral thought, moral judgment and moral feeling even in the first year

David Derbyshire article in Mail Online UK
Once we realize that aspects of morality are in our genes, hard-wired
into our brains, does that give us more faith or less faith in morality?
On the one hand, it suggests that morality is more than a cultural
construct, with validity limited to a given cultural context. On
the other hand, it puts morality in the same class with fear,
aggression, hunger, greed and a host of other emotional responses that
have been programmed by evolution into our brains.

The only refuge
Our life’s work as humans: the transition from seeking comfort in
predictability and stasis to taking comfort in mystery,
unpredictability, and faith in a larger benevolence. For
followers, this transition is usually made through a social group, and
the faith is in religious doctrines received. But for scientific
types, there exists another path to this same place: it consists in
pursuing science to its endpoint, and appreciating the oceans of mystery
that border the scientific islands of understanding.

Breathing Exercise: A How-To Poem
For Gil Fronsdal,
and in memory of Mark O'Brien (1949-1999)
The distance between the brightness
at the top of the spine
and the darkness below it
is not far
but when you shrink your mind
it is enormous
the whole length
of human history
can be fit inside it
One way to reduce it a little
is with practice and preparation
(the latter takes minutes each morning
the former has taken me years)
to gather the sensations in our belly
into our in-breath
(do this slowly and with enjoyment
the darkness deep inside us
should be like the jungle in Thailand
where we may acknowledge the presence
of unseen pythons and kraits
but our actual sensations
as we search the deep canopy
for crimson sunbirds
are of lazy butterflies
and flowering lianas)
and then by a skilled relaxing
of both muscle and nerve
guide our breathing
slowly up the back of our spine
so that it breaks over the top
like a wave breaking over a quiet beach
to drench the scattered thoughts
spread out to no purpose
and then draw them slowly back down
in the descent of the out-breath
to the dark easy rhythm
of the untiring diaphragm
where the in-breath began
Relax the spaces in between
each vertebra
let each space slightly expand
until in each out-breath
you can exhale metta (loving kindness)
commingling the cool light
and warm darkness
to those whom you usually consider
enemies and friends
— Peter Dale Scott

From an Inaugural NYTimes Philosophy Blog
Socrates tells the story of Thales, who was by some accounts the first
philosopher. He was looking so intently at the stars that he fell into a
well...What is a philosopher, then? a laughing stock, an absent-minded
buffoon, the butt of countless jokes...
As Wittgenstein says, “This is how philosophers should salute each
other: ‘Take your time.’”...
Socrates says that those in the constant press of business, like
lawyers, policy-makers, mortgage brokers and hedge fund managers, become
“bent and stunted” and they are compelled “to do crooked things.” The
pettifogger is undoubtedly successful, wealthy and extraordinarily
honey-tongued, but, Socrates adds, “small in his soul and shrewd and a
shyster.” The philosopher, by contrast, is free by virtue of his or her
otherworldliness, by their capacity to fall into wells and appear silly
.... Because of their laughable otherworldliness and lack of respect for
social convention, rank and privilege, philosophers refuse to honor the
old gods and this makes them politically suspicious, even dangerous.

Enceladus
Enceladus is a minor moon of Saturn, given up by astronomers as a
boring hunk of rock until recent photos returned by the
Cassini spacecraft told a curious story.
There are geysers spewing steam many miles and into space from Enceladus’s south
pole. The earth has vulcanism from a hot, iron core. But
Enceladus is much smaller than the earth, and its core should have
cooled off long ago. What’s going on? The best guess is a two-part
explanation:
- First, ‘boiling hot’ doesn’t mean the same thing on such a small
planet. Because the atmosphere is so thin, water can boil at
temperatures that you and I might not call hot. In fact, the
high temperature found by satellites was 116 degrees C below zero -
still hot enough to boil water in the near-vacuum of space.
- But even this is hotter than the planet ought to be, since it is
so far from the sun and it is white, so it absorbs very little
sunlight. Our best theory about the the energy in the interior
is that it comes from sloshing around of molten rock in the interior
from powerful tidal forces. (Tidal forces come from the fact
that one side of the moon is closer to the sun, and is pulled harder
by the sun’s gravity, while the other side is closer to Saturn, and
so is pulled harder by Saturn. A few days later, the moon
moves so that the sun and Saturn are now on the same side
of it, and so molten rock in the interior is drawn back and forth
repeatedly.)
Maybe there’s an ocean of liquid water under Enceladus’s surface.
Maybe there’s life in that ocean.

faith in God into work for political change. Her family founded
the Barclay Bank of England, but she worked to house the homeless.
She used her freedom to work on behalf of prisoners, advocating
successfully for reform.

there is a God. I have been devotional and my mind has been led away
from the follies that it is mostly wrapped up in.

The Silken Tent
She is as in a field a silken tent
At midday when a sunny summer breeze
Has dried the dew and all its ropes relent,
So that in guys it gently sways at ease,
And its supporting central cedar pole,
That is its pinnacle to heavenward
And signifies the sureness of the soul,
Seems to owe naught to any single cord,
But strictly held by none, is loosely bound,
By countless silken ties of love and thought
To everything on earth the compass round
And only by one’s going slightly taut
In the capriciousness of summer air
Is of the slightest bondage made aware.

Principia Mathematica,
the masterpiece of Bertrand Russel’s youth, was published 100 years
ago today. In it, he and Alfred Whitehead sought to put
mathematics on a firm logical footing, by proving that every well-formed
statement that could be made from a minimal set of math symbols was
either true or false. Math may be subtle, but at least
mathematicians can be sure that they’re not on a fool’s errand, trying
to devise a proof when, in fact, none is possible. Russell and
Whitehead published their book, despite recognizing that there was a
small loophole left to be plugged in
This was a bulwark of
Logical
Positivism, helping to distinguish a philosophy that eschews
abstraction, and posits that the physical universe is all we have, and
all that we have any business talking to each other about.
No one imagined that the thesis could be false, except Kurt Godel, a
young German mathematician who worked hard not to prove but to
disprove it. In 1926, he demonstrated that every
mathematical system has an infinite number of statements that seem to
make perfect sense, but they are are ‘in limbo’, forever neither true
nor false. There is no proof and no disproof that can resolve
this.
Other problems with the Positivist program soon surfaced. The Quantum Theory at the basis of physical descriptions of reality describes
a world quite alien the Logical Positivists. For example,
individual particles have no separate existence, but can only be
described (as in a laser) as part of an indivisible multi-particle
state. Today, Logical Positivism is alive and well, in that most
Westerners who think of themselves as enlightened and above superstition
treat the world as if it were rational and objective. The fact
that the foundation of their faith has failed the test of empiricism
doesn’t seem to bother them. To me, the point is that there is a
portal from science to mysticism. |

All the world
The fiction of dignity helps to define humanity and the status of
humanity helps to define human rights. There is thus a real sense in
which an affront to our dignity strikes at our rights. Yet when,
outraged at such affront, we stand on our rights and demand redress, we
would do well to remember how insubstantial the dignity is on which
those rights are based. Forgetting where our dignity comes from, we may
fall into a posture as comical as that of the irate censor.
Life, says Erasmus’s Folly, is theater: we each have lines to say and a
part to play. One kind of actor, recognizing that he is in a play, will
go on playing nevertheless; another kind of actor, shocked to find he is
participating in an illusion, will try to step off the stage and out of
the play. The second actor is mistaken. For there is nothing outside the
theater, no alternative life one can join instead. The show is, so to
speak, the only show in town. All one can do is to go playing one’s
part, though perhaps with a new awareness, a comic awareness.
We thus arrive at a pair of Erasmian paradoxes. A dignity worthy of
respect is a dignity without dignity (which is quite different from
unconscious or unaffected dignity); an innocence worthy of respect is an
innocence without innocence. As for respect itself, it is tempting to
suggest that it is a superfluous concept, though for the workings of the
theater of life it may turn out to be indispensable. True respect is a
variety of love and may be subsumed under love; to respect someone
means, inter alia, to forgive that person an innocence that,
outside the theater, would be false, a dignity that would be risible.

‘Being a scientist is a special privilege: for
it brings the opportunity to be creative, the passionate quest for
answers to nature's most precious secrets, and the warm friendships of
many valued colleagues. Collaborations extend far beyond the scientific
achievements, no matter how great the accomplishments might be, the rich
friendships which have no national borders are treasured even more.’
Stanley Prusiner, born this day in 1942, discovered that an
infectious agent could exist without any DNA or RNA. It is simply
a misfolded version of one of the body’s essential proteins. Is it
just chance misfortune that copies of this protein twisted in a
particular way have the ability to transform other, properly folded
proteins into the wrong shape? The Creutzfeldt-Jakob prion
reproduces selfishly as though it were an evolved parasite. But
evolution works on DNA, not on proteins (which are always derived from
DNA, and never vice versa.) This mystery remains
unresolved.
‘Because our results were so novel, my
colleagues and I had great difficulty convincing other scientists of the
veracity of our findings and communicating to lay people the importance
of work that seemed so esoteric! As more and more compelling data
accumulated, many scientists became convinced.’
Prusiner is being modest. He began his researches 20 years
after the first prion hypothesis, and though his results seemed
absolutely conclusive, it required another 15 years for the medical
community to accept his results.

‘This is our purpose: to make as meaningful

way that we may be proud of ourselves; to act in such a way that some
part of us lives on.’
Oswald
Spengler, born this day in 1880, read broadly about distant cultures
and ancient times, saw clearly the great heights and political dangers
of his time and of ours. I am particularly struck by his
appreciation of the ease with which a free press can be made subservient
to the larger-than-life lies of a political regime:
‘The press today is an army with carefully
organized weapons, the journalists its officers, the readers its
soldiers. But, as in every army, the soldier obeys blindly, and the war
aims and operating plans change without his knowledge. The reader
neither knows nor is supposed to know the purposes for which he is used
and the role he is to play. There is no more appalling caricature of
freedom of thought. Formerly no one was allowed to think freely; now it
is permitted, but no one is capable of it any more. Now people want to
think only what they are supposed to want to think, and this they
consider freedom.’

Faith in what?
It matters little in what object we invest our faith. It is faith
itself that releases us from fear, liberating our self-expression, our experience
and our development.
— Josh Mitteldorf
That said, I would not advocate faith in
violence, in social theories that privilege some groups to subjugate
others, or in political or religious demagogues. It is not the faith that is at
fault here, but rather the consequences of blind obedience to leaders or
ideologies that gain their power by promoting conflict.
We who come from a rational, enlightened tradition
may find that the very arbitrariness of the object of faith becomes a
hindrance to belief. Can we raise faith through an act of will?
I submit that we can, and that it is stubbornness and hubris to deny ourselves the benefit
of faith as we stand on ceremony as exclusively rational beings.
I resolve this conflict in my own life as I consciously evoke and reinforce my faith, beginning at the point
where scientific understanding leaves off.

there is no pleasure in it for them, when they do it by force. Besides,
there are a thousand ways of tormenting them. Never fear, they'll soon
tire of the game; there's no satisfaction for a man, unless the woman
shares it.
