Sense perception and reality

This is such an amazing essay, clear and (for the subject matter) concise, and written in simple no-fuss terminology. I haven't finished it yet, but am really enjoying it, though once the diagrams started I found it a bit offputting as reminded me of school maths and geometry!

Anyway, here's the link

and a quote............."There are three essential points that need to be understood when trying to understand the universe we perceive. The first is that what we see varies with the sensory apparatus used to make the observation. The second is that it is not possible to get past the veil of perception to see things how they are; if there is any particular way that they are. The third is that there is no special or standard or normal means of or conditions of observation that can show us how things really are. If there is any special or single way things are, it is not available to us. One problem with many arguments about our perception of the universe is that they assume we can somehow know how things really are, when this is in fact impossible."

Nothing as lovely as a tree

Nelson Eddy sings "Trees", music by Oscar Rasbach

TREES

 Joyce Kilmer 1914

I think  that I shall never see

A poem lovely as a tree.

 

A tree whose hungry mouth is prest

Against the earth's sweet flowing breast;

 

A tree that looks at God all day,

And lifts her leafy arms to pray;

 

A tree that may in Summer wear

A nest of robins in her hair;

 

Upon whose bosom snow has lain;

Who intimately lives with rain.

 

Poems are made by fools like me,

But only God can make a tree.

Perchance to dream

“Why don't we dream when we are awake?". I would suggest that being 'awake' is when we dream best and continuously. Assuming the world, external to ourselves, exists, then the only access we have to it is through sense data. This stream of nerve impulses, which passes from our sensory receptors to our brain, cannot be said to represent, nor to be analagous to, those events which occur 'out there'. We can only assume that the brain 'fabricates' an image, of external reality, which serves to allow us to interact with it. It is this process of 'fabrication' that I would suggest is no more, or less, than dreaming. The real question is, "Why do we dream when we are asleep?".

Global Noise protests

from today's Guardian, UK

Today am feeling sad looking at the photos of the protesters in Spain and Mexico and Venice, bashing pots and pans against the austerity measures. So clearly and patently unjust and disgusting, that bankers and corporations destroy the economy, not to mention the environment, and the ordinary public have to pick up the bill for getting it back on track, if that is actually what the austerity measures are about at all, seems just as likely that they’re just a means of further squashing down the populace, removing more basic safeguards and increasingly destroying hope and the willpower to stand up for ourselves.

Bang a pot for freedom and justice, it’s heartbreaking, we’re so fragile and easily crushed, and they’re so brutal.

Rise and Shine

 

There’s plenty for everyone here. The technology to transform the world into a garden of delight is here. The wisdom and intelligence to order and maintain harmony and parity for all is here. It’s all here. It’s all within you, dreaming of the opportunity to awaken into reality and replace the sad legacy that has dogged our heels from time out of memory.

Everything is broken

Just look at us, everything is backwards; everything is upside down. Doctors destroy health, lawyers destroy justice, universities destroy knowledge, governments destroy freedom the major media destroys information and religion destroys spirituality.

Songs of Freedom

My last few posts have been song recordings and lyrics (at least for laptop and desktop users – not working yet on Ipads and mobiles – will try to remedy soon!).  After starting off with quotes and then intermingling images that encapsulated what seemed important to me, I realised of course that music is the ultimate form of communication, with its power to move the listener. Anyway then of course a whole stream of songs have come to mind, so far protest songs but I have more I want to put on here that are not so overtly political.

Not sure how long I will continue in this vein for but for now it feels right, so more to follow.

Huge thanks to podcasters and posters and other audio-savvy people who have put these songs online – I’ve used mp3.rapidlibrary.com for all the songs so far, a brilliant free resource.

The Death of Emmett Till

Click play to hear the song

 

Twas down in Mississippi no so long ago,
When a young boy from Chicago town stepped through a Southern door.
This boy's dreadful tragedy I can still remember well,
The color of his skin was black and his name was Emmett Till. 
Some men they dragged him to a barn and there they beat him up.
They said they had a reason, but I can't remember what.
They tortured him and did some evil things too evil to repeat.
There was screaming sounds inside the barn, there was laughing sounds out on the street. 
Then they rolled his body down a gulf amidst a bloody red rain
And they threw him in the waters wide to cease his screaming pain.
The reason that they killed him there, and I'm sure it ain't no lie,
Was just for the fun of killin' him and to watch him slowly die. 
And then to stop the United States of yelling for a trial,
Two brothers they confessed that they had killed poor Emmett Till.
But on the jury there were men who helped the brothers commit this awful crime,
And so this trial was a mockery, but nobody seemed to mind. 
I saw the morning papers but I could not bear to see
The smiling brothers walkin' down the courthouse stairs.
For the jury found them innocent and the brothers they went free,
While Emmett's body floats the foam of a Jim Crow southern sea. 
If you can't speak out against this kind of thing, a crime that's so unjust,
Your eyes are filled with dead men's dirt, your mind is filled with dust.
Your arms and legs they must be in shackles and chains, and your blood it must refuse to flow,
For you let this human race fall down so God-awful low! 

This song is just a reminder to remind your fellow man
That this kind of thing still lives today in that ghost-robed Ku Klux Klan.
But if all of us folks that thinks alike, if we gave all we could give,
We could make this great land of ours a greater place to live.

Strange Fruit

Southern trees bear strange fruit,
Blood on the leaves and blood at the root,
Black bodies swinging in the southern breeze,
Strange fruit hanging from the poplar trees.

Pastoral scene of the gallant south,
The bulging eyes and the twisted mouth,
Scent of magnolias, sweet and fresh,
Then the sudden smell of burning flesh.

Here is the fruit for the crows to pluck,
For the rain to gather, for the wind to suck,
For the sun to rot, for the trees to drop,
Here is a strange and bitter crop.

Abel Meeropol, 1936

The really famous version of this is sung by Billie Holiday and is electrifying.

Still I think this Robert Wyatt version is powerful and different so I have put it on here.

Most people know the story of the song, but for anyone who doesn’t, it was written by Abel Meeropol, a white Jewish high-school teacher from the Bronx, in response to his horror at the racist lynchings in America at that time and in particular after seeing a photograph of a lynching.
