Death Note vs. The World, the Flesh, and the Devil; An Enquiry into the Three Enemies of the Rational Soul

In the anime and manga series Death Note, the pseudo-protagonist and villain named Kira wanted to get rid of all the World's evil. He thought he found the solution in the Death Note; a notebook owned by a Shimigami (Death God) which has the ability to take peoples lives simply by writing their names in it. Kira endevours in punishing the whicked by writing their names in the Death Note. More ambitious was his declaration to the world that he "Kira" will be the world's ne law and God. The series continues with "L" the world's greatest detective taking on Kira's challenge and cascades into the equally mathced battles of Kira and L. The series probes deep into the moral issues confronting the world today and provokes a sense of justice for what is morally right and just.
Desmond Bernal has another story to tell though. In "The World, the Flesh and the Devil: An Enquiry into the Future of the Three Enemies of the Rational Soul", Bernal saw science as our best tool for defeating the three enemies. The World means floods and famines and climate changes. The Flesh means diseases and senile infirmities. The Devil means the dark irrational passions that lead otherwise rational beings into strife and destruction.

The Rise of AI

Consciousness is part of the natural world. It depends, we believe, only on mathematics and logic and on the imperfectly known laws of physics, chemistry, and biology; it means there's no reason why consciousness can't be reproduced in a machine—in theory, anyway.
In humans and animals, we know that the specific content of any conscious experience—the deep blue of an alpine sky, say, or the fragrance of jasmine redolent in the night air—is furnished by parts of the cerebral cortex, the outer layer of gray matter associated with thought, action, and other higher brain functions. If a sector of the cortex is destroyed by stroke or some other calamity, the person will no longer be conscious of whatever aspect of the world that part of the brain represents. For instance, a person whose visual cortex is partially damaged may be unable to recognize faces, even though he can still see eyes, mouths, ears, and other discrete facial features. Consciousness can be lost entirely if injuries permanently damage most of the cerebral cortex, as seen in patients like Terri Schiavo, who suffered from persistent vegetative state. Lesions of the cortical white matter, containing the fibers through which parts of the brain communicate, also cause unconsciousness. And small lesions deep within the brain along the midline of the thalamus and the midbrain can inactivate the cerebral cortex and indirectly lead to a coma—and a lack of consciousness.
To be conscious also requires the cortex and thalamus—the corticothalamic system—to be constantly suffused in a bath of substances known as neuromodulators, which aid or inhibit the transmission of nerve impulses. Finally, whatever the mechanisms necessary for consciousness, we know they must exist in both cortical hemispheres independently.
Much of what goes on in the brain has nothing to do with being conscious, however. Widespread damage to the cerebellum, the small structure at the base of the brain, has no effect on consciousness, despite the fact that more neurons reside there than in any other part of the brain. Neural activity obviously plays some essential role in consciousness but in itself is not enough to sustain a conscious state. We know that at the beginning of a deep sleep, consciousness fades, even though the neurons in the corticothalamic system continue to fire at a level of activity similar to that of quiet wakefulness.
Data from clinical studies and from basic research laboratories, made possible by the use of sophisticated instruments that detect and record neuronal activity, have given us a complex if still rudimentary understanding of the myriad processes that give rise to consciousness. We are still a very long way from being able to use this knowledge to build a conscious machine. Yet we can already take the first step in that long journey: we can list some aspects of consciousness that are not strictly necessary for building such an artifact.
Remarkably, consciousness does not seem to require many of the things we associate most deeply with being human: emotions, memory, self-reflection, language, sensing the world, and acting in it. Let's start with sensory input and motor output: being conscious requires neither. We humans are generally aware of what goes on around us and occasionally of what goes on within our own bodies. It's only natural to infer that consciousness is linked to our interaction with the world and with ourselves.
Yet when we dream, for instance, we are virtually disconnected from the environment—we acknowledge almost nothing of what happens around us, and our muscles are largely paralyzed. Nevertheless, we are conscious, sometimes vividly and grippingly so. This mental activity is reflected in electrical recordings of the dreaming brain showing that the corticothalamic system, intimately involved with sensory perception, continues to function more or less as it does in wakefulness.
Neurological evidence points to the same conclusion. People who have lost their eyesight can both imagine and dream in images, provided they had sight earlier in their lives. Patients with locked-in syndrome, which renders them almost completely paralyzed, are just as conscious as healthy subjects. Following a debilitating stroke, the French editor Jean-Dominique Bauby dictated his memoir, The Diving Bell and the Butterfly, by blinking his left eye. Stephen Hawking is a world-renowned physicist, best-selling author, and occasional guest star on “The Simpsons,” despite being immobilized from a degenerative neurological disorder.
So although being conscious depends on brain activity, it does not require any interaction with the environment. Whether the development of consciousness requires such interactions in early childhood, though, is a different matter.
How about emotions? Does a conscious being need to feel and display them? No: being conscious does not require emotion. People who've suffered damage to the frontal area of the brain, for instance, may exhibit a flat, emotionless affect; they are as dispassionate about their own predicament as they are about the problems of people around them. But even though their behavior is impaired and their judgment may be unsound, they still experience the sights and sounds of the world much the way normal people do.
Primal emotions like anger, fear, surprise, and joy are useful and perhaps even essential for the survival of a conscious organism. Likewise, a conscious machine might rely on emotions to make choices and deal with the complexities of the world. But it could be just a cold, calculating engine—and yet still be conscious.
Psychologists argue that consciousness requires selective attention—that is, the ability to focus on a given object, thought, or activity. Some have even argued that consciousness is selective attention. After all, when you pay attention to something, you become conscious of that thing and its properties; when your attention shifts, the object fades from consciousness.
Nevertheless, recent evidence favors the idea that a person can consciously perceive an event or object without paying attention to it. When you're focused on a riveting movie, your surroundings aren't reduced to a tunnel. You may not hear the phone ringing or your spouse calling your name, but you remain aware of certain aspects of the world around you. And here's a surprise: the converse is also true. People can attend to events or objects—that is, their brains can preferentially process them—without consciously perceiving them. This fact suggests that being conscious does not require attention.
One experiment that supported this conclusion found that, as strange as it sounds, people could pay attention to an object that they never “saw.” Test subjects were shown static images of male and female nudes in one eye and rapidly flashing colored squares in the other eye. The flashing color rendered the nudes invisible—the subjects couldn't even say where the nudes were in the image. Yet the psychologists showed that subjects nevertheless registered the unseen image if it was of the opposite sex.
As it turns out, though, being conscious does not require self-reflection. When we become absorbed in some intense perceptual task—such as playing a fast-paced video game, swerving on a motorcycle through moving traffic, or running along a mountain trail—we are vividly conscious of the external world, without any need for reflection or introspection.
Neuroimaging studies suggest that we can be vividly conscious even when the front of the cerebral cortex, involved in judgment and self-representation, is relatively inactive. Patients with widespread injury to the front of the brain demonstrate serious deficits in their cognitive, executive, emotional, and planning abilities. But they appear to have nearly intact perceptual abilities.
Finally, being conscious does not require language. We humans affirm our consciousness through speech, describing and discussing our experiences with one another. So it's natural to think that speech and consciousness are inextricably linked. They're not. There are many patients who lose the ability to understand or use words and yet remain conscious. And infants, monkeys, dogs, and mice cannot speak, but they are conscious and can report their experiences in other ways.
So what about a machine? We're going to assume that a machine does not require anything to be conscious that a naturally evolved organism—you or me, for example—doesn't require. If that's the case, then, to be conscious a machine does not need to engage with its environment, nor does it need long-term memory or working memory; it does not require attention, self-reflection, language, or emotion. Those things may help the machine survive in the real world. But to simply have subjective experience—being pleased at the sight of wispy white clouds scurrying across a perfectly blue sky—those traits are probably not necessary.
To be conscious, you need to be a single integrated entity with a large repertoire of states. Let's take this one step further: your level of consciousness has to do with how much integrated information you can generate. That's why you have a higher level of consciousness than a tree frog or a supercomputer. To make a machine conscious, two complementary strategies come to mind: either copying the mammalian brain or evolving a machine. Research groups worldwide are already pursuing both strategies, though not necessarily with the explicit goal of creating machine consciousness.Can Machines become Conscious?

Strange Bounces in the Human Response to Change

(image: Lord of the Rings)
"I am an optimist because I have a hunch Mark Twain was right when he portrayed Huckleberry Finn as an archetype of human nature. In the pivotal moment of his novel, Huckleberry Finn considers struggling no longer against the great challenges arrayed against him. He thinks about how society would shame him if it would get all around that Huck Finn helped a nigger to get his freedom." Joel Garreau
Reflecting on what Joel said, the world of literature does show these strange bounces. In "Casablanca," Rick is ensconced in a cozy world of thieves, swindlers, gamblers, drunks, parasites, refugees, soldiers of fortune, genially corrupt French police and terrifying Nazis. Rick's cynicism is his pride; he sticks his neck out for nobody. His only interest is in seeing his CafĂ© AmĂ©ricain flourish. And then, of course, of all the gin joints in all the towns in all the world, Ilsa walks into his. The rest of the film concerns him betraying his own cauterized heart in service of a higher purpose. As Rick says, "It's still a story without an ending." The most phenomenally successful film series of the recent era – the "Star Wars," "Harry Potter," "Matrix" and "Lord of the Rings" movies – are all driven by a faith in human cussedness, from Han Solo's grudging heroism to little people with furry feet vanquishing the combined forces of Darkness.
This assessment of our species displays a faith that even in the face of unprecedented threats, the ragged human convoy of divergent perceptions, piqued honor, posturing, insecurity and humor will wend its way to glory. It's never too late to change. The ideal is just around the corner.

In my Craft ans Sullen Art (Dylan Thomas) vs. Installation Art (Olafur Eliason)

(One of Olafur Eliason's Installation Art Work)
| In my craft or sullen art Exercised in the still night When only the moon rages And the lovers lie abed With all their griefs in their arms I labour by singing light Not for ambition or bread Or the strut and trade of charms On the ivory stages But for the common wages Of their most secret heart. Not for the proud man apart From the raging moon I write On these spindrift pages Nor for the towering dead With their nightingales and psalms But for the lovers, their arms Round the griefs of the ages, Who pay no praise or wages Nor heed my craft or art Dylan Thomas |
Thanatopsis (William Cullen Bryant)
To him who in the love of Nature holds
Communion with her visible forms, she speaks
A various language; for his gayer hours
She has a voice of gladness, and a smile
And eloquence of beauty, and she glides
Into his darker musings, with a mild
And healing sympathy, that steals away
Their sharpness, ere he is aware. When thoughts
Of the last bitter hour come like a blight
Over thy spirit, and sad images
Of the stern agony, and shroud, and pall,
And breathless darkness, and the narrow house,
Make thee to shudder, and grow sick at heart;--
Go forth, under the open sky, and list
To Nature's teachings, while from all around--
Earth and her waters, and the depths of air--
Comes a still voice--Yet a few days, and thee
The all-beholding sun shall see no more
In all his course; nor yet in the cold ground,
Where thy pale form was laid, with many tears,
Nor in the embrace of ocean, shall exist
Thy image. Earth, that nourished thee, shall claim
Thy growth, to be resolved to earth again,
And, lost each human trace, surrendering up
Thine individual being, shalt thou go
To mix for ever with the elements,
To be a brother to the insensible rock
And to the sluggish clod, which the rude swain
Turns with his share, and treads upon. The oak
Shall send his roots abroad, and pierce thy mould.
Yet not to thine eternal resting-place
Shalt thou retire alone, nor couldst thou wish
Couch more magnificient. Thou shalt lie down
With patriarchs of the infant world--with kings,
The powerful of the earth--the wise, the good
Fair forms, and hoary seers of ages past,
All in one mighty sepulchre. The hills
Rock-ribbed and ancient as the sun,--the vales
Stretching in pensive quietness between;
The venerable woods--rivers that move
In majesty, and the complaining brooks
That make the meadow green; and, poured round all,
Old Ocean's gray and melancholy waste,--
Are but the solemn decorations all
Of the great tomb of man. The golden sun,
The planets, all the infinite host of heaven,
Are shining on the sad abodes of death,
Through the still lapse of ages. All that tread
The globe are but a handful to the tribes
That slumber in its bosom.--Take the wings
Of morning, pierce the Barcan wilderness,
Or lose thyself in the continuous woods
Where rolls the Oregon, and hears no sound,
Save his own dashings--yet the dead are there:
And millions in those solitudes, since first
The flight of years began, have laid them down
In their last sleep--the dead reign there alone.
So shalt thou rest, and what if thou withdraw
In silence from the living, and no friend
Take note of thy departure? All that breathe
Will share thy destiny. The gay will laugh
When thou art gone, the solemn brood of care
Plod on, and each one as before will chase
His favorite phantom; yet all these shall leave
Their mirth and their employments, and shall come
And make their bed with thee. As the long train
Of ages glide away, the sons of men,
The youth in life's green spring, and he who goes
In the full strength of years, matron and maid,
The speechless babe, and the gray-headed man--
Shall one by one be gathered to thy side
By those, who in their turn shall follow them.
So live, and when thy summons comes to join
The innumerable caravan, which moves
To that mysterious realm, where each shall take
His chamber in the silent halls of death,
Thou go not, like a quarry-slave at night,
Scourged to his dungeon, but, sustained and soothed
By an unfaltering trust, approach thy grave,
Like one who wraps the drapery of his couch
About him, and lies down to pleasant dreams.

Science vs. Religion (A Compromise)
Dawkins, Dennet, Harris, Hitchens and other scientists think of religion as a collective delusion, or an idiotic superstition. Yet their turns backfire because it shows how inflexible and intolerant they are. The power of religion resides in so many forms. One of them is hope. Life is tough, people suffer, and religion offers something for people as a means of escape, inner peace, and acceptance. People, love, die, and fight for what they believe in.
On the other hand, the crystal clear and irresistably compelling world of science provides a vehicle for understanding how the world works and how life itself works in its myriad forms. The more we understand life and the universe, the more we realize how rare it is, how precious it is. There maybe life elsewhere and they maybe more colorful than we can ever imagine.
Both science and religion teaches us the virtue of humility. Dawkins and other Scientists should be the first people to know that both in their respect for life and intellectual honesty. Religion should not provide a vehicle for extremism and the extermination of plausible scientific findings. Both love and respect for the beauty and wonders of this planet are theirs .Both should live harmoniously in this precious jewel that we so value. If both camps can work together, the possibilities that both camps can achieve are endless.
The Human Epigenome Project

We're embarking on a kind of map making that will usher in new ways of understanding ourselves- a map that can explain why identical twins are not truly identical, so that one succumbs to schizophrenia while the other remains cognitively inact; why what your mom ate can save or sabotage your health (as well as your children); and how are genetic fates can be tuned by such universals as love or vitamins.
The Human Epigenome Project (HEP) aims to identify, catalogue and interpret genome-wide DNA methylation patterns of all human genes in all major tissues. Methylation is the only flexible genomic parameter that can change genome function under exogenous influence. Mapping 25,000 genes and the three billion pairs of bases in our DNA. Hence it constitutes the main and so far missing link between genetics, disease and the environment that is widely thought to play a decisive role in the aetiology of virtually all human pathologies. Methylation occurs naturally on cytosine bases at CpG sequences and is involved in controlling the correct expression of genes. Differentially methylated cytosines give rise to distinct patterns specific for tissue type and disease state. Such methylation variable positions (MVPs) are common epigenetic markers. Like single nucleotide polymorphisms (SNPs), they promise to significantly advance our ability to understand and diagnose human disease.

The Map (Elizabeth Bishop) vs. The Human Epigenome Project (HEP)

"We're embarking on a kind of map making that will usher in new ways of understanding ourselves.. The double helix lies in the epigenome like land lies in water. The epigenome is a flute playing a tune that charms the snake-coiled snake that is the code of life- and the snake spirals upwards in response. A long bundle of biochemical markers all along the genome, the epigenome responds to environmental signals and then switches genes off or on, upregulates of downregulates their activity. And in that change lies a great part of our destiny."
| Land lies in water; it is shadowed green. Shadows, or are they shallows, at its edges showing the line of long sea-weeded ledges where weeds hang to the simple blue from green. Or does the land lean down to lift the sea from under, drawing it unperturbed around itself? Along the fine tan sandy shelf is the land tugging at the sea from under? The shadow of Newfoundland lies flat and still. Labrador's yellow, where the moony Eskimo has oiled it. We can stroke these lovely bays, under a glass as if they were expected to blossom, or as if to provide a clean cage for invisible fish. The names of seashore towns run out to sea, the names of cities cross the neighboring mountains - the printer here experiencing the same excitement as when emotion too far exceeds its cause. These peninsulas take the water between thumb and finger like women feeling for the smoothness of yard-goods. Mapped waters are more quiet than the land is, lending the land their waves' own conformation: and Norway's hare runs south in agitation, profiles investigate the sea, where land is. Are they assigned, or can the countries pick their colors? -What suits the character or the native waters best. Topography displays no favorites; North's as near as West. More delicate than the historians' are the map-makers' colors Elizabeth Bishop |

Why I Am a Liberal (Robert Browning)
All that I am now, all I hope to be,--
Whence comes it save from fortune setting free
Body and soul the purpose to pursue,
God traced for both? If fetters, not a few,
Of prejudice, convention, fall from me,
These shall I bid men--each in his degree
Also God-guided--bear, and gayly, too?
But little do or can the best of us:
That little is achieved through Liberty.
Who, then, dares hold, emancipated thus,
His fellow shall continue bound? Not I,
Who live, love, labour freely, nor discuss
A brother's right to freedom. That is "Why."
Adequacy (Elizabeth Barrett Browning)
Beloved England, doth the earth appear
Quite good enough for men to overbear
The will of God in, with rebellious wills !
We cannot say the morning-sun fulfils
Ingloriously its course, nor that the clear
Strong stars without significance insphere
Our habitation: we, meantime, our ills
Heap up against this good and lift a cry
Against this work-day world, this ill-spread feast,
As if ourselves were better certainly
Than what we come to. Maker and High Priest,
I ask thee not my joys to multiply,--
Only to make me worthier of the least.
Milton: The Sky is an Immortal Tent Built by the Sons of Los (William Blake)
The sky is an immortal tent built by the Sons of Los:
And every space that a man views around his dwelling-place
Standing on his own roof or in his garden on a mount
Of twenty-five cubits in height, such space is his universe:
And on its verge the sun rises and sets, the clouds bow
To meet the flat earth and the sea in such an order'd space:
The starry heavens reach no further, but here bend and set
On all sides, and the two Poles turn on their valves of gold:
And if he moves his dwelling-place, his heavens also move
Where'er he goes, and all his neighbourhood bewail his loss.
Such are the spaces called Earth and such its dimension.
As to that false appearance which appears to the reasoner
As of a globe rolling through voidness, it is a delusion of Ulro.
The microscope knows not of this nor the telescope: they alter
The ratio of the spectator's organs, but leave objects untouch'd.
For every space larger than a red globule of Man's blood
Is visionary, and is created by the Hammer of Los;
And every space smaller than a globule of Man's blood opens
Into Eternity of which this vegetable Earth is but a shadow.
The red globule is the unwearied sun by Los created

Beowulf

Then the Scylding warrior, savage and grim,
Seized the ring-hilt and swung the sword,
Struck with fury, despairing of life,
Thrust at the throat, broke through the bone-rings;
The stout blade stabbed through her fated flesh.
She sank in death; the sword was bloody;
The hero joyed in the work of his hand.
The gleaming radiance shimmered and shone
As the candle of heaven shines clear from the sky.
Wrathful and resolute Hygelac's thane
Surveyed the span of the spacious hall;
Grimly gripping the hilted sword
With upraised weapon he turned to the wall.
The blade had failed not the battle-prince...
Dover Beach (Arnold Matthew)
The tide is full, the moon lies fair
Upon the straits;--on the French coast the light
Gleams and is gone; the cliffs of England stand,
Glimmering and vast, out in the tranquil bay.
Come to the window, sweet is the night-air!
Only, from the long line of spray
Where the sea meets the moon-blanch'd land,
Listen! you hear the grating roar
Of pebbles which the waves draw back, and fling,
At their return, up the high strand,
Begin, and cease, and then again begin,
With tremulous cadence slow, and bring
The eternal note of sadness in.
Sophocles long ago
Heard it on the {AE}gean, and it brought
Into his mind the turbid ebb and flow
Of human misery; we
Find also in the sound a thought,
Hearing it by this distant northern sea.
The Sea of Faith
Was once, too, at the full, and round earth's shore
Lay like the folds of a bright girdle furl'd.
But now I only hear
Its melancholy, long, withdrawing roar,
Retreating, to the breath
Of the night-wind, down the vast edges drear
And naked shingles of the world.
Ah, love, let us be true
To one another! for the world, which seems
To lie before us like a land of dreams,
So various, so beautiful, so new,
Hath really neither joy, nor love, nor light,
Nor certitude, nor peace, nor help for pain;
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night.
Ovid

The Old Masters: how well they understood
While someone else is eating or opening a window or just walking dully along ...
In Brueghel's Icarus, for instance: how everything turns away
Quite leisurely from the disaster; the ploughman may
Have heard the splash, the forsaken cry,
But for him it was not an important failure. The sun shone
As it had to on the white legs disappearing into the green
Water; and the expensive delicate ship that must have seen
Something amazing, a boy falling out of the sky,
Had somewhere to get to and sailed calmly on.
