To the Blindsight delight, he moved around every obstacle with ease, Scodelario one point even pressing himself up against the wall to squeeze past a trashcan placed in his way. We can, of course, ask them. The eyes receive light and convert it into information that is then passed into the brain. And precisely where in the brain does consciousness begin and end? There are three theories for the explanation of blindsight. Stream stereoscopic information is attached to the object information passed to the visual cortex.Blindsight Blindsight debunked? Video
Peter Watts, Blindsight - Part 1Well, it happens. As a result, Barry was completely blind, and he walked with a stick. One day, some psychologists placed Barry in a corridor full of obstacles like boxes and chairs.
They took away his walking stick and told him to walk down the corridor. The result of this simple experiment would prove dramatic for our understanding of consciousness.
Barry was able to navigate around the obstacles without tripping over a single one. Barry has blindsight, an extremely rare condition that is as paradoxical as it sounds.
People with blindsight consistently deny awareness of items in front of them, but they are capable of amazing feats, which demonstrate that, in some sense, they must be able to see them.
Blindsight results from damage to an area of the brain called the primary visual cortex. This is one of the areas, as you might have guessed, responsible for vision.
Damage to primary visual cortex can result in blindness — sometimes total, sometimes partial. So how does blindsight work?
The eyes receive light and convert it into information that is then passed into the brain. This information then travels through a series of pathways through the brain to eventually end up at the primary visual cortex.
For people with blindsight, this area is damaged and cannot properly process the information, so the information never makes it to conscious awareness.
But the information is still processed by other areas of the visual system that are intact, enabling people with blindsight to carry out the kind of tasks that we see in the case of Barry and Rick.
Blindsight serves as a particularly striking example of a general phenomenon, which is just how much goes on in the brain below the surface of consciousness.
This applies just as much to people without blindsight as people with it. Studies have shown that naked pictures of attractive people can draw our attention , even when we are completely unaware of them.
Other studies have demonstrated that we can correctly judge the colour of an object without any conscious awareness of it.
Blindsight has generated a lot of controversy. Some philosophers and psychologists have argued that people with blindsight might be conscious of what is in front of them after all , albeit in a vague and hard-to-describe way.
This suggestion presents a difficulty, because ascertaining whether someone is conscious of a particular thing is a complicated and highly delicate task.
We can, of course, ask them. But interpreting what people say about their own experiences can be a thorny task.
Theseus is propelled by an antimatter reactor and captained by an artificial intelligence. It carries a crew of five cutting-edge transhuman hyper-specialists of whom one is a genetically reincarnated vampire and acts as the nominal mission commander.
While the crew is in hibernation en route, the just-arrived second wave of probes commence a compounded radar scan of the subsurface of Burns-Caulfield, but this immediately causes the object to self-destruct.
Theseus is re-routed mid-flight to the new-found destination of the signal: a previously undetected sub-brown dwarf deep in the Oort Cloud , dubbed 'Big Ben'.
The crew wakes from hibernation while the Theseus closes on Big Ben. They discover a giant, concealed object in the vicinity, and assume it to be a vessel of some kind.
As soon as the crew uncloaks the vessel, it immediately hails them over radio and, in a range of languages varying from English to Chinese, identifies itself as 'Rorschach'.
They determine that Rorschach must have learned human languages by eavesdropping on comm-chatter since its arrival, sometime after the Broadcast Age began.
Over the course of a few days many questions and answers are exchanged by both parties. Eventually Susan James, the linguist, determines that 'Rorschach' doesn't really understand what either party is actually saying.
Theseus probes Rorschach and finds it to have hollow sections, some with atmosphere, all filled with levels of radiation that render remote operation of machinery virtually impossible and would kill a human in a matter of hours.
Despite this and over Rorschach's objections the whole crew except the mission commander enters and explores in a series of short forays, using the ship's advanced medical facilities to recover from the damage the radiation inflicts on their bodies.
They discover the presence of highly evasive, fast-moving 9-legged organisms dubbed 'Scramblers', of which they kill one and capture two for study.
The 'Scramblers' appear to have orders of magnitude more brainpower than human beings but use most of it simply to operate their fantastically complex musculature and sensory organs; they are more akin to something like white blood cells in a human body.
They are dependent on the radiation and EM fields of Rorschach for basic biological functions and seem to completely lack consciousness.
The crew explore questions of identity, the nature, utility and interdependence of intelligence and consciousness.
They theorize that humanity could be an unusual offshoot of evolution, wasting bodily and economic resources on the self-aware ego which has little value in terms of Darwinian fitness.
Open warfare breaks out between the humans and the Scramblers and Theseus eventually decides to sacrifice itself and its crew using its antimatter payload to eliminate Rorschach.
One crew member, the protagonist and narrator Siri Keeton, is shot off inside an escape vessel in a decades-long fall back to Earth to relay the crucial information amassed back to humanity.
As he travels back towards the inner Solar System, he hears radio broadcasts which suggest that the vampires have revolted and may be exterminating baseline humanity.
The exploration of consciousness is the central thematic element of Blindsight. Is the interior experience of consciousness necessary, or is externally observed behavior the sole determining characteristic of conscious experience?
Philosopher John Searle 's Chinese room thought experiment is used as a metaphor to illustrate the tension between the notions of consciousness as an interior experience of understanding, as contrasted with consciousness as the emergent result of merely functional non-introspective components.
The alien creatures encountered by the crew of the Theseus themselves lack consciousness. We do not like annoying cousins.
There were three linguistic ambiguities in there. It just ignored them. Different thing entirely. The notion that these aliens could lack consciousness and possess intelligence is linked to the idea that some humans could also have diminished consciousness and remain outwardly functional.
Blindsight supposes that sociopaths might be a manifestation of this same phenomenon, [9] [11] and the demands of corporate environments might be environmental factors causing some part of humanity to evolve toward becoming philosophical zombies.
Blindsight also explores the implications of a transhuman future. Carl Hayes, in his review for Booklist , wrote: "Watts packs in enough tantalizing ideas for a score of novels while spinning new twists on every cutting-edge motif from virtual reality to extraterrestrial biology.
Elizabeth Bear , an award-winning author in the science fiction field, declared:. It's my opinion that Peter Watts's Blindsight is the best hard science fiction novel of the first decade of this millennium — and I say that as someone who remains unconvinced of all the ramifications of its central argument.
Watts is one of the crown princes of science fiction's most difficult subgenre: his work is rigorous, unsentimental, and full of the sort of brilliant little moments of synthesis that make a nerd's brain light up like a pinball machine.
But he's also a poet — a damned fine writer on a sentence level From Wikipedia, the free encyclopedia. For other uses, see Blindsight disambiguation.
