Princeton neuroscientist Michael Graziano has write a fascinating longread on the “ grueling scientific and philosophical job ” posed by consciousness , and a new theory that could help slit through the Gordion knot of neurons from which it springs . It ’s posted for your viewing pleasure over at Aeon Magazine , and definitely deserving checking out .
Graziano begin :
Scientific negotiation can get a little dry , so I seek to mix it up . I take out my giant hairy orangutan puppet , do some ventriloquy and quickly become entangled in an argumentation . I ’ll be explaining my hypothesis about how the brain — a biologic machine — generates consciousness . Kevin , the orangutan , begin heckling me . ‘ Yeah , well , I do n’t have a brainiac . But I ’m still conscious . What does that do to your theory ? ’
Kevin is the stark unveiling . Intellectually , nobody is fooled : we all know that there ’s nothing inwardly . But everyone in the consultation experiences an phantasy of sensation emanating from his hirsute head . The force is automatic : being social animals , we project awareness onto the marionette . Indeed , part of the fun of ventriloquy is feel the phantasy while eff , on an intellectual level , that it is n’t real .
Many thinkers have draw near cognisance from a first - person vantage item , the form of philosophical position according to which other people ’s mind seem essentially unknowable . And yet , as Kevin show , we spend a lot of genial energy attributing cognisance to other things . We ca n’t help it , and the fact that we ca n’t help it ought to tell us something about what consciousness is and what it might be used for . If we evolved to recognise it in others – and to erroneously attribute it to puppet , grapheme in stories , and cartoons on a screen — then , despite appearances , it really ca n’t be seal up within the seclusion of our own heads .
Lately , the trouble of consciousness has begun to catch on in neuroscience . How does a mentality generate cognizance ? In the estimator age , it is not hard to imagine how a computing car might construct , put in and spit out the information that ‘ I am alive , I am a person , I have store , the wind is cold , the grass is green , ’ and so on . But how does a brain become aware of those proposition ? The philosopher David Chalmers has claimed that the first question , how a encephalon reckon entropy about itself and the surrounding earthly concern , is the ‘ easy ’ problem of consciousness . The second question , how a brain becomes aware of all that computed stuff , is the ‘ hard ’ job .
I believe that the easy and the hard trouble have gotten switched around . The sheer scale leaf and complexity of the wit ’s vast computations makes the easy problem monumentally hard to figure out . How the genius attribute the dimension of knowingness to itself is , by contrast , much easier . If nothing else , it would come out to be a more special solidifying of computations . In my laboratory at Princeton University , we are working on a specific hypothesis of awareness and its basis in the brainpower . Our hypothesis explains both the apparent awareness that we can attribute to Kevin and the direct , first - person linear perspective that we have on our own experience . And the easy way to put in it is to trip about half a billion years back in time .
