perception (for myself)

Every thing is a perception or interpretation. This is obvious when we are discussing concepts but not so easy to realise when it comes to mundane things like seeing and hearing..
seeing is actually interpretation isnt it.. there is no such thing as reality which we can figure out. it is always our interpretation. some objective some subjective..
I got a headache thinking about this but its kind of repetitive thought, the repition stops after wrtiing it down...
Okay so, When i see a something red - Red - frequency of light between x-y is interpreted as red by my thinking brain..or say before that my eye also has a range of sensing right? resolution.. x1 to y1 is approximated and shown as one signal to my head.. more range more differenciation probably then my conscious head ... my eye can differentiate between two reds which my head probably cant. but when i see a picture with shading with these two reds my eye ( and head) can make out.
how much do we acutlaly see objectively? its all subjective... when searching for something - why does my mom see by pyjama and I dont see it... how much of what we see is acutlaly seeing and how much is thinking. how much of our senses are actually coloured by subjectivity.
which are the really objective parts of our sensing.. most of the objective part is automatic and out of conscious control i think, like measuring distance between an object and me.. calcuating its speed accelatartion trajectory guessing its weight.. ducking in time to avoid it if it is falling on me... not subjective. learnt yes but not subjective..and most of what I ve talked about is not really seeing :D
when i see a tree, how do i know I see a tree, it is just 10 pixels green 2 pixels brown so on .. it has to be mapped on to my experience matched to my previous image of tree heuristically approximtaed as tree.. most of our seeing is like this - at this level. Lot of image processing involved here.. lot of decisions - bamboo -shrub or tree? and some edge cases like bonsai - tree or plant. etc.
Also when we see a view- all the objects in our view are probably saved as a link list ( or binary tree-whatever) of objects just like in an image editor in vector view. and each of these object nodes probably has a link to the object database reference in the brain. data base has more info about objects like tree - doesnot move, living, huge etc. each person has different attributes saved in this database. for example for me tree is saved as living, for a wood cutter - it is saved as makes money :) for a bird - home.. so on. so how a tree is interpreted is based more on my experince in this world rather than the content of the image produced by the eye( which -is reality?atleast is it objective)
Can we suspend all interpretation and just seen the colors as it is? I tried and i got headache. again!! :) ( and I didnt succeed)
There is this picture which can be interpreted as old lady young girl(one of my older posts).. It is acutally just black markings on white background isnt it? even concept of background as being white..? comes from using paper...its just white and black pixels.. that is the reality. kind of useless?? the reality is useless with out interpretation and subjectivity... seeing an old lady young girl is far more interesting .. I wish we could retian our consciousness and enter the mind of an insect or something and see how it thinks how it feels.. wow that would show us what all we take for granted and how differnent interpretations can be...and how different the so called reality can look.
Or would it? I am reading blind watchmaker by Richar dawkins.. he is not really very focused in this book and talks about a lot of things..
he talks bout bats and their sonars to show how complex biological equipment can evolve by natural selection rather than by design and explains the equiment in detail . Bats interpret the world using sound, its quite complex how this sonar works, just like our eye.. but .. does the bat know the working of the sonar ( hardware/software) ? no? so how does a bat feel with all those echos coming in? and the calculatins and everyhting. probably just like me.. the world that I see is after all a model made up by the mind to interpret reality. so the bats model - may be same as ours... using sound instead of light.. colors.. may be they use colors to indicate something else like distance? or speed of the objects.. density?
(so Mr there is no god is actually talking about exactly same thing as the spritual books what u see is a model and not reality. :) )
what ever complex equipment we have we finally do rely on the models that our brain makes, dont we? so reality is just as out of reach if I do get into another brain as when I am in mine.
Its so easy to confuse a model with reality - sine wave.. does a sine wave look like that.. up and down? no... its just a graph which we made so that we can understand how a sine wave works. but its so easy to forget that. Nature follows rules of physics??? no it doesnot. nature is just the way it is, our rules of physics is just our attempt to understand the world. first of all we have a model in our head and we are making another model to understand that model :)
phew, I think i am done.
