Knowledge Case Essay Sample

Human senses do non give much cognition to the universe as it truly is ; they chiefly function to make a physical representation of the universe that the encephalon can understand. Human senses can observe and have true information. but the encephalon processes this information to try to organize an image of the universe that is consistent. non as it genuinely is. On the other manus. some people might state that human senses can give us absolute cognition as the universe is ; it is merely the manner that humans organize information that leads to the common idea that what we perceive is non genuinely what is.

Human senses are. in the most basic of definitions. ways that the head receives information from the outside universe. Whether this is through touch. odor. gustatory sensation. sight. or hearing. does non count ; it is still information from the outside universe. in this instance. categorized into groups. This means that what information that is traveling into. for case. the oculus. is true natural information of the universe ; it is the universe as it truly is. The encephalon does non cognize this information even exists in its natural signifier. as processing takes over subconsciously.

Out of processing. comes the physical representation of our universe. The operative word in that sentence is representation. Human senses can merely give one a representation of the universe harmonizing to one’s ain capable organisational accomplishments and the information gathered by one’s senses. This restriction on cognition of the true universe occurs because the natural information. the universe as it genuinely is. is processed and warped until the human encephalon can grok the information and bring forth a consistent thought of what is outside of the head. This processing of information in order to make a consistent universe can be seen in many semblances. In the “grid illusion” . the white musca volitanss on a black planar grid appear to spontaneously alter from white to black. This self-generated and rapid alteration in colour does non really go on. What is really go oning is a struggle between the two beginnings of information. the right and left oculus. and a false representation of the universe created by the mind’s desire for a consistent universe.

When the encephalon scans the semblance. traveling left and right fleetly. the eyes focal point on critical points of the semblance. glazing over other parts of the semblance. Therefore. the encephalon. trying to organize a coherent unicolor image. assumes that the parts of the semblance it can non garner information from are merely black. like the remainder of the image. However. they are non. Therefore. whenever the encephalon receives information on those false parts ; the encephalon realizes that it was incorrect in presuming those parts were black and changes the black parts in the physical representation of the semblance to white parts. This procedure happens quickly and this consequences in the effect of the points turning from black to white often. Therefore. the semblance of the self-generated changing of colour of points from black to white and frailty versa is caused by the processing of the encephalon seeking to make a consistent version of the universe.

In add-on. the senses receive this pure and true natural information instead randomly. Therefore. the information gathered is besides undependable when refering cognition about the true universe. For illustration. the rods and cones contained within the cornea of the human oculus are used to observe visible radiation and colour. severally. However. when the cornea is non exposed to voluminous sums of visible radiation for a long period. the cornea’s rods become altered to the darker environment. Then. when the cornea is introduced to a light-rich environment. the cornea receives this information as being highly bright. to the point where there is no manner for the cones to map. and therefore there is no colour. In this information gathered from the true universe. there is merely highly bright white visible radiation. However. in many instances. this is non true information ; the light-rich environment is non entirely comprised of bright white visible radiation. That is merely a misconception caused by the cornea’s undependability. However. this undependability in the cornea merely lasts for a limited sum of clip. three to four seconds maximal. because the encephalon realizes the job and repair it. Even though the undependability is short lived. it is important in the manner it portrays the hit-or-miss manner natural information is gained through perceptual experience.

Therefore. because the senses are besides undependable in how they gather this true information. there is uncertainness contained within the true information the encephalon receives. Then. when the encephalon processes this information. this uncertainness is greatly increased because the encephalon is falsifying already deformed information in an effort to uncover a representation of the universe. Overall. the terminal of the processing comes a blemished version of the universe.

The job of human organisation becomes much more obvious if the counter thesis is more greatly analyzed. For illustration. the cornea receives the information of a beam of visible radiation with the wavelength of 494 nanometres. This wavelength is really near the colour of violet while still being within the boundaries of blue’s wavelength. The encephalon so processes this information ; the wavelength of 494 nanometres that is. and so organizes it by stating that the visible radiation is bluish. All this information is right. nevertheless there is difference between what the colourss genuinely are. This is because colourss are learned and therefore colour names are non a priori. but alternatively are a posteriori. Therefore. when the two people come together and seek to form the same visible radiation by colour. jobs occur as their encephalons could hold organized the colourss otherwise because they each learned the colourss otherwise. Therefore. it is non how the universe truly is that can non be seen. it is merely the manner worlds try to form the true universe that really can non suit the entireness of the universe. It is the subjectiveness of the a posteriori organisation accomplishments that cause the ruin of perceptual experience.

This is a right statement. the universe can be understood through perceptual experience. What is really doing people to non hold true cognition of the universe is the organisational accomplishments they learn after they are born. However. organisation is a wholly a priori phenomenon. For illustration. babes organize colourss really merely. black vs. white. They organize black into association of void and white into association with being. Therefore. homo sort has a demand to form and categorise the information against and with antecedently assumed information to understand the universe. Thus. while it is true that perceptual experience can be used entirely to derive cognition about the universe as it truly is. the job arises whenever one attempts to form the information into a consistent image. This is a little job because unrefined perceptual cognition is useless as it is random information scattered around the encephalon.

All in all. human senses can non to the full give us knowledge about the universe as it truly is. This is due to the haphazard manner the physical receptors of our senses gather information. the heavy processing of information to organize a consistent physical representation of the universe. and a differing a posteriori organisational accomplishments. which are used to come to the consistent representation of the universe. However. some people do believe that cognition of the universe can be gained entirely on the perceptual information gained from the perceptual experience variety meats.
