Plato discusses theories of knowledge throughout his famous dialogue, the Theaetetus.
He discusses many different ways of learning and attempts to define knowledge. Plato does this through a conversation between a few characters: Socrates, the famous philosopher; Theodorus, an aged friend and philosopher of Socrates; and Theaetetus, a young man who is introduced to Socrates before a discussion. One aspect of knowledge which they review is perception. It is defined and explained by Socrates, to the young and innocent Theaetetus.
Perception is defined by Floyd H. Allport in his book, Theories of Perception and the Concept of Structure, as “the way things look to us, or the way they sound, feel, taste, or smell.” It is not the way things are exactly, but the way we see them; or because it involves all of the five senses, the way we perceive them. Perception is not restricted to sight only, the world has countless numbers of sounds, smells, and textures.
Perception is “the way things look to us” because even though something might seem to be one way, it is another. For example, the Muller-Lyer illusion makes people see two lines of different lengths, while the lines are the same size. This illustrates the fact that just because you perceive something to be a certain way does not mean that it is true.
Truth and perception do not necessarily coincide. This is also true with belief. When seeing something that is too far fetched to be real, then you find it hard to believe.
Perception is merely an “experience [which] is just a stage along the causal process leading to belief.” Perception is not truth or belief, but it is an important (however, not necessary) step to reaching them.
In Plato’s Theaetetus, the three characters in the conversation have a discussion on perception and how it relates to the world. Plato recounts Socrates telling the young
Theaetetus how, contrary to his belief, perception is not knowledge. Perception is too varied, Socrates says. He gives the example of a breeze blowing; one man can be made cold from the wind, while the man next to him might not be cold at all. The blowing wind is the same temperature, but as defined above, perception is “the way things look to us.
What is sense perception? Everything we perceive in our senses can be misleading and an illusion. In the article “Perception and Reality” by Keith Wilson (see Article 1), the author goes over some of the aspects of how our perception deceives us to believe in things that aren’t there to begin with. For example are colors real? Well that is relevantly dependent on what is considered real, because real again is a perception of a single individual collecting information and making “sense” out of it. A color being real or not is dependent on how we see it through our eyes, we can 't say that my blue is the same as your blue. We can 't know for sure if what we are seeing for ourselves, is the same as what the person that views that same thing sees
The simple optical illusions used by Ariely show us just how easily our senses can lead our judgments to be distorted. The first illusion was an animation of Shepard’s Tables; an example of size-constancy expansion first published by Roger Shepard as “Turning the Tables”. We know the two tables are the same length but yet why does one table appear to be longer than the other? In this case it is because the angles suggest depth and perspective and the brain wrongly believes one table is longer and while the other in shorter. It is interesting that despite us knowing that the tables are in fact the same length, we still perceive them to be different lengths; despite us knowing the truth, we could not get our minds to see reality as it really is. In the second example, Ariely shows the ...
One of the main points of Plato’s philosophy was that he believed that people should not so easily trust their senses. In “The Allegory of the Cave”, Plato argues that what we perceive of the world through our sense does not give us the entire picture of what is really there. He states that what we can see is only shadows of what is true, but since we are born believing what we see, we don’t know that there is anything missing at all. Plato believed that in the “knowable realm”, the form of the good, the ultimate truth, is the last thing that we can see, which requires more effort that simply perceiving it. This ultimate truth can only be found through being able to not only perceive, but to be dragged out of the cave, or to be able to think. He likely believed this because through education, he felt that there was an ordering occurring in the mind that allowed for thoughts to become more focused, and clearer. As these thoughts became clearer, s...
through our senses is actually an accurate interpretation of reality. After we’ve established that our senses aren’t
Without perception, in our illusions and hallucinations, we lose “our sense of beings,” (Capra). Lost in “isolation,” (Capra) perhaps lost within our own illusion, our abstractions, we lose the ability to judge, to dichotomize, reality from illusions, right from wrong.
When you see a bowl of soup with steam dusting the top of it in a magazine or a commercial, you think that it is hot and delicious. However, there is a steamed towel in that back of it making it look fresh and burning. That is what perception and reality is. Perception is believing in what you see and reality is knowing with facts and not assuming. Therefore, perception is not reality.
What we see in some things can based on our past experiences and things we’vewe have seen before. If you ever look at the clouds during the day and try to decide what you see and then ask someone else what they see it’sit is about very little chance that everyone will see the same thing. This is what I think of
In Plato’s Theaetetus, Socrates examines the first definition of knowledge that theaetetus gives that knowledge is perception. Socrates gives us many example that both supports and refutes that knowledge is perception. The basic claim from Protagoras is that truth is based on the perception of every man. This means that things are to any person as they seem to that person. Socrates explains to us Protagoras’s view with the cold wind example.

Our five senses –sight, hearing, smell, taste and touch help the ways in which we perceive the world around us. And while they seem to work independently at time they can effect each other and the way we comprehend something. Seeing something pretty, touching something soft, eating something cold and smelling something rotten are the sense we use to connect with the world around us and will all effect how we move forward in that situation. When you look at the top picture say the color of the word not the word itself. It is harder than it seems and takes a little practice to do it efficiently. It is because we see the spelling we were taught not the color it was written in. It is hard to process it the other way, but not impossible. Take the bottom picture for another example is this a
Socrates is a philosopher known for his wisdom, and in the case of Meno, a dialogue between Meno and Socrates; he examines what it is to have virtue and the difference between opinion and knowledge. According to Socrates, the difference between the two subjects, knowledge and opinion, is their stability to be questioned and disputed. He demonstrated this with an analogy of a statue that is well grounded and is more secure that one that is not relating to knowledge vs. opinion.
With each of our senses (sight, smell, touch, taste, and hear), information is transmitted to the brain. Psychologists find it problematic to explain the processes in which the physical energy that is received by the sense organs can form the foundation of perceptual experience. Perception is not a direct mirroring of stimulus, but a compound messy pattern dependent on the simultaneous activity of neurons. Sensory inputs are somehow converted into perceptions of laptops, music, flowers, food, and cars; into sights, sounds, smells, taste ...
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
"I'll believe it when I see it:" is one of many common catch phrases included in our every day vernacular. A person who declares this is asserting that they will not be fooled by another's assumptions or perceptions of the world. This understanding raises a great sense of security within us, concerning the things that we do see, and inversely, an unavoidable sense of insecurity in those beliefs that are not supported by vision. Do you believe in Ghosts? Angels? Out of body experiences? Would you believe if you could see them? Maybe not. But it is possible to offer those who are withholding there stamp of approval on things that exist but cannot be seen, a better summary of evidence, which could make the inability to see something an invalid criteria for belief. Could a summary of evidence be compiled that would support this: Our vision is incomplete, incorrect, and can even be as misleading as to create something within the brain that does not exist at all, shedding light on a brain that is more of a visionary, and less of a reporter.
Senses merely hinder and obscure the truth. Sight for example can be fooled easily with optical illusions
